Ruby news: CVE-2017-17742: HTTP response splitting in WEBrick If a script accepts an external input and outputs it without
modification as a part of HTTP responses, an attacker can use newline
characters to deceive the clients that the HTTP response header is
stopped at there, and can inject fake HTTP responses after the newline
characters to show malicious contents to the clients. CVE-2018-6914: Unintentional file and directory creation with
directory traversal in tempfile and tmpdir Dir.mktmpdir method introduced by tmpdir library accepts the prefix
and the suffix of the directory which is created as the first parameter.
The prefix can contain relative directory specifiers "../", so this
method can be used to target any directory. So, if a script accepts an
external input as the prefix, and the targeted directory has
inappropriate permissions or the ruby process has inappropriate
privileges, the attacker can create a directory or a file at any
directory. CVE-2018-8777: DoS by large request in WEBrick If an attacker sends a large request which contains huge HTTP headers,
WEBrick try to process it on memory, so the request causes the
out-of-memory DoS attack. CVE-2018-8778: Buffer under-read in String#unpack String#unpack receives format specifiers as its parameter, and can
be specified the position of parsing the data by the specifier @. If a
big number is passed with @, the number is treated as the negative
value, and out-of-buffer read is occurred. So, if a script accepts an
external input as the argument of String#unpack, the attacker can read
data on heaps. CVE-2018-8779: Unintentional socket creation by poisoned NUL byte in
UNIXServer and UNIXSocket UNIXServer.open accepts the path of the socket to be created at the
first parameter. If the path contains NUL (\0) bytes, this method
recognize that the path is completed before the NUL bytes. So, if a
script accepts an external input as the argument of this method, the
attacker can make the socket file in the unintentional path. And,
UNIXSocket.open also accepts the path of the socket to be created at
the first parameter without checking NUL bytes like UNIXServer.open.
So, if a script accepts an external input as the argument of this
method, the attacker can accepts the socket file in the unintentional
path. CVE-2018-8780: Unintentional directory traversal by poisoned NUL byte
in Dir Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the
target directory as their parameter. If the parameter contains NUL (\0)
bytes, these methods recognize that the path is completed before the
NUL bytes. So, if a script accepts an external input as the argument of
these methods, the attacker can make the unintentional directory
traversal. Node.js reports: Node.js 6.x and later include a debugger protocol (also known as "inspector") that can be activated by the --inspect and related command line flags. This debugger service was vulnerable to a DNS rebinding attack which could be exploited to perform remote code execution. The 'path' module in the Node.js 4.x release line contains a potential regular expression denial of service (ReDoS) vector. The code in question was replaced in Node.js 6.x and later so this vulnerability only impacts all versions of Node.js 4.x. The HTTP parser in all current versions of Node.js ignores spaces in the Content-Length header, allowing input such as Content-Length: 1 2 to be interpreted as having a value of 12. The HTTP specification does not allow for spaces in the Content-Length value and the Node.js HTTP parser has been brought into line on this particular difference. The WebKit team reports many vulnerabilities. Please reference the CVE/URL list for details. Google Chrome Releases reports: 1 security fix in this release, including: The OpenSSL project reports: GitLab reports: There were multiple server-side request forgery issues in the Services feature.
- An attacker could make requests to servers within the same network of the GitLab
- instance. This could lead to information disclosure, authentication bypass, or
- potentially code execution. This issue has been assigned
- CVE-2018-8801.
Node.js Inspector DNS rebinding vulnerability (CVE-2018-7160)
'path' module regular expression denial of service (CVE-2018-7158)
Spaces in HTTP Content-Length header values are ignored (CVE-2018-7159)
Constructed ASN.1 types with a recursive definition (such as can be
found in PKCS7) could eventually exceed the stack given malicious input
with excessive recursion. This could result in a Denial Of Service
attack. There are no such structures used within SSL/TLS that come from
untrusted sources so this is considered safe.
There is an overflow bug in the AVX2 Montgomery multiplication
procedure used in exponentiation with 1024-bit moduli. This only
affects processors that support the AVX2 but not ADX extensions
like Intel Haswell (4th generation).

There was an issue with the GitLab omniauth-auth0
configuration
- which resulted in the Auth0 integration signing in the wrong users.
The Mozilla Foundation reports:
CVE-2018-5148: Use-after-free in compositor
A use-after-free vulnerability can occur in the compositor during certain graphics operations when a raw pointer is used instead of a reference counted one. This results in a potentially exploitable crash.
OSS-Security list:
There is a possible XSS vulnerability in rails-html-sanitizer. The gem allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments, and these attributes can lead to an XSS attack on target applications.
This issue is similar to CVE-2018-8048 in Loofah.

MITRE reports:
SQLite databases whose schema is corrupted using a CREATE TABLE AS statement could cause a NULL pointer dereference, related to build.c and prepare.c.
Sanitize release:
Fixed an HTML injection vulnerability that could allow XSS.
When Sanitize <= 4.6.2 is used in combination with libxml2 >= 2.9.2, a specially crafted HTML fragment can cause libxml2 to generate improperly escaped output, allowing non-whitelisted attributes to be used on whitelisted elements.
Sanitize now performs additional escaping on affected attributes to prevent this.
GitHub issue:
This issue has been created for public disclosure of an XSS / code injection vulnerability that was responsibly reported by the Shopify Application Security Team.
Loofah allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments.
MITRE reports:
In Jupyter Notebook before 5.4.1, a maliciously forged notebook file can bypass sanitization to execute JavaScript in the notebook context. Specifically, invalid HTML is 'fixed' by jQuery after sanitization, making it dangerous.
Florian Grunow reports:
An attacker able to exploit this vulnerability can extract files of the server the application is running on. This may include configuration files, log files and additionally all files that are readable for all users on the system. This issue is post-authentication. That means an attacker would need valid credentials for the application to log in or needs to exploit an additional vulnerability of which we are not aware of at this point of time.
An attacker would also be able to delete files on the system, if the user running the application has the rights to do so.
Does this issue affect me?
Likely yes, if you are using Squirrelmail. We checked the latest development version, which is 1.5.2-svn and the latest version available for download at this point of time, 1.4.22. Both contain the vulnerable code.
SchedMD reports:
Several issues were discovered with incomplete sanitization of user-provided text strings, which could potentially lead to SQL injection attacks against SlurmDBD itself. Such exploits could lead to a loss of accounting data, or escalation of user privileges on the cluster.
NVD reports:
Xiph.Org libvorbis 1.3.5 allows Remote Code Execution upon freeing uninitialized memory in the function vorbis_analysis_headerout() in info.c when vi->channels<=0, a similar issue to Mozilla bug 550184.
In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability exists in the function mapping0_forward() in mapping0.c, which may lead to DoS when operating on a crafted audio file with vorbis_analysis().
The Mozilla Foundation reports:
CVE-2018-5146: Out of bounds memory write in libvorbis
An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.
CVE-2018-5147: Out of bounds memory write in libtremor
The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms.
Theodore Y. Ts'o reports:
Fixed some potential buffer overrun bugs in the blkid library and in the fsck program.
A number of issues relating to speculative execution were found last year and publicly announced January 3rd. Two of these, known as Meltdown and Spectre V2, are addressed here.
CVE-2017-5754 (Meltdown) - ------------------------
This issue relies on an affected CPU speculatively executing instructions beyond a faulting instruction. When this happens, changes to architectural state are not committed, but observable changes may be left in micro- architectural state (for example, cache). This may be used to infer privileged data.
CVE-2017-5715 (Spectre V2) - --------------------------
Spectre V2 uses branch target injection to speculatively execute kernel code at an address under the control of an attacker.
An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser).
Due to a lack of strict checking, an attacker from a trusted host can send a specially constructed IP packet that may lead to a system crash.
Additionally, a use-after-free vulnerability in the AH handling code could cause unpredictable results.
Access to out of bounds or freed mbuf data can lead to a kernel panic or other unpredictable results.
Adobe reports:
- This update resolves a use-after-free vulnerability that could lead to remote code execution (CVE-2018-4919).
- This update resolves a type confusion vulnerability that could lead to remote code execution (CVE-2018-4920).

Simon Butcher reports:
- When the truncated HMAC extension is enabled and CBC is used, sending a malicious application packet can be used to selectively corrupt 6 bytes on the peer's heap, potentially leading to a crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.
- When RSASSA-PSS signature verification is enabled, sending a maliciously constructed certificate chain can be used to cause a buffer overflow on the peer's stack, potentially leading to crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.

ISC reports:
Failure to properly bounds check a buffer used for processing DHCP options allows a malicious server (or an entity masquerading as a server) to cause a buffer overflow (and resulting crash) in dhclient by sending a response containing a specially constructed options section.
A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash.

- CVE-2018-1058: Uncontrolled search path element in pg_dump and other client applications
Strongswan Release Notes reports:
Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS signatures that was caused by insufficient input validation. One of the configurable parameters in algorithm identifier structures for RSASSA-PSS signatures is the mask generation function (MGF). Only MGF1 is currently specified for this purpose. However, this in turn takes itself a parameter that specifies the underlying hash function. strongSwan's parser did not correctly handle the case of this parameter being absent, causing an undefined data read. his vulnerability has been registered as CVE-2018-6459.
Laurent Delosieres, Secunia Research at Flexera Software reports:
Secunia Research has discovered a vulnerability in libsndfile, which can be exploited by malicious people to disclose potentially sensitive information. The vulnerability is caused due to an error in the "aiff_read_chanmap()" function (src/aiff.c), which can be exploited to cause an out-of-bounds read memory access via a specially crafted AIFF file. The vulnerability is confirmed in version 1.0.28. Other versions may also be affected.

Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorised to access them.
The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected.
Shibboleth consortium reports:
Shibboleth SP software vulnerable to additional data forgery flaws
The XML processing performed by the Service Provider software has been found to be vulnerable to new flaws similar in nature to the one addressed in an advisory last month.
These bugs involve the use of other XML constructs rather than entity references, and therefore required additional mitigation once discovered. As with the previous issue, this flaw allows for changes to an XML document that do not break a digital signature but can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.
As before, the use of XML Encryption is a significant mitigation, but we have not dismissed the possibility that attacks on the Response "envelope" may be possible, in both the original and this new case. No actual attacks of this nature are known, so deployers should prioritize patching systems that expect to handle unencrypted SAML assertions.
An updated version of XMLTooling-C (V1.6.4) is available that protects against these new attacks, and should help prevent similar vulnerabilities in the future.
Unlike the previous case, these bugs are NOT prevented by any existing Xerces-C parser version on any platform and cannot be addressed by any means other than the updated XMLTooling-C library.
The Service Provider software relies on a generic XML parser to process SAML responses and there are limitations in older versions of the parser that make it impossible to fully disable Document Type Definition (DTD) processing.
Through addition/manipulation of a DTD, it's possible to make changes to an XML document that do not break a digital signature but are mishandled by the SP and its libraries. These manipulations can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.
While newer versions of the xerces-c3 parser are configured by the SP into disallowing the use of a DTD via an environment variable, this feature is not present in the xerces-c3 parser before version 3.1.4, so an additional fix is being provided now that an actual DTD exploit has been identified. Xerces-c3-3.1.4 was committed to the ports tree already on 2016-07-26.

Hank Leininger reports:
Bugs in Git, Subversion, and Mercurial were just announced and patched which allowed arbitrary local command execution if a malicious name was used for the remote server, such as starting with - to pass options to the ssh client: git clone ssh://-oProxyCommand=some-command... CVS has a similar problem with the -d option:
Tested vanilla CVS 1.12.13, and Gentoo CVS 1.12.12-r11.
LibreOffice reports:
LibreOffice Calc supports a WEBSERVICE function to obtain data by URL. Vulnerable versions of LibreOffice allow WEBSERVICE to take a local file URL (e.g file://) which can be used to inject local files into the spreadsheet without warning the user. Subsequent formulas can operate on that inserted data and construct a remote URL whose path leaks the local data to a remote attacker.
In later versions of LibreOffice without this flaw, WEBSERVICE has now been limited to accessing http and https URLs along with bringing WEBSERVICE URLs under LibreOffice Calc's link management infrastructure.
Note: This vulnerability has been identified upstream as CVE-2018-1055, but NVD/Mitre are advising it's a reservation duplicate of CVE-2018-6871 which should be used instead.
Louis Dion-Marcil reports:
Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses.
This problem allows a remote server delivering certain ESI response syntax to trigger a denial of service for all clients accessing the Squid service.
Due to unrelated changes Squid-3.5 has become vulnerable to some regular ESI server responses also triggering this issue.
This problem is limited to the Squid custom ESI parser. Squid built to use libxml2 or libexpat XML parsers do not have this problem.
Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses or downloading intermediate CA certificates.
This problem allows a remote client delivering certain HTTP requests in conjunction with certain trusted server responses to trigger a denial of service for all clients accessing the Squid service.
The Asterisk project reports:
AST-2018-004 - When processing a SUBSCRIBE request the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request.

MITRE reports:
Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, alows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.
MITRE reports:
Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive.
mpv developers report:
mpv through 0.28.0 allows remote attackers to execute arbitrary code via a crafted web site, because it reads HTML documents containing VIDEO elements, and accepts arbitrary URLs in a src attribute without a protocol whitelist in player/lua/ytdl_hook.lua. For example, an av://lavfi:ladspa=file= URL signifies that the product should call dlopen on a shared object file located at an arbitrary local pathname. The issue exists because the product does not consider that youtube-dl can provide a potentially unsafe URL.
Mark Sapiro reports:
An XSS vulnerability in the user options CGI could allow a crafted URL to execute arbitrary javascript in a user's browser. A related issue could expose information on a user's options page without requiring login.

Django release notes:
CVE-2018-6188: Information leakage in AuthenticationForm
A regression in Django 1.11.8 made AuthenticationForm run its confirm_login_allowed() method even if an incorrect password is entered. This can leak information about a user, depending on what messages confirm_login_allowed() raises. If confirm_login_allowed() isn't overridden, an attacker enter an arbitrary username and see if that user has been set to is_active=False. If confirm_login_allowed() is overridden, more sensitive details could be leaked.
This issue is fixed with the caveat that AuthenticationForm can no longer raise the "This account is inactive." error if the authentication backend rejects inactive users (the default authentication backend, ModelBackend, has done that since Django 1.10). This issue will be revisited for Django 2.1 as a fix to address the caveat will likely be too invasive for inclusion in older versions.

Pedro Sampaio reports:
A flaw was found in dovecot 2.0 up to 2.2.33 and 2.3.0. A abort of SASL authentication results in a memory leak in Dovecot auth client used by login processes. The leak has impact in high performance configuration where same login processes are reused and can cause the process to crash due to memory exhaustion.
The cURL project reports:
libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequest hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request.

Google Project Zero reports:
The transmission bittorrent client uses a client/server architecture, the user interface is the client which communicates to the worker daemon using JSON RPC requests.
As with all HTTP RPC schemes like this, any website can send requests to the daemon listening on localhost with XMLHttpRequest(), but the theory is they will be ignored because clients must prove they can read and set a specific header, X-Transmission-Session-Id. Unfortunately, this design doesn't work because of an attack called "DNS rebinding". Any website can simply create a dns name that they are authorized to communicate with, and then make it resolve to localhost.
Exploitation is simple, you could set script-torrent-done-enabled and run any command, or set download-dir to /home/user/ and then upload a torrent for .bashrc.
Shibboleth consortium reports:
Shibboleth SP software vulnerable to forged user attribute data
The Service Provider software relies on a generic XML parser to process SAML responses and there are limitations in older versions of the parser that make it impossible to fully disable Document Type Definition (DTD) processing.
Through addition/manipulation of a DTD, it's possible to make changes to an XML document that do not break a digital signature but are mishandled by the SP and its libraries. These manipulations can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.
While newer versions of the xerces-c3 parser are configured by the SP into disallowing the use of a DTD via an environment variable, this feature is not present in the xerces-c3 parser before version 3.1.4, so an additional fix is being provided now that an actual DTD exploit has been identified. Xerces-c3-3.1.4 was committed to the ports tree already on 2016-07-26.

Mozilla Foundation reports:
Jann Horn of Google Project Zero Security reported that speculative execution performed by modern CPUs could leak information through a timing side-channel attack. Microsoft Vulnerability Research extended this attack to browser JavaScript engines and demonstrated that code on a malicious web page could read data from other web sites (violating the same-origin policy) or private data from the browser itself.
Since this new class of attacks involves measuring precise time intervals, as a parti al, short-term, mitigation we are disabling or reducing the precision of several time sources in Firefox. The precision of
performance.now()
has been reduced from 5μs to 20μs, and theSharedArrayBuffer
feature has been disabled because it can be used to construct a high-resolution timer.
OTRS reports:
An attacker who is logged into OTRS as an agent can request special URLs from OTRS which can lead to the execution of shell commands with the permissions of the web server user.
An attacker who is logged into OTRS as a customer can use the ticket search form to disclose internal article information of their customer tickets.
An attacker who is logged into OTRS as an agent can manipulate form parameters and execute arbitrary shell commands with the permissions of the OTRS or web server user.
An attacker can send a specially prepared email to an OTRS system. If this system has cookie support disabled, and a logged in agent clicks a link in this email, the session information could be leaked to external systems, allowing the attacker to take over the agent’s session.
The Legion of the Bouncy Castle reports:
Release: 1.59
CVE-2017-13098 ("ROBOT"), a Bleichenbacher oracle in TLS when RSA key exchange is negotiated. This potentially affected BCJSSE servers and any other TLS servers configured to use JCE for the underlying crypto - note the two TLS implementations using the BC lightweight APIs are not affected by this.

We consider this vulnerability to be critical.
The Asterisk project reports:
A select set of SIP messages create a dialog in Asterisk. Those SIP messages must contain a contact header. For those messages, if the header was not present and using the PJSIP channel driver, it would cause Asterisk to crash. The severity of this vulnerability is somewhat mitigated if authentication is enabled. If authentication is enabled a user would have to first be authorized before reaching the crash point.
The MariaDB project reports:
Fixes for the following security vulnerabilities: CVE-2017-15365
Jeriko One reports:
The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.
The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.
The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does not apply the sanitize_paths protection mechanism to pathnames found in "xname follows" strings (in the read_ndx_and_attrs function in rsync.c), which allows remote attackers to bypass intended access restrictions.
Etienne Stalmans from the Heroku product security team reports:
There is a command injection vulnerability in Net::FTP bundled with Ruby.

Phusion reports:
The cPanel Security Team discovered a vulnerability in Passenger that allows users to list the contents of arbitrary files on the system. CVE-2017-16355 has been assigned to this issue.
the freedesktop.org project reports:
A non-privileged X client can instruct X server running under root to open any file by creating own directory with "fonts.dir", "fonts.alias" or any font file being a symbolic link to any other file in the system. X server will then open it. This can be issue with special files such as /dev/watchdog.
The freedesktop.org project reports:
If a pattern contains '?' character, any character in the string is skipped, even if it is '\0'. The rest of the matching then reads invalid memory.
Without the checks a malformed PCF file can cause the library to make atom from random heap memory that was behind the `strings` buffer. This may crash the process or leak information.
The freedesktop.org project reports:
It is possible to trigger heap overflows due to an integer overflow while parsing images and a signedness issue while parsing comments.
The integer overflow occurs because the chosen limit 0x10000 for dimensions is too large for 32 bit systems, because each pixel takes 4 bytes. Properly chosen values allow an overflow which in turn will lead to less allocated memory than needed for subsequent reads.
The signedness bug is triggered by reading the length of a comment as unsigned int, but casting it to int when calling the function XcursorCommentCreate. Turning length into a negative value allows the check against XCURSOR_COMMENT_MAX_LEN to pass, and the following addition of sizeof (XcursorComment) + 1 makes it possible to allocate less memory than needed for subsequent reads.
MITRE reports:
gozilla.c in GNU GLOBAL 4.8.6 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL.
The Jenkins project reports:
A race condition during Jenkins startup could result in the wrong order of execution of commands during initialization.
On Jenkins 2.81 and newer, including LTS 2.89.1, this could in rare cases (we estimate less than 20% of new instances) result in failure to initialize the setup wizard on the first startup.
There is a very short window of time after startup during which Jenkins may no longer show the "Please wait while Jenkins is getting ready to work" message, but Cross-Site Request Forgery (CSRF) protection may not yet be effective.
Node.js reports:
Data Confidentiality/Integrity Vulnerability - CVE-2017-15896
Node.js was affected by OpenSSL vulnerability CVE-2017-3737 in regards to the use of SSL_read() due to TLS handshake failure. The result was that an active network attacker could send application data to Node.js using the TLS or HTTP2 modules in a way that bypassed TLS authentication and encryption.
Uninitialized buffer vulnerability - CVE-2017-15897
Node.js had a bug in versions 8.X and 9.X which caused buffers to not be initialized when the encoding for the fill value did not match the encoding specified. For example, 'Buffer.alloc(0x100, "This is not correctly encoded", "hex");' The buffer implementation was updated such that the buffer will be initialized to all zeros in these cases.
Also included in OpenSSL update - CVE 2017-3738
Note that CVE 2017-3738 of OpenSSL-1.0.2 affected Node but it was low severity.

The Asterisk project reports:
If a compound RTCP packet is received containing more than one report (for example a Receiver Report and a Sender Report) the RTCP stack will incorrectly store report information outside of allocated memory potentially causing a crash.
libxml2 developers report:
The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure.
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictAddString function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for CVE-2016-1839.
Invoking SSL_read()/SSL_write() while in an error state causes data to be passed without being decrypted/encrypted directly from the SSL/TLS record layer.
In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. [CVE-2017-3737]
There is an overflow bug in the x86_64 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). [CVE-2017-3738] This bug only affects FreeBSD 11.x.
Applications with incorrect error handling may inappropriately pass unencrypted data. [CVE-2017-3737]
Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected and analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
Attacks against DH1024 are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701. [CVE-2017-3738]

The OpenSSL project reports:
- Read/write after SSL object in error state (CVE-2017-3737)
OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer.- rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible, because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.
If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer overread. [CVE-2017-3735]
There is a carry propagating bug in the x86_64 Montgomery squaring procedure. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. [CVE-2017-3736] This bug only affects FreeBSD 11.x.
Application using OpenSSL may display erroneous certificate in text format. [CVE-2017-3735]
Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected, analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. [CVE-2017-3736]
The kernel does not properly clear the memory of the kld_file_stat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible.
Some bytes from the kernel stack can be observed in userspace.
Named paths are globally scoped, meaning a process located in one jail can read and modify the content of POSIX shared memory objects created by a process in another jail or the host system.
A malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. This memory region might be executed by applications trusting the shared memory, like Squid.
This issue could lead to a Denial of Service or local privilege escalation.
Not all information in the struct ptrace_lwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information of the kernel stack of the thread is possible from the debugger.
Some bytes from the kernel stack of the thread using ptrace(PT_LWPINFO) call can be observed in userspace.
A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys.
Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

If the chan_skinny (AKA SCCP protocol) channel driver is flooded with certain requests it can cause the asterisk process to use excessive amounts of virtual memory eventually causing asterisk to stop processing requests of any kind.
Exim developers team reports:
The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to cause a denial of service (infinite loop and stack exhaustion) via vectors involving BDAT commands and an improper check for a '.' character signifying the end of the content, related to the bdat_getc function.

- NTLM buffer overflow via integer overflow (CVE-2017-8816)
libcurl contains a buffer overrun flaw in the NTLM authentication code. The internal function Curl_ntlm_core_mk_ntlmv2_hash sums up the lengths of the user name + password (= SUM) and multiplies the sum by two (= SIZE) to figure out how large storage to allocate from the heap.- FTP wildcard out of bounds read (CVE-2017-8817)
libcurl contains a read out of bounds flaw in the FTP wildcard function. libcurl's FTP wildcard matching feature, which is enabled with the CURLOPT_WILDCARDMATCH option can use a built-in wildcard function or a user provided one. The built-in wildcard function has a flaw that makes it not detect the end of the pattern string if it ends with an open bracket ([) but instead it will continue reading the heap beyond the end of the URL buffer that holds the wildcard.- SSL out of buffer access (CVE-2017-8818)
libcurl contains an out boundary access flaw in SSL related code. When allocating memory for a connection (the internal struct called connectdata), a certain amount of memory is allocated at the end of the struct to be used for SSL related structs. Those structs are used by the particular SSL library libcurl is built to use. The application can also tell libcurl which specific SSL library to use if it was built to support more than one.

The Internet2 community reports:
The Shibboleth Service Provider software includes a MetadataProvider plugin with the plugin type "Dynamic" to obtain metadata on demand from a query server, in place of the more typical mode of downloading aggregates separately containing all of the metadata to load.
All the plugin types rely on MetadataFilter plugins to perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments.
Due to a coding error, the "Dynamic" plugin fails to configure itself with the filters provided to it and thus omits whatever checks they are intended to perform, which will typically leave deployments vulnerable to active attacks involving the substitution of metadata if the network path to the query service is compromised.

Jenkins developers report:
Jenkins stores metadata related to people, which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping. This potentially resulted in a number of problems.
Autocompletion suggestions for text fields were not escaped, resulting in a persisted cross-site scripting vulnerability if the source for the suggestions allowed specifying text that includes HTML metacharacters like less-than and greater-than characters.
The Asterisk project reports:
A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. This then leads to file descriptors and RTP ports being leaked as well.
The Asterisk project reports:
No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. The earlier AST-2017-001 advisory for the CDR user field overflow was for the Party A buffer.
The Asterisk project reports:
By carefully crafting invalid values in the Cseq and the Via header port, pjprojects packet parsing code can create strings larger than the buffer allocated to hold them. This will usually cause Asterisk to crash immediately. The packets do not have to be authenticated.

Node.js reports:
Node.js was susceptible to a remote DoS attack due to a change that came in as part of zlib v1.2.9. In zlib v1.2.9 8 became an invalid value for the windowBits parameter and Node's zlib module will crash or throw an exception (depending on the version)
GitLab reports:
Cross-Site Scripting (XSS) vulnerability in the Markdown sanitization filter
Yasin Soliman via HackerOne reported a Cross-Site Scripting (XSS) vulnerability in the GitLab markdown sanitization filter. The sanitization filter was not properly stripping invalid characters from URL schemes and was therefore vulnerable to persistent XSS attacks anywhere Markdown was supported.
Cross-Site Scripting (XSS) vulnerability in search bar
Josh Unger reported a Cross-Site Scripting (XSS) vulnerability in the issue search bar. Usernames were not being properly HTML escaped inside the author filter would could allow arbitrary script execution.
Open redirect in repository git redirects
Eric Rafaloff via HackerOne reported that GitLab was vulnerable to an open redirect vulnerability when redirecting requests for repository names that include the git extension. GitLab was not properly removing dangerous parameters from the params field before redirecting which could allow an attacker to redirect users to arbitrary hosts.
Username changes could leave repositories behind
An internal code review discovered that a bug in the code that moves repositories during a username change could potentially leave behind projects, allowing an attacker who knows the previous username to potentially steal the contents of repositories on instances that are not configured with hashed namespaces.
The Apache Openofffice project reports:
CVE-2017-3157: Arbitrary file disclosure in Calc and Writer
By exploiting the way OpenOffice renders embedded objects, an attacker could craft a document that allows reading in a file from the user's filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to sent the document back to the attacker.
The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back.
CVE-2017-9806: Out-of-Bounds Write in Writer's WW8Fonts Constructor
A vulnerability in the OpenOffice Writer DOC file parser, and specifically in the WW8Fonts Constructor, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
CVE-2017-12607: Out-of-Bounds Write in Impress' PPT Filter
A vulnerability in OpenOffice's PPT file parser, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
CVE-2017-12608: Out-of-Bounds Write in Writer's ImportOldFormatStyles
A vulnerability in OpenOffice Writer DOC file parser, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
The cURL project reports:
libcurl contains a buffer overrun flaw in the IMAP handler.
An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function.
libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded.
Frederik Deweerdt reports:
Multiple Denial-of-Service vulnerabilities exist in h2o workers - see references for full details.
CVE-2017-10868: Worker processes may crash when receiving a request with invalid framing.
CVE-2017-10869: The stack may overflow when proxying huge requests.
Irssi reports:
When installing themes with unterminated colour formatting sequences, Irssi may access data beyond the end of the string.
While waiting for the channel synchronisation, Irssi may incorrectly fail to remove destroyed channels from the query list, resulting in use after free conditions when updating the state later on.
Certain incorrectly formatted DCC CTCP messages could cause NULL pointer dereference.
Overlong nicks or targets may result in a NULL pointer dereference while splitting the message.
In certain cases Irssi may fail to verify that a Safe channel ID is long enough, causing reads beyond the end of the string.

MIT reports:
CVE-2017-11368:
In MIT krb5 1.7 and later, an authenticated attacker can cause an assertion failure in krb5kdc by sending an invalid S4U2Self or S4U2Proxy request.
CVE-2017-11462:
RFC 2744 permits a GSS-API implementation to delete an existing security context on a second or subsequent call to gss_init_sec_context() or gss_accept_sec_context() if the call results in an error. This API behavior has been found to be dangerous, leading to the possibility of memory errors in some callers. For safety, GSS-API implementations should instead preserve existing security contexts on error until the caller deletes them.
All versions of MIT krb5 prior to this change may delete acceptor contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through 1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on error.

Solr developers report:
Lucene XML parser does not explicitly prohibit doctype declaration and expansion of external entities which leads to arbitrary HTTP requests to the local SOLR instance and to bypass all firewall restrictions.
Solr "RunExecutableListener" class can be used to execute arbitrary commands on specific events, for example after each update query. The problem is that such listener can be enabled with any parameters just by using Config API with add-listener command.
jenkins developers report:
A total of 11 issues are reported, please see reference URL for details.
The Xen project reports multiple vulnerabilities.
Mozilla reports:
During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash.
osip developers reports:
In libosip2 in GNU oSIP 4.1.0 and 5.0.0, a malformed SIP message can lead to a heap buffer overflow in the msg_osip_body_parse() function defined in osipparser2/osip_message_parse.c, resulting in a remote DoS.

tomcat developers reports:
When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.
The cURL project reports:
FTP PWD response parser out of bounds read
libcurl may read outside of a heap allocated buffer when doing FTP.
When libcurl connects to an FTP server and successfully logs in (anonymous or not), it asks the server for the current directory with the PWD command. The server then responds with a 257 response containing the path, inside double quotes. The returned path name is then kept by libcurl for subsequent uses.
Due to a flaw in the string parser for this directory name, a directory name passed like this but without a closing double quote would lead to libcurl not adding a trailing NUL byte to the buffer holding the name. When libcurl would then later access the string, it could read beyond the allocated heap buffer and crash or wrongly access data beyond the buffer, thinking it was part of the path.
A malicious server could abuse this fact and effectively prevent libcurl-based clients to work with it - the PWD command is always issued on new FTP connections and the mistake has a high chance of causing a segfault.
There is no limit on the password length.
A remote attacker may be able to cause an affected SSH server to use excessive amount of CPU by sending very long passwords, when PasswordAuthentication is enabled by the system administrator.
There is a programming error in the Heimdal implementation that used an unauthenticated, plain-text version of the KDC-REP service name found in a ticket.
An attacker who has control of the network between a client and the service it talks to will be able to impersonate the service, allowing a successful man-in-the-middle (MITM) attack that circumvents the mutual authentication.

sam2p developers report:
In sam2p 0.49.3, a heap-based buffer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp.
In sam2p 0.49.3, the in_xpm_reader function in in_xpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array element.
In sam2p 0.49.3, an integer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp, leading to an invalid write operation.
In sam2p 0.49.3, the pcxLoadRaster function in in_pcx.cpp has an integer signedness error leading to a heap-based buffer overflow.
Because of an integer overflow in sam2p 0.49.3, a loop executes 0xffffffff times, ending with an invalid read of size 1 in the Image::Indexed::sortPal function in image.cpp. However, this also causes memory corruption because of an attempted write to the invalid d[0xfffffffe] array element.
In sam2p 0.49.3, there is an invalid read of size 2 in the parse_rgb function in in_xpm.cpp. However, this can also cause a write to an illegal address.
libraw developers report:
In LibRaw through 0.18.4, an out of bounds read flaw related to kodak_65000_load_raw has been reported in dcraw/dcraw.c and internal/dcraw_common.cpp. An attacker could possibly exploit this flaw to disclose potentially sensitive memory or cause an application crash.
Steffan Karger reports:
The bounds check in read_key() was performed after using the value, instead of before. If 'key-method 1' is used, this allowed an attacker to send a malformed packet to trigger a stack buffer overflow. [...]
Note that 'key-method 1' has been replaced by 'key method 2' as the default in OpenVPN 2.0 (released on 2005-04-17), and explicitly deprecated in 2.4 and marked for removal in 2.5. This should limit the amount of users impacted by this issue.

The Asterisk project reports:
This is a follow up advisory to AST-2017-005.
Insufficient RTCP packet validation could allow reading stale buffer contents and when combined with the "nat" and "symmetric_rtp" options allow redirecting where Asterisk sends the next RTCP report.
The RTP stream qualification to learn the source address of media always accepted the first RTP packet as the new source and allowed what AST-2017-005 was mitigating. The intent was to qualify a series of packets before accepting the new source address.
The RTP/RTCP stack will now validate RTCP packets before processing them.

CVE-2017-0898: Buffer underrun vulnerability in Kernel.sprintf
If a malicious format string which contains a precious specifier (*) is passed and a huge minus value is also passed to the specifier, buffer underrun may be caused. In such situation, the result may contains heap, or the Ruby interpreter may crash.
CVE-2017-10784: Escape sequence injection vulnerability in the Basic authentication of WEBrick
When using the Basic authentication of WEBrick, clients can pass an arbitrary string as the user name. WEBrick outputs the passed user name intact to its log, then an attacker can inject malicious escape sequences to the log and dangerous control characters may be executed on a victim’s terminal emulator.
This vulnerability is similar to a vulnerability already fixed, but it had not been fixed in the Basic authentication.
CVE-2017-14033: Buffer underrun vulnerability in OpenSSL ASN1 decode
If a malicious string is passed to the decode method of OpenSSL::ASN1, buffer underrun may be caused and the Ruby interpreter may crash.
CVE-2017-14064: Heap exposure vulnerability in generating JSON
The generate method of JSON module optionally accepts an instance of JSON::Ext::Generator::State class. If a malicious instance is passed, the result may include contents of heap.
Gem in a box XSS vulenrability - CVE-2017-14506:
Malicious attacker create GEM file with crafted homepage value (gem.homepage in .gemspec file) includes XSS payload.
The attacker access geminabox system and uploads the gem file (or uses CSRF/SSRF attack to do so).
From now on, any user access Geminabox web server, executes the malicious XSS payload, that will delete any gems on the server, and won't let users use the geminabox anymore. (make victim's browser crash or redirect them to other hosts).
The Fuzzing Project reports:
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.

A carefully crafted URI in a From, To or Contact header could cause Asterisk to crash.
The Asterisk project reports:
AST-2017-005 - A change was made to the strict RTP support in the RTP stack to better tolerate late media when a reinvite occurs. When combined with the symmetric RTP support this introduced an avenue where media could be hijacked. Instead of only learning a new address when expected the new code allowed a new source address to be learned at all times.
AST-2017-006 - The app_minivm module has an "externnotify" program configuration option that is executed by the MinivmNotify dialplan application. The application uses the caller-id name and number as part of a built string passed to the OS shell for interpretation and execution. Since the caller-id name and number can come from an untrusted source, a crafted caller-id name or number allows an arbitrary shell command injection.

mnaberez reports:
supervisord can be configured to run an HTTP server on a TCP socket and/or a Unix domain socket. The HTTP server is how supervisorctl communicates with supervisord. If an HTTP server has been enabled, it will always serve both HTML pages and an XML-RPC interface. A vulnerability has been found where an authenticated client can send a malicious XML-RPC request to supervisord that will run arbitrary shell commands on the server. The commands will be run as the same user as supervisord. Depending on how supervisord has been configured, this may be root.
This vulnerability can only be exploited by an authenticated client or if supervisord has been configured to run an HTTP server without authentication. If authentication has not been enabled, supervisord will log a message at the critical level every time it starts.

Mercurial Release Notes:
CVE-2017-1000115
Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository.
CVE-2017-1000116
Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed.
subversion team reports:
A Subversion client sometimes connects to URLs provided by the repository. This happens in two primary cases: during 'checkout', 'export', 'update', and 'switch', when the tree being downloaded contains svn:externals properties; and when using 'svnsync sync' with one URL argument.
A maliciously constructed svn+ssh:// URL would cause Subversion clients to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server.
The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.
An exploit has been tested.
GitLab reports:
Remote Command Execution in git client
An external code review performed by Recurity-Labs identified a remote command execution vulnerability in git that could be exploited via the "Repo by URL" import option in GitLab. The command line git client was not properly escaping command line arguments in URLs using the SSH protocol before invoking the SSH client. A specially crafted URL could be used to execute arbitrary shell commands on the GitLab server.
To fully patch this vulnerability two fixes were needed. The Omnibus versions of GitLab contain a patched git client. For source users who may still be running an older version of git, GitLab now also blocks import URLs containing invalid host and usernames.
This issue has been assigned CVE-2017-12426.Improper sanitization of GitLab export files on import
GitLab versions 8.13.3, 8.12.8, 8.11.10, 8.10.13, and 8.9.12 contained a patch for a critical directory traversal vulnerability in the GitLab export feature that could be exploited by including symlinks in the export file and then re-importing it to a GitLab instance. This vulnerability was patched by checking for and removing symlinks in these files on import.
Recurity-Labs also determined that this fix did not properly remove symlinks for hidden files. Though not as dangerous as the original vulnerability hidden file symlinks could still be used to steal copies of git repositories belonging to other users if the path to the git repository was known by the attacker. An updated fix has been included in these releases that properly removes all symlinks.
This import option was not made available to non-admin users until GitLab 8.13.0.

The samba project reports:
A MITM attacker may impersonate a trusted server and thus gain elevated access to the domain by returning malicious replication or authorization data.
Updates are now available for all active Node.js release lines as well as the 7.x line. These include the fix for the high severity vulnerability identified in the initial announcement, one additional lower priority Node.js vulnerability in the 4.x release line, as well as some lower priority fixes for Node.js dependencies across the current release lines.
Constant Hashtable Seeds (CVE pending)
Node.js was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup. Thanks to Jann Horn of Google Project Zero for reporting this vulnerability.
This is a high severity vulnerability and applies to all active release lines (4.x, 6.x, 8.x) as well as the 7.x line.
http.get with numeric authorization options creates uninitialized buffers
Application code that allows the auth field of the options object used with http.get() to be set to a number can result in an uninitialized buffer being created/used as the authentication string.
This is a low severity defect and only applies to the 4.x release line.

the PHP project reports:
- A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer (CVE-2017-9224).
- A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption (CVE-2017-9226).
- A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching. Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer (CVE-2017-9227).
- A heap out-of-bounds write occurs in bitset_set_range() during regular expression compilation due to an uninitialized variable from an incorrect state transition. An incorrect state transition in parse_char_class() could create an execution path that leaves a critical local variable uninitialized until it's used as an index, resulting in an out-of-bounds write memory corruption (CVE-2017-9228).
- A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition (CVE-2017-9228).

ipfilter(4), capable of stateful packet inspection, using the "keep state" or "keep frags" rule options, will not only maintain the state of connections, such as TCP streams or UDP communication, it also maintains the state of fragmented packets. When a packet fragments are received they are cached in a hash table (and linked list). When a fragment is received it is compared with fragments already cached in the hash table for a match. If it does not match the new entry is used to create a new entry in the hash table. If on the other hand it does match, unfortunately the wrong entry is freed, the entry in the hash table. This results in use after free panic (and for a brief moment prior to the panic a memory leak due to the wrong entry being freed).
Carefully feeding fragments that are allowed to pass by an ipfilter(4) firewall can be used to cause a panic followed by reboot loop denial of service attack.

The Asterisk project reports:
A remote memory exhaustion can be triggered by sending an SCCP packet to Asterisk system with "chan_skinny" enabled that is larger than the length of the SCCP header but smaller than the packet length specified in the header. The loop that reads the rest of the packet doesn't detect that the call to read() returned end-of-file before the expected number of bytes and continues infinitely. The "partial data" message logging in that tight loop causes Asterisk to exhaust all available memory.
The Asterisk project reports:
A remote crash can be triggered by sending a SIP packet to Asterisk with a specially crafted CSeq header and a Via header with no branch parameter. The issue is that the PJSIP RFC 2543 transaction key generation algorithm does not allocate a large enough buffer. By overrunning the buffer, the memory allocation table becomes corrupted, leading to an eventual crash.
The multi-part body parser in PJSIP contains a logical error that can make certain multi-part body parts attempt to read memory from outside the allowed boundaries. A specially-crafted packet can trigger these invalid reads and potentially induce a crash.
This issues is in PJSIP, and so the issue can be fixed without performing an upgrade of Asterisk at all. However, we are releasing a new version of Asterisk with the bundled PJProject updated to include the fix.
If you are running Asterisk with chan_sip, this issue does not affect you.

Information Disclosure in Issue and Merge Request Trackers
During an internal code review a critical vulnerability in the GitLab Issue and Merge Request trackers was discovered. This vulnerability could allow a user with access to assign ownership of an issue or merge request to another user to disclose that user's private token, email token, email address, and encrypted OTP secret. Reporter-level access to a GitLab project is required to exploit this flaw.
SSRF when importing a project from a Repo by URL
GitLab instances that have enabled project imports using "Repo by URL" were vulnerable to Server-Side Request Forgery attacks. By specifying a project import URL of localhost an attacker could target services that are bound to the local interface of the server. These services often do not require authentication. Depending on the service an attacker might be able craft an attack using the project import request URL.
Links in Environments tab vulnerable to tabnabbing
edio via HackerOne reported that user-configured Environment links include target=_blank but do not also include rel: noopener noreferrer. Anyone clicking on these links may therefore be subjected to tabnabbing attacks where a link back to the requesting page is maintained and can be manipulated by the target server.

Samuli Seppänen reports:
OpenVPN v2.4.0 was audited for security vulnerabilities independently by Quarkslabs (funded by OSTIF) and Cryptography Engineering (funded by Private Internet Access) between December 2016 and April 2017. The primary findings were two remote denial-of-service vulnerabilities. Fixes to them have been backported to v2.3.15.
An authenticated client can do the 'three way handshake' (P_HARD_RESET, P_HARD_RESET, P_CONTROL), where the P_CONTROL packet is the first that is allowed to carry payload. If that payload is too big, the OpenVPN server process will stop running due to an ASSERT() exception. That is also the reason why servers using tls-auth/tls-crypt are protected against this attack - the P_CONTROL packet is only accepted if it contains the session ID we specified, with a valid HMAC (challenge-response). (CVE-2017-7478)
An authenticated client can cause the server's the packet-id counter to roll over, which would lead the server process to hit an ASSERT() and stop running. To make the server hit the ASSERT(), the client must first cause the server to send it 2^32 packets (at least 196 GB).

cURL security advisory:
libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which was established by the previous certificate (or no certificate).
libcurl supports by default the use of TLS session id/ticket to resume previous TLS sessions to speed up subsequent TLS handshakes. They are used when for any reason an existing TLS connection couldn't be kept alive to make the next handshake faster.
This flaw is a regression and identical to CVE-2016-5419 reported on August 3rd 2016, but affecting a different version range.

ISC reports:
A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate.
An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met.
Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order.
named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc.
A regression introduced in a recent feature change has created a situation under which some versions of named can be caused to exit with a REQUIRE assertion failure if they are sent a null command string.

The phpMyAdmin team reports:
Summary
Bypass $cfg['Servers'][$i]['AllowNoPassword']
Description
A vulnerability was discovered where the restrictions caused by $cfg['Servers'][$i]['AllowNoPassword'] = false are bypassed under certain PHP versions. This can allow the login of users who have no password set even if the administrator has set $cfg['Servers'][$i]['AllowNoPassword'] to false (which is also the default).
This behavior depends on the PHP version used (it seems PHP 5 is affected, while PHP 7.0 is not).
Severity
We consider this vulnerability to be of moderate severity.
Mitigation factor
Set a password for all users.

CVE-2017-6379: Some admin paths were not protected with a CSRF token
CVE-2017-6381: Remote code execution
Simon G. Tatham reports:
Many versions of PuTTY prior to 0.68 have a heap-corrupting integer overflow bug in the ssh_agent_channel_data function which processes messages sent by remote SSH clients to a forwarded agent connection. [...]
This bug is only exploitable at all if you have enabled SSH agent forwarding, which is turned off by default. Moreover, an attacker able to exploit this bug would have to have already be able to connect to the Unix-domain socket representing the forwarded agent connection. Since any attacker with that capability would necessarily already be able to generate signatures with your agent's stored private keys, you should in normal circumstances be defended against this vulnerability by the same precautions you and your operating system were already taking to prevent untrusted people from accessing your SSH agent.

Janos Follath reports:
- If a malicious peer supplies a certificate with a specially crafted secp224k1 public key, then an attacker can cause the server or client to attempt to free block of memory held on stack. Depending on the platform, this could result in a Denial of Service (client crash) or potentially could be exploited to allow remote code execution with the same privileges as the host application.
- If the client and the server both support MD5 and the client can be tricked to authenticate to a malicious server, then the malicious server can impersonate the client. To launch this man in the middle attack, the adversary has to compute a chosen-prefix MD5 collision in real time. This is very expensive computationally, but can be practical. Depending on the platform, this could result in a Denial of Service (client crash) or potentially could be exploited to allow remote code execution with the same privileges as the host application.
- A bug in the logic of the parsing of a PEM encoded Certificate Revocation List in mbedtls_x509_crl_parse() can result in an infinite loop. In versions before 1.3.10 the same bug results in an infinite recursion stack overflow that usually crashes the application. Methods and means of acquiring the CRLs is not part of the TLS handshake and in the strict TLS setting this vulnerability cannot be triggered remotely. The vulnerability cannot be triggered unless the application explicitly calls mbedtls_x509_crl_parse() or mbedtls_x509_crl_parse_file()on a PEM formatted CRL of untrusted origin. In which case the vulnerability can be exploited to launch a denial of service attack against the application.

Albert Aastals Cid reports:
A directory traversal issue was found in KTNEF which can be exploited by tricking a user into opening a malicious winmail.dat file. The issue allows to write files with the permission of the user opening the winmail.dat file during extraction.
Albert Astals Cid reports:
Using a malicious PAC file, and then using exfiltration methods in the PAC function FindProxyForURL() enables the attacker to expose full https URLs.
This is a security issue since https URLs may contain sensitive information in the URL authentication part (user:password@host), and in the path and the query (e.g. access tokens).
This attack can be carried out remotely (over the LAN) since proxy settings allow "Detect Proxy Configuration Automatically". This setting uses WPAD to retrieve the PAC file, and an attacker who has access to the victim's LAN can interfere with the WPAD protocols (DHCP/DNS+HTTP) and inject his/her own malicious PAC instead of the legitimate one.
WordPress versions 4.7.2 and earlier are affected by six security issues.

ikiwiki reports:
The ikiwiki maintainers discovered further flaws similar to CVE-2016-9646 in the passwordauth plugin's use of CGI::FormBuilder, with a more serious impact:
An attacker who can log in to a site with a password can log in as a different and potentially more privileged user.
An attacker who can create a new account can set arbitrary fields in the user database for that account
Mitre reports:
ikiwiki 3.20161219 does not properly check if a revision changes the access permissions for a page on sites with the git and recentchanges plugins and the CGI interface enabled, which allows remote attackers to revert certain changes by leveraging permissions to change the page before the revision was made.
When CGI::FormBuilder->field("foo") is called in list context (and in particular in the arguments to a subroutine that takes named arguments), it can return zero or more values for foo from the CGI request, rather than the expected single value. This breaks the usual Perl parsing convention for named arguments, similar to CVE-2014-1572 in Bugzilla (which was caused by a similar API design issue in CGI.pm).

The cURL project reports:
SSL_VERIFYSTATUS ignored
curl and libcurl support "OCSP stapling", also known as the TLS Certificate Status Request extension (using the CURLOPT_SSL_VERIFYSTATUS option). When telling curl to use this feature, it uses that TLS extension to ask for a fresh proof of the server's certificate's validity. If the server doesn't support the extension, or fails to provide said proof, curl is expected to return an error.
Due to a coding mistake, the code that checks for a test success or failure, ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. Contrary to how it used to function and contrary to how this feature is documented to work.
This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality.
The Xen Project reports:

The Apache Groovy project reports:
When an application with Groovy on classpath uses standard Java serialization mechanisms, e.g. to communicate between servers or to store local data, it is possible for an attacker to bake a special serialized object that will execute code directly when deserialized. All applications which rely on serialization and do not isolate the code which deserializes objects are subject to this vulnerability. This is similar to CVE-2015-3253 but this exploit involves extra wrapping of objects and catching of exceptions which are now safe guarded against.

ISC reports:
A malformed query response received by a recursive server in response to a query of RTYPE ANY could trigger an assertion failure while named is attempting to add the RRs in the query response to the cache.
Depending on the type of query and the EDNS options in the query they receive, DNSSEC-enabled authoritative servers are expected to include RRSIG and other RRsets in their responses to recursive servers. DNSSEC-validating servers will also make specific queries for DS and other RRsets. Whether DNSSEC-validating or not, an error in processing malformed query responses that contain DNSSEC-related RRsets that are inconsistent with other RRsets in the same query response can trigger an assertion failure. Although the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer.
An unusually-formed answer containing a DS resource record could trigger an assertion failure. While the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer having the required properties.
An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes.
The ssh-agent(1) agent supports loading a PKCS#11 module from outside a trusted whitelist. An attacker can request loading of a PKCS#11 module across forwarded agent-socket. [CVE-2016-10009]
When privilege separation is disabled, forwarded Unix domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. [CVE-2016-10010]
A remote attacker who have control of a forwarded agent-socket on a remote system and have the ability to write files on the system running ssh-agent(1) agent can run arbitrary code under the same user credential. Because the attacker must already have some control on both systems, it is relatively hard to exploit this vulnerability in a practical attack. [CVE-2016-10009]
When privilege separation is disabled (on FreeBSD, privilege separation is enabled by default and has to be explicitly disabled), an authenticated attacker can potentially gain root privileges on systems running OpenSSH server. [CVE-2016-10010]
Cesar Pereida Garcia reports:
The signing function in crypto/ecdsa/ecdsa_ossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect omits setting the BN_FLG_CONSTTIME flag for nonces, failing to take a secure code path in the BN_mod_inverse method and therefore resulting in a cache-timing attack vulnerability.
A malicious user with local access can recover ECDSA P-256 private keys.

Legal Hackers reports:
An independent research uncovered a critical vulnerability in PHPMailer that could potentially be used by (unauthenticated) remote attackers to achieve remote arbitrary code execution in the context of the web server user and remotely compromise the target web application.
To exploit the vulnerability an attacker could target common website components such as contact/feedback forms, registration forms, password email resets and others that send out emails with the help of a vulnerable version of the PHPMailer class.
The first patch of the vulnerability CVE-2016-10033 was incomplete. This advisory demonstrates the bypass of the patch. The bypass allows to carry out Remote Code Execution on all current versions (including 5.2.19).
Samba team reports:
[CVE-2016-2123] Authenticated users can supply malicious dnsRecord attributes on DNS objects and trigger a controlled memory corruption.
[CVE-2016-2125] Samba client code always requests a forwardable ticket when using Kerberos authentication. This means the target server, which must be in the current or trusted domain/realm, is given a valid general purpose Kerberos "Ticket Granting Ticket" (TGT), which can be used to fully impersonate the authenticated user or service.
[CVE-2016-2126] A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket due to incorrect handling of the PAC checksum. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions.
Matthew Garett reports:
Reported this to upstream 8 months ago without response, so: libupnp's default behaviour allows anyone to write to your filesystem. Seriously. Find a device running a libupnp based server (Shodan says there's rather a lot), and POST a file to /testfile. Then GET /testfile ... and yeah if the server is running as root (it is) and is using / as the web root (probably not, but maybe) this gives full host fs access.

Project curl Security Advisory:
libcurl's (new) internal function that returns a good 32bit random value was implemented poorly and overwrote the pointer instead of writing the value into the buffer the pointer pointed to.
This random value is used to generate nonces for Digest and NTLM authentication, for generating boundary strings in HTTP formposts and more. Having a weak or virtually non-existent random there makes these operations vulnerable.
This function is brand new in 7.52.0 and is the result of an overhaul to make sure libcurl uses strong random as much as possible - provided by the backend TLS crypto libraries when present. The faulty function was introduced in this commit.
We are not aware of any exploit of this flaw.
Squid security advisory 2016:10 reports:
Due to incorrect comparison of request headers Squid can deliver responses containing private data to clients it should not have reached.
This problem allows a remote attacker to discover private and sensitive information about another clients browsing session. Potentially including credentials which allow access to further sensitive resources. This problem only affects Squid configured to use the Collapsed Forwarding feature. It is of particular importance for HTTPS reverse-proxy sites with Collapsed Forwarding.

CVE-2016-7433: Reboot sync calculation problem. Reported independently by Brian Utterback of Oracle, and by Sharon Goldberg and Aanchal Malhotra of Boston University.
A remote attacker who can send a specially crafted packet to cause a NULL pointer dereference that will crash ntpd, resulting in a Denial of Service. [CVE-2016-9311]
An exploitable configuration modification vulnerability exists in the control mode (mode 6) functionality of ntpd. If, against long-standing BCP recommendations, "restrict default noquery ..." is not specified, a specially crafted control mode packet can set ntpd traps, providing information disclosure and DDoS amplification, and unset ntpd traps, disabling legitimate monitoring by an attacker from remote. [CVE-2016-9310]
An attacker with access to the NTP broadcast domain can periodically inject specially crafted broadcast mode NTP packets into the broadcast domain which, while being logged by ntpd, can cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. [CVE-2016-7427]
An attacker with access to the NTP broadcast domain can send specially crafted broadcast mode NTP packets to the broadcast domain which, while being logged by ntpd, will cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. [CVE-2016-7428]
Origin timestamp problems were fixed in ntp 4.2.8p6. However, subsequent timestamp validation checks introduced a regression in the handling of some Zero origin timestamp checks. [CVE-2016-7431]
If ntpd is configured to allow mrulist query requests from a server that sends a crafted malicious packet, ntpd will crash on receipt of that crafted malicious mrulist query packet. [CVE-2016-7434]
An attacker who knows the sources (e.g., from an IPv4 refid in server response) and knows the system is (mis)configured in this way can periodically send packets with spoofed source address to keep the rate limiting activated and prevent ntpd from accepting valid responses from its sources. [CVE-2016-7426]
Ntp Bug 2085 described a condition where the root delay was included twice, causing the jitter value to be higher than expected. Due to a misinterpretation of a small-print variable in The Book, the fix for this problem was incorrect, resulting in a root distance that did not include the peer dispersion. The calculations and formulas have been reviewed and reconciled, and the code has been updated accordingly. [CVE-2016-7433]

The Joomla Security Strike team has been following up on the critical security vulnerability patched last week. Since the recent update it has become clear that the root cause is a bug in PHP itself. This was fixed by PHP in September of 2015 with the releases of PHP 5.4.45, 5.5.29, 5.6.13 (Note that this is fixed in all versions of PHP 7 and has been back-ported in some specific Linux LTS versions of PHP 5.3). This fixes the bug across all supported PHP versions.
[20151207] - Core - SQL Injection
Inadequate filtering of request data leads to a SQL Injection vulnerability.
The Xen Project reports:
Certain PV guest kernel operations (page table writes in particular) need emulation, and use Xen's general x86 instruction emulator. This allows a malicious guest kernel which asynchronously modifies its instruction stream to effect the clearing of EFLAGS.IF from the state used to return to guest context.
A malicious guest kernel administrator can cause a host hang or crash, resulting in a Denial of Service.
Apache Software Foundation reports:
Please reference CVE/URL list for details
The Xen Project reports:
The typical behaviour of singlestepping exceptions is determined at the start of the instruction, with a #DB trap being raised at the end of the instruction. SYSCALL (and SYSRET, although we don't implement it) behave differently because the typical behaviour allows userspace to escalate its privilege. (This difference in behaviour seems to be undocumented.) Xen wrongly raised the exception based on the flags at the start of the instruction.
Guest userspace which can invoke the instruction emulator can use this flaw to escalate its privilege to that of the guest kernel.

WordPress versions 4.6 and earlier are affected by two security issues: a cross-site scripting vulnerability via image filename, reported by SumOfPwn researcher Cengiz Han Sahin; and a path traversal vulnerability in the upgrade package uploader, reported by Dominik Schilling from the WordPress security team.
The Xen Project reports:
The x86 instruction CMPXCHG8B is supposed to ignore legacy operand size overrides; it only honors the REX.W override (making it CMPXCHG16B). So, the operand size is always 8 or 16. When support for CMPXCHG16B emulation was added to the instruction emulator, this restriction on the set of possible operand sizes was relied on in some parts of the emulation; but a wrong, fully general, operand size value was used for other parts of the emulation. As a result, if a guest uses a supposedly-ignored operand size prefix, a small amount of hypervisor stack data is leaked to the guests: a 96 bit leak to guests running in 64-bit mode; or, a 32 bit leak to other guests.
A malicious unprivileged guest may be able to obtain sensitive information from the host.
The PHP project reports:
This is a security release. Several security bugs were fixed in this release.
The Asterisk project reports:
The chan_sip channel driver has a liberal definition for whitespace when attempting to strip the content between a SIP header name and a colon character. Rather than following RFC 3261 and stripping only spaces and horizontal tabs, Asterisk treats any non-printable ASCII character as if it were whitespace.
This mostly does not pose a problem until Asterisk is placed in tandem with an authenticating SIP proxy. In such a case, a crafty combination of valid and invalid To headers can cause a proxy to allow an INVITE request into Asterisk without authentication since it believes the request is an in-dialog request. However, because of the bug described above, the request will look like an out-of-dialog request to Asterisk. Asterisk will then process the request as a new call. The result is that Asterisk can process calls from unvetted sources without any authentication.
If you do not use a proxy for authentication, then this issue does not affect you.
If your proxy is dialog-aware (meaning that the proxy keeps track of what dialogs are currently valid), then this issue does not affect you.
If you use chan_pjsip instead of chan_sip, then this issue does not affect you.
The Asterisk project reports:
If an SDP offer or answer is received with the Opus codec and with the format parameters separated using a space the code responsible for parsing will recursively call itself until it crashes. This occurs as the code does not properly handle spaces separating the parameters. This does NOT require the endpoint to have Opus configured in Asterisk. This also does not require the endpoint to be authenticated. If guest is enabled for chan_sip or anonymous in chan_pjsip an SDP offer or answer is still processed and the crash occurs.
Multiple sources report:
CVE-2015-2141: The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack. Fixed in 5.6.3.
CVE-2016-3995: Incorrect implementation of Rijndael timing attack countermeasure. Fixed in 5.6.4.
CVE-2016-7420: Library built without -DNDEBUG could egress sensitive information to the filesystem via a core dump if an assert was triggered. Fixed in 5.6.5.
The bounds checking of accesses to guest memory greater than 4GB by device emulations is subject to integer overflow.
For a bhyve virtual machine with more than 3GB of guest memory configured, a malicious guest could craft device descriptors that could give it access to the heap of the bhyve process. Since the bhyve process is running as root, this may allow guests to obtain full control of the hosts they're running on.
A specially crafted argument can trigger a static buffer overflow in the library, with possibility to rewrite following static buffers that belong to other library functions.
Due to very limited use of the function in the existing applications, and limited length of the overflow, exploitation of the vulnerability does not seem feasible. None of the utilities and daemons in the base system are known to be vulnerable. However, careful review of third party software that may use the function was not performed.
An unexpected sequence of memory allocation failures combined with insufficient error checking could result in the construction and execution of an argument sequence that was not intended.
An attacker who controls the sequence of memory allocation failures and success may cause login(1) to run without authentication and may be able to cause misbehavior of login(1) replacements.
No practical way of controlling these memory allocation failures is known at this time.
mod_http2 reports:
The Apache HTTPD web server (from 2.4.17-2.4.23) did not apply limitations on request headers correctly when experimental module for the HTTP/2 protocol is used to access a resource.
The net result is that a the server allocates too much memory instead of denying the request. This can lead to memory exhaustion of the server by a properly crafted request.

Daniel P. Berrange reports:
The VNC server websockets decoder will read and buffer data from websockets clients until it sees the end of the HTTP headers, as indicated by \r\n\r\n. In theory this allows a malicious to trick QEMU into consuming an arbitrary amount of RAM.
The Xen Project reports:
pygrub, the boot loader emulator, fails to quote (or sanity check) its results when reporting them to its caller.
A malicious guest administrator can obtain the contents of sensitive host files (an information leak). Additionally, a malicious guest administrator can cause files on the host to be removed, causing a denial of service. In some unusual host configurations, ability to remove certain files may be usable for privilege escalation.
The Xen Project reports:
The compiler can emit optimizations in qemu which can lead to double fetch vulnerabilities. Specifically data on the rings shared between qemu and the hypervisor (which the guest under control can obtain mappings of) can be fetched twice (during which time the guest can alter the contents) possibly leading to arbitrary code execution in qemu.
Malicious administrators can exploit this vulnerability to take over the qemu process, elevating its privilege to that of the qemu process.
In a system not using a device model stub domain (or other techniques for deprivileging qemu), malicious guest administrators can thus elevate their privilege to that of the host.
The Xen Project reports:
The x86 instructions BT, BTC, BTR, and BTS, when used with a destination memory operand and a source register rather than an immediate operand, access a memory location offset from that specified by the memory operand as specified by the high bits of the register source.
A malicious guest can modify arbitrary memory, allowing for arbitrary code execution (and therefore privilege escalation affecting the whole host), a crash of the host (leading to a DoS), or information leaks. The vulnerability is sometimes exploitable by unprivileged guest user processes.
The Xen Project reports:
Along with their main kernel binary, unprivileged guests may arrange to have their Xen environment load (kernel) symbol tables for their use. The ELF image metadata created for this purpose has a few unused bytes when the symbol table binary is in 32-bit ELF format. These unused bytes were not properly cleared during symbol table loading.
A malicious unprivileged guest may be able to obtain sensitive information from the host.
The information leak is small and not under the control of the guest, so effectively exploiting this vulnerability is probably difficult.
The Xen Project reports:
Both writes to the FS and GS register base MSRs as well as the WRFSBASE and WRGSBASE instructions require their input values to be canonical, or a #GP fault will be raised. When the use of those instructions by the hypervisor was enabled, the previous guard against #GP faults (having recovery code attached) was accidentally removed.
A malicious guest administrator can crash the host, leading to a DoS.
The Xen Project reports:
LDTR, just like TR, is purely a protected mode facility. Hence even when switching to a VM86 mode task, LDTR loading needs to follow protected mode semantics. This was violated by the code.
On SVM (AMD hardware): a malicious unprivileged guest process can escalate its privilege to that of the guest operating system.
On both SVM and VMX (Intel hardware): a malicious unprivileged guest process can crash the guest.
The Xen Project reports:
The Xen x86 emulator erroneously failed to consider the unusability of segments when performing memory accesses.
The intended behaviour is as follows: The user data segment (%ds, %es, %fs and %gs) selectors may be NULL in 32-bit to prevent access. In 64-bit, NULL has a special meaning for user segments, and there is no way of preventing access. However, in both 32-bit and 64-bit, a NULL LDT system segment is intended to prevent access.
On Intel hardware, loading a NULL selector zeros the base as well as most attributes, but sets the limit field to its largest possible value. On AMD hardware, loading a NULL selector zeros the attributes, leaving the stale base and limit intact.
Xen may erroneously permit the access using unexpected base/limit values.
Ability to exploit this vulnerability on Intel is easy, but on AMD depends in a complicated way on how the guest kernel manages LDTs.
An unprivileged guest user program may be able to elevate its privilege to that of the guest operating system.
The Xen Project reports:
Instructions touching FPU, MMX, or XMM registers are required to raise a Device Not Available Exception (#NM) when either CR0.EM or CR0.TS are set. (Their AVX or AVX-512 extensions would consider only CR0.TS.) While during normal operation this is ensured by the hardware, if a guest modifies instructions while the hypervisor is preparing to emulate them, the #NM delivery could be missed.
Guest code in one task may thus (unintentionally or maliciously) read or modify register state belonging to another task in the same VM.
A malicious unprivileged guest user may be able to obtain or corrupt sensitive information (including cryptographic material) in other programs in the same guest.
The Xen Project reports:
When the EVTCHNOP_init_control operation is called with a bad guest frame number, it takes an error path which frees a control structure without also clearing the corresponding pointer. Certain subsequent operations (EVTCHNOP_expand_array or another EVTCHNOP_init_control), upon finding the non-NULL pointer, continue operation assuming it points to allocated memory.
A malicious guest administrator can crash the host, leading to a DoS. Arbitrary code execution (and therefore privilege escalation), and information leaks, cannot be excluded.
The Xen Project reports:
x86 HVM guests running with shadow paging use a subset of the x86 emulator to handle the guest writing to its own pagetables. There are situations a guest can provoke which result in exceeding the space allocated for internal state.
A malicious HVM guest administrator can cause Xen to fail a bug check, causing a denial of service to the host.
The Xen Project reports:
When emulating HVM instructions, Xen uses a small i-cache for fetches from guest memory. The code that handles cache misses does not check if the address from which it fetched lies within the cache before blindly writing to it. As such it is possible for the guest to overwrite hypervisor memory.
It is currently believed that the only way to trigger this bug is to use the way that Xen currently incorrectly wraps CS:IP in 16 bit modes. The included patch prevents such wrapping.
A malicious HVM guest administrator can escalate their privilege to that of the host.
The Xen Project reports:
On real hardware, a 32-bit PAE guest must leave the USER and RW bit clear in L3 pagetable entries, but the pagetable walk behaves as if they were set. (The L3 entries are cached in processor registers, and don't actually form part of the pagewalk.)
When running a 32-bit PV guest on a 64-bit Xen, Xen must always OR in the USER and RW bits for L3 updates for the guest to observe architectural behaviour. This is unsafe in combination with recursive pagetables.
As there is no way to construct an L3 recursive pagetable in native 32-bit PAE mode, disallow this option in 32-bit PV guests.
A malicious 32-bit PV guest administrator can escalate their privilege to that of the host.

Mitre reports:
The HTBoundary_put_block function in HTBound.c for W3C libwww (w3c-libwww) allows remote servers to cause a denial of service (segmentation fault) via a crafted multipart/byteranges MIME message that triggers an out-of-bounds read.
The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720.
The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625.
The Mozilla Foundation reports:
Redirection from an HTTP connection to a data: URL assigns the referring site's origin to the data: URL in some circumstances. This can result in same-origin violations against a domain if it loads resources from malicious sites. Cross-origin setting of cookies has been demonstrated without the ability to read them.
The Roundcube project reports
steps/mail/sendmail.inc in Roundcube before 1.1.7 and 1.2.x before 1.2.3, when no SMTP server is configured and the sendmail program is enabled, does not properly restrict the use of custom envelope-from addresses on the sendmail command line, which allows remote authenticated users to execute arbitrary code via a modified HTTP request that sends a crafted e-mail message.
The Drupal development team reports:
Inconsistent name for term access query (Less critical - Drupal 7 and Drupal 8)
Drupal provides a mechanism to alter database SELECT queries before they are executed. Contributed and custom modules may use this mechanism to restrict access to certain entities by implementing hook_query_alter() or hook_query_TAG_alter() in order to add additional conditions. Queries can be distinguished by means of query tags. As the documentation on EntityFieldQuery::addTag() suggests, access-tags on entity queries normally follow the form ENTITY_TYPE_access (e.g. node_access). However, the taxonomy module's access query tag predated this system and used term_access as the query tag instead of taxonomy_term_access.
As a result, before this security release modules wishing to restrict access to taxonomy terms may have implemented an unsupported tag, or needed to look for both tags (term_access and taxonomy_term_access) in order to be compatible with queries generated both by Drupal core as well as those generated by contributed modules like Entity Reference. Otherwise information on taxonomy terms might have been disclosed to unprivileged users.
Incorrect cache context on password reset page (Less critical - Drupal 8)
The user password reset form does not specify a proper cache context, which can lead to cache poisoning and unwanted content on the page.
Confirmation forms allow external URLs to be injected (Moderately critical - Drupal 7)
Under certain circumstances, malicious users could construct a URL to a confirmation form that would trick users into being redirected to a 3rd party website after interacting with the form, thereby exposing the users to potential social engineering attacks.
Denial of service via transliterate mechanism (Moderately critical - Drupal 8)
A specially crafted URL can cause a denial of service via the transliterate mechanism.

OpenSSL reports:
- ChaCha20/Poly1305 heap-buffer-overflow (CVE-2016-7054)
Severity: High
TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to a DoS attack by corrupting larger payloads. This can result in an OpenSSL crash. This issue is not considered to be exploitable beyond a DoS.- CMS Null dereference (CVE-2016-7053)
Severity: Medium
Applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected.- Montgomery multiplication may produce incorrect results (CVE-2016-7055)i
Severity: Low
There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure that handles input lengths divisible by, but longer than 256 bits.

[659475] High CVE-2016-5198: Out of bounds memory access in V8. Credit to Tencent Keen Security Lab, working with Trend Micro's Zero Day Initiative.
Due to improper handling of alert packets, OpenSSL would consume an excessive amount of CPU time processing undefined alert messages.
A remote attacker who can initiate handshakes with an OpenSSL based server can cause the server to consume a lot of computation power with very little bandwidth usage, and may be able to use this technique in a leveraged Denial of Service attack.

ISC reports:
A defect in BIND's handling of responses containing a DNAME answer can cause a resolver to exit after encountering an assertion failure in db.c or resolver.c
Cisco Talos reports:
Multiple integer overflow vulnerabilities exist within Memcached that could be exploited to achieve remote code execution on the targeted system. These vulnerabilities manifest in various Memcached functions that are used in inserting, appending, prepending, or modifying key-value data pairs. Systems which also have Memcached compiled with support for SASL authentication are also vulnerable to a third flaw due to how Memcached handles SASL authentication commands.
An attacker could exploit these vulnerabilities by sending a specifically crafted Memcached command to the targeted server. Additionally, these vulnerabilities could also be exploited to leak sensitive process information which an attacker could use to bypass common exploitation mitigations, such as ASLR, and can be triggered multiple times. This enables reliable exploitation which makes these vulnerabilities severe.

Apache Axis2 reports:
Apache Axis2 1.7.4 is a maintenance release that includes fixes for several issues, including the following security issues: Session fixation (AXIS2-4739) and XSS (AXIS2-5683) vulnerabilities affecting the admin console. A dependency on an Apache HttpClient version affected by known security vulnerabilities (CVE-2012-6153 and CVE-2014-3577); see AXIS2-5757.
Node.js has released new versions containing the following security fix:
The following releases all contain fixes for CVE-2016-5180 "ares_create_query single byte out of buffer write": Node.js v0.10.48 (Maintenance), Node.js v0.12.17 (Maintenance), Node.js v4.6.1 (LTS "Argon")
While this is not a critical update, all users of these release lines should upgrade at their earliest convenience.
Node.js v6.9.0 LTS contains the following security fixes, specific to v6.x:
Disable auto-loading of openssl.cnf: Don't automatically attempt to load an OpenSSL configuration file, from the OPENSSL_CONF environment variable or from the default location for the current platform. Always triggering a configuration file load attempt may allow an attacker to load compromised OpenSSL configuration into a Node.js process if they are able to place a file in a default location.
Patched V8 arbitrary memory read (CVE-2016-5172): The V8 parser mishandled scopes, potentially allowing an attacker to obtain sensitive information from arbitrary memory locations via crafted JavaScript code. This vulnerability would require an attacker to be able to execute arbitrary JavaScript code in a Node.js process.
Create a unique v8_inspector WebSocket address: Generate a UUID for each execution of the inspector. This provides additional security to prevent unauthorized clients from connecting to the Node.js process via the v8_inspector port when running with --inspect. Since the debugging protocol allows extensive access to the internals of a running process, and the execution of arbitrary code, it is important to limit connections to authorized tools only. Note that the v8_inspector protocol in Node.js is still considered an experimental feature. Vulnerability originally reported by Jann Horn.
All of these vulnerabilities are considered low-severity for Node.js users, however, users of Node.js v6.x should upgrade at their earliest convenience.

Adobe reports:
Adobe has released security updates for Adobe Flash Player for Windows, Macintosh, Linux and Chrome OS. These updates address a critical vulnerability that could potentially allow an attacker to take control of the affected system.
Adobe is aware of a report that an exploit for CVE-2016-7855 exists in the wild, and is being used in limited, targeted attacks against users running Windows versions 7, 8.1 and 10.
An unchecked array reference in the VGA device emulation code could potentially allow guests access to the heap of the bhyve process. Since the bhyve process is running as root, this may allow guests to obtain full control of the hosts they are running on.
For bhyve virtual machines with the "fbuf" framebuffer device configured, if exploited, a malicious guest could obtain full access to not just the host system, but to other virtual machines running on the system.

The Tor Blog reports:
Prevent a class of security bugs caused by treating the contents of a buffer chunk as if they were a NUL-terminated string. At least one such bug seems to be present in all currently used versions of Tor, and would allow an attacker to remotely crash most Tor instances, especially those compiled with extra compiler hardening. With this defense in place, such bugs can't crash Tor, though we should still fix them as they occur. Closes ticket 20384 (TROVE-2016-10-001).

Tencent's Xuanwu LAB reports:
A Heap Buffer Overflow (Out-of-Bounds Write) issue was found in function opj_dwt_interleave_v of dwt.c. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenJPEG.
An integer overflow issue exists in function opj_pi_create_decode of pi.c. It can lead to Out-Of-Bounds Read and Out-Of-Bounds Write in function opj_pi_next_cprl of pi.c (function opj_pi_next_lrcp, opj_pi_next_rlcp, opj_pi_next_rpcl, opj_pi_next_pcrl may also be vulnerable). This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenJPEG.
Redis team reports:
The redis-cli history file (in linenoise) is created with the default OS umask value which makes it world readable in most systems and could potentially expose authentication credentials to other users.
Flaws in libarchive's handling of symlinks and hard links allow overwriting files outside the extraction directory, or permission changes to a directory outside the extraction directory.
An attacker who can control freebsd-update's or portsnap's input to tar(1) can change file content or permissions on files outside of the update tool's working sandbox.
Flaws in portsnap's verification of downloaded tar files allows additional files to be included without causing the verification to fail. Portsnap may then use or execute these files.
An attacker who can conduct man in the middle attack on the network at the time when portsnap is run can cause portsnap to execute arbitrary commands under the credentials of the user who runs portsnap, typically root.
The implementation of bspatch is susceptible to integer overflows with carefully crafted input, potentially allowing an attacker who can control the patch file to write at arbitrary locations in the heap. This issue was partially addressed in FreeBSD-SA-16:25.bspatch, but some possible integer overflows remained.
An attacker who can control the patch file can cause a crash or run arbitrary code under the credentials of the user who runs bspatch, in many cases, root.
Moritz Bunkus reports:
most of the bugs fixed on 2016-09-06 and 2016-09-07 for issue #1780 are potentially exploitable. The scenario is arbitrary code execution with specially-crafted files.
Matthieu Herrb reports:
Tobias Stoeckmann from the OpenBSD project has discovered a number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues. These issue come in addition to the ones discovered by Ilja van Sprundel in 2013.
Most of these issues stem from the client libraries trusting the server to send correct protocol data, and not verifying that the values will not overflow or cause other damage. Most of the time X clients and servers are run by the same user, with the server more privileged than the clients, so this is not a problem, but there are scenarios in which a privileged client can be connected to an unprivileged server, for instance, connecting a setuid X client (such as a screen lock program) to a virtual X server (such as Xvfb or Xephyr) which the user has modified to return invalid data, potentially allowing the user to escalate their privileges.
ISC reports:
Testing by ISC has uncovered a critical error condition which can occur when a nameserver is constructing a response. A defect in the rendering of messages into packets can cause named to exit with an assertion failure in buffer.c while constructing a response to a query that meets certain criteria.

Matt Johnston reports:
If specific usernames including "%" symbols can be created on a system (validated by getpwnam()) then an attacker could run arbitrary code as root when connecting to Dropbear server. A dbclient user who can control username or host arguments could potentially run arbitrary code as the dbclient user. This could be a problem if scripts or webpages pass untrusted input to the dbclient program.
dropbearconvert import of OpenSSH keys could run arbitrary code as the local dropbearconvert user when parsing malicious key files.
dbclient could run arbitrary code as the local dbclient user if particular -m or -c arguments are provided. This could be an issue where dbclient is used in scripts.
dbclient or dropbear server could expose process memory to the running user if compiled with DEBUG_TRACE and running with -v

The cURL project reports
The four libcurl functions curl_escape(), curl_easy_escape(), curl_unescape and curl_easy_unescape perform string URL percent escaping and unescaping. They accept custom string length inputs in signed integer arguments.
The provided string length arguments were not properly checked and due to arithmetic in the functions, passing in the length 0xffffffff (2^32-1 or UINT_MAX or even just -1) would end up causing an allocation of zero bytes of heap memory that curl would attempt to write gigabytes of data into.

Dawid Golunski reports:
An independent research has revealed multiple severe MySQL vulnerabilities. This advisory focuses on a critical vulnerability with a CVEID of CVE-2016-6662 which can allow attackers to (remotely) inject malicious settings into MySQL configuration files (my.cnf) leading to critical consequences.
Florian Weimer of Redhat discovered that an optimization in RSA signature validation can result in disclosure of the server's private key under certain fault conditions.
Sebastian Ramacher identified an error in wolfSSL's implementation of the server side of the DTLS handshake, which could be abused for DDoS amplification or a DoS on the DTLS server itself.

The Asterisk project reports:
The overlap dialing feature in chan_sip allows chan_sip to report to a device that the number that has been dialed is incomplete and more digits are required. If this functionality is used with a device that has performed username/password authentication RTP resources are leaked. This occurs because the code fails to release the old RTP resources before allocating new ones in this scenario. If all resources are used then RTP port exhaustion will occur and no RTP sessions are able to be set up.
If overlap dialing support is not needed the "allowoverlap" option can be set to no. This will stop any usage of the scenario which causes the resource exhaustion.
The Asterisk project reports:
Asterisk can be crashed remotely by sending an ACK to it from an endpoint username that Asterisk does not recognize. Most SIP request types result in an "artificial" endpoint being looked up, but ACKs bypass this lookup. The resulting NULL pointer results in a crash when attempting to determine if ACLs should be applied.
This issue was introduced in the Asterisk 13.10 release and only affects that release.
This issue only affects users using the PJSIP stack with Asterisk. Those users that use chan_sip are unaffected.
Adam reports:
A serious vulnerability exists in when using m_sasl in combination with any services that support SASL EXTERNAL. To be vulnerable you must have m_sasl loaded, and have services which support SASL EXTERNAL authentication.
The late Tokio Kikuchi reported:
We may have to set lifetime for input forms because of recent activities on cross-site request forgery (CSRF). The form lifetime is successfully deployed in frameworks like web.py or plone etc. Proposed branch lp:~tkikuchi/mailman/form-lifetime implement lifetime in admin, admindb, options and edithtml interfaces. [...]
The web admin interface has been hardened against CSRF attacks by adding a hidden, encrypted token with a time stamp to form submissions and not accepting authentication by cookie if the token is missing, invalid or older than the new mm_cfg.py setting FORM_LIFETIME which defaults to one hour. Posthumous thanks go to Tokio Kikuchi for this implementation [...].
The OpenSSH project reports:
* sshd(8): Mitigate timing differences in password authentication that could be used to discern valid from invalid account names when long passwords were sent and particular password hashing algorithms are in use on the server. CVE-2016-6210, reported by EddieEzra.Harari at verint.com
* sshd(8): (portable only) Ignore PAM environment vars when UseLogin=yes. If PAM is configured to read user-specified environment variables and UseLogin=yes in sshd_config, then a hostile local user may attack /bin/login via LD_PRELOAD or similar environment variables set via PAM. CVE-2015-8325, found by Shayan Sadigh.
Mark Sapiro reports:
CSRF protection has been extended to the user options page. This was actually fixed by Tokio Kikuchi as part of the fix for LP: #775294 and intended for Mailman 2.1.15, but that fix wasn't completely merged at the time. The full fix also addresses the admindb, and edithtml pages as well as the user options page and the previously fixed admin pages. Thanks to Nishant Agarwala for reporting the issue.

Hanz Jenson audit report:
I found 10 vulnerabilities. Some of these are critical and allow remote code execution. For the average user, that means that these vulnerabilities can be exploited by a malicious attacker in order to take over any Teamspeak server, not only becoming serveradmin, but getting a shell on the affected machine.
Puppet reports:
Puppet Enterprise previously included a puppet-agent MCollective plugin that allowed you to pass the `--server` argument to MCollective. This insecure argument enabled remote code execution via connection to an untrusted host. The puppet-agent MCollective version included in PE 2016.2.1, this option is disabled by default.
The implementation of bspatch does not check for a negative value on numbers of bytes read from the diff and extra streams, allowing an attacker who can control the patch file to write at arbitrary locations in the heap.
This issue was first discovered by The Chromium Project and reported independently by Lu Tung-Pin to the FreeBSD project.
An attacker who can control the patch file can cause a crash or run arbitrary code under the credentials of the user who runs bspatch, in many cases, root.
Multiple vulnerabilities have been discovered in the NTP suite:
The fix for Sec 3007 in ntp-4.2.8p7 contained a bug that could cause ntpd to crash. [CVE-2016-4957, Reported by Nicolas Edet of Cisco]
An attacker who knows the origin timestamp and can send a spoofed packet containing a CRYPTO-NAK to an ephemeral peer target before any other response is sent can demobilize that association. [CVE-2016-4953, Reported by Miroslav Lichvar of Red Hat]
An attacker who is able to spoof packets with correct origin timestamps from enough servers before the expected response packets arrive at the target machine can affect some peer variables and, for example, cause a false leap indication to be set. [CVE-2016-4954, Reported by Jakub Prokes of Red Hat]
An attacker who is able to spoof a packet with a correct origin timestamp before the expected response packet arrives at the target machine can send a CRYPTO_NAK or a bad MAC and cause the association's peer variables to be cleared. If this can be done often enough, it will prevent that association from working. [CVE-2016-4955, Reported by Miroslav Lichvar of Red Hat]
The fix for NtpBug2978 does not cover broadcast associations, so broadcast clients can be triggered to flip into interleave mode. [CVE-2016-4956, Reported by Miroslav Lichvar of Red Hat.]
Malicious remote attackers may be able to break time synchronization, or cause the ntpd(8) daemon to crash.
The implementation of historic stat(2) system call does not clear the output struct before copying it out to userland.
An unprivileged user can read a portion of uninitialised kernel stack data, which may contain sensitive information, such as the stack guard, portions of the file cache or terminal buffers, which an attacker might leverage to obtain elevated privileges.
The implementation of the TIOCGSERIAL ioctl(2) does not clear the output struct before copying it out to userland.
The implementation of the Linux sysinfo() system call does not clear the output struct before copying it out to userland.
An unprivileged user can read a portion of uninitialised kernel stack data, which may contain sensitive information, such as the stack guard, portions of the file cache or terminal buffers, which an attacker might leverage to obtain elevated privileges.
Incorrect argument handling in the socket code allows malicious local user to overwrite large portion of the kernel memory.
Malicious local user may crash kernel or execute arbitrary code in the kernel, potentially gaining superuser privileges.
Incorrect signedness comparison in the ioctl(2) handler allows a malicious local user to overwrite a portion of the kernel memory.
A local user may crash the kernel, read a portion of kernel memory and execute arbitrary code in kernel context. The result of executing an arbitrary kernel code is privilege escalation.
A special combination of sysarch(2) arguments, specify a request to uninstall a set of descriptors from the LDT. The start descriptor is cleared and the number of descriptors are provided. Due to lack of sufficient bounds checking during argument validity verification, unbound zero'ing of the process LDT and adjacent memory can be initiated from usermode.
This vulnerability could cause the kernel to panic. In addition it is possible to perform a local Denial of Service against the system by unprivileged processes.
A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable servers can be decrypted provided another server supporting SSLv2 and EXPORT ciphers (even with a different protocol such as SMTP, IMAP or POP3) shares the RSA keys of the non-vulnerable server. This vulnerability is known as DROWN. [CVE-2016-0800]
A double free bug was discovered when OpenSSL parses malformed DSA private keys and could lead to a DoS attack or memory corruption for applications that receive DSA private keys from untrusted sources. This scenario is considered rare. [CVE-2016-0705]
The SRP user database lookup method SRP_VBASE_get_by_user had confusing memory management semantics; the returned pointer was sometimes newly allocated, and sometimes owned by the callee. The calling code has no way of distinguishing these two cases. [CVE-2016-0798]
In the BN_hex2bn function, the number of hex digits is calculated using an int value |i|. Later |bn_expand| is called with a value of |i * 4|. For large values of |i| this can result in |bn_expand| not allocating any memory because |i * 4| is negative. This can leave the internal BIGNUM data field as NULL leading to a subsequent NULL pointer dereference. For very large values of |i|, the calculation |i * 4| could be a positive value smaller than |i|. In this case memory is allocated to the internal BIGNUM data field, but it is insufficiently sized leading to heap corruption. A similar issue exists in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn is ever called by user applications with very large untrusted hex/dec data. This is anticipated to be a rare occurrence. [CVE-2016-0797]
The internal |fmtstr| function used in processing a "%s" formatted string in the BIO_*printf functions could overflow while calculating the length of a string and cause an out-of-bounds read when printing very long strings. [CVE-2016-0799]
A side-channel attack was found which makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture which could lead to the recovery of RSA keys. [CVE-2016-0702]
s2_srvr.c did not enforce that clear-key-length is 0 for non-export ciphers. If clear-key bytes are present for these ciphers, they displace encrypted-key bytes. [CVE-2016-0703]
s2_srvr.c overwrites the wrong bytes in the master key when applying Bleichenbacher protection for export cipher suites. [CVE-2016-0704]
Servers that have SSLv2 protocol enabled are vulnerable to the "DROWN" attack which allows a remote attacker to fast attack many recorded TLS connections made to the server, even when the client did not make any SSLv2 connections themselves.
An attacker who can supply malformed DSA private keys to OpenSSL applications may be able to cause memory corruption which would lead to a Denial of Service condition. [CVE-2016-0705]
An attacker connecting with an invalid username can cause memory leak, which could eventually lead to a Denial of Service condition. [CVE-2016-0798]
An attacker who can inject malformed data into an application may be able to cause memory corruption which would lead to a Denial of Service condition. [CVE-2016-0797, CVE-2016-0799]
A local attacker who has control of code in a thread running on the same hyper-threaded core as the victim thread which is performing decryptions could recover RSA keys. [CVE-2016-0702]
An eavesdropper who can intercept SSLv2 handshake can conduct an efficient divide-and-conquer key recovery attack and use the server as an oracle to determine the SSLv2 master-key, using only 16 connections to the server and negligible computation. [CVE-2016-0703]
An attacker can use the Bleichenbacher oracle, which enables more efficient variant of the DROWN attack. [CVE-2016-0704]
A programming error in the Linux compatibility layer could cause the issetugid(2) system call to return incorrect information.
If an application relies on output of the issetugid(2) system call and that information is incorrect, this could lead to a privilege escalation.
The SNMP protocol supports an authentication model called USM, which relies on a shared secret. The default permission of the snmpd configuration file, /etc/snmpd.config, is weak and does not provide adequate protection against local unprivileged users.
A local user may be able to read the shared secret, if configured and used by the system administrator.
A programming error in processing a TCP connection with both TCP_MD5SIG and TCP_NOOPT socket options may lead to kernel crash.
A local attacker can crash the kernel, resulting in a denial-of-service.
A remote attack is theoretically possible, if server has a listening socket with TCP_NOOPT set, and server is either out of SYN cache entries, or SYN cache is disabled by configuration.
A programming error in the Linux compatibility layer setgroups(2) system call can lead to an unexpected results, such as overwriting random kernel memory contents.
It is possible for a local attacker to overwrite portions of kernel memory, which may result in a privilege escalation or cause a system panic.
A programming error in the handling of Linux futex robust lists may result in incorrect memory locations being accessed.
It is possible for a local attacker to read portions of kernel memory, which may result in a privilege escalation.
A lack of proper input checks in the ICMPv6 processing in the SCTP stack can lead to either a failed kernel assertion or to a NULL pointer dereference. In either case, a kernel panic will follow.
A remote, unauthenticated attacker can reliably trigger a kernel panic in a vulnerable system running IPv6. Any kernel compiled with both IPv6 and SCTP support is vulnerable. There is no requirement to have an SCTP socket open.
IPv4 ICMP processing is not impacted by this vulnerability.
In rpcbind(8), netbuf structures are copied directly, which would result in two netbuf structures that reference to one shared address buffer. When one of the two netbuf structures is freed, access to the other netbuf structure would result in an undefined result that may crash the rpcbind(8) daemon.
A remote attacker who can send specifically crafted packets to the rpcbind(8) daemon can cause it to crash, resulting in a denial of service condition.
If the kernel-mode IRET instruction generates an #SS or #NP exception, but the exception handler does not properly ensure that the right GS register base for kernel is reloaded, the userland GS segment may be used in the context of the kernel exception handler.
By causing an IRET with #SS or #NP exceptions, a local attacker can cause the kernel to use an arbitrary GS base, which may allow escalated privileges or panic the system.
Multiple integer overflows have been discovered in the XML_GetBuffer() function in the expat library.
The integer overflows may be exploited by using specifically crafted XML data and lead to infinite loop, or a heap buffer overflow, which results in a Denial of Service condition, or enables remote attackers to execute arbitrary code.
The input path in routed(8) will accept queries from any source and attempt to answer them. However, the output path assumes that the destination address for the response is on a directly connected network.
Upon receipt of a query from a source which is not on a directly connected network, routed(8) will trigger an assertion and terminate. The affected system's routing table will no longer be updated. If the affected system is a router, its routes will eventually expire from other routers' routing tables, and its networks will no longer be reachable unless they are also connected to another router.
Due to insufficient sanitization of the input patch stream, it is possible for a patch file to cause patch(1) to pass certain ed(1) scripts to the ed(1) editor, which would run commands.
This issue could be exploited to execute arbitrary commands as the user invoking patch(1) against a specially crafted patch file, which could be leveraged to obtain elevated privileges.
There is a mistake with the introduction of VNET, which converted the global limit on the number of segments that could belong to reassembly queues into a per-VNET limit. Because mbufs are allocated from a global pool, in the presence of a sufficient number of VNETs, the total number of mbufs attached to reassembly queues can grow to the total number of mbufs in the system, at which point all network traffic would cease.
An attacker who can establish concurrent TCP connections across a sufficient number of VNETs and manipulate the inbound packet streams such that the maximum number of mbufs are enqueued on each reassembly queue can cause mbuf cluster exhaustion on the target system, resulting in a Denial of Service condition.
As the default per-VNET limit on the number of segments that can belong to reassembly queues is 1/16 of the total number of mbuf clusters in the system, only systems that have 16 or more VNET instances are vulnerable.
Due to insufficient sanitization of the input patch stream, it is possible for a patch file to cause patch(1) to run commands in addition to the desired SCCS or RCS commands.
This issue could be exploited to execute arbitrary commands as the user invoking patch(1) against a specially crafted patch file, which could be leveraged to obtain elevated privileges.
TCP connections transitioning to the LAST_ACK state can become permanently stuck due to mishandling of protocol state in certain situations, which in turn can lead to accumulated consumption and eventual exhaustion of system resources, such as mbufs and sockets.
An attacker who can repeatedly establish TCP connections to a victim system (for instance, a Web server) could create many TCP connections that are stuck in LAST_ACK state and cause resource exhaustion, resulting in a denial of service condition. This may also happen in normal operation where no intentional attack is conducted, but an attacker who can send specifically crafted packets can trigger this more reliably.
The Neighbor Discover Protocol allows a local router to advertise a suggested Current Hop Limit value of a link, which will replace Current Hop Limit on an interface connected to the link on the FreeBSD system.
When the Current Hop Limit (similar to IPv4's TTL) is small, IPv6 packets may get dropped before they reached their destinations.
By sending specifically crafted Router Advertisement packets, an attacker on the local network can cause the FreeBSD system to lose the ability to communicate with another IPv6 node on a different network.
The default permission set by bsdinstall(8) installer when configuring full disk encrypted ZFS is too open.
A local attacker may be able to get a copy of the geli(8) provider's keyfile which is located at a fixed location.
An integer overflow in computing the size of IGMPv3 data buffer can result in a buffer which is too small for the requested operation.
An attacker who can send specifically crafted IGMP packets could cause a denial of service situation by causing the kernel to crash.
The input validation of received SCTP RE_CONFIG chunks is insufficient, and can result in a NULL pointer deference later.
A remote attacker who can send a malformed SCTP packet to a FreeBSD system that serves SCTP can cause a kernel panic, resulting in a Denial of Service.
Due to insufficient validation of the SCTP stream ID, which serves as an array index, a local unprivileged attacker can read or write 16-bits of kernel memory.
An unprivileged process can read or modify 16-bits of memory which belongs to the kernel. This may lead to exposure of sensitive information or allow privilege escalation.
A programming error in the standard I/O library's __sflush() function could erroneously adjust the buffered stream's internal state even when no write actually occurred in the case when write(2) system call returns an error.
The accounting mismatch would accumulate, if the caller does not check for stream status and will eventually lead to a heap buffer overflow.
Such overflows may lead to data corruption or the execution of arbitrary code at the privilege level of the calling program.
A malicious HTTP server could cause ftp(1) to execute arbitrary commands.
When operating on HTTP URIs, the ftp(1) client follows HTTP redirects, and uses the part of the path after the last '/' from the last resource it accesses as the output filename if '-o' is not specified.
If the output file name provided by the server begins with a pipe ('|'), the output is passed to popen(3), which might be used to execute arbitrary commands on the ftp(1) client machine.
When setlogin(2) is called while setting up a new login session, the login name is copied into an uninitialized stack buffer, which is then copied into a buffer of the same size in the session structure. The getlogin(2) system call returns the entire buffer rather than just the portion occupied by the login name associated with the session.
An unprivileged user can access this memory by calling getlogin(2) and reading beyond the terminating NUL character of the resulting string. Up to 16 (FreeBSD 8) or 32 (FreeBSD 9 and 10) bytes of kernel memory may be leaked in this manner for each invocation of setlogin(2).
This memory may contain sensitive information, such as portions of the file cache or terminal buffers, which an attacker might leverage to obtain elevated privileges.
Although OpenSSH is not multithreaded, when OpenSSH is compiled with Kerberos support, the Heimdal libraries bring in the POSIX thread library as a dependency. Due to incorrect library ordering while linking sshd(8), symbols in the C library which are shadowed by the POSIX thread library may not be resolved correctly at run time.
Note that this problem is specific to the FreeBSD build system and does not affect other operating systems or the version of OpenSSH available from the FreeBSD ports tree.
An incorrectly linked sshd(8) child process may deadlock while handling an incoming connection. The connection may then time out or be interrupted by the client, leaving the deadlocked sshd(8) child process behind. Eventually, the sshd(8) parent process stops accepting new connections.
An attacker may take advantage of this by repeatedly connecting and then dropping the connection after having begun, but not completed, the authentication process.
The namei facility will leak a small amount of kernel memory every time a sandboxed process looks up a nonexistent path name.
A remote attacker that can cause a sandboxed process (for instance, a web server) to look up a large number of nonexistent path names can cause memory exhaustion.
The input path in routed(8) will accept queries from any source and attempt to answer them. However, the output path assumes that the destination address for the response is on a directly connected network.
Upon receipt of a query from a source which is not on a directly connected network, routed(8) will trigger an assertion and terminate. The affected system's routing table will no longer be updated. If the affected system is a router, its routes will eventually expire from other routers' routing tables, and its networks will no longer be reachable unless they are also connected to another router.
Due to a missing length check in the code that handles DNS parameters, a malformed router advertisement message can result in a stack buffer overflow in rtsold(8).
Receipt of a router advertisement message with a malformed DNSSL option, for instance from a compromised host on the same network, can cause rtsold(8) to crash.
While it is theoretically possible to inject code into rtsold(8) through malformed router advertisement messages, it is normally compiled with stack protection enabled, rendering such an attack extremely difficult.
When rtsold(8) crashes, the existing DNS configuration will remain in force, and the kernel will continue to receive and process periodic router advertisements.
When a segment with the SYN flag for an already existing connection arrives, the TCP stack tears down the connection, bypassing a check that the sequence number in the segment is in the expected window.
An attacker who has the ability to spoof IP traffic can tear down a TCP connection by sending only 2 packets, if they know both TCP port numbers. In case one of the two port numbers is unknown, a successful attack requires less than 2**17 packets spoofed, which can be generated within less than a second on a decent connection to the Internet.
Buffer between control message header and data may not be completely initialized before being copied to userland. [CVE-2014-3952]
Three SCTP cmsgs, SCTP_SNDRCV, SCTP_EXTRCV and SCTP_RCVINFO, have implicit padding that may not be completely initialized before being copied to userland. In addition, three SCTP notifications, SCTP_PEER_ADDR_CHANGE, SCTP_REMOTE_ERROR and SCTP_AUTHENTICATION_EVENT, have padding in the returning data structure that may not be completely initialized before being copied to userland. [CVE-2014-3953]
An unprivileged local process may be able to retrieve portion of kernel memory.
For the generic control message, the process may be able to retrieve a maximum of 4 bytes of kernel memory.
For SCTP, the process may be able to retrieve 2 bytes of kernel memory for all three control messages, plus 92 bytes for SCTP_SNDRCV and 76 bytes for SCTP_EXTRCV. If the local process is permitted to receive SCTP notification, a maximum of 112 bytes of kernel memory may be returned to userland.
This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password.
A specifically crafted Composite Document File (CDF) file can trigger an out-of-bounds read or an invalid pointer dereference. [CVE-2012-1571]
A flaw in regular expression in the awk script detector makes use of multiple wildcards with unlimited repetitions. [CVE-2013-7345]
A malicious input file could trigger infinite recursion in libmagic(3). [CVE-2014-1943]
A specifically crafted Portable Executable (PE) can trigger out-of-bounds read. [CVE-2014-2270]
An attacker who can cause file(1) or any other applications using the libmagic(3) library to be run on a maliciously constructed input can the application to crash or consume excessive CPU resources, resulting in a denial-of-service.
A NULL pointer dereference in the initialization code of the HZ module and an out of bounds array access in the initialization code of the VIQR module make iconv_open(3) calls involving HZ or VIQR result in an application crash.
Services where an attacker can control the arguments of an iconv_open(3) call can be caused to crash resulting in a denial-of-service. For example, an email encoded in HZ may cause an email delivery service to crash if it converts emails to a more generic encoding like UTF-8 before applying filtering rules.
The OpenPAM library searches for policy definitions in several locations. While doing so, the absence of a policy file is a soft failure (handled by searching in the next location) while the presence of an invalid file is a hard failure (handled by returning an error to the caller).
The policy parser returns the same error code (ENOENT) when a syntactically valid policy references a non-existent module as when the requested policy file does not exist. The search loop regards this as a soft failure and looks for the next similarly-named policy, without discarding the partially-loaded configuration.
A similar issue can arise if a policy contains an include directive that refers to a non-existent policy.
If a module is removed, or the name of a module is misspelled in the policy file, the PAM library will proceed with a partially loaded configuration. Depending on the exact circumstances, this may result in a fail-open scenario where users are allowed to log in without a password, or with an incorrect password.
In particular, if a policy references a module installed by a package or port, and that package or port is being reinstalled or upgraded, there is a brief window of time during which the module is absent and policies that use it may fail open. This can be especially damaging to Internet-facing SSH servers, which are regularly subjected to brute-force scans.
Due to an overlooked merge to -STABLE branches, the size for page fault kernel trace entries was set incorrectly.
A user who can enable kernel process tracing could end up reading the contents of kernel memory.
Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.
There is a programming error in sendmail(8) that prevented open file descriptors have close-on-exec properly set. Consequently a subprocess will be able to access all open files that the parent process have open.
A local user who can execute their own program for mail delivery will be able to interfere with an open SMTP connection.
FreeBSD may add a reassemble queue entry on the stack into the segment list when the reassembly queue reaches its limit. The memory from the stack is undefined after the function returns. Subsequent iterations of the reassembly function will attempt to access this entry.
An attacker who can send a series of specifically crafted packets with a connection could cause a denial of service situation by causing the kernel to crash.
Additionally, because the undefined on stack memory may be overwritten by other kernel threads, while extremely difficult, it may be possible for an attacker to construct a carefully crafted attack to obtain portion of kernel memory via a connected socket. This may result in the disclosure of sensitive information such as login credentials, etc. before or even without crashing the system.
The default devfs rulesets are not loaded on boot, even when jails are used. Device nodes will be created in the jail with their normal default access permissions, while most of them should be hidden and inaccessible.
Jailed processes can get access to restricted resources on the host system. For jailed processes running with superuser privileges this implies access to all devices on the system. This level of access could lead to information leakage and privilege escalation.
The kernel holds a lock over the source directory vnode while trying to convert the target directory file handle to a vnode, which needs to be returned with the lock held, too. This order may be in violation of normal lock order, which in conjunction with other threads that grab locks in the right order, constitutes a deadlock condition because no thread can proceed.
An attacker on a trusted client could cause the NFS server become deadlocked, resulting in a denial of service.
Problem Description:
The bsnmpd(8) daemon is prone to a stack-based buffer-overflow when it has received a specifically crafted GETBULK PDU request.
Impact:
This issue could be exploited to execute arbitrary code in the context of the service daemon, or crash the service daemon, causing a denial-of-service.

ISC reports:
DNS protocols were designed with the assumption that a certain amount of trust could be presumed between the operators of primary and secondary servers for a given zone. However, in current practice some organizations have scenarios which require them to accept zone data from sources that are not fully trusted (for example: providers of secondary name service). A party who is allowed to feed data into a zone (e.g. by AXFR, IXFR, or Dynamic DNS updates) can overwhelm the server which is accepting data by intentionally or accidentally exhausting that server's memory.
Problem Description:
When initializing the SCTP state cookie being sent in INIT-ACK chunks, a buffer allocated from the kernel stack is not completely initialized.
Impact:
Fragments of kernel memory may be included in SCTP packets and transmitted over the network. For each SCTP session, there are two separate instances in which a 4-byte fragment may be transmitted.
This memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password.
Problem Description:
An integer overflow in computing the size of a temporary buffer can result in a buffer which is too small for the requested operation.
Impact:
An unprivileged process can read or write pages of memory which belong to the kernel. These may lead to exposure of sensitive information or allow privilege escalation.
Problem Description:
The kernel incorrectly uses client supplied credentials instead of the one configured in exports(5) when filling out the anonymous credential for a NFS export, when -network or -host restrictions are used at the same time.
Impact:
The remote client may supply privileged credentials (e.g. the root user) when accessing a file under the NFS share, which will bypass the normal access checks.

The Xen Project reports:
A guest can submit virtio requests without bothering to wait for completion and is therefore not bound by virtqueue size...
A malicious guest administrator can cause unbounded memory allocation in QEMU, which can cause an Out-of-Memory condition in the domain running qemu. Thus, a malicious guest administrator can cause a denial of service affecting the whole host.
The Xen Project reports:
Supervisor Mode Access Prevention is a hardware feature designed to make an Operating System more robust, by raising a pagefault rather than accidentally following a pointer into userspace. However, legitimate accesses into userspace require whitelisting, and the exception delivery mechanism for 32bit PV guests wasn't whitelisted.
A malicious 32-bit PV guest kernel can trigger a safety check, crashing the hypervisor and causing a denial of service to other VMs on the host.
The Xen Project reports:
The PV pagetable code has fast-paths for making updates to pre-existing pagetable entries, to skip expensive re-validation in safe cases (e.g. clearing only Access/Dirty bits). The bits considered safe were too broad, and not actually safe.
A malicious PV guest administrator can escalate their privilege to that of the host.

TYPO3 reports:
Extbase request handling fails to implement a proper access check for requested controller/ action combinations, which makes it possible for an attacker to execute arbitrary Extbase actions by crafting a special request. To successfully exploit this vulnerability, an attacker must have access to at least one Extbase plugin or module action in a TYPO3 installation. The missing access check inevitably leads to information disclosure or remote code execution, depending on the action that an attacker is able to execute.

Talos reports:
An exploitable Use After Free vulnerability exists in the RTF parser LibreOffice. A specially crafted file can cause a use after free resulting in a possible arbitrary code execution. To exploit the vulnerability a malicious file needs to be opened by the user via vulnerable application.
Mathias Svensson reports:
potential buffer write overrun in PixarLogDecode() on corrupted/unexpected images
Cisco Talos reports:
An out-of-bounds read vulnerability exists in the way 7-Zip handles Universal Disk Format (UDF) files.
Central to 7-Zip’s processing of UDF files is the CInArchive::ReadFileItem method. Because volumes can have more than one partition map, their objects are kept in an object vector. To start looking for an item, this method tries to reference the proper object using the partition map’s object vector and the "PartitionRef" field from the Long Allocation Descriptor. Lack of checking whether the "PartitionRef" field is bigger than the available amount of partition map objects causes a read out-of-bounds and can lead, in some circumstances, to arbitrary code execution.
Cisco Talos reports:
An exploitable heap overflow vulnerability exists in the NArchive::NHfs::CHandler::ExtractZlibFile method functionality of 7zip that can lead to arbitrary code execution.

A man in the middle attack can disable client signing over SMB2/3, even if enforced by configuration parameters.
RubySec reports:
ruby-saml prior to version 1.3.0 is vulnerable to an XML signature wrapping attack in the specific scenario where there was a signature that referenced at the same time 2 elements (but past the scheme validator process since 1 of the element was inside the encrypted assertion).
ruby-saml users must update to 1.3.0, which implements 3 extra validations to mitigate this kind of attack.
Mitre reports:
The onReadyRead function in core/coreauthhandler.cpp in Quassel before 0.12.4 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via invalid handshake data.
Apache Software Foundation reports:
The Apache HTTPD web server (from 2.4.18-2.4.20) did not validate a X509 client certificate correctly when experimental module for the HTTP/2 protocol is used to access a resource.
The net result is that a resource that should require a valid client certificate in order to get access can be accessed without that credential.
The Xen Project reports:
When the libxl toolstack launches qemu for HVM guests, it pipes the output of stderr to a file in /var/log/xen. This output is not rate-limited in any way. The guest can easily cause qemu to print messages to stderr, causing this file to become arbitrarily large.
The disk containing the logfile can be exhausted, possibly causing a denial-of-service (DoS).
The Xen Project reports:
Qemu VGA module allows banked access to video memory using the window at 0xa00000 and it supports different access modes with different address calculations.
Qemu VGA module allows guest to edit certain registers in 'vbe' and 'vga' modes.
A privileged guest user could use CVE-2016-3710 to exceed the bank address window and write beyond the said memory area, potentially leading to arbitrary code execution with privileges of the Qemu process. If the system is not using stubdomains, this will be in domain 0.
A privileged guest user could use CVE-2016-3712 to cause potential integer overflow or OOB read access issues in Qemu, resulting in a DoS of the guest itself. More dangerous effect, such as data leakage or code execution, are not known but cannot be ruled out.
The Xen Project reports:
libxl's device-handling code freely uses and trusts information from the backend directories in xenstore.
A malicious driver domain can deny service to management tools.
The Xen Project reports:
The Page Size (PS) page table entry bit exists at all page table levels other than L1. Its meaning is reserved in L4, and conditionally reserved in L3 and L2 (depending on hardware capabilities). The software page table walker in the hypervisor, however, so far ignored that bit in L4 and (on respective hardware) L3 entries, resulting in pages to be treated as page tables which the guest OS may not have designated as such. If the page in question is writable by an unprivileged user, then that user will be able to map arbitrary guest memory.
On vulnerable OSes, guest user mode code may be able to establish mappings of arbitrary memory inside the guest, allowing it to elevate its privileges inside the guest.
The Xen Project reports:
Various parts of libxl device-handling code inappropriately use information from (partially) guest controlled areas of xenstore.
A malicious guest administrator can cause denial of service by resource exhaustion.
A malicious guest administrator can confuse and/or deny service to management facilities.
A malicious guest administrator of a guest configured with channel devices may be able to escalate their privilege to that of the backend domain (i.e., normally, to that of the host).
The Xen Project reports:
In the x86 shadow pagetable code, the guest frame number of a superpage mapping is stored in a 32-bit field. If a shadowed guest can cause a superpage mapping of a guest-physical address at or above 2^44 to be shadowed, the top bits of the address will be lost, causing an assertion failure or NULL dereference later on, in code that removes the shadow.
A HVM guest using shadow pagetables can cause the host to crash.
A PV guest using shadow pagetables (i.e. being migrated) with PV superpages enabled (which is not the default) can crash the host, or corrupt hypervisor memory, and so a privilege escalation cannot be ruled out.

Possibility of remote code execution via the remote command transport.
Sushanth Sowmyan reports:
Some partition-level operations exist that do not explicitly also authorize privileges of the parent table. This can lead to issues when the parent table would have denied the operation, but no denial occurs because the partition-level privilege is not checked by the authorization framework, which defines authorization entities only from the table level upwards.
KoreLogic security reports:
Affected versions of SQLite reject potential tempdir locations if they are not readable, falling back to '.'. Thus, SQLite will favor e.g. using cwd for tempfiles on such a system, even if cwd is an unsafe location. Notably, SQLite also checks the permissions of '.', but ignores the results of that check.
Red Hat reports:
A vulnerability in smtplib allowing MITM attacker to perform a startTLS stripping attack. smtplib does not seem to raise an exception when the remote end (smtp server) is capable of negotiating starttls but fails to respond with 220 (ok) to an explicit call of SMTP.starttls(). This may allow a malicious MITM to perform a startTLS stripping attack if the client code does not explicitly check the response code for startTLS.

HTTP header injection in urrlib2/urllib/httplib/http.client with newlines in header values, where newlines have a semantic consequence of denoting the start of an additional header line.
Mitre reports:
OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.
Mark Thomas reports:
CVE-2016-3092 is a denial of service vulnerability that has been corrected in the Apache Commons FileUpload component. It occurred when the length of the multipart boundary was just below the size of the buffer (4096 bytes) used to read the uploaded file. This caused the file upload process to take several orders of magnitude longer than if the boundary length was the typical tens of bytes.

Open vSwitch reports:
Multiple versions of Open vSwitch are vulnerable to remote buffer overflow attacks, in which crafted MPLS packets could overflow the buffer reserved for MPLS labels in an OVS internal data structure. The MPLS packets that trigger the vulnerability and the potential for exploitation vary depending on version:
Open vSwitch 2.1.x and earlier are not vulnerable.
In Open vSwitch 2.2.x and 2.3.x, the MPLS buffer overflow can be exploited for arbitrary remote code execution.
In Open vSwitch 2.4.x, the MPLS buffer overflow does not obviously lead to a remote code execution exploit, but testing shows that it can allow a remote denial of service. See the mitigation section for details.
Open vSwitch 2.5.x is not vulnerable.

Logstash developers report:
Passwords Printed in Log Files under Some Conditions
It was discovered that, in Logstash 2.1.0+, log messages generated by a stalled pipeline during shutdown will print plaintext contents of password fields. While investigating this issue we also discovered that debug logging has included this data for quite some time. Our latest releases fix both leaks. You will want to scrub old log files if this is of particular concern to you. This was fixed in issue #4965
Subversion project reports:
svnserve, the svn:// protocol server, can optionally use the Cyrus SASL library for authentication, integrity protection, and encryption. Due to a programming oversight, authentication against Cyrus SASL would permit the remote user to specify a realm string which is a prefix of the expected realm string.
Subversion's httpd servers are vulnerable to a remotely triggerable crash in the mod_authz_svn module. The crash can occur during an authorization check for a COPY or MOVE request with a specially crafted header value.
This allows remote attackers to cause a denial of service.

Squid security advisory 2016:5 reports:
Due to incorrect buffer management Squid cachemgr.cgi tool is vulnerable to a buffer overflow when processing remotely supplied inputs relayed to it from Squid.
This problem allows any client to seed the Squid manager reports with data that will cause a buffer overflow when processed by the cachemgr.cgi tool. However, this does require manual administrator actions to take place. Which greatly reduces the impact and possible uses.
Squid security advisory 2016:6 reports:
Due to buffer overflow issues Squid is vulnerable to a denial of service attack when processing ESI responses. Due to incorrect input validation Squid is vulnerable to public information disclosure of the server stack layout when processing ESI responses. Due to incorrect input validation and buffer overflow Squid is vulnerable to remote code execution when processing ESI responses.
These problems allow ESI components to be used to perform a denial of service attack on the Squid service and all other services on the same machine. Under certain build conditions these problems allow remote clients to view large sections of the server memory. However, the bugs are exploitable only if you have built and configured the ESI features to be used by a reverse-proxy and if the ESI components being processed by Squid can be controlled by an attacker.

MITRE reports:
The get_option function in dhcp.c in dhcpcd before 6.2.0, as used in dhcpcd 5.x in Android before 5.1 and other products, does not validate the relationship between length fields and the amount of data, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a large length value of an option in a DHCPACK message.
MITRE reports:
The print_option function in dhcp-common.c in dhcpcd through 6.9.1, as used in dhcp.c in dhcpcd 5.x in Android before 5.1 and other products, misinterprets the return value of the snprintf function, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted message.
The Asterisk project reports:
PJProject has a limit on the number of TCP connections that it can accept. Furthermore, PJProject does not close TCP connections it accepts. By default, this value is approximately 60.
An attacker can deplete the number of allowed TCP connections by opening TCP connections and sending no data to Asterisk.
If PJProject has been compiled in debug mode, then once the number of allowed TCP connections has been depleted, the next attempted TCP connection to Asterisk will crash due to an assertion in PJProject.
If PJProject has not been compiled in debug mode, then any further TCP connection attempts will be rejected. This makes Asterisk unable to process TCP SIP traffic.
Note that this only affects TCP/TLS, since UDP is connectionless.
The Asterisk project reports:
Asterisk may crash when processing an incoming REGISTER request if that REGISTER contains a Contact header with a lengthy URI.
This crash will only happen for requests that pass authentication. Unauthenticated REGISTER requests will not result in a crash occurring.
This vulnerability only affects Asterisk when using PJSIP as its SIP stack. The chan_sip module does not have this problem.
Jason Buberel reports:
Go has an infinite loop in several big integer routines that makes Go programs vulnerable to remote denial of service attacks. Programs using HTTPS client authentication or the Go ssh server libraries are both exposed to this vulnerability.
Samba team reports:
[CVE-2015-5370] Errors in Samba DCE-RPC code can lead to denial of service (crashes and high cpu consumption) and man in the middle attacks.
[CVE-2016-2110] The feature negotiation of NTLMSSP is not downgrade protected. A man in the middle is able to clear even required flags, especially NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL.
[CVE-2016-2111] When Samba is configured as Domain Controller it allows remote attackers to spoof the computer name of a secure channel's endpoints, and obtain sensitive session information, by running a crafted application and leveraging the ability to sniff network traffic.
[CVE-2016-2112] A man in the middle is able to downgrade LDAP connections to no integrity protection.
[CVE-2016-2113] Man in the middle attacks are possible for client triggered LDAP connections (with ldaps://) and ncacn_http connections (with https://).
[CVE-2016-2114] Due to a bug Samba doesn't enforce required smb signing, even if explicitly configured.
[CVE-2016-2115] The protection of DCERPC communication over ncacn_np (which is the default for most the file server related protocols) is inherited from the underlying SMB connection.
[CVE-2016-2118] a.k.a. BADLOCK. A man in the middle can intercept any DCERPC traffic between a client and a server in order to impersonate the client and get the same privileges as the authenticated user account. This is most problematic against active directory domain controllers.

Squid security advisory 2016:3 reports:
Due to a buffer overrun Squid pinger binary is vulnerable to denial of service or information leak attack when processing ICMPv6 packets.
This bug also permits the server response to manipulate other ICMP and ICMPv6 queries processing to cause information leak.
This bug allows any remote server to perform a denial of service attack on the Squid service by crashing the pinger. This may affect Squid HTTP routing decisions. In some configurations, sub-optimal routing decisions may result in serious service degradation or even transaction failures.
If the system does not contain buffer-overrun protection leading to that crash this bug will instead allow attackers to leak arbitrary amounts of information from the heap into Squid log files. This is of higher importance than usual because the pinger process operates with root priviliges.
Squid security advisory 2016:4 reports:
Due to incorrect bounds checking Squid is vulnerable to a denial of service attack when processing HTTP responses.
This problem allows a malicious client script and remote server delivering certain unusual HTTP response syntax to trigger a denial of service for all clients accessing the Squid service.
PostgreSQL project reports:
Security Fixes for RLS, BRIN
This release closes security hole CVE-2016-2193 (https://access.redhat.com/security/cve/CVE-2016-2193), where a query plan might get reused for more than one ROLE in the same session. This could cause the wrong set of Row Level Security (RLS) policies to be used for the query.
The update also fixes CVE-2016-3065 (https://access.redhat.com/security/cve/CVE-2016-3065), a server crash bug triggered by using `pageinspect` with BRIN index pages. Since an attacker might be able to expose a few bytes of server memory, this crash is being treated as a security issue.

The botan developers reports:
Infinite loop in modular square root algorithm - The ressol function implements the Tonelli-Shanks algorithm for finding square roots could be sent into a nearly infinite loop due to a misplaced conditional check. This could occur if a composite modulus is provided, as this algorithm is only defined for primes. This function is exposed to attacker controlled input via the OS2ECP function during ECC point decompression.
Heap overflow on invalid ECC point - The PointGFp constructor did not check that the affine coordinate arguments were less than the prime, but then in curve multiplication assumed that both arguments if multiplied would fit into an integer twice the size of the prime.
The bigint_mul and bigint_sqr functions received the size of the output buffer, but only used it to dispatch to a faster algorithm in cases where there was sufficient output space to call an unrolled multiplication function.
The result is a heap overflow accessible via ECC point decoding, which accepted untrusted inputs. This is likely exploitable for remote code execution.
On systems which use the mlock pool allocator, it would allow an attacker to overwrite memory held in secure_vector objects. After this point the write will hit the guard page at the end of the mmapped region so it probably could not be used for code execution directly, but would allow overwriting adjacent key material.
The botan developers reports:
Excess memory allocation in BER decoder - The BER decoder would allocate a fairly arbitrary amount of memory in a length field, even if there was no chance the read request would succeed. This might cause the process to run out of memory or invoke the OOM killer.
Crash in BER decoder - The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. This can be used to easily crash applications reading untrusted ASN.1 data, but does not seem exploitable for code execution.

Alvaro Muatoz, Matthias Kaiser and Christian Schneider reports:
JMS Object messages depends on Java Serialization for marshaling/unmashaling of the message payload. There are a couple of places inside the broker where deserialization can occur, like web console or stomp object message transformation. As deserialization of untrusted data can lead to security flaws as demonstrated in various reports, this leaves the broker vulnerable to this attack vector. Additionally, applications that consume ObjectMessage type of messages can be vulnerable as they deserialize objects on ObjectMessage.getObject() calls.
Michael Furman reports:
The web based administration console does not set the X-Frame-Options header in HTTP responses. This allows the console to be embedded in a frame or iframe which could then be used to cause a user to perform an unintended action in the console.

The OpenSSH project reports:
Missing sanitisation of untrusted input allows an authenticated user who is able to request X11 forwarding to inject commands to xauth(1).
Injection of xauth commands grants the ability to read arbitrary files under the authenticated user's privilege, Other xauth commands allow limited information leakage, file overwrite, port probing and generally expose xauth(1), which was not written with a hostile user in mind, as an attack surface.
Mitigation:
Set X11Forwarding=no in sshd_config. This is the default.
For authorized_keys that specify a "command" restriction, also set the "restrict" (available in OpenSSH >=7.2) or "no-x11-forwarding" restrictions.

Mozilla Foundation reports:
Security researcher Holger Fuhrmannek and Mozilla security engineer Tyson Smith reported a number of security vulnerabilities in the Graphite 2 library affecting version 1.3.5. The issue reported by Holger Fuhrmannek is a mechanism to induce stack corruption with a malicious graphite font. This leads to a potentially exploitable crash when the font is loaded. Tyson Smith used the Address Sanitizer tool in concert with a custom software fuzzer to find a series of uninitialized memory, out-of-bounds read, and out-of-bounds write errors when working with fuzzed graphite fonts.
Security researcher James Clawson used the Address Sanitizer tool to discover an out-of-bounds write in the Graphite 2 library when loading a crafted Graphite font file. This results in a potentially exploitable crash.
Mozilla Foundation reports:
Security researcher Francis Gabriel reported a heap-based buffer overflow in the way the Network Security Services (NSS) libraries parsed certain ASN.1 structures. An attacker could create a specially-crafted certificate which, when parsed by NSS, would cause it to crash or execute arbitrary code with the permissions of the user.
Mozilla developer Tim Taubert used the Address Sanitizer tool and software fuzzing to discover a use-after-free vulnerability while processing DER encoded keys in the Network Security Services (NSS) libraries. The vulnerability overwrites the freed memory with zeroes.
Mozilla Foundation reports:
Security researcher Hanno Böck reported that calculations with mp_div and mp_exptmod in Network Security Services (NSS) can produce wrong results in some circumstances. These functions are used within NSS for a variety of cryptographic division functions, leading to potential cryptographic weaknesses.

Andreas Schneider reports:
libssh versions 0.1 and above have a bits/bytes confusion bug and generate an abnormally short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 1024 and 2048 bits respectively. There are practical algorithms (Baby steps/Giant steps, Pollard’s rho) that can solve this problem in O(2^63) operations.
Both client and server are are vulnerable, pre-authentication. This vulnerability could be exploited by an eavesdropper with enough resources to decrypt or intercept SSH sessions. The bug was found during an internal code review by Aris Adamantiadis of the libssh team.
The Exim development team reports:
All installations having Exim set-uid root and using 'perl_startup' are vulnerable to a local privilege escalation. Any user who can start an instance of Exim (and this is normally any user) can gain root privileges. If you do not use 'perl_startup' you should be safe.

The Apache Software Foundation reports:
The Xerces-C XML parser mishandles certain kinds of malformed input documents, resulting in buffer overflows during processing and error reporting. The overflows can manifest as a segmentation fault or as memory corruption during a parse operation. The bugs allow for a denial of service attack in many applications by an unauthenticated attacker, and could conceivably result in remote code execution.
Tim Graham reports:
User with "change" but not "add" permission can create objects for ModelAdmin’s with save_as=True
The Xen Project reports:
VMX refuses attempts to enter a guest with an instruction pointer which doesn't satisfy certain requirements. In particular, the instruction pointer needs to be canonical when entering a guest currently in 64-bit mode. This is the case even if the VM entry information specifies an exception to be injected immediately (in which case the bad instruction pointer would possibly never get used for other than pushing onto the exception handler's stack). Provided the guest OS allows user mode to map the virtual memory space immediately below the canonical/non-canonical address boundary, a non-canonical instruction pointer can result even from normal user mode execution. VM entry failure, however, is fatal to the guest.
Malicious HVM guest user mode code may be able to crash the guest.
The Xen Project reports:
While INVLPG does not cause a General Protection Fault when used on a non-canonical address, INVVPID in its "individual address" variant, which is used to back the intercepted INVLPG in certain cases, fails in such cases. Failure of INVVPID results in a hypervisor bug check.
A malicious guest can crash the host, leading to a Denial of Service.
The Xen Project reports:
The PV superpage functionality lacks certain validity checks on data being passed to the hypervisor by guests. This is the case for the page identifier (MFN) passed to MMUEXT_MARK_SUPER and MMUEXT_UNMARK_SUPER sub-ops of the HYPERVISOR_mmuext_op hypercall as well as for various forms of page table updates.
Use of the feature, which is disabled by default, may have unknown effects, ranging from information leaks through Denial of Service to privilege escalation.

Jenkins Security Advisory:
Description
SECURITY-232 / CVE-2016-0788(Remote code execution vulnerability in remoting module)
A vulnerability in the Jenkins remoting module allowed unauthenticated remote attackers to open a JRMP listener on the server hosting the Jenkins master process, which allowed arbitrary code execution.
SECURITY-238 / CVE-2016-0789(HTTP response splitting vulnerability)
An HTTP response splitting vulnerability in the CLI command documentation allowed attackers to craft Jenkins URLs that serve malicious content.
SECURITY-241 / CVE-2016-0790(Non-constant time comparison of API token)
The verification of user-provided API tokens with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid API tokens using brute-force methods.
SECURITY-245 / CVE-2016-0791(Non-constant time comparison of CSRF crumbs)
The verification of user-provided CSRF crumbs with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid CSRF crumbs using brute-force methods.
SECURITY-247 / CVE-2016-0792(Remote code execution through remote API)
Jenkins has several API endpoints that allow low-privilege users to POST XML files that then get deserialized by Jenkins. Maliciously crafted XML files sent to these API endpoints could result in arbitrary code execution.
Squid security advisory 2016:2 reports:
Due to incorrect bounds checking Squid is vulnerable to a denial of service attack when processing HTTP responses.
These problems allow remote servers delivering certain unusual HTTP response syntax to trigger a denial of service for all clients accessing the Squid service.
HTTP responses containing malformed headers that trigger this issue are becoming common. We are not certain at this time if that is a sign of malware or just broken server scripting.
Stian Soiland-Reyes reports:
This release fixes a remote code execution vulnerability that was identified in BeanShell by Alvaro Muñoz and Christian Schneider. The BeanShell team would like to thank them for their help and contributions to this fix!
An application that includes BeanShell on the classpath may be vulnerable if another part of the application uses Java serialization or XStream to deserialize data from an untrusted source.
A vulnerable application could be exploited for remote code execution, including executing arbitrary shell commands.
This update fixes the vulnerability in BeanShell, but it is worth noting that applications doing such deserialization might still be insecure through other libraries. It is recommended that application developers take further measures such as using a restricted class loader when deserializing. See notes on Java serialization security XStream security and How to secure deserialization from untrusted input without using encryption or sealing.
libsrtp reports:
Prevent potential DoS attack due to lack of bounds checking on RTP header CSRC count and extension header length. Credit goes to Randell Jesup and the Firefox team for reporting this issue.
oCERT reports:
The library is affected by a double-free vulnerability in function jas_iccattrval_destroy() as well as a heap-based buffer overflow in function jp2_decode(). A specially crafted jp2 file can be used to trigger the vulnerabilities.
oCERT reports:
The library is affected by an off-by-one error in a buffer boundary check in jpc_dec_process_sot(), leading to a heap based buffer overflow, as well as multiple unrestricted stack memory use issues in jpc_qmfb.c, leading to stack overflow. A specially crafted jp2 file can be used to trigger the vulnerabilities.
oCERT reports:
Multiple off-by-one flaws, leading to heap-based buffer overflows, were found in the way JasPer decoded JPEG 2000 files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code.
limingxing reports:
A vulnerability was found in the way the JasPer's jas_matrix_clip() function parses certain JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.
Google Chrome Releases reports:
[583431] Critical CVE-2016-1629: Same-origin bypass in Blink and Sandbox escape in Chrome. Credit to anonymous.
Fabio Olive Leite reports:
A stack-based buffer overflow was found in libresolv when invoked from nss_dns, allowing specially crafted DNS responses to seize control of EIP in the DNS client. The buffer overflow occurs in the functions send_dg (send datagram) and send_vc (send TCP) for the NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC family, or in some cases AF_INET6 family. The use of AF_UNSPEC (or AF_INET6 in some cases) triggers the low-level resolver code to send out two parallel queries for A and AAAA. A mismanagement of the buffers used for those queries could result in the response of a query writing beyond the alloca allocated buffer created by __res_nquery.
Squid security advisory 2016:1 reports:
Due to incorrectly handling server errors Squid is vulnerable to a denial of service attack when connecting to TLS or SSL servers.
This problem allows any trusted client to perform a denial of service attack on the Squid service regardless of whether TLS or SSL is configured for use in the proxy.
Misconfigured client or server software may trigger this issue to perform a denial of service unintentionally.
However, the bug is exploitable only if Squid is built using the --with-openssl option.
The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

The Mozilla Foundation reports:
MFSA 2016-13 Jason Pang of OneSignal reported that service workers intercept responses to plugin network requests made through the browser. Plugins which make security decisions based on the content of network requests can have these decisions subverted if a service worker forges responses to those requests. For example, a forged crossdomain.xml could allow a malicious site to violate the same-origin policy using the Flash plugin.
Nghttp2 reports:
Out of memory in nghttpd, nghttp, and libnghttp2_asio applications due to unlimited incoming HTTP header fields.
nghttpd, nghttp, and libnghttp2_asio applications do not limit the memory usage for the incoming HTTP header field. If peer sends specially crafted HTTP/2 HEADERS frames and CONTINUATION frames, they will crash with out of memory error.
Note that libnghttp2 itself is not affected by this vulnerability.

The Pillow maintainers report:
In all versions of Pillow, dating back at least to the last PIL 1.1.7 release, PcdDecode.c has a buffer overflow error.
The state.buffer for PcdDecode.c is allocated based on a 3 bytes per pixel sizing, where PcdDecode.c wrote into the buffer assuming 4 bytes per pixel. This writes 768 bytes beyond the end of the buffer into other Python object storage. In some cases, this causes a segfault, in others an internal Python malloc error.
The Pillow maintainers report:
If a large value was passed into the new size for an image, it is possible to overflow an int32 value passed into malloc, leading the malloc’d buffer to be undersized. These allocations are followed by a loop that writes out of bounds. This can lead to corruption on the heap of the Python process with attacker controlled float data.
This issue was found by Ned Williamson.
The Pillow maintainers report:
In all versions of Pillow, dating back at least to the last PIL 1.1.7 release, FliDecode.c has a buffer overflow error.
There is a memcpy error where x is added to a target buffer address. X is used in several internal temporary variable roles, but can take a value up to the width of the image. Im->image[y] is a set of row pointers to segments of memory that are the size of the row. At the max y, this will write the contents of the line off the end of the memory buffer, causing a segfault.
This issue was found by Alyssa Besseling at Atlassian.
The Pillow maintainers report:
Pillow 3.1.0 and earlier when linked against libtiff >= 4.0.0 on x64 may overflow a buffer when reading a specially crafted tiff file.
Specifically, libtiff >= 4.0.0 changed the return type of TIFFScanlineSize from int32 to machine dependent int32|64. If the scanline is sized so that it overflows an int32, it may be interpreted as a negative number, which will then pass the size check in TiffDecode.c line 236. To do this, the logical scanline size has to be > 2gb, and for the test file, the allocated buffer size is 64k against a roughly 4gb scan line size. Any image data over 64k is written over the heap, causing a segfault.
This issue was found by security researcher FourOne.
FFmpeg security reports:
FFmpeg 2.8.6 fixes the following vulnerabilities: CVE-2016-2213
Michael Catanzaro reports:
Shotwell has a serious security issue ("Shotwell does not verify TLS certificates"). Upstream is no longer active and I do not expect any further upstream releases unless someone from the community steps up to maintain it.
What is the impact of the issue? If you ever used any of the publish functionality (publish to Facebook, publish to Flickr, etc.), your passwords may have been stolen; changing them is not a bad idea.
What is the risk of the update? Regressions. The easiest way to validate TLS certificates was to upgrade WebKit; it seems to work but I don't have accounts with the online services it supports, so I don't know if photo publishing still works properly on all the services.

socat reports:
In the OpenSSL address implementation the hard coded 1024 bit DH p parameter was not prime. The effective cryptographic strength of a key exchange using these parameters was weaker than the one one could get by using a prime p. Moreover, since there is no indication of how these parameters were chosen, the existence of a trapdoor that makes possible for an eavesdropper to recover the shared secret from a key exchange that uses them cannot be ruled out.

The Prosody team reports:
Adopt key generation algorithm from XEP-0185, to prevent impersonation attacks (CVE-2016-0756)
OpenSSL project reports:
- Historically OpenSSL only ever generated DH parameters based on "safe" primes. More recently (in version 1.0.2) support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be "safe". Where an application is using DH configured with parameters based on primes that are not "safe" then an attacker could use this fact to find a peer's private DH exponent. This attack requires that the attacker complete multiple handshakes in which the peer uses the same private DH exponent. For example this could be used to discover a TLS server's private DH exponent if it's reusing the private DH exponent or it's using a static DH ciphersuite. OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in TLS. It is not on by default. If the option is not set then the server reuses the same private DH exponent for the life of the server process and would be vulnerable to this attack. It is believed that many popular applications do set this option and would therefore not be at risk. (CVE-2016-0701)
- A malicious client can negotiate SSLv2 ciphers that have been disabled on the server and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled, provided that the SSLv2 protocol was not also disabled via SSL_OP_NO_SSLv2. (CVE-2015-3197)

Jason Buberel reports:
A security-related issue has been reported in Go's math/big package. The issue was introduced in Go 1.5. We recommend that all users upgrade to Go 1.5.3, which fixes the issue. Go programs must be recompiled with Go 1.5.3 in order to receive the fix.
The Go team would like to thank Nick Craig-Wood for identifying the issue.
This issue can affect RSA computations in crypto/rsa, which is used by crypto/tls. TLS servers on 32-bit systems could plausibly leak their RSA private key due to this issue. Other protocol implementations that create many RSA signatures could also be impacted in the same way.
Specifically, incorrect results in one part of the RSA Chinese Remainder computation can cause the result to be incorrect in such a way that it leaks one of the primes. While RSA blinding should prevent an attacker from crafting specific inputs that trigger the bug, on 32-bit systems the bug can be expected to occur at random around one in 2^26 times. Thus collecting around 64 million signatures (of known data) from an affected server should be enough to extract the private key used.
On 64-bit systems, the frequency of the bug is so low (less than one in 2^50) that it would be very difficult to exploit. Nonetheless, everyone is strongly encouraged to upgrade.

MD5 handshake signatures in TLS 1.2 are vulnerable to the SLOTH attack on TLS 1.2 server authentication. They have been disabled by default. Other attacks from the SLOTH paper do not apply to any version of mbed TLS or PolarSSL.
The Xen Project reports:
Single memory accesses in source code can be translated to multiple ones in machine code by the compiler, requiring special caution when accessing shared memory. Such precaution was missing from the hypervisor code inspecting the state of I/O requests sent to the device model for assistance.
Due to the offending field being a bitfield, it is however believed that there is no issue in practice, since compilers, at least when optimizing (which is always the case for non-debug builds), should find it more expensive to extract the bit field value twice than to keep the calculated value in a register.
This vulnerability is exposed to malicious device models. In conventional Xen systems this means the qemu which service an HVM domain. On such systems this vulnerability can only be exploited if the attacker has gained control of the device model qemu via another vulnerability.
Privilege escalation, host crash (Denial of Service), and leaked information all cannot be excluded.
The Xen Project reports:
When XSAVE/XRSTOR are not in use by Xen to manage guest extended register state, the initial values in the FPU stack and XMM registers seen by the guest upon first use are those left there by the previous user of those registers.
A malicious domain may be able to leverage this to obtain sensitive information such as cryptographic keys from another domain.
The Xen Project reports:
When constructing a guest which is configured to use a PV bootloader which runs as a userspace process in the toolstack domain (e.g. pygrub) libxl creates a mapping of the files to be used as kernel and initial ramdisk when building the guest domain.
However if building the domain subsequently fails these mappings would not be released leading to a leak of virtual address space in the calling process, as well as preventing the recovery of the temporary disk files containing the kernel and initial ramdisk.
For toolstacks which manage multiple domains within the same process, an attacker who is able to repeatedly start a suitable domain (or many such domains) can cause an out-of-memory condition in the toolstack process, leading to a denial of service.
Under the same circumstances an attacker can also cause files to accumulate on the toolstack domain filesystem (usually under /var in dom0) used to temporarily store the kernel and initial ramdisk, perhaps leading to a denial of service against arbitrary other services using that filesystem.
The Xen Project reports:
Error handling in the operation may involve handing back pages to the domain. This operation may fail when in parallel the domain gets torn down. So far this failure unconditionally resulted in the host being brought down due to an internal error being assumed. This is CVE-2015-8339.
Furthermore error handling so far wrongly included the release of a lock. That lock, however, was either not acquired or already released on all paths leading to the error handling sequence. This is CVE-2015-8340.
A malicious guest administrator may be able to deny service by crashing the host or causing a deadlock.

SQL injection vulnerability in include/top_graph_header.php in Cacti 0.8.8f and earlier allows remote attackers to execute arbitrary SQL commands via the rra_id parameter in a properties action to graph.php.
ISC Support reports:
ISC Kea may terminate unexpectedly (crash) while handling a malformed client packet. Related defects in the kea-dhcp4 and kea-dhcp6 servers can cause the server to crash during option processing if a client sends a malformed packet. An attacker sending a crafted malformed packet can cause an ISC Kea server providing DHCP services to IPv4 or IPv6 clients to exit unexpectedly.
The kea-dhcp4 server is vulnerable only in versions 0.9.2 and 1.0.0-beta, and furthermore only when logging at debug level 40 or higher. Servers running kea-dhcp4 versions 0.9.1 or lower, and servers which are not logging or are logging at debug level 39 or below are not vulnerable.
The kea-dhcp6 server is vulnerable only in versions 0.9.2 and 1.0.0-beta, and furthermore only when logging at debug level 45 or higher. Servers running kea-dhcp6 versions 0.9.1 or lower, and servers which are not logging or are logging at debug level 44 or below are not vulnerable.

Petr Matousek of Red Hat Inc. reports:
Due converting PIO to the new memory read/write api we no longer provide separate I/O region lenghts for read and write operations. As a result, reading from PIT Mode/Command register will end with accessing pit->channels with invalid index and potentially cause memory corruption and/or minor information leak.
A privileged guest user in a guest with QEMU PIT emulation enabled could potentially (tough unlikely) use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process.
Please note that by default QEMU/KVM guests use in-kernel (KVM) PIT emulation and are thus not vulnerable to this issue.

NVD reports:
The ff_dwt_decode function in libavcodec/jpeg2000dwt.c in FFmpeg before 2.8.4 does not validate the number of decomposition levels before proceeding with Discrete Wavelet Transform decoding, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.
The ff_get_buffer function in libavcodec/utils.c in FFmpeg before 2.8.4 preserves width and height values after a failure, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted .mov file.
The Mozilla Project reports:
Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services (NSS) where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the accepting MD5 as a hash algorithm in signatures since 2011. This issues exposes NSS based clients such as Firefox to theoretical collision-based forgery attacks.
The phpMyAdmin development team reports:
By calling some scripts that are part of phpMyAdmin in an unexpected way, it is possible to trigger phpMyAdmin to display a PHP error message which contains the full path of the directory where phpMyAdmin is installed.
We consider these vulnerabilities to be non-critical.
This path disclosure is possible on servers where the recommended setting of the PHP configuration directive display_errors is set to on, which is against the recommendations given in the PHP manual for a production server.
Salvatore Bonaccorso reports:
Hanno Boeck discovered a stack-based buffer overflow in the dpkg-deb component of dpkg, the Debian package management system. This flaw could potentially lead to arbitrary code execution if a user or an automated system were tricked into processing a specially crafted Debian binary package (.deb) in the old style Debian binary package format.

Bugzilla Security Advisory
During the generation of a dependency graph, the code for the HTML image map is generated locally if a local dot installation is used. With escaped HTML characters in a bug summary, it is possible to inject unfiltered HTML code in the map file which the CreateImagemap function generates. This could be used for a cross-site scripting attack.
If an external HTML page contains a <script> element with its src attribute pointing to a buglist in CSV format, some web browsers incorrectly try to parse the CSV file as valid JavaScript code. As the buglist is generated based on the privileges of the user logged into Bugzilla, the external page could collect confidential data contained in the CSV file.

Pierre Schweitzer reports:
Any client sending the command "/op *" in a query will cause the Quassel core to crash.
Libvit development team reports:
Various virStorageVol* API operate on user-supplied volume names by concatenating the volume name to the pool location. Note that the virStoragePoolListVolumes API, when used on a storage pool backed by a directory in a file system, will only list volumes immediately in that directory (there is no traversal into subdirectories). However, other APIs such as virStorageVolCreateXML were not checking if a potential volume name represented one of the volumes that could be returned by virStoragePoolListVolumes; because they were not rejecting the use of '/' in a volume name.
Because no checking was done on volume names, a user could supply a potential volume name of something like '../../../etc/passwd' to attempt to access a file not belonging to the storage pool. When fine-grained Access Control Lists (ACL) are in effect, a user with storage_vol:create ACL permission but lacking domain:write permission could thus abuse virStorageVolCreateXML and similar APIs to gain access to files not normally permitted to that user. Fortunately, it appears that the only APIs that could leak information or corrupt files require read-write connection to libvirtd; and when ACLs are not in use (the default without any further configuration), a user with read-write access can already be considered to have full access to the machine, and without an escalation of privilege there is no security problem.

Jenkins Security Advisory:
Description
SECURITY-95 / CVE-2015-7536 (Stored XSS vulnerability through workspace files and archived artifacts)
In certain configurations, low privilege users were able to create e.g. HTML files in workspaces and archived artifacts that could result in XSS when accessed by other users. Jenkins now sends Content-Security-Policy headers that enables sandboxing and prohibits script execution by default.
SECURITY-225 / CVE-2015-7537 (CSRF vulnerability in some administrative actions)
Several administration/configuration related URLs could be accessed using GET, which allowed attackers to circumvent CSRF protection.
SECURITY-233 / CVE-2015-7538 (CSRF protection ineffective)
Malicious users were able to circumvent CSRF protection on any URL by sending specially crafted POST requests.
SECURITY-234 / CVE-2015-7539 (Jenkins plugin manager vulnerable to MITM attacks)
While the Jenkins update site data is digitally signed, and the signature verified by Jenkins, Jenkins did not verify the provided SHA-1 checksums for the plugin files referenced in the update site data. This enabled MITM attacks on the plugin manager, resulting in installation of attacker-provided plugins.

Daniel Knoppel reports:
It was discovered by the SUSE security team that it was possible, in some cases, for clients to overwrite headers set by the server, resulting in a medium level security issue. CVE-2015-7519 has been assigned to this issue.
Affected use-cases:
Header overwriting may occur if all of the following conditions are met:
- Apache integration mode, or standalone+builtin engine without a filtering proxy
- Ruby or Python applications only (Passenger 5); or any application (Passenger 4)
- The app depends on a request header containing a dash (-)
- The header is supposed to be trusted (set by the server)
- The client correctly guesses the header name
This vulnerability has been fixed by filtering out client headers that do not consist of alphanumeric/dash characters (Nginx already did this, so Passenger+Nginx was not affected). If your application depends on headers that don't conform to this, you can add a workaround in Apache specifically for those to convert them to a dash-based format.

NVD reports:
The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file.
The ljpeg_decode_yuv_scan function in libavcodec/mjpegdec.c in FFmpeg before 2.8.2 omits certain width and height checks, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted MJPEG data.
The ff_hevc_parse_sps function in libavcodec/hevc_ps.c in FFmpeg before 2.8.2 does not validate the Chroma Format Indicator, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted High Efficiency Video Coding (HEVC) data.
The decode_uncompressed function in libavcodec/faxcompr.c in FFmpeg before 2.8.2 does not validate uncompressed runs, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted CCITT FAX data.
The init_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.2 does not enforce minimum-value and maximum-value constraints on tile coordinates, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.
The jpeg2000_read_main_headers function in libavcodec/jpeg2000dec.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not enforce uniqueness of the SIZ marker in a JPEG 2000 image, which allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via a crafted image with two or more of these markers.
Integer overflow in the ff_ivi_init_planes function in libavcodec/ivi.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via crafted image dimensions in Indeo Video Interactive data.
The smka_decode_frame function in libavcodec/smacker.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not verify that the data size is consistent with the number of channels, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Smacker data.

The Xen Project reports:
A malicious HVM guest administrator can cause a denial of service. Specifically, prevent use of a physical CPU for a significant, perhaps indefinite period. If a host watchdog (Xen or dom0) is in use, this can lead to a watchdog timeout and consequently a reboot of the host. If another, innocent, guest, is configured with a watchdog, this issue can lead to a reboot of such a guest.
libpng reports:
CVE for a vulnerability in libpng, all versions, in the png_set_PLTE/png_get_PLTE functions. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bit_depth less than 8. Some applications might read the bit depth from the IHDR chunk and allocate memory for a 2^N entry palette, while libpng can return a palette with up to 256 entries even when the bit depth is less than 8.

Jenkins Developers report:
Unsafe deserialization allows unauthenticated remote attackers to run arbitrary code on the Jenkins master.
owncloud.org reports:
The ownCloud Desktop Client was vulnerable against MITM attacks until version 2.0.0 in combination with self-signed certificates.
The Xen Project reports:
Guests configured with PoD might be unstable, especially under load. In an affected guest, an unprivileged guest user might be able to cause a guest crash, perhaps simply by applying load so as to cause heavy memory pressure within the guest.
The Xen Project reports:
HYPERCALL_xenoprof_op and HYPERVISOR_xenpmu_op log some errors and attempts at invalid operations. These log messages are not rate-limited, even though they can be triggered by guests.
A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.
The Xen Project reports:
A domain's xenoprofile state contains an array of per-vcpu information... This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory.
The following parties can mount a denial of service attack affecting the whole system:
- A malicious guest administrator via XENOPROF_get_buffer.
- A domain given suitable privilege over another domain via XENOPROF_set_passive (this would usually be a domain being used to profile another domain, eg with the xenoprof tool).
The ability to also restart or create suitable domains is also required to fully exploit the issue. Without this the leak is limited to a small multiple of the maximum number of vcpus for the domain.
The Xen Project reports:
When running an HVM domain in Populate-on-Demand mode, Xen would sometimes search the domain for memory to reclaim, in response to demands for population of other pages in the same domain. This search runs without preemption. The guest can, by suitable arrangement of its memory contents, create a situation where this search is a time-consuming linear scan of the guest's address space.
A malicious HVM guest administrator can cause a denial of service. Specifically, prevent use of a physical CPU for a significant period.
The Xen Project reports:
A domain's primary array of vcpu pointers can be allocated by a toolstack exactly once in the lifetime of a domain via the XEN_DOMCTL_max_vcpus hypercall. This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory.
A domain given partial management control via XEN_DOMCTL_max_vcpus can mount a denial of service attack affecting the whole system. The ability to also restart or create suitable domains is also required to fully exploit the issue. Without this the leak is limited to a small multiple of the maximum number of vcpus for the domain. The maximum leak is 64kbytes per domain (re)boot (less on ARM).
The Xen Project reports:
The code to validate level 2 page table entries is bypassed when certain conditions are satisfied. This means that a PV guest can create writable mappings using super page mappings. Such writable mappings can violate Xen intended invariants for pages which Xen is supposed to keep read-only. This is possible even if the "allowsuperpage" command line option is not used.
Malicious PV guest administrators can escalate privilege so as to control the whole system.
The Xen Project reports:
Callers of libxl can specify that a disk should be read-only to the guest. However, there is no code in libxl to pass this information to qemu-xen (the upstream-based qemu); and indeed there is no way in qemu to make a disk read-only.
The vulnerability is exploitable only via devices emulated by the device model, not the parallel PV devices for supporting PVHVM. Normally the PVHVM device unplug protocol renders the emulated devices inaccessible early in boot.
Malicious guest administrators or (in some situations) users may be able to write to supposedly read-only disk images.
CDROM devices (that is, devices specified to be presented to the guest as CDROMs, regardless of the nature of the backing storage on the host) are not affected.
MITRE reports:
Cross-site scripting (XSS) vulnerability in the HTML-Scrubber module before 0.15 for Perl, when the comment feature is enabled, allows remote attackers to inject arbitrary web script or HTML via a crafted comment.
The Mozilla Project reports:
Security researcher Khalil Zhani reported that a maliciously crafted vp9 format video could be used to trigger a buffer overflow while parsing the file. This leads to a potentially exploitable crash due to a flaw in the libvpx library.
PowerDNS reports:
A bug was found using afl-fuzz in our packet parsing code. This bug, when exploited, causes an assertion error and consequent termination of the the pdns_server process, causing a Denial of Service.
Ben Harris reports:
Versions of PuTTY and pterm between 0.54 and 0.65 inclusive have a potentially memory-corrupting integer overflow in the handling of the ECH (erase characters) control sequence in the terminal emulator.
To exploit a vulnerability in the terminal emulator, an attacker must be able to insert a carefully crafted escape sequence into the terminal stream. For a PuTTY SSH session, this must be before encryption, so the attacker likely needs access to the server you're connecting to. For instance, an attacker on a multi-user machine that you connect to could trick you into running cat on a file they control containing a malicious escape sequence. (Unix write(1) is not a vector for this, if implemented correctly.)
Only PuTTY, PuTTYtel, and pterm are affected; other PuTTY tools do not include the terminal emulator, so cannot be exploited this way.
The Apache OpenOffice Project reports:
A vulnerability in OpenOffice settings of OpenDocument Format files and templates allows silent access to files that are readable from an user account, over-riding the user's default configuration settings. Once these files are imported into a maliciously-crafted document, the data can be silently hidden in the document and possibly exported to an external party without being observed.
The Apache OpenOffice Project reports:
A crafted ODF document can be used to create a buffer that is too small for the amount of data loaded into it, allowing an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.
The Apache OpenOffice Project reports:
A crafted Microsoft Word DOC file can be used to specify a document buffer that is too small for the amount of data provided for it. Failure to detect the discrepancy allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.
The Apache OpenOffice Project reports:
A crafted Microsoft Word DOC can contain invalid bookmark positions leading to memory corruption when the document is loaded or bookmarks are manipulated. The defect allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.
The CodeIgniter changelog reports:
Fixed an XSS attack vector in Security Library method xss_clean().
Changed Config Library method base_url() to fallback to ``$_SERVER['SERVER_ADDR']`` in order to avoid Host header injections.
Changed CAPTCHA Helper to try to use the operating system's PRNG first.
The OpenAFS development team reports:
When constructing an Rx acknowledgment (ACK) packet, Andrew-derived Rx implementations do not initialize three octets of data that are padding in the C language structure and were inadvertently included in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0 through 1.7.32 include a variable-length padding at the end of the ACK packet, in an attempt to detect the path MTU, but only four octets of the additional padding are initialized (CVE-2015-7763).
RedHat bugzilla reports:
In dual screen configurations, unplugging one screen will cause xscreensaver to crash, leaving the screen unlocked.
The lldpd developer Vincent Bernat reports:
A buffer overflow may allow arbitrary code execution only if hardening was disabled.
Malformed packets should not make lldpd crash. Ensure we can handle them by not using assert() in this part.

Drupal development team reports:
The Overlay module in Drupal core displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module does not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability.
This vulnerability is mitigated by the fact that it can only be used against site users who have the "Access the administrative overlay" permission, and that the Overlay module must be enabled.
An incomplete fix for this issue was released as part of SA-CORE-2015-002.
The phpMyAdmin development team reports:
This vulnerability allows an attacker to perform a content spoofing attack using the phpMyAdmin's redirection mechanism to external sites.
We consider this vulnerability to be non critical since the spoofed content is escaped and no HTML injection is possible.
MediaWiki reports:
Wikipedia user RobinHood70 reported two issues in the chunked upload API. The API failed to correctly stop adding new chunks to the upload when the reported size was exceeded (T91203), allowing a malicious users to upload add an infinite number of chunks for a single file upload. Additionally, a malicious user could upload chunks of 1 byte for very large files, potentially creating a very large number of files on the server's filesystem (T91205).
Internal review discovered that it is not possible to throttle file uploads.
Internal review discovered a missing authorization check when removing suppression from a revision. This allowed users with the 'viewsuppressed' user right but not the appropriate 'suppressrevision' user right to unsuppress revisions.
Richard Stanway from teamliquid.net reported that thumbnails of PNG files generated with ImageMagick contained the local file path in the image metadata.
ntp.org reports:

Git release notes:
Some protocols (like git-remote-ext) can execute arbitrary code found in the URL. The URLs that submodules use may come from arbitrary sources (e.g., .gitmodules files in a remote repository), and can hurt those who blindly enable recursive fetch. Restrict the allowed protocols to well known and safe ones.
Salt release notes:
CVE-2015-6918 - Git modules leaking HTTPS auth credentials to debug log
Updated the Git state and execution modules to no longer display HTTPS basic authentication credentials in loglevel debug output on the Salt master. These credentials are now replaced with REDACTED in the debug output. Thanks to Andreas Stieger for bringing this to our attention.
CVE-2015-6941 - win_useradd module and salt-cloud display passwords in debug log
Updated the win_useradd module return data to no longer include the password of the newly created user. The password is now replaced with the string XXX-REDACTED-XXX. Updated the Salt Cloud debug output to no longer display win_password and sudo_password authentication credentials. Also updated the Linode driver to no longer display authentication credentials in debug logs. These credentials are now replaced with REDACTED in the debug output.
Firefox Developers report:
Security researcher Abdulrahman Alqabandi reported that the fetch() API did not correctly implement the Cross-Origin Resource Sharing (CORS) specification, allowing a malicious page to access private data from other origins. Mozilla developer Ben Kelly independently reported the same issue.
Adobe reports:
These updates resolve type confusion vulnerabilities that could lead to code execution (CVE-2015-7645, CVE-2015-7647, CVE-2015-7648).
Qualys reports:
During the code review of OpenSMTPD a memory leak and buffer overflow (an off-by-one, usually stack-based) were discovered in LibreSSL's OBJ_obj2txt() function. This function is called automatically during a TLS handshake (both client-side, unless an anonymous mode is used, and server-side, if client authentication is requested).
ARM Limited reports:
When the client creates its ClientHello message, due to insufficient bounds checking it can overflow the heap-based buffer containing the message while writing some extensions. Two extensions in particular could be used by a remote attacker to trigger the overflow: the session ticket extension and the server name indication (SNI) extension.

Matthijs Kooijman reports:
It seems that the whiptail, cdialog and kdialog backends apply some improper escaping in their shell commands, causing special characters present in menu item titles to be interpreted by the shell. This includes the backtick evaluation operator, so this constitutes a security issue, allowing execution of arbitrary commands if an attacker has control over the text displayed in a menu.
Matthias Bussonnier reports:
Summary: Local folder name was used in HTML templates without escaping, allowing XSS in said pages by carefully crafting folder name and URL to access it.

PostgreSQL project reports:
Two security issues have been fixed in this release which affect users of specific PostgreSQL features.
- CVE-2015-5289 json or jsonb input values constructed from arbitrary user input can crash the PostgreSQL server and cause a denial of service.
- CVE-2015-5288: The crypt() function included with the optional pgCrypto extension could be exploited to read a few additional bytes of memory. No working exploit for this issue has been developed.
Zend Framework developers report:
The PDO adapters of Zend Framework 1 do not filter null bytes values in SQL statements. A PDO adapter can treat null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection.
OpenSMTPD developers report:
fix an mda buffer truncation bug which allows a user to create forward files that pass session checks but fail delivery later down the chain, within the user mda
fix remote buffer overflow in unprivileged pony process
reworked offline enqueue to better protect against hardlink attacks
ARM Limited reports:
Florian Weimar from Red Hat published on Lenstra's RSA-CRT attach for PKCS#1 v1.5 signatures. These releases include countermeasures against that attack.
Fabian Foerg of Gotham Digital Science found a possible client-side NULL pointer dereference, using the AFL Fuzzer. This dereference can only occur when misusing the API, although a fix has still been implemented.
ARM Limited reports:
In order to strengthen the minimum requirements for connections and to protect against the Logjam attack, the minimum size of Diffie-Hellman parameters accepted by the client has been increased to 1024 bits.
In addition the default size for the Diffie-Hellman parameters on the server are increased to 2048 bits. This can be changed with ssl_set_dh_params() in case this is necessary.

an oversight in the portable version of fgetln() that allows attackers to read and write out-of-bounds memory
multiple denial-of-service vulnerabilities that allow local users to kill or hang OpenSMTPD
a stack-based buffer overflow that allows local users to crash OpenSMTPD, or execute arbitrary code as the non-chrooted _smtpd user
a hardlink attack (or race-conditioned symlink attack) that allows local users to unset the chflags() of arbitrary files
a hardlink attack that allows local users to read the first line of arbitrary files (for example, root's hash from /etc/master.passwd)
a denial-of-service vulnerability that allows remote attackers to fill OpenSMTPD's queue or mailbox hard-disk partition
an out-of-bounds memory read that allows remote attackers to crash OpenSMTPD, or leak information and defeat the ASLR protection
a use-after-free vulnerability that allows remote attackers to crash OpenSMTPD, or execute arbitrary code as the non-chrooted _smtpd user
The Apache James Project reports:
This release has many enhancements and bug fixes over the previous release. See the Release Notes for a detailed list of changes. Some of the earlier defects could turn a James mail server into an Open Relay and allow files to be written on disk. All users of James Server are urged to upgrade to version v2.3.2.1 as soon as possible.
The OTRS project reports:
An attacker with valid LOCAL credentials could access and manipulate the process ID file for bin/otrs.schduler.pl from the CLI.
The Proc::Daemon module 0.14 for Perl uses world-writable permissions for a file that stores a process ID, which allows local users to have an unspecified impact by modifying this file.

Security: The Session Library now uses HMAC authentication instead of a simple MD5 checksum.
The CodeIgniter changelog reports:
An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.
An incompatibility in PHP versions < 5.2.3 and MySQL > 5.0.7 with mysql_set_charset() creates a situation where using multi-byte character sets on these environments may potentially expose a SQL injection attack vector. Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.
If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.

Amos Jeffries, release manager of the Squid-3 series, reports:
Vulnerable versions are 3.5.0.1 to 3.5.8 (inclusive), which are built with OpenSSL and configured for "SSL-Bump" decryption.
Integer overflows can lead to invalid pointer math reading from random memory on some CPU architectures. In the best case this leads to wrong TLS extensions being used for the client, worst-case a crash of the proxy terminating all active transactions.
Incorrect message size checks and assumptions about the existence of TLS extensions in the SSL/TLS handshake message can lead to very high CPU consumption (up to and including 'infinite loop' behaviour).
The above can be triggered remotely. Though there is one layer of authorization applied before this processing to check that the client is allowed to use the proxy, that check is generally weak. MS Skype on Windows XP is known to trigger some of these.
The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

Bugzilla Security Advisory
Login names (usually an email address) longer than 127 characters are silently truncated in MySQL which could cause the domain name of the email address to be corrupted. An attacker could use this vulnerability to create an account with an email address different from the one originally requested. The login name could then be automatically added to groups based on the group's regular expression setting.

The Mozilla Project reports:
Security researcher regenrecht reported via TippingPoint's Zero Day Initiative the possibility of memory corruption during the decoding of Ogg Vorbis files. This can cause a crash during decoding and has the potential for remote code execution.
The RedHat Project reports:
Will Drewry of the Google Security Team reported multiple issues in OGG Vorbis and Tremor libraries, that could cause application using those libraries to crash (NULL pointer dereference or divide by zero), enter an infinite loop or cause heap overflow caused by integer overflow.
Guanxing Wen reports:
PCRE library is prone to a vulnerability which leads to Heap Overflow. During the compilation of a malformed regular expression, more data is written on the malloced block than the expected size output by compile_regex(). The Heap Overflow vulnerability is caused by the following regular expression.
/(?J:(?|(:(?|(?'R')(\z(?|(?'R')(\k'R')|((?'R')))k'R')|((?'R')))H'Ak'Rf)|s(?'R')))/
A dry run of this particular regular expression with pcretest will reports "double free or corruption (!prev)". But it is actually a heap overflow problem. The overflow only affects pcre 8.x branch, pcre2 branch is not affected.
Drupal development team reports:
This security advisory fixes multiple vulnerabilities. See below for a list.
Cross-site Scripting - Ajax system - Drupal 7
A vulnerability was found that allows a malicious user to perform a cross-site scripting attack by invoking Drupal.ajax() on a whitelisted HTML element.
This vulnerability is mitigated on sites that do not allow untrusted users to enter HTML.
Cross-site Scripting - Autocomplete system - Drupal 6 and 7
A cross-site scripting vulnerability was found in the autocomplete functionality of forms. The requested URL is not sufficiently sanitized.
This vulnerability is mitigated by the fact that the malicious user must be allowed to upload files.
SQL Injection - Database API - Drupal 7
A vulnerability was found in the SQL comment filtering system which could allow a user with elevated permissions to inject malicious code in SQL comments.
This vulnerability is mitigated by the fact that only one contributed module that the security team found uses the comment filtering system in a way that would trigger the vulnerability. That module requires you to have a very high level of access in order to perform the attack.
Cross-site Request Forgery - Form API - Drupal 6 and 7
A vulnerability was discovered in Drupal's form API that could allow file upload value callbacks to run with untrusted input, due to form token validation not being performed early enough. This vulnerability could allow a malicious user to upload files to the site under another user's account.
This vulnerability is mitigated by the fact that the uploaded files would be temporary, and Drupal normally deletes temporary files automatically after 6 hours.
Information Disclosure in Menu Links - Access system - Drupal 6 and 7
Users without the "access content" permission can see the titles of nodes that they do not have access to, if the nodes are added to a menu on the site that the users have access to.
OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world-writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev.
Fixed a privilege separation weakness related to PAM support. Attackers who could successfully compromise the pre-authentication process for remote code execution and who had valid credentials on the host could impersonate other users.
Fixed a use-after-free bug related to PAM support that was reachable by attackers who could compromise the pre-authentication process for remote code execution.
OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas.
Colin Percival reports:
1. SECURITY FIX: When constructing paths of objects being archived, a buffer could overflow by one byte upon encountering 1024, 2048, 4096, etc. byte paths. Theoretically this could be exploited by an unprivileged user whose files are being archived; I do not believe it is exploitable in practice, but I am offering a $1000 bounty for the first person who can prove me wrong: http://www.daemonology.net/blog/2015-08-21-tarsnap-1000-exploit-bounty.html
2. SECURITY FIX: An attacker with a machine's write keys, or with read keys and control of the tarsnap service, could make tarsnap allocate a large amount of memory upon listing archives or reading an archive the attacker created; on 32-bit machines, tarsnap can be caused to crash under the aforementioned conditions.
oCERT reports:
The stable VLC version suffers from an arbitrary pointer dereference vulnerability.
The vulnerability affects the 3GP file format parser, insufficient restrictions on a writable buffer can be exploited to execute arbitrary code via the heap memory. A specific 3GP file can be crafted to trigger the vulnerability.
Credit: vulnerability reported by Loren Maggiore of Trail of Bits.
Pengsu Cheng reports:
An use-after-free issue in Decoder.cpp was reported to upstream. The problem is due to lack of validation of ColorTableSize.
Gustavo Grieco reports:
We found a heap overflow and a DoS in the gdk-pixbuf implementation triggered by the scaling of a malformed bmp.
Tim Graham reports:
Denial-of-service possibility in logout() view by filling session store
Previously, a session could be created when anonymously accessing the django.contrib.auth.views.logout view (provided it wasn't decorated with django.contrib.auth.decorators.login_required as done in the admin). This could allow an attacker to easily create many new session records by sending repeated requests, potentially filling up the session store or causing other users' session records to be evicted.
The django.contrib.sessions.middleware.SessionMiddleware has been modified to no longer create empty session records.
This portion of the fix has been assigned CVE-2015-5963.
Additionally, on the 1.4 and 1.7 series only, the contrib.sessions.backends.base.SessionBase.flush() and cache_db.SessionStore.flush() methods have been modified to avoid creating a new empty session. Maintainers of third-party session backends should check if the same vulnerability is present in their backend and correct it if so.
This portion of the fix has been assigned CVE-2015-5964. Anyone reporting a similar vulnerability in a third-party session backend should not use this CVE ID.
Thanks Lin Hua Cheng for reporting the issue.
Unreal reports:
Summary: If SASL support is enabled in UnrealIRCd (this is not the default) and is also enabled in your services package then a malicious user with a services account can cause UnrealIRCd to crash.
Martin Prpic reports:
A double free flaw was found in the way JasPer's jasper_image_stop_load() function parsed certain JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.
Feist Josselin reports:
A new use-after-free was found in Jasper JPEG-200. The use-after-free appears in the function mif_process_cmpt of the src/libjasper/mif/mif_cod.c file.
Stefan Cornelius reports:
There's an integer overflow in the allocate_cells() function when trying to allocate the memory for worksheet with specially crafted row/column dimensions. This can be exploited to cause a heap memory corruption. The most likely outcome of this is a crash when trying to initialize the cells later in the function.
Jodie Cunningham reports:
#1: A flaw was found in the way FreeXL reads sectors from the input file. A specially crafted file could possibly result in stack corruption near freexl.c:3752.
#2: A flaw was found in the function allocate_cells(). A specially crafted file with invalid workbook dimensions could possibly result in stack corruption near freexl.c:1074
#3: A flaw was found in the way FreeXL handles a premature EOF. A specially crafted input file could possibly result in stack corruption near freexl.c:1131
#4: FreeXL 1.0.0g did not properly check requests for workbook memory allocation. A specially crafted input file could cause a Denial of Service, or possibly write onto the stack.
NIST reports:
Apache Tomcat Connectors (mod_jk) before 1.2.41 ignores JkUnmount rules for subtrees of previous JkMount rules, which allows remote attackers to access otherwise restricted artifacts via unspecified vectors.
The Xen Project reports:
The QEMU model of the RTL8139 network card did not sufficiently validate inputs in the C+ mode offload emulation. This results in uninitialized memory from the QEMU process's heap being leaked to the domain as well as to the network.
A guest may be able to read sensitive host-level data relating to itself which resides in the QEMU process.
Such information may include things such as information relating to real devices backing emulated devices or passwords which the host administrator does not intend to share with the guest admin.
The Xen Project reports:
When unplugging an emulated block device the device was not fully unplugged, meaning a second unplug attempt would attempt to unplug the device a second time using a previously freed pointer.
An HVM guest which has access to an emulated IDE disk device may be able to exploit this vulnerability in order to take over the qemu process elevating its privilege to that of the qemu process.
The PHP project reports:

MediaWiki reports:
Internal review discovered that Special:DeletedContributions did not properly protect the IP of autoblocked users. This fix makes the functionality of Special:DeletedContributions consistent with Special:Contributions and Special:BlockList.
Internal review discovered that watchlist anti-csrf tokens were not being compared in constant time, which could allow various timing attacks. This could allow an attacker to modify a user's watchlist via csrf
John Menerick reported that MediaWiki's thumb.php failed to sanitize various error messages, resulting in xss.
Jouni Malinen reports:
The EAP-PWD module performed insufficient validation on packets received from an EAP peer. This module is not enabled in the default configuration. Administrators must manually enable it for their server to be vulnerable. Only versions 3.0 up to 3.0.8 are affected.
gnutls.org reports:
Kurt Roeckx reported that decoding a specific certificate with very long DistinguishedName (DN) entries leads to double free, which may result to a denial of service. Since the DN decoding occurs in almost all applications using certificates it is recommended to upgrade the latest GnuTLS version fixing the issue. Recommendation: Upgrade to GnuTLS 3.4.4, or 3.3.17.
Karthikeyan Bhargavan reports:
GnuTLS does not by default support MD5 signatures. Indeed the RSA-MD5 signature-hash algorithm needs to be explicitly enabled using the priority option VERIFY_ALLOW_SIGN_RSA_MD5. In the NORMAL and SECURE profiles, GnuTLS clients do not offer RSA-MD5 in the signature algorithms extension. However, we find that all GnuTLS clients still accept RSA-MD5 in the ServerKeyExchange and GnuTLS servers still accept RSA-MD5 in the ClientCertificateVerify.
oss-security-list@demlak.de reports:
An unauthenticated remote attacker is able to get the database password via webaccess due to wrong file permissions of the /logs/ folder in froxlor version 0.9.33.1 and earlier. The plain SQL password and username may be stored in the /logs/sql-error.log file. This directory is publicly reachable under the default configuration/setup.
Note that froxlor 0.9.33.2 prevents future logging of passwords but does not retroactively remove passwords already logged. Michael Kaufmann, the Froxlor lead developer reports:
Removing all .log files from the directory should do the job, alternatively just use the class.ConfigIO.php from Github
Best Practical reports:
RT 4.0.0 and above are vulnerable to a cross-site scripting (XSS) attack via the user and group rights management pages. This vulnerability is assigned CVE-2015-5475. It was discovered and reported by Marcin Kopec at Data Reliance Shared Service Center.
RT 4.2.0 and above are vulnerable to a cross-site scripting (XSS) attack via the cryptography interface. This vulnerability could allow an attacker with a carefully-crafted key to inject JavaScript into RT's user interface. Installations which use neither GnuPG nor S/MIME are unaffected.
Brian Warner reports:
The "flappserver" feature was found to have a vulnerability in the service-lookup code which, when combined with an attacker who has the ability to write files to a location where the flappserver process could read them, would allow that attacker to obtain control of the flappserver process.
The Mozilla Project reports:
Using the Address Sanitizer tool, security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team found an out-of-bounds write when buffering WebM format video containing frames with invalid tile sizes. This can lead to a potentially exploitable crash during WebM video playback.
Adobe reports:
Adobe has released security updates for Adobe Flash Player. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

Shibboleth consortium reports:
Shibboleth SP software crashes on well-formed but invalid XML.
The Service Provider software contains a code path with an uncaught exception that can be triggered by an unauthenticated attacker by supplying well-formed but schema-invalid XML in the form of SAML metadata or SAML protocol messages. The result is a crash and so causes a denial of service.
You must rebuild opensaml and shibboleth with xmltooling-1.5.5 or later. The easiest way to do so is to update the whole chain including shibboleth-2.5.5 an opensaml2.5.5.

oCERT reports:
The FreeRADIUS server relies on OpenSSL to perform certificate validation, including Certificate Revocation List (CRL) checks. The FreeRADIUS usage of OpenSSL, in CRL application, limits the checks to leaf certificates, therefore not detecting revocation of intermediate CA certificates.
An unexpired client certificate, issued by an intermediate CA with a revoked certificate, is therefore accepted by FreeRADIUS.
Specifically sets the X509_V_FLAG_CRL_CHECK flag for leaf certificate CRL checks, but does not use X509_V_FLAG_CRL_CHECK_ALL for CRL checks on the complete trust chain.
The FreeRADIUS project advises that the recommended configuration is to use self-signed CAs for all EAP-TLS methods.
The Xen Project reports:
The xl command line utility mishandles long configuration values when passed as command line arguments, with a buffer overrun.
A semi-trusted guest administrator or controller, who is intended to be able to partially control the configuration settings for a domain, can escalate their privileges to that of the whole host.
The Xen Project reports:
A buggy loop in Xen's compat_iret() function iterates the wrong way around a 32-bit index. Any 32-bit PV guest kernel can trigger this vulnerability by attempting a hypercall_iret with EFLAGS.VM set.
Given the use of __get/put_user(), and that the virtual addresses in question are contained within the lower canonical half, the guest cannot clobber any hypervisor data. Instead, Xen will take up to 2^33 pagefaults, in sequence, effectively hanging the host.
Malicious guest administrators can cause a denial of service affecting the whole system.
The Xen Project reports:
With the introduction of version 2 grant table operations, a version check became necessary for most grant table related hypercalls. The GNTTABOP_swap_grant_ref call was lacking such a check. As a result, the subsequent code behaved as if version 2 was in use, when a guest issued this hypercall without a prior GNTTABOP_setup_table or GNTTABOP_set_version.
The effect is a possible NULL pointer dereferences. However, this cannot be exploited to elevate privileges of the attacking domain, as the maximum memory address that can be wrongly accessed this way is bounded to far below the start of hypervisor memory.
Malicious or buggy guest domain kernels can mount a denial of service attack which, if successful, can affect the whole system.
The Xen Project reports:
The handler for XEN_DOMCTL_gettscinfo failed to initialize a padding field subsequently copied to guest memory.
A similar leak existed in XEN_SYSCTL_getdomaininfolist, which is being addressed here regardless of that operation being declared unsafe for disaggregation by XSA-77.
Malicious or buggy stub domain kernels or tool stacks otherwise living outside of Domain0 may be able to read sensitive data relating to the hypervisor or other guests not under the control of that domain.
The Xen Project reports:
Qemu allows guests to not only read, but also write all parts of the PCI config space (but not extended config space) of passed through PCI devices not explicitly dealt with for (partial) emulation purposes.
Since the effect depends on the specific purpose of the the config space field, it's not possible to give a general statement about the exact impact on the host or other guests. Privilege escalation, host crash (Denial of Service), and leaked information all cannot be excluded.
The Xen Project reports:
Device model code dealing with guest PCI MSI-X interrupt management activities logs messages on certain (supposedly) invalid guest operations.
A buggy or malicious guest repeatedly invoking such operations may result in the host disk to fill up, possibly leading to a Denial of Service.
The Xen Project reports:
The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits.
Interrupts may be observed by Xen at unexpected times, which may lead to a host crash and therefore a Denial of Service.
The Xen Project reports:
Logic is in place to avoid writes to certain host config space fields when the guest must nevertheless be able to access their virtual counterparts. A bug in how this logic deals with accesses spanning multiple fields allows the guest to write to the host MSI message data field.
While generally the writes write back the values previously read, their value in config space may have got changed by the host between the qemu read and write. In such a case host side interrupt handling could become confused, possibly losing interrupts or allowing spurious interrupt injection into other guests.
Certain untrusted guest administrators may be able to confuse host side interrupt handling, leading to a Denial of Service.
The Xen Project reports:
XSA-77 put the majority of the domctl operations on a list excepting them from having security advisories issued for them if any effects their use might have could hamper security. Subsequently some of them got declared disaggregation safe, but for a small subset this was not really correct: Their (mis-)use may result in host lockups.
As a result, the potential security benefits of toolstack disaggregation are not always fully realised.
Domains deliberately given partial management control may be able to deny service to the entire host.
As a result, in a system designed to enhance security by radically disaggregating the management, the security may be reduced. But, the security will be no worse than a non-disaggregated design.
The Xen Project reports:
HVM guests are currently permitted to modify the memory and I/O decode bits in the PCI command register of devices passed through to them. Unless the device is an SR-IOV virtual function, after disabling one or both of these bits subsequent accesses to the MMIO or I/O port ranges would - on PCI Express devices - lead to Unsupported Request responses. The treatment of such errors is platform specific.
Furthermore (at least) devices under control of the Linux pciback driver in the host are handed to guests with the aforementioned bits turned off. This means that such accesses can similarly lead to Unsupported Request responses until these flags are set as needed by the guest.
In the event that the platform surfaces aforementioned UR responses as Non-Maskable Interrupts, and either the OS is configured to treat NMIs as fatal or (e.g. via ACPI's APEI) the platform tells the OS to treat these errors as fatal, the host would crash, leading to a Denial of Service.
The Xen Project reports:
The XEN_DOMCTL_memory_mapping hypercall allows long running operations without implementing preemption.
This hypercall is used by the device model as part of the emulation associated with configuration of PCI devices passed through to HVM guests and is therefore indirectly exposed to those guests.
This can cause a physical CPU to become busy for a significant period, leading to a host denial of service in some cases.
If a host denial of service is not triggered then it may instead be possible to deny service to the domain running the device model, e.g. domain 0.
This hypercall is also exposed more generally to all toolstacks. However the uses of it in libxl based toolstacks are not believed to open up any avenue of attack from an untrusted guest. Other toolstacks may be vulnerable however.
The vulnerability is exposed via HVM guests which have a PCI device assigned to them. A malicious HVM guest in such a configuration can mount a denial of service attack affecting the whole system via its associated device model (qemu-dm).
A guest is able to trigger this hypercall via operations which it is legitimately expected to perform, therefore running the device model as a stub domain does not offer protection against the host denial of service issue. However it does offer some protection against secondary issues such as denial of service against dom0.
The Xen Project reports:
Instructions with register operands ignore eventual segment overrides encoded for them. Due to an insufficiently conditional assignment such a bogus segment override can, however, corrupt a pointer used subsequently to store the result of the instruction.
A malicious guest might be able to read sensitive data relating to other guests, or to cause denial of service on the host. Arbitrary code execution, and therefore privilege escalation, cannot be excluded.
The Xen Project reports:
The code handling certain sub-operations of the HYPERVISOR_xen_version hypercall fails to fully initialize all fields of structures subsequently copied back to guest memory. Due to this hypervisor stack contents are copied into the destination of the operation, thus becoming visible to the guest.
A malicious guest might be able to read sensitive data relating to other guests.
The Xen Project reports:
Emulation routines in the hypervisor dealing with certain system devices check whether the access size by the guest is a supported one. When the access size is unsupported these routines failed to set the data to be returned to the guest for read accesses, so that hypervisor stack contents are copied into the destination of the operation, thus becoming visible to the guest.
A malicious HVM guest might be able to read sensitive data relating to other guests.
The Xen Project reports:
When instantiating an emulated VGA device for an x86 HVM guest qemu will by default enable a backend to expose that device, either SDL or VNC depending on the version of qemu and the build time configuration.
The libxl toolstack library does not explicitly disable these default backends when they are not enabled, leading to an unexpected backend running.
If either SDL or VNC is explicitly enabled in the guest configuration then only the expected backends will be enabled.
This affects qemu-xen and qemu-xen-traditional differently.
If qemu-xen was compiled with SDL support then this would result in an SDL window being opened if $DISPLAY is valid, or a failure to start the guest if not.
If qemu-xen was compiled without SDL support then qemu would instead start a VNC server listening on ::1 (IPv6 localhost) or 127.0.0.1 (IPv4 localhost) with IPv6 preferred if available. A VNC password will not be configured even if one is present in the guest configuration.
qemu-xen-traditional will never start a vnc backend unless explicitly configured. However by default it will start an SDL backend if it was built with SDL support and $DISPLAY is valid.
The Xen Project reports:
On ARM systems the code which deals with virtualizing the GIC distributor would, under various circumstances, log messages on a guest accessible code path without appropriate rate limiting.
A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.
The Xen Project reports:
When decoding a guest write to a specific register in the virtual interrupt controller Xen would treat an invalid value as a critical error and crash the host.
By writing an invalid value to the GICD.SGIR register a guest can crash the host, resulting in a Denial of Service attack.

OpenSSL reports:
During certificate verification, OpenSSL (starting from version 1.0.1n and 1.0.2b) will attempt to find an alternative certificate chain if the first attempt to build such a chain fails. An error in the implementation of this logic can mean that an attacker could cause certain checks on untrusted certificates to be bypassed, such as the CA flag, enabling them to use a valid leaf certificate to act as a CA and "issue" an invalid certificate.

Adobe has released security updates for Adobe Flash Player. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system. Adobe is aware of a report that an exploit targeting CVE-2015-5119 has been publicly published.
ISC reports:
A very uncommon combination of zone data has been found that triggers a bug in BIND, with the result that named will exit with a "REQUIRE" failure in name.c when validating the data returned in answer to a recursive query.
A recursive resolver that is performing DNSSEC validation can be deliberately terminated by any attacker who can cause a query to be performed against a maliciously constructed zone. This will result in a denial of service to clients who rely on that resolver.
HAProxy reports:
A vulnerability was found when HTTP pipelining is used. In some cases, a client might be able to cause a buffer alignment issue and retrieve uninitialized memory contents that exhibit data from a past request or session. I want to address sincere congratulations to Charlie Smurthwaite of aTech Media for the really detailed traces he provided which made it possible to find the cause of this bug. Every user of 1.5-dev, 1.5.x or 1.6-dev must upgrade to 1.5.14 or latest 1.6-dev snapshot to fix this issue, or use the backport of the fix provided by their operating system vendors. CVE-2015-3281 was assigned to this bug.
Roundcube reports:
We just published updates to both stable versions 1.0 and 1.1 after fixing many minor bugs and adding some security improvements to the 1.1 release branch. Version 1.0.6 comes with cherry-picked fixes from the more recent version to ensure proper long term support especially in regards of security and compatibility.
The security-related fixes in particular are:
* XSS vulnerability in _mbox argument
* security improvement in contact photo handling
* potential info disclosure from temp directory
Oleg Moskalenko reports:
SQL injection security hole fixed.
Squid security advisory 2015:2 reports:
Squid configured with cache_peer and operating on explicit proxy traffic does not correctly handle CONNECT method peer responses.
The bug is important because it allows remote clients to bypass security in an explicit gateway proxy.
However, the bug is exploitable only if you have configured cache_peer to receive CONNECT requests.
Squid security advisory 2015:1 reports:
Squid configured with client-first SSL-bump does not correctly validate X509 server certificate domain / hostname fields.
The bug is important because it allows remote servers to bypass client certificate validation. Some attackers may also be able to use valid certificates for one domain signed by a global Certificate Authority to abuse an unrelated domain.
However, the bug is exploitable only if you have configured Squid to perform SSL Bumping with the "client-first" or "bump" mode of operation.
Sites that do not use SSL-Bump are not vulnerable.
All Squid built without SSL support are not vulnerable to the problem.
The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

MITRE reports:
runner/connection_plugins/ssh.py in Ansible before 1.2.3, when using ControlPersist, allows local users to redirect a ssh session via a symlink attack on a socket file with a predictable name in /tmp/.
lib/ansible/playbook/__init__.py in Ansible 1.2.x before 1.2.3, when playbook does not run due to an error, allows local users to overwrite arbitrary files via a symlink attack on a retry file with a predictable name in /var/tmp/ansible/.
Ansible changelog reports:
Host key checking is on by default. Disable it if you like by adding host_key_checking=False in the [default] section of /etc/ansible/ansible.cfg or ~/ansible.cfg or by exporting ANSIBLE_HOST_KEY_CHECKING=False.
Gregory Maxwell reports:
On July 7th I will be making public details of several serious denial of service vulnerabilities which have fixed in recent versions of Bitcoin Core, including including CVE-2015-3641. I strongly recommend anyone running production nodes exposed to inbound connections from the internet upgrade to 0.10.2 as soon as possible.
node reports:
This release of Node.js fixes a bug that triggers an out-of-band write in V8's utf-8 decoder. This bug impacts all Buffer to String conversions. This is an important security update as this bug can be used to cause a denial of service attack.
Stefan Cornelius from Red Hat reports:
An integer overflow flaw leading to a heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker being able to submit print jobs could exploit this flaw to crash texttopdf or, possibly, execute arbitrary code with the privileges of the 'lp' user.
Tim Waugh reports:
The Page allocation is moved into textcommon.c, where it does all the necessary checking: lower-bounds for CVE-2015-3258 and upper-bounds for CVE-2015-3259 due to integer overflows for the calloc() call initializing Page[0] and the memset() call in texttopdf.c's WritePage() function zeroing the entire array.
Daniel Veilland reports:
Enforce the reader to run in constant memory. One of the operation on the reader could resolve entities leading to the classic expansion issue. Make sure the buffer used for xmlreader operation is bounded. Introduce a new allocation type for the buffers for this effect.
Ignacio R. Morelle reports:
As mentioned in the Wesnoth 1.12.4 and Wesnoth 1.13.1 release announcements, a security vulnerability targeting add-on authors was found (bug #23504) which allowed a malicious user to obtain add-on server passphrases from the client's .pbl files and transmit them over the network, or store them in saved game files intended to be shared by the victim. This vulnerability affects all existing releases up to and including versions 1.12.2 and 1.13.0. Additionally, version 1.12.3 included only a partial fix that failed to guard users against attempts to read from .pbl files with an uppercase or mixed-case extension. CVE-2015-5069 and CVE-2015-5070 have been assigned to the vulnerability affecting .pbl files with a lowercase extension, and .pbl files with an uppercase or mixed-case extension, respectively.
Stefan Cornelius from Red Hat reports:
A heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filters processed print jobs with a specially crafted line size. An attacker being able to submit print jobs could exploit this flaw to crash texttopdf or, possibly, execute arbitrary code.
Till Kamppeter reports:
texttopdf: Fixed buffer overflow on size allocation of texttopdf when working with extremely small line sizes, which causes the size calculation to result in 0 (CVE-2015-3258, thanks to Stefan Cornelius from Red Hat for the patch).
ntp.org reports:
Under limited and specific circumstances an attacker can send a crafted packet to cause a vulnerable ntpd instance to crash. This requires each of the following to be true:
- ntpd set up to allow for remote configuration (not allowed by default), and
- knowledge of the configuration password, and
- access to a computer entrusted to perform remote configuration.
The QEMU security team reports:
A guest which has access to an emulated PCNET network device (e.g. with "model=pcnet" in their VIF configuration) can exploit this vulnerability to take over the qemu process elevating its privilege to that of the qemu process.
Elastic reports:
Vulnerability Summary: All Elasticsearch versions from 1.0.0 to 1.5.2 are vulnerable to an attack that uses Elasticsearch to modify files read and executed by certain other applications.
Remediation Summary: Users should upgrade to 1.6.0. Alternately, ensure that other applications are not present on the system, or that Elasticsearch cannot write into areas where these applications would read.
Elastic reports:
Vulnerability Summary: All Elasticsearch versions prior to 1.5.2 and 1.4.5 are vulnerable to a directory traversal attack that allows an attacker to retrieve files from the server running Elasticsearch when one or more site plugins are installed, or when Windows is the server OS.
Remediation Summary: Users should upgrade to 1.4.5 or 1.5.2. Users that do not want to upgrade can address the vulnerability by disabling site plugins. See the CVE description for additional options.
Elastic reports:
Vulnerability Summary: Elasticsearch versions 1.3.0-1.3.7 and 1.4.0-1.4.2 have vulnerabilities in the Groovy scripting engine that were introduced in 1.3.0. The vulnerability allows an attacker to construct Groovy scripts that escape the sandbox and execute shell commands as the user running the Elasticsearch Java VM.
Remediation Summary: Users should upgrade to 1.3.8 or 1.4.3. Users that do not want to upgrade can address the vulnerability by setting script.groovy.sandbox.enabled to false in elasticsearch.yml and restarting the node.
Elastic reports:
Vulnerability Summary: Elasticsearch versions 1.3.x and prior have a default configuration for CORS that allows an attacker to craft links that could cause a user's browser to send requests to Elasticsearch instances on their local network. These requests could cause data loss or compromise.
Remediation Summary: Users should either set "http.cors.enabled" to false, or set "http.cors.allow-origin" to the value of the server that should be allowed access, such as localhost or a server hosting Kibana. Disabling CORS entirely with the former setting is more secure, but may not be suitable for all use cases.
Elastic reports:
Vulnerability Summary: In Elasticsearch versions 1.1.x and prior, dynamic scripting is enabled by default. This could allow an attacker to execute OS commands.
Remediation Summary: Disable dynamic scripting.
Logstash 1.4.2 was bundled with Elasticsearch 1.1.1, which is vulnerable to CVE-2014-3120. These binaries are used in Elasticsearch output specifically when using the node protocol. Since a node client joins the Elasticsearch cluster, the attackers could use scripts to execute commands on the host OS using the node client's URL endpoint. With 1.4.3 release, we are packaging Logstash with Elasticsearch 1.5.2 binaries which by default disables the ability to run scripts. This also affects users who are using the configuration option embedded=>true in the Elasticsearch output which starts a local embedded Elasticsearch cluster. This is typically used in development environment and proof of concept deployments. Regardless of this vulnerability, we strongly recommend not using embedded in production.
Note that users of transport and http protocol are not vulnerable to this attack.
Elastic reports:
An attacker could use the File output plugin with dynamic field references in the path option to traverse paths outside of Logstash directory. This technique could also be used to overwrite any files which can be accessed with permissions associated with Logstash user. This release sandboxes the paths which can be traversed using the configuration. We have also disallowed use of dynamic field references if the path options is pointing to an absolute path.
We have added this vulnerability to our CVE page and are working on filling out the CVE. We would like to thank Colin Coghill for reporting the issue and working with us on the resolution.
Elastic reports:
The vulnerability impacts deployments that use the either the zabbix or the nagios_nsca outputs. In these cases, an attacker with an ability to send crafted events to any source of data for Logstash could execute operating system commands with the permissions of the Logstash process.
Deployments that do not use the zabbix or the nagios_nsca outputs are not vulnerable and do not need to upgrade for this reason.
We have added this vulnerability to our CVE page and are working on filling out the CVE.
We would like to thank Jan Karwowski and Danila Borisiuk for reporting the issue and working with us on the resolution.
Elastic reports:
The combination of Logstash Forwarder and Lumberjack input (and output) was vulnerable to the POODLE attack in SSLv3 protocol. We have disabled SSLv3 for this combination and set the minimum version to be TLSv1.0. We have added this vulnerability to our CVE page and are working on filling out the CVE.
Thanks to Tray Torrance, Marc Chadwick, and David Arena for reporting this.
SSLv3 is no longer supported; TLS 1.0+ is required (compatible with Logstash 1.4.2+).
Adobe reports:
Adobe has released security updates for Adobe Flash Player for Windows, Macintosh and Linux. These updates address a critical vulnerability (CVE-2015-3113) that could potentially allow an attacker to take control of the affected system.
Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks. Systems running Internet Explorer for Windows 7 and below, as well as Firefox on Windows XP, are known targets.
Phill MV reports:
By submitting a specially crafted string to a service relying on the bson rubygem, an attacker may trigger denials of service or even inject data into victim's MongoDB instances.
The PHP project reports:

Postgres:
- Fixed bug #69667 (segfault in php_pgsql_meta_data). (CVE-2015-4644)
Kyle Kelley reports:
Summary: JSON error responses from the IPython notebook REST API contained URL parameters and were incorrectly reported as text/html instead of application/json. The error messages included some of these URL params, resulting in a cross site scripting attack. This affects users on Mozilla Firefox but not Chromium/Google Chrome.
API paths with issues:
- /api/contents (3.0-3.1)
- /api/notebooks (2.0-2.4, 3.0-3.1)

Jon Yurek reports:
Thanks to MORI Shingo of DeNA Co., Ltd. for reporting this.
There is an issue where if an HTML file is uploaded with a .html extension, but the content type is listed as being `image/jpeg`, this will bypass a validation checking for images. But it will also pass the spoof check, because a file named .html and containing actual HTML passes the spoof check.
This change makes it so that we also check the supplied content type. So even if the file contains HTML and ends with .html, it doesn't match the content type of `image/jpeg` and so it fails.
chicken developer Peter Bex reports:
Using gcc's Address Sanitizer, it was discovered that the string-translate* procedure from the data-structures unit can scan beyond the input string's length up to the length of the source strings in the map that's passed to string-translate*. This issue was fixed in master 8a46020, and it will make its way into CHICKEN 4.10.
This bug is present in all released versions of CHICKEN.
chicken developer Moritz Heidkamp reports:
The substring-index[-ci] procedures of the data-structures unit are vulnerable to a buffer overrun attack when passed an integer greater than zero as the optional START argument.
As a work-around you can switch to SRFI 13's string-contains procedure which also returns the substring's index in case it is found.

Russell Jenkins reports:
It was possible to abuse session cookie values so that file-based session stores such as Dancer::Session::YAML or Dancer2::Session::YAML would attempt to read/write from any file on the filesystem with the same extension the file-based store uses, such as '*.yml' for the YAML stores.
Drupal development team reports:
Impersonation (OpenID module - Drupal 6 and 7 - Critical)
A vulnerability was found in the OpenID module that allows a malicious user to log in as other users on the site, including administrators, and hijack their accounts.
This vulnerability is mitigated by the fact that the victim must have an account with an associated OpenID identity from a particular set of OpenID providers (including, but not limited to, Verisign, LiveJournal, or StackExchange).
Open redirect (Field UI module - Drupal 7 - Less critical)
The Field UI module uses a "destinations" query string parameter in URLs to redirect users to new destinations after completing an action on a few administration pages. Under certain circumstances, malicious users can use this parameter to construct a URL that will trick users into being redirected to a 3rd party website, thereby exposing the users to potential social engineering attacks.
This vulnerability is mitigated by the fact that only sites with the Field UI module enabled are affected.
Drupal 6 core is not affected, but see the similar advisory for the Drupal 6 contributed CCK module: SA-CONTRIB-2015-126
Open redirect (Overlay module - Drupal 7 - Less critical)
The Overlay module displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module does not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability.
This vulnerability is mitigated by the fact that it can only be used against site users who have the "Access the administrative overlay" permission, and that the Overlay module must be enabled.
Information disclosure (Render cache system - Drupal 7 - Less critical)
On sites utilizing Drupal 7's render cache system to cache content on the site by user role, private content viewed by user 1 may be included in the cache and exposed to non-privileged users.
This vulnerability is mitigated by the fact that render caching is not used in Drupal 7 core itself (it requires custom code or the contributed Render Cache module to enable) and that it only affects sites that have user 1 browsing the live site. Exposure is also limited if an administrative role has been assigned to the user 1 account (which is done, for example, by the Standard install profile that ships with Drupal core).
cURL reports:
libcurl can wrongly send HTTP credentials when re-using connections.
libcurl allows applications to set credentials for the upcoming transfer with HTTP Basic authentication, like with CURLOPT_USERPWD for example. Name and password. Just like all other libcurl options the credentials are sticky and are kept associated with the "handle" until something is made to change the situation.
Further, libcurl offers a curl_easy_reset() function that resets a handle back to its pristine state in terms of all settable options. A reset is of course also supposed to clear the credentials. A reset is typically used to clear up the handle and prepare it for a new, possibly unrelated, transfer.
Within such a handle, libcurl can also store a set of previous connections in case a second transfer is requested to a host name for which an existing connection is already kept alive.
With this flaw present, using the handle even after a reset would make libcurl accidentally use those credentials in a subsequent request if done to the same host name and connection as was previously accessed.
An example case would be first requesting a password protected resource from one section of a web site, and then do a second request of a public resource from a completely different part of the site without authentication. This flaw would then inadvertently leak the credentials in the second request.
libcurl can get tricked by a malicious SMB server to send off data it did not intend to.
In libcurl's state machine function handling the SMB protocol (smb_request_state()), two length and offset values are extracted from data that has arrived over the network, and those values are subsequently used to figure out what data range to send back.
The values are used and trusted without boundary checks and are just assumed to be valid. This allows carefully handcrafted packages to trick libcurl into responding and sending off data that was not intended. Or just crash if the values cause libcurl to access invalid memory.

Coverity scan (Static Analysis of source code)
afl-fuzz (security-oriented fuzzer).
Denis Andzakovic from Security Assessment for reporting an exploitable Stack Buffer Overflow.
Denis Andzakovic reports:
A buffer overflow is triggered within the software when a malicious disk image is attempted to be recovered. This may be leveraged by an attacker to crash TestDisk and gain control of program execution. An attacker would have to coerce the victim to run TestDisk against their malicious image.
Apache Software Foundation reports:
Low: Denial of Service CVE-2014-0230
When a response for a request with a request body is returned to the user agent before the request body is fully read, by default Tomcat swallows the remaining request body so that the next request on the connection may be processed. There was no limit to the size of request body that Tomcat would swallow. This permitted a limited Denial of Service as Tomcat would never close the connection and a processing thread would remain allocated to the connection.
Moderate: Security Manager bypass CVE-2014-7810
Malicious web applications could use expression language to bypass the protections of a Security Manager as expressions were evaluated within a privileged code section.
OSSEC reports:
The CVE-2015-3222 vulnerability, which allows for root escalation via sys check has been fixed in OSSEC 2.8.2. This issue does not affect agents.

StrongSwan Project reports
A denial-of-service and potential remote code execution vulnerability triggered by crafted IKE messages was discovered in strongSwan. Versions 5.2.2 and 5.3.0 are affected.
strongSwan Project reports:
An information leak vulnerability was fixed that, in certain IKEv2 setups, allowed rogue servers with a valid certificate accepted by the client to trick it into disclosing user credentials (even plain passwords if the client accepts EAP-GTC). This was caused because constraints against the server's authentication were enforced too late. All versions since 4.3.0 are affected.
Ben Murphy reports:
It is possible to break out of the Lua sandbox in Redis and execute arbitrary code.
This shouldn’t pose a threat to users under the trusted Redis security model where only trusted users can connect to the database. However, in real deployments there could be databases that can be accessed by untrusted users. The main deployments that are vulnerable are developers machines, places where redis servers can be reached via SSRF attacks and cloud hosting.
Geoff McLane reports:
tidy is affected by a write out of bounds when processing malformed html files.
This issue could be abused on server side applications that use php-tidy extension with user input.
The issue was confirmed, analyzed, and fixed by the tidy5 maintainer.

Avidemux is built with a bundled set of FFmpeg libraries. The bundled FFmpeg version has been updated from 1.2.10 to 1.2.12 to fix these security issues and other bugs fixed upstream in FFmpeg.
The open sourced vulnerability database reports:
REST Client for Ruby contains a flaw that is due to the application logging password information in plaintext. This may allow a local attacker to gain access to password information.
Andy Brody reports:
When Ruby rest-client processes an HTTP redirection response, it blindly passes along the values from any Set-Cookie headers to the redirection target, regardless of domain, path, or expiration.
Cabextract ChangeLog reports:
It was possible for cabinet files to extract to absolute file locations, and it was possible on Cygwin to get around cabextract's absolute and relative path protections by using backslashes.
There is a denial of service vulnerability in libmspack. The libmspack code is built into cabextract, so it is also vulnerable.
MITRE reports:
Integer overflow in the qtmd_decompress function in libmspack 0.4 allows remote attackers to cause a denial of service (hang) via a crafted CAB file, which triggers an infinite loop.
The Django project reports:
A change to session.flush() in the cached_db session backend in Django 1.8 mistakenly sets the session key to an empty string rather than None. An empty string is treated as a valid session key and the session cookie is set accordingly. Any users with an empty string in their session cookie will use the same session store. session.flush() is called by django.contrib.auth.logout() and, more seriously, by django.contrib.auth.login() when a user switches accounts. If a user is logged in and logs in again to a different account (without logging out) the session is flushed to avoid reuse. After the session is flushed (and its session key becomes '') the account details are set on the session and the session is saved. Any users with an empty string in their session cookie will now be logged into that account.
Thanks to Sam Cooke for reporting the issue.

MIT reports:
In MIT krb5 1.12 and later, when the KDC is configured with PKINIT support, an unauthenticated remote attacker can bypass the requires_preauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line dictionary attack against the user's password.
cURL reports:
libcurl provides applications a way to set custom HTTP headers to be sent to the server by using CURLOPT_HTTPHEADER. A similar option is available for the curl command-line tool with the '--header' option.
When the connection passes through an HTTP proxy the same set of headers is sent to the proxy as well by default. While this is by design, it has not necessarily been clear nor understood by application programmers.

libcurl keeps a pool of its last few connections around after use to facilitate easy, convenient, and completely transparent connection re-use for applications.
When doing HTTP requests NTLM authenticated, the entire connection becomes authenticated and not just the specific HTTP request which is otherwise how HTTP works. This makes NTLM special and a subject for special treatment in the code. With NTLM, once the connection is authenticated, no further authentication is necessary until the connection gets closed.
When doing HTTP requests Negotiate authenticated, the entire connection may become authenticated and not just the specific HTTP request which is otherwise how HTTP works, as Negotiate can basically use NTLM under the hood. curl was not adhering to this fact but would assume that such requests would also be authenticated per request.
libcurl supports HTTP "cookies" as documented in RFC 6265. Together with each individual cookie there are several different properties, but for this vulnerability we focus on the associated "path" element. It tells information about for which path on a given host the cookies is valid.
The internal libcurl function called sanitize_cookie_path() that cleans up the path element as given to it from a remote site or when read from a file, did not properly validate the input. If given a path that consisted of a single double-quote, libcurl would index a newly allocated memory area with index -1 and assign a zero to it, thus destroying heap memory it wasn't supposed to.
There is a private function in libcurl called fix_hostname() that removes a trailing dot from the host name if there is one. The function is called after the host name has been extracted from the URL libcurl has been told to act on.
If a URL is given with a zero-length host name, like in "http://:80" or just ":80", fix_hostname() will index the host name pointer with a -1 offset (as it blindly assumes a non-zero length) and both read and assign that address.
Jake Luciani reports:
Under its default configuration, Cassandra binds an unauthenticated JMX/RMI interface to all network interfaces. As RMI is an API for the transport and remote execution of serialized Java, anyone with access to this interface can execute arbitrary code as the running user.
Mitigation:
1.2.x has reached EOL, so users of <= 1.2.x are recommended to upgrade to a supported version of Cassandra, or manually configure encryption and authentication of JMX, (see https://wiki.apache.org/cassandra/JmxSecurity).
2.0.x users should upgrade to 2.0.14
2.1.x users should upgrade to 2.1.4
Alternately, users of any version not wishing to upgrade can reconfigure JMX/RMI to enable encryption and authentication according to https://wiki.apache.org/cassandra/JmxSecurityor http://docs.oracle.com/javase/7/docs/technotes/guides/management/agent.html

Colton Myers reports:
In order to fix potential shell injection vulnerabilities in salt modules, a change has been made to the various cmd module functions. These functions now default to python_shell=False, which means that the commands will not be sent to an actual shell.
The largest side effect of this change is that "shellisms", such as pipes, will not work by default. The modules shipped with salt have been audited to fix any issues that might have arisen from this change. Additionally, the cmd state module has been unaffected, and use of cmd.run in jinja is also unaffected. cmd.run calls on the CLI will also allow shellisms.
However, custom execution modules which use shellisms in cmd calls will break, unless you pass python_shell=True to these calls.
As a temporary workaround, you can set cmd_safe: False in your minion and master configs. This will revert the default, but is also less secure, as it will allow shell injection vulnerabilities to be written in custom code. We recommend you only set this setting for as long as it takes to resolve these issues in your custom code, then remove the override.

Jonathan Claudius reports:
RubyGems provides the ability of a domain to direct clients to a separate host that is used to fetch gems and make API calls against. This mechanism is implemented via DNS, specifically a SRV record _rubygems._tcp under the original requested domain.
RubyGems did not validate the hostname returned in the SRV record before sending requests to it. This left clients open to a DNS hijack attack, whereby an attacker could return a SRV of their choosing and get the client to use it.
Jason Geffner, CrowdStrike Senior Security Researcher reports:
VENOM, CVE-2015-3456, is a security vulnerability in the virtual floppy drive code used by many computer virtualization platforms. This vulnerability may allow an attacker to escape from the confines of an affected virtual machine (VM) guest and potentially obtain code-execution access to the host. Absent mitigation, this VM escape could open access to the host system and all other VMs running on that host, potentially giving adversaries significant elevated access to the host's local network and adjacent systems.

The OISF development team is pleased to announce Suricata 2.0.8. This release fixes a number of issues in the 2.0 series.
The most important issue is a bug in the DER parser which is used to decode SSL/TLS certificates could crash Suricata. This issue was reported by Kostya Kortchinsky of the Google Security Team and was fixed by Pierre Chifflier of ANSSI.
Those processing large numbers of (untrusted) pcap files need to update as a malformed pcap could crash Suricata. Again, credits go to Kostya Kortchinsky.
Andreas Schneider reports:
libssh versions 0.5.1 and above have a logical error in the handling of a SSH_MSG_NEWKEYS and SSH_MSG_KEXDH_REPLY package. A detected error did not set the session into the error state correctly and further processed the packet which leads to a null pointer dereference. This is the packet after the initial key exchange and doesn’t require authentication.
This could be used for a Denial of Service (DoS) attack.
US-CERT/NIST reports:
The HWP filter in LibreOffice before 4.3.7 and 4.4.x before 4.4.2 and Apache OpenOffice before 4.1.2 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted HWP document, which triggers an out-of-bounds write.
Samuel Sidler reports:
The Genericons icon font package, which is used in a number of popular themes and plugins, contained an HTML file vulnerable to a cross-site scripting attack. All affected themes and plugins hosted on WordPress.org (including the Twenty Fifteen default theme) have been updated today by the WordPress security team to address this issue by removing this nonessential file. To help protect other Genericons usage, WordPress 4.2.2 proactively scans the wp-content directory for this HTML file and removes it. Reported by Robert Abela of Netsparker.
WordPress versions 4.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. WordPress 4.2.2 includes a comprehensive fix for this issue.
The release also includes hardening for a potential cross-site scripting vulnerability when using the visual editor. This issue was reported by Mahadev Subedi.

Jouni Malinen reports:
A vulnerability was found in how wpa_supplicant uses SSID information parsed from management frames that create or update P2P peer entries (e.g., Probe Response frame or number of P2P Public Action frames). SSID field has valid length range of 0-32 octets. However, it is transmitted in an element that has a 8-bit length field and potential maximum payload length of 255 octets. wpa_supplicant was not sufficiently verifying the payload length on one of the code paths using the SSID received from a peer device.
This can result in copying arbitrary data from an attacker to a fixed length buffer of 32 bytes (i.e., a possible overflow of up to 223 bytes). The SSID buffer is within struct p2p_device that is allocated from heap. The overflow can override couple of variables in the struct, including a pointer that gets freed. In addition about 150 bytes (the exact length depending on architecture) can be written beyond the end of the heap allocation.
This could result in corrupted state in heap, unexpected program behavior due to corrupted P2P peer device information, denial of service due to wpa_supplicant process crash, exposure of memory contents during GO Negotiation, and potentially arbitrary code execution.
Vulnerable versions/configurations
wpa_supplicant v1.0-v2.4 with CONFIG_P2P build option enabled (which is not compiled by default).
Attacker (or a system controlled by the attacker) needs to be within radio range of the vulnerable system to send a suitably constructed management frame that triggers a P2P peer device information to be created or updated.
The vulnerability is easiest to exploit while the device has started an active P2P operation (e.g., has ongoing P2P_FIND or P2P_LISTEN control interface command in progress). However, it may be possible, though significantly more difficult, to trigger this even without any active P2P operation in progress.

Richard J. Moore reports:
Due to two recent vulnerabilities identified in the built-in image format handling code, it was decided that this area required further testing to determine if further issues remained. Fuzzing using afl-fuzz located a number of issues in the handling of BMP, ICO and GIF files. The issues exposed included denial of service and buffer overflows leading to heap corruption. It is possible the latter could be used to perform remote code execution.
Ruby Developers report:
After reviewing RFC 6125 and RFC 5280, we found multiple violations of matching hostnames and particularly wildcard certificates.
Ruby’s OpenSSL extension will now provide a string-based matching algorithm which follows more strict behavior, as recommended by these RFCs. In particular, matching of more than one wildcard per subject/SAN is no-longer allowed. As well, comparison of these values are now case-insensitive.
Mark Sapiro reports:
A path traversal vulnerability has been discovered and fixed. This vulnerability is only exploitable by a local user on a Mailman server where the suggested Exim transport, the Postfix postfix_to_mailman.py transport or some other programmatic MTA delivery not using aliases is employed.
The Asterisk project reports:
When Asterisk registers to a SIP TLS device and and verifies the server, Asterisk will accept signed certificates that match a common name other than the one Asterisk is expecting if the signed certificate has a common name containing a null byte after the portion of the common name that Asterisk expected. For example, if Asterisk is trying to register to www.domain.com, Asterisk will accept certificates of the form www.domain.com\x00www.someotherdomain.com

Jenkins Security Advisory:
Description
SECURITY-171, SECURITY-177 (Reflective XSS vulnerability)
An attacker without any access to Jenkins can navigate the user to a carefully crafted URL and have the user execute unintended actions. This vulnerability can be used to attack Jenkins inside firewalls from outside so long as the location of Jenkins is known to the attacker.
SECURITY-180 (forced API token change)
The part of Jenkins that issues a new API token was not adequately protected against anonymous attackers. This allows an attacker to escalate privileges on Jenkins.

Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered an issue in the parsing of BDF font files by libXfont. Additional testing by Alan Coopersmith and William Robinet with the American Fuzzy Lop (afl) tool uncovered two more issues in the parsing of BDF font files.
As libXfont is used by the X server to read font files, and an unprivileged user with access to the X server can tell the X server to read a given font file from a path of their choosing, these vulnerabilities have the potential to allow unprivileged users to run code with the privileges of the X server (often root access).
Adobe reports:
Adobe has released security updates for Adobe Flash Player for Windows, Macintosh and Linux. These updates address vulnerabilities that could potentially allow an attacker to take control of the affected system.

The Sympa Project reports:
The newsletter posting area in the web interface in Sympa 6.0.x before 6.0.10 and 6.1.x before 6.1.24 allows remote attackers to read arbitrary files via unspecified vectors.
Best Practical reports:
RT 3.0.0 and above, if running on Perl 5.14.0 or higher, are vulnerable to a remote denial-of-service via the email gateway; any installation which accepts mail from untrusted sources is vulnerable, regardless of the permissions configuration inside RT. This denial-of-service may encompass both CPU and disk usage, depending on RT's logging configuration. This vulnerability is assigned CVE-2014-9472.
RT 3.8.8 and above are vulnerable to an information disclosure attack which may reveal RSS feeds URLs, and thus ticket data; this vulnerability is assigned CVE-2015-1165. RSS feed URLs can also be leveraged to perform session hijacking, allowing a user with the URL to log in as the user that created the feed; this vulnerability is assigned CVE-2015-1464.
The phpMyAdmin development team reports:
Risk of BREACH attack due to reflected parameter.
With a large number of crafted requests it was possible to infer the CSRF token by a BREACH attack.
Mitigation factor: this vulnerability can only be exploited in the presence of another vulnerability that allows the attacker to inject JavaScript into victim's browser.
The Mono project reports:
Mono’s implementation of the SSL/TLS stack failed to check the order of the handshake messages. Which would allow various attacks on the protocol to succeed. Details of this vulnerability are discussed in SKIP-TLS post.
Mono’s implementation of SSL/TLS also contained support for the weak EXPORT cyphers and was susceptible to the FREAK attack.
Simon Tatham reports:
When PuTTY has sensitive data in memory and has no further need for it, it should wipe the data out of its memory, in case malware later gains access to the PuTTY process or the memory is swapped out to disk or written into a crash dump file. An obvious example of this is the password typed during SSH login; other examples include obsolete session keys, public-key passphrases, and the private halves of public keys.
PuTTY 0.63 and earlier versions, after loading a private key from a disk file, mistakenly leak a memory buffer containing a copy of the private key, in the function ssh2_load_userkey. The companion function ssh2_save_userkey (only called by PuTTYgen) can also leak a copy, but only in the case where the file it tried to save to could not be created.

Peter Hutterer reports:
Olivier Fourdan from Red Hat has discovered a protocol handling issue in the way the X server code base handles the XkbSetGeometry request.
The issue stems from the server trusting the client to send valid string lengths in the request data. A malicious client with string lengths exceeding the request length can cause the server to copy adjacent memory data into the XKB structs. This data is then available to the client via the XkbGetGeometry request. The data length is at least up to 64k, it is possible to obtain more data by chaining strings, each string length is then determined by whatever happens to be in that 16-bit region of memory.
A similarly crafted request can likely cause the X server to crash.
Ryan Tandy reports:

This update fixes multiple security issues reported in PostgreSQL over the past few months. All of these issues require prior authentication, and some require additional conditions, and as such are not considered generally urgent. However, users should examine the list of security holes patched below in case they are particularly vulnerable.
- CVE-2015-0241 Buffer overruns in "to_char" functions.
- CVE-2015-0242 Buffer overrun in replacement printf family of functions.
- CVE-2015-0243 Memory errors in functions in the pgcrypto extension.
- CVE-2015-0244 An error in extended protocol message reading.
- CVE-2014-8161 Constraint violation errors can cause display of values in columns which the user would not normally have rights to see.
SO-AND-SO reports:
CVE-2014-5352: In the MIT krb5 libgssapi_krb5 library, after gss_process_context_token() is used to process a valid context deletion token, the caller is left with a security context handle containing a dangling pointer. Further uses of this handle will result in use-after-free and double-free memory access violations. libgssrpc server applications such as kadmind are vulnerable as they can be instructed to call gss_process_context_token().
CVE-2014-9421: If the MIT krb5 kadmind daemon receives invalid XDR data from an authenticated user, it may perform use-after-free and double-free memory access violations while cleaning up the partial deserialization results. Other libgssrpc server applications may also be vulnerable if they contain insufficiently defensive XDR functions.
CVE-2014-9422: The MIT krb5 kadmind daemon incorrectly accepts authentications to two-component server principals whose first component is a left substring of "kadmin" or whose realm is a left prefix of the default realm.
CVE-2014-9423: libgssrpc applications including kadmind output four or eight bytes of uninitialized memory to the network as part of an unused "handle" field in replies to clients.
Ubuntu Security Notice USN-2489-1 reports:
Michal Zalewski discovered that unzip incorrectly handled certain malformed zip archives. If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly execute arbitrary code.
Debian reports:
web/acknowledge.c uses a string twice in a format string, but only allocates memory for one copy.
The RabbitMQ project reports:
Some user-controllable content was not properly HTML-escaped before being presented to a user in the management web UI:
- When a user unqueued a message from the management UI, message details (header names, arguments, etc.) were displayed unescaped. An attacker could publish a specially crafted message to add content or execute arbitrary Javascript code on behalf of a user, if this user unqueued the message from the management UI.
- When viewing policies, their name was displayed unescaped. An attacker could create a policy with a specially crafted name to add content or execute arbitrary Javascript code on behalf of a user who is viewing policies.
- When listing connected AMQP network clients, client details such as its version were displayed unescaped. An attacker could use a client with a specially crafted version field to add content or execute arbitrary Javascript code on behalf of a user who is viewing connected clients.
In all cases, the attacker needs a valid user account on the targeted RabbitMQ cluster.
Furthermore, some admin-controllable content was not properly escaped:
- user names;
- the cluster name.
Likewise, an attacker could add content or execute arbitrary Javascript code on behalf of a user using the management web UI. However, the attacker must be an administrator on the RabbitMQ cluster, thus a trusted user.

The Asterisk project reports:
CVE-2014-8150 reported an HTTP request injection vulnerability in libcURL. Asterisk uses libcURL in its func_curl.so module (the CURL() dialplan function), as well as its res_config_curl.so (cURL realtime backend) modules.
Since Asterisk may be configured to allow for user-supplied URLs to be passed to libcURL, it is possible that an attacker could use Asterisk as an attack vector to inject unauthorized HTTP requests if the version of libcURL installed on the Asterisk server is affected by CVE-2014-8150.
The Asterisk project reports:
Asterisk may be configured to only allow specific audio or video codecs to be used when communicating with a particular endpoint. When an endpoint sends an SDP offer that only lists codecs not allowed by Asterisk, the offer is rejected. However, in this case, RTP ports that are allocated in the process are not reclaimed.
This issue only affects the PJSIP channel driver in Asterisk. Users of the chan_sip channel driver are not affected.
As the resources are allocated after authentication, this issue only affects communications with authenticated endpoints.
Robert Krátký reports:
GHOST is a 'buffer overflow' bug affecting the gethostbyname() and gethostbyname2() function calls in the glibc library. This vulnerability allows a remote attacker that is able to make an application call to either of these functions to execute arbitrary code with the permissions of the user running the application. The gethostbyname() function calls are used for DNS resolving, which is a very common event. To exploit this vulnerability, an attacker must trigger a buffer overflow by supplying an invalid hostname argument to an application that performs a DNS resolution.
Adobe reports:
Successful exploitation could cause a crash and potentially allow an attacker to take control of the affected system. We are aware of reports that this vulnerability is being actively exploited in the wild via drive-by-download attacks against systems running Internet Explorer and Firefox on Windows 8.1 and below.
Bugzilla Security Advisory
Command Injection
Some code in Bugzilla does not properly utilize 3 arguments form for open() and it is possible for an account with editcomponents permissions to inject commands into product names and other attributes.
Information Leak
Using the WebServices API, a user can possibly execute imported functions from other non-WebService modules. A whitelist has now been added that lists explicit methods that can be executed via the API.
The Django project reports:
Today the Django team is issuing multiple releases -- Django 1.4.18, Django 1.6.10, and Django 1.7.3 -- as part of our security process. These releases are now available on PyPI and our download page.
These releases address several security issues. We encourage all users of Django to upgrade as soon as possible.
NVD reports:
Stack-based buffer overflow in utp.cpp in libutp, as used in Transmission before 2.74 and possibly other products, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted "micro transport protocol packets."
OpenSSL Security Advisory:
A memory leak can occur in the dtls1_buffer_record function under certain conditions. In particular this could occur if an attacker sent repeated DTLS records with the same sequence number but for the next epoch. The memory leak could be exploited by an attacker in a Denial of Service attack through memory exhaustion.
Adobe reports:
These updates address vulnerabilities that could potentially allow an attacker to take control of the affected system.

PolarSSL team reports:
During the parsing of a ASN.1 sequence, a pointer in the linked list of asn1_sequence is not initialized by asn1_get_sequence_of(). In case an error occurs during parsing of the list, a situation is created where the uninitialized pointer is passed to polarssl_free().
This sequence can be triggered when a PolarSSL entity is parsing a certificate. So practically this means clients when receiving a certificate from the server or servers in case they are actively asking for a client certificate.
oCERT reports:
The UnZip tool is an open source extraction utility for archives compressed in the zip format.
The unzip command line tool is affected by heap-based buffer overflows within the CRC32 verification, the test_compr_eb() and the getZip64Data() functions. The input errors may result in arbitrary code execution.
A specially crafted zip file, passed to unzip -t, can be used to trigger the vulnerability.
Samba team reports:
In Samba's AD DC we neglected to ensure that attempted modifications of the userAccountControl attribute did not allow the UF_SERVER_TRUST_ACCOUNT bit to be set.
Valentin Rusu reports:
Until KDE Applications 14.12.0, kwalletd incorrectly handled CBC encryption blocks when encrypting secrets in kwl files. The secrets were still encrypted, but the result binary data corresponded to an ECB encrypted block instead of CBC.
The ECB encryption algorithm, even if it'll scramble user data, will produce same encrypted byte sequence for the same input text. As a result, attackers may eventually find-out the encrypted text.

Debian Security Team reports:
Andrew Bartlett of Catalyst reported a defect affecting certain applications using the Libevent evbuffer API. This defect leaves applications which pass insanely large inputs to evbuffers open to a possible heap overflow or infinite loop. In order to exploit this flaw, an attacker needs to be able to find a way to provoke the program into trying to make a buffer chunk larger than what will fit into a single size_t or off_t.
cURL reports:
When libcurl sends a request to a server via a HTTP proxy, it copies the entire URL into the request and sends if off. If the given URL contains line feeds and carriage returns those will be sent along to the proxy too, which allows the program to for example send a separate HTTP request injected embedded in the URL. Many programs allow some kind of external sources to set the URL or provide partial pieces for the URL to ask for, and if the URL as received from the user is not stripped good enough this flaw allows malicious users to do additional requests in a way that was not intended, or just to insert request headers into the request that the program didn't intend. We are not aware of any exploit of this flaw.

MITRE reports:
wp-login.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 might allow remote attackers to reset passwords by leveraging access to an e-mail account that received a password-reset message.
wp-includes/http.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to conduct server-side request forgery (SSRF) attacks by referring to a 127.0.0.0/8 resource.
WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 might allow remote attackers to obtain access to an account idle since 2008 by leveraging an improper PHP dynamic type comparison for an MD5 hash.
Cross-site scripting (XSS) vulnerability in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to inject arbitrary web script or HTML via a crafted Cascading Style Sheets (CSS) token sequence in a post.
Cross-site scripting (XSS) vulnerability in Press This in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors
wp-includes/class-phpass.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to cause a denial of service (CPU consumption) via a long password that is improperly handled during hashing, a similar issue to CVE-2014-9016.
Cross-site request forgery (CSRF) vulnerability in wp-login.php in WordPress 3.7.4, 3.8.4, 3.9.2, and 4.0 allows remote attackers to hijack the authentication of arbitrary users for requests that reset passwords.
32-bit builds of PNG library are vulnerable to an unsigned integer overflow that is triggered by a crafted wide interlaced images. Overflow results in a heap corruption that will crash the application and may lead to the controlled overwrite of a selected portions of process address space.
RedHat reports:
Thomas Jarosch of Intra2net AG reported a number of denial of service issues (resource consumption) in the ELF parser used by file(1). These issues were fixed in the 5.21 release of file(1), but by mistake are missing from the changelog.
NVD reports:
The write_one_header function in mutt 1.5.23 does not properly handle newline characters at the beginning of a header, which allows remote attackers to cause a denial of service (crash) via a header with an empty body, which triggers a heap-based buffer overflow in the mutt_substrdup function.
CERT reports:
The Network Time Protocol (NTP) provides networked systems with a way to synchronize time for various services and applications. ntpd version 4.2.7 and previous versions allow attackers to overflow several buffers in a way that may allow malicious code to be executed. ntp-keygen prior to version 4.2.7p230 also uses a non-cryptographic random number generator when generating symmetric keys.
The buffer overflow vulnerabilities in ntpd may allow a remote unauthenticated attacker to execute arbitrary malicious code with the privilege level of the ntpd process. The weak default key and non-cryptographic random number generator in ntp-keygen may allow an attacker to gain information regarding the integrity checking and authentication encryption schemes.
The Git Project reports:
When using a case-insensitive filesystem an attacker can craft a malicious Git tree that will cause Git to overwrite its own .git/config file when cloning or checking out a repository, leading to arbitrary command execution in the client machine. If you are a hosting service whose users may fetch from your service to Windows or Mac OS X machines, you are strongly encouraged to update to protect such users who use existing versions of Git.
The OTRS project reports:
An attacker with valid OTRS credentials could access and manipulate ticket data of other users via the GenericInterface, if a ticket webservice is configured and not additionally secured.
Subversion Project reports:
Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives a REPORT request for some invalid formatted special URIs.
Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives a request for some invalid formatted special URIs.
We consider this to be a medium risk vulnerability. Repositories which allow for anonymous reads will be vulnerable without authentication. Unfortunately, no special configuration is required and all mod_dav_svn servers are vulnerable.
NVIDIA Unix security team reports:
The GLX indirect rendering support supplied on NVIDIA products is subject to the recently disclosed X.Org vulnerabilities (CVE-2014-8093, CVE-2014-8098) as well as internally identified vulnerabilities (CVE-2014-8298).
Depending on how it is configured, the X server typically runs with raised privileges, and listens for GLX indirect rendering protocol requests from a local socket and potentially a TCP/IP port. The vulnerabilities could be exploited in a way that causes the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.
ISC reports:
We have today posted updated versions of 9.9.6 and 9.10.1 to address a significant security vulnerability in DNS resolution. The flaw was discovered by Florian Maury of ANSSI, and applies to any recursive resolver that does not support a limit on the number of recursions. [CERTFR-2014-AVI-512], [USCERT VU#264212]
A flaw in delegation handling could be exploited to put named into an infinite loop, in which each lookup of a name server triggered additional lookups of more name servers. This has been addressed by placing limits on the number of levels of recursion named will allow (default 7), and on the number of queries that it will send before terminating a recursive query (default 50). The recursion depth limit is configured via the max-recursion-depth option, and the query limit via the max-recursion-queries option. For more information, see the security advisory at https://kb.isc.org/article/AA-01216/. [CVE-2014-8500] [RT #37580]
In addition, we have also corrected a potential security vulnerability in the GeoIP feature in the 9.10.1 release only. For more information on this issue, see the security advisory at https://kb.isc.org/article/AA-01217. [CVE-2014-8680]
The Asterisk project reports:
When handling a WebSocket frame the res_http_websocket module dynamically changes the size of the memory used to allow the provided payload to fit. If a payload length of zero was received the code would incorrectly attempt to resize to zero. This operation would succeed and end up freeing the memory but be treated as a failure. When the session was subsequently torn down this memory would get freed yet again causing a crash.
Users of the WebSocket functionality also did not take into account that provided text frames are not guaranteed to be NULL terminated. This has been fixed in chan_sip and chan_pjsip in the applicable versions.
Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way the X server code base handles requests from X clients, and has worked with X.Org's security team to analyze, confirm, and fix these issues.
The vulnerabilities could be exploited to cause the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.
The GLX extension to the X Window System allows an X client to send X protocol to the X server, to request that the X server perform OpenGL rendering on behalf of the X client. This is known as "GLX indirect rendering", as opposed to "GLX direct rendering" where the X client submits OpenGL rendering commands directly to the GPU, bypassing the X server and avoiding the X server code for GLX protocol handling.
Most GLX indirect rendering implementations share some common ancestry, dating back to "Sample Implementation" code from Silicon Graphics, Inc (SGI), which SGI originally commercially licensed to other Unix workstation and graphics vendors, and later released as open source, so those vulnerabilities may affect other licensees of SGI's code base beyond those running code from the X.Org Foundation or the XFree86 Project.

The phpMyAdmin development team reports:
- With a crafted database, table or column name it is possible to trigger an XSS attack in the table browse page.
- With a crafted ENUM value it is possible to trigger XSS attacks in the table print view and zoom search pages.
- With a crafted value for font size it is possible to trigger an XSS attack in the home page.
These vulnerabilities can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required pages. Moreover, exploitation of the XSS vulnerability related to the font size requires forgery of the pma_fontsize cookie.
In the GIS editor feature, a parameter specifying the geometry type was not correcly validated, opening the door to a local file inclusion attack.

Albert Aastals Cid reports:
kwebkitpart and the bookmarks:// io slave were not sanitizing input correctly allowing to some javascript being executed on the context of the referenced hostname.
Whilst in most cases, the JavaScript will be executed in an untrusted context, with the bookmarks IO slave, it will be executed in the context of the referenced hostname. It should however be noted that KDE mitigates this risk by attempting to ensure that such URLs cannot be embedded directly into Internet hosted content.
Yii PHP Framework developers report:
We are releasing Yii 1.1.15 to fix a security issue found in 1.1.14. We urge all 1.1.14 users to upgrade their Yii to this latest release. Note that the issue only affects 1.1.14. All previous releases are not affected. Upgrading to this release from 1.1.14 is very safe and will not break your existing code.
The vulnerability is in the CDetailView widget. When a Yii application uses this widget and configures the "value" property of a CDetailView attribute using end user inputs, it may allow attackers to potentially execute arbitrary PHP scripts on the server. We are not showing how to exploit it here to allow users to upgrade before details about the exploit become publicly known. To our knowledge the details of this issue are only known to core team members.

David Edmundson reports:
KDE workspace configuration module for setting the date and time has a helper program which runs as root for performing actions. This is secured with polkit.
This helper takes the name of the ntp utility to run as an argument. This allows a hacker to run any arbitrary command as root under the guise of updating the time.
An application can gain root priveledges from an admin user with either misleading information or no interaction.
On some systems the user will be shown a prompt to change the time. However, if the system has policykit-desktop-privileges installed, the datetime helper will be invoked by an admin user without any prompts.
Simon McVittie reports:
The patch issued by the D-Bus maintainers for CVE-2014-3636 was based on incorrect reasoning, and does not fully prevent the attack described as "CVE-2014-3636 part A", which is repeated below. Preventing that attack requires raising the system dbus-daemon's RLIMIT_NOFILE (ulimit -n) to a higher value. CVE-2014-7824 has been allocated for this vulnerability.
MITRE reports:
Absolute path traversal vulnerability in GNU Wget before 1.16, when recursion is enabled, allows remote FTP servers to write to arbitrary files, and consequently execute arbitrary code, via a LIST response that references the same filename within two entries, one of which indicates that the filename is for a symlink.
Konversation developers report:
Konversation's Blowfish ECB encryption support assumes incoming blocks to be the expected 12 bytes. The lack of a sanity-check for the actual size can cause a denial of service and an information leak to the local user.
TWiki developers report:
The debugenableplugins request parameter allows arbitrary Perl code execution.
Using an HTTP GET request towards a TWiki server, add a specially crafted debugenableplugins request parameter to TWiki's view script (typically port 80/TCP). Prior authentication may or may not be necessary.
A remote attacker can execute arbitrary Perl code to view and modify any file the webserver user has access to.
Example: http://www.example.com/do/view/Main/WebHome?debugenableplugins=BackupRestorePlugin%3bprint("Content-Type:text/html\r\n\r\nVulnerable!")%3bexit
The TWiki site is vulnerable if you see a page with text "Vulnerable!".
Kohsuke Kawaguchi from Jenkins team reports:
Historically, Jenkins master and slaves behaved as if they altogether form a single distributed process. This means a slave can ask a master to do just about anything within the confinement of the operating system, such as accessing files on the master or trigger other jobs on Jenkins.
This has increasingly become problematic, as larger enterprise deployments have developed more sophisticated trust separation model, where the administators of a master might take slaves owned by other teams. In such an environment, slaves are less trusted than the master. Yet the "single distributed process" assumption was not communicated well to the users, resulting in vulnerabilities in some deployments.
SECURITY-144 (CVE-2014-3665) introduces a new subsystem to address this problem. This feature is off by default for compatibility reasons. See Wiki for more details, who should turn this on, and implications.
CVE-2014-3566 is rated high. It only affects installations that accept slaves from less trusted computers, but this will allow an owner of of such slave to mount a remote code execution attack on Jenkins.
Aris Adamantiadis reports:
When accepting a new connection, the server forks and the child process handles the request. The RAND_bytes() function of openssl doesn't reset its state after the fork, but simply adds the current process id (getpid) to the PRNG state, which is not guaranteed to be unique.
The pidgin development team reports:
.
The phpMyAdmin development team reports:
With a crafted database or table name it is possible to trigger an XSS in SQL debug output when enabled and in server monitor page when viewing and analysing executed queries.
This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required pages. Moreover, debugging SQL is a developer option which is disabled by default and expected to be disabled in production environments.
The Asterisk project reports:
The POODLE vulnerability is described under CVE-2014-3566. This advisory describes the Asterisk's project susceptibility to this vulnerability.
RedHat reports:
A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior.
Drupal Security Team reports:
Drupal 7 includes a database abstraction API to ensure that queries executed against the database are sanitized to prevent SQL injection attacks. A vulnerability in this API allows an attacker to send specially crafted requests resulting in arbitrary SQL execution. Depending on the content of the requests this can lead to privilege escalation, arbitrary PHP execution, or other attacks. This vulnerability can be exploited by anonymous users.
The OpenSSL Project reports:
A flaw in the DTLS SRTP extension parsing code allows an attacker, who sends a carefully crafted handshake message, to cause OpenSSL to fail to free up to 64k of memory causing a memory leak. This could be exploited in a Denial Of Service attack. This issue affects OpenSSL 1.0.1 server implementations for both SSL/TLS and DTLS regardless of whether SRTP is used or configured. Implementations of OpenSSL that have been compiled with OPENSSL_NO_SRTP defined are not affected. [CVE-2014-3513].
When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. By sending a large number of invalid session tickets an attacker could exploit this issue in a Denial Of Service attack. [CVE-2014-3567].
OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications to block the ability for a MITM attacker to force a protocol downgrade.
Some client applications (such as browsers) will reconnect using a downgraded protocol to work around interoperability bugs in older servers. This could be exploited by an active man-in-the-middle to downgrade connections to SSL 3.0 even if both sides of the connection support higher protocols. SSL 3.0 contains a number of weaknesses including POODLE [CVE-2014-3566].
When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. [CVE-2014-3568].

Bugzilla Security Advisory
Unauthorized Account Creation
An attacker creating a new Bugzilla account can override certain parameters when finalizing the account creation that can lead to the user being created with a different email address than originally requested. The overridden login name could be automatically added to groups based on the group's regular expression setting.
Cross-Site Scripting
During an audit of the Bugzilla code base, several places were found where cross-site scripting exploits could occur which could allow an attacker to access sensitive information.
Information Leak
If a new comment was marked private to the insider group, and a flag was set in the same transaction, the comment would be visible to flag recipients even if they were not in the insider group.
Social Engineering
Search results can be exported as a CSV file which can then be imported into external spreadsheet programs. Specially formatted field values can be interpreted as formulas which can be executed and used to attack a user's computer.
Best Practical reports:
RT 4.2.0 and above may be vulnerable to arbitrary execution of code by way of CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277, or CVE-2014-6271 -- collectively known as "Shellshock." This vulnerability requires a privileged user with access to an RT instance running with SMIME integration enabled; it applies to both mod_perl and fastcgi deployments. If you have already taken upgrades to bash to resolve "Shellshock," you are protected from this vulnerability in RT, and there is no need to apply this patch. This vulnerability has been assigned CVE-2014-7227.
Jenkins Security Advisory:
Please reference CVE/URL list for details
Note that this is different than the public "Shellshock" issue.
Specially crafted environment variables could lead to remote arbitrary code execution. This was fixed in bash 4.3.27, however the port was patched with a mitigation in 4.3.25_2.
The phpMyAdmin development team reports:
With a crafted ENUM value it is possible to trigger an XSS in table search and table structure pages. This vulnerability can be triggered only by someone who is logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required pages.
RedHat security team reports:
It was discovered that the fixed-sized redir_stack could be forced to overflow in the Bash parser, resulting in memory corruption, and possibly leading to arbitrary code execution when evaluating untrusted input that would not otherwise be run as code.
An off-by-one error was discovered in the way Bash was handling deeply nested flow control constructs. Depending on the layout of the .bss segment, this could allow arbitrary execution of code that would not otherwise be executed by Bash.

Note that this crash does not occur when using the res_fax_digium module. While this crash technically occurs due to a configuration issue, as attempting to receive a fax from a channel driver that only contains textual information will never succeed, the likelihood of having it occur is sufficiently high as to warrant this advisory.
The squid-cache project reports:
Due to incorrect buffer management Squid can be caused by an attacker to write outside its allocated SNMP buffer.
Simon McVittie reports:
Do not accept an extra fd in the padding of a cmsg message, which could lead to a 4-byte heap buffer overrun (CVE-2014-3635).
Reduce default for maximum Unix file descriptors passed per message from 1024 to 16, preventing a uid with the default maximum number of connections from exhausting the system bus' file descriptors under Linux's default rlimit (CVE-2014-3636).
Disconnect connections that still have a fd pending unmarshalling after a new configurable limit, pending_fd_timeout (defaulting to 150 seconds), removing the possibility of creating an abusive connection that cannot be disconnected by setting up a circular reference to a connection's file descriptor (CVE-2014-3637).
Reduce default for maximum pending replies per connection from 8192 to 128, mitigating an algorithmic complexity denial-of-service attack (CVE-2014-3638).
Reduce default for authentication timeout on the system bus from 30 seconds to 5 seconds, avoiding denial of service by using up all unauthenticated connection slots; and when all unauthenticated connection slots are used up, make new connection attempts block instead of disconnecting them (CVE-2014-3639).
The nginx project reports:
Security: it was possible to reuse SSL sessions in unrelated contexts if a shared SSL session cache or the same TLS session ticket key was used for multiple "server" blocks (CVE-2014-3616).
The phpMyAdmin development team reports:
XSRF/CSRF due to DOM based XSS in the micro history feature.
By deceiving a logged-in user to click on a crafted URL, it is possible to perform remote code execution and in some cases, create a root account due to a DOM based XSS vulnerability in the micro history feature.
OSSEC reports:
This correction will create the temp file for the hosts deny file in /var/ossec and will use mktemp where available to create NON-predictable temp file name. In cases where mktemp is not available we have written a BAD version of mktemp, but should be a little better then just process id.
Bryan Call reports:
Below is our announcement for the security issue reported to us from Yahoo! Japan. All versions of Apache Traffic Server are vulnerable. We urge users to upgrade to either 4.2.1.1 or 5.0.1 immediately.

The phpMyAdmin development team reports:
Multiple XSS vulnerabilities in browse table, ENUM editor, monitor, query charts and table relations pages.
With a crafted database, table or a primary/unique key column name it is possible to trigger an XSS when dropping a row from the table. With a crafted column name it is possible to trigger an XSS in the ENUM editor dialog. With a crafted variable name or a crafted value for unit field it is possible to trigger a self-XSS when adding a new chart in the monitor page. With a crafted value for x-axis label it is possible to trigger a self-XSS in the query chart page. With a crafted relation name it is possible to trigger an XSS in table relations page.
XSS in view operations page.
With a crafted view name it is possible to trigger an XSS when dropping the view in view operation page.
serf Development list reports:
Serf provides APIs to retrieve information about a certificate. These APIs return the information as NUL terminated strings (commonly called C strings). X.509 uses counted length strings which may include a NUL byte. This means that a library user will interpret any information as ending upon seeing this NUL byte and will only see a partial value for that field.
Attackers could exploit this vulnerability to create a certificate that a client will accept for a different hostname than the full certificate is actually for by embedding a NUL byte in the certificate.
This can lead to a man-in-the-middle attack. There are no known instances of this problem being exploited in the wild and in practice it should be difficult to actually exploit this vulnerability.
Subversion Project reports:
Using the Serf RA layer of Subversion for HTTPS uses the apr_fnmatch API to handle matching wildcards in certificate Common Names and Subject Alternate Names. However, apr_fnmatch is not designed for this purpose. Instead it is designed to behave like common shell globbing. In particular this means that '*' is not limited to a single label within a hostname (i.e. it will match '.'). But even further apr_fnmatch supports '?' and character classes (neither of which are part of the RFCs defining how certificate validation works).
Subversion stores cached credentials by an MD5 hash based on the URL and the authentication realm of the server the credentials are cached for. MD5 has been shown to be subject to chosen plaintext hash collisions. This means it may be possible to generate an authentication realm which results in the same MD5 hash for a different URL.

An attacker can force an error condition which causes openssl to crash whilst processing DTLS packets due to memory being freed twice. This can be exploited through a Denial of Service attack. [CVE-2014-3505]
An attacker can force openssl to consume large amounts of memory whilst processing DTLS handshake messages. This can be exploited through a Denial of Service attack. [CVE-2014-3506]
By sending carefully crafted DTLS packets an attacker could cause openssl to leak memory. This can be exploited through a Denial of Service attack. [CVE-2014-3507]
OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject to a denial of service attack. A malicious server can crash the client with a null pointer dereference (read) by specifying an anonymous (EC)DH ciphersuite and sending carefully crafted handshake messages. [CVE-2014-3510]
A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS 1.0 instead of higher protocol versions when the ClientHello message is badly fragmented. This allows a man-in-the-middle attacker to force a downgrade to TLS 1.0 even if both the server and the client support a higher protocol version, by modifying the client's TLS records. [CVE-2014-3511]
A malicious client or server can send invalid SRP parameters and overrun an internal buffer. Only applications which are explicitly set up for SRP use are affected. [CVE-2014-3512]
Albert Aastals Cid reports:
krfb embeds libvncserver which embeds liblzo2, it contains various flaws that result in integer overflow problems.
This potentially allows a malicious application to create a possible denial of service or code execution. Due to the need to exploit precise details of the target architecture and threading it is unlikely that remote code execution can be achieved in practice.
Samba developers report:
A malicious browser can send packets that may overwrite the heap of the target nmbd NetBIOS name services daemon. It may be possible to use this to generate a remote code execution vulnerability as the superuser (root).
Tomas Trnka reports:
Gpgme contains a buffer overflow in the gpgsm status handler that could possibly be exploited using a specially crafted certificate.
Martin Sandsmark reports:
The KAuth framework uses polkit-1 API which tries to authenticate using the requestors PID. This is prone to PID reuse race conditions.
This potentially allows a malicious application to pose as another for authentication purposes when executing privileged actions.
The Tor Project reports:
Tor before 0.2.4.23 and 0.2.5 before 0.2.5.6-alpha maintains a circuit after an inbound RELAY_EARLY cell is received by a client, which makes it easier for remote attackers to conduct traffic-confirmation attacks by using the pattern of RELAY and RELAY_EARLY cells as a means of communicating information about hidden service names.
The i2p project reports:
XSS and remote execution vulnerabilities reported by Exodus Intelligence.
Exodus Intelligence reports:
The vulnerability we have found is able to perform remote code execution with a specially crafted payload. This payload can be customized to unmask a user and show the public IP address in which the user connected from within 'a couple of seconds.'
Adobe does not properly restrict the SWF file format, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks against Bugzilla's JSONP endpoint, possibly obtaining sensitive bug information, via a crafted OBJECT element with SWF content satisfying the character-set requirements of a callback API.
Apache HTTP SERVER PROJECT reports:
mod_deflate: The DEFLATE input filter (inflates request bodies) now limits the length and compression ratio of inflated request bodies to avoid denial of service via highly compressed bodies. See directives DeflateInflateLimitRequestBody, DeflateInflateRatioLimit, and DeflateInflateRatioBurst.
mod_cgid: Fix a denial of service against CGI scripts that do not consume stdin that could lead to lingering HTTPD child processes filling up the scoreboard and eventually hanging the server.

Fix a race condition in scoreboard handling, which could lead to a heap buffer overflow.
core: HTTP trailers could be used to replace HTTP headers late during request processing, potentially undoing or otherwise confusing modules that examined or modified request headers earlier. Adds "MergeTrailers" directive to restore legacy behavior.
Tomcat Security Team reports:
Tomcat does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
An integer overflow, when operated behind a reverse proxy, allows remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header.
An integer overflow in parseChunkHeader allows remote attackers to cause a denial of service (resource consumption) via a malformed chunk size in chunked transfer coding of a request during the streaming of data.

Melissa Stone reports:
The MCollective aes_security public key plugin does not correctly validate certs against the CA. By exploiting this vulnerability within a race/initialization window, an attacker with local access could initiate an unauthorized MCollective client connection with a server, and thus control the mcollective plugins running on that server. This vulnerability requires a collective be configured to use the aes_security plugin. Puppet Enterprise and open source MCollective are not configured to use the plugin and are not vulnerable by default.

The POP3 kioslave used by KMail will accept invalid certificates without presenting a dialog to the user due a bug that leads to an inability to display the dialog combined with an error in the way the result is checked.
This flaw allows an active attacker to perform MITM attacks against the ioslave which could result in the leakage of sensitive data such as the authentication details and the contents of emails.
Thijs Kinkhorst reports:
Postfixadmin has an SQL injection vulnerability. This vulnerability is only exploitable by authenticated users able to create new aliases.
Simon McVittie reports:
Alban Crequy at Collabora Ltd. discovered a bug in dbus-daemon's support for file descriptor passing. A malicious process could force system services or user applications to be disconnected from the D-Bus system bus by sending them a message containing a file descriptor, then causing that file descriptor to exceed the kernel's maximum recursion depth (itself introduced to fix a DoS) before dbus-daemon forwards the message to the victim process. Most services and applications exit when disconnected from the system bus, leading to a denial of service.
Additionally, Alban discovered that bug fd.o#79694, a bug previously reported by Alejandro Martínez Suárez which was n believed to be security flaw, could be used for a similar denial of service, by causing dbus-daemon to attempt to forward invalid file descriptors to a victim process when file descriptors become associated with the wrong message.

Michael Niedermayer and Luca Barbato report in upstream ffmpeg:
avutil/lzo: Fix integer overflow
Markus Franz Xaver Johannes Oberhumer reports, in the package's NEWS file:
Fixed a potential integer overflow condition in the "safe" decompressor variants which could result in a possible buffer overrun when processing maliciously crafted compressed input data.
As this issue only affects 32-bit systems and also can only happen if you use uncommonly huge buffer sizes where you have to decompress more than 16 MiB (2^24 bytes) compressed bytes within a single function call, the practical implications are limited.
Werner Koch reports:
This release includes a *security fix* to stop a possible DoS using garbled compressed data packets which can be used to put gpg into an infinite loop.
The samba project reports:
A malformed packet can cause the nmbd server to loop the CPU and prevent any further NetBIOS name service.
Valid unicode path names stored on disk can cause smbd to crash if an authenticated client attempts to read them using a non-unicode request.

Erik Ekman of the iodine project reports:
The client could bypass the password check by continuing after getting error from the server and guessing the network parameters. The server would still accept the rest of the setup and also network traffic.
The Asterisk project reports:
Asterisk Manager User Unauthorized Shell Access. Manager users can execute arbitrary shell commands with the MixMonitor manager action. Asterisk does not require system class authorization for a manager user to use the MixMonitor action, so any manager user who is permitted to use manager commands can potentially execute shell commands as the user executing the Asterisk process.
Exhaustion of Allowed Concurrent HTTP Connections. Establishing a TCP or TLS connection to the configured HTTP or HTTPS port respectively in http.conf and then not sending or completing a HTTP request will tie up a HTTP session. By doing this repeatedly until the maximum number of open HTTP sessions is reached, legitimate requests are blocked.
Simon MvVittie reports:

Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has discovered several issues in the way the libXfont library handles the responses it receives from xfs servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues.
Most of these issues stem from libXfont trusting the font server to send valid protocol data, and not verifying that the values will not overflow or cause other damage. This code is commonly called from the X server when an X Font Server is active in the font path, so may be running in a setuid-root process depending on the X server in use. Exploits of this path could be used by a local, authenticated user to attempt to raise privileges; or by a remote attacker who can control the font server to attempt to execute code with the privileges of the X server.
CVE MITRE reports:
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state.
Stefan Cornelius reports:
It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substitution in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially-crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.
This issue was discovered by Daniel Berrange of Red Hat.
OpenBSD and David Ramos reports:
Applications that use SSL_MODE_RELEASE_BUFFERS, such as nginx/apache, are prone to a race condition which may allow a remote attacker to crash the current service.
Richard J. Moore reports:
QXmlSimpleReader in Qt versions prior to 5.2 supports expansion of internal entities in XML documents without placing restrictions to ensure the document does not cause excessive memory usage. If an application using this API processes untrusted data then the application may use unexpected amounts of memory if a malicious document is processed.
It is possible to construct XML documents using internal entities that consume large amounts of memory and other resources to process, this is known as the 'Billion Laughs' attack. Qt versions prior to 5.2 did not offer protection against this issue.
strongSwan developers report:
Remote attackers are able to bypass authentication by rekeying an IKE_SA during (1) initiation or (2) re-authentication, which triggers the IKE_SA state to be set to established.

The Django project reports:
These releases address an unexpected code-execution issue, a caching issue which can expose CSRF tokens and a MySQL typecasting issue. While these issues present limited risk and may not affect all Django users, we encourage all users to evaluate their own risk and upgrade as soon as possible.
Applications that use SSL_MODE_RELEASE_BUFFERS, such as nginx, are prone to a race condition which may allow a remote attacker to inject random data into other connections.
The login form had no CSRF protection, meaning that an attacker could force the victim to log in using the attacker's credentials. If the victim then reports a new security sensitive bug, the attacker would get immediate access to this bug.
Due to changes involved in the Bugzilla API, this fix is not backported to the 4.0 and 4.2 branches, meaning that Bugzilla 4.0.12 and older, and 4.2.8 and older, will remain vulnerable to this issue.
Dangerous control characters can be inserted into Bugzilla, notably into bug comments. If the text, which may look safe, is copied into a terminal such as xterm or gnome-terminal, then unexpected commands could be executed on the local machine.
Jan Lieskovsky reports:
OpenLDAP does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority
cURL reports:

The OpenAFS development team reports:
An attacker with the ability to connect to an OpenAFS fileserver can trigger a buffer overflow, crashing the server.
The buffer overflow can be triggered by sending an unauthenticated request for file server statistical information.
Clients are not affected.
OpenSSL Reports:
A missing bounds check in the handling of the TLS heartbeat extension can be used to reveal up to 64k of memory to a connected client or server.
Affected users should upgrade to OpenSSL 1.0.1g. Users unable to immediately upgrade can alternatively recompile OpenSSL with -DOPENSSL_NO_HEARTBEATS.
The bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop communications, steal data directly from the services and users and to impersonate services and users.
The code used to handle the Heartbeat Extension does not do sufficient boundary checks on record length, which allows reading beyond the actual payload.
The OTRS Project reports:
An attacker could embed OTRS in a hidden iframe tag of another page, tricking the user into clicking links in OTRS.
oCERT reports:
The LibYAML project is an open source YAML 1.1 parser and emitter written in C.
The library is affected by a heap-based buffer overflow which can lead to arbitrary code execution. The vulnerability is caused by lack of proper expansion for the string passed to the yaml_parser_scan_uri_escapes() function.
A specially crafted YAML file, with a long sequence of percent-encoded characters in a URL, can be used to trigger the overflow.

User's credentials are never leaked, but if a user tries to send an e-mail, the automatic saving into the "sent" or "draft" folders could happen over a plaintext connection even if the user's preferences specify STARTTLS as a requirement.
The nginx project reports:
A bug in the experimental SPDY implementation in nginx was found, which might allow an attacker to cause a heap memory buffer overflow in a worker process by using a specially crafted request, potentially resulting in arbitrary code execution (CVE-2014-0133).
The problem affects nginx 1.3.15 - 1.5.11, compiled with the ngx_http_spdy_module module (which is not compiled by default) and without --with-debug configure option, if the "spdy" option of the "listen" directive is used in a configuration file.
The problem is fixed in nginx 1.5.12, 1.4.7.

Beatrice Torracca and Evgeni Golov report:
A buffer overflow has been discovered that could result in denial of service or potential execution of arbitrary code.
This condition can be triggered by malformed RFC2047 header lines
JonApps reports:
The read-only mode can be bypassed and any command sent to bash session
Samba project reports:
In Samba's SAMR server we neglect to ensure that attempted password changes will update the bad password count, nor set the lockout flags. This would allow a user unlimited attempts against the password by simply calling ChangePasswordUser2 repeatedly.
This is available without any other authentication.
smbcacls can remove a file or directory ACL by mistake.
The Asterisk project reports:
Stack Overflow in HTTP Processing of Cookie Headers. Sending a HTTP request that is handled by Asterisk with a large number of Cookie headers could overflow the stack. You could even exhaust memory if you sent an unlimited number of headers in the request.
Denial of Service Through File Descriptor Exhaustion with chan_sip Session-Timers. An attacker can use all available file descriptors using SIP INVITE requests. Asterisk will respond with code 400, 420, or 422 for INVITEs meeting this criteria. Each INVITE meeting these conditions will leak a channel and several file descriptors. The file descriptors cannot be released without restarting Asterisk which may allow intrusion detection systems to be bypassed by sending the requests slowly.
Remote Crash Vulnerability in PJSIP channel driver. A remotely exploitable crash vulnerability exists in the PJSIP channel driver if the "qualify_frequency" configuration option is enabled on an AOR and the remote SIP server challenges for authentication of the resulting OPTIONS request. The response handling code wrongly assumes that a PJSIP endpoint will always be associated with an outgoing request which is incorrect.
Mateusz Jurczyk reports:
Out of bounds stack-based read/write in cf2_hintmap_build.
This is a critical vulnerability in the CFF Rasterizer code recently contributed by Adobe, leading to potential arbitrary code execution in the context of the FreeType2 library client.
Secunia reports:
Secunia Research has discovered two vulnerabilities in XMMS, which can be exploited by malicious people to compromise a user's system.
1) An integer underflow error exists in the processing of skin bitmap images. This can be exploited to cause a stack-based buffer overflow via specially crafted skin images containing manipulated header information.
Successful exploitation allows execution of arbitrary code.
2) An integer overflow error exists in the processing of skin bitmap images. This can be exploited to cause memory corruption via specially crafted skin images containing manipulated header information.
Successful exploitation may allow the execution of arbitrary code.
The nginx project reports:
A bug in the experimental SPDY implementation in nginx 1.5.10 was found, which might allow an attacker to corrupt worker process memory by using a specially crafted request, potentially resulting in arbitrary code execution (CVE-2014-0088).
The problem only affects nginx 1.5.10 on 32-bit platforms, compiled with the ngx_http_spdy_module module (which is not compiled by default), if the "spdy" option of the "listen" directive is used in a configuration file.
GnuTLS project reports:
A vulnerability was discovered that affects the certificate verification functions of all gnutls versions. A specially crafted certificate could bypass certificate validation checks. The vulnerability was discovered during an audit of GnuTLS for Red Hat.
Suman Jana reported a vulnerability that affects the certificate verification functions of gnutls 2.11.5 and later versions. A version 1 intermediate certificate will be considered as a CA certificate by default (something that deviates from the documented behavior).
The Fine Free file project reports:
file before 5.17 allows context-dependent attackers to cause a denial of service (infinite recursion, CPU consumption, and crash) via a crafted indirect offset value in the magic of a file.
Vincent Danen via Red Hat Issue Tracker reports:
A vulnerability was reported in Python's socket module, due to a boundary error within the sock_recvfrom_into() function, which could be exploited to cause a buffer overflow. This could be used to crash a Python application that uses the socket.recvfrom_info() function or, possibly, execute arbitrary code with the permissions of the user running vulnerable Python code.
This vulnerable function, socket.recvfrom_into(), was introduced in Python 2.5. Earlier versions are not affected by this flaw.
Subversion Project reports:
Subversion's mod_dav_svn Apache HTTPD server module will crash when it receives an OPTIONS request against the server root and Subversion is configured to handle the server root and SVNListParentPath is on. This can lead to a DoS. There are no known instances of this problem being exploited in the wild, but the details of how to exploit it have been disclosed on the Subversion development mailing list.
The OTRS Project reports:
An attacker could send a specially prepared HTML email to OTRS. If he can then trick an agent into following a special link to display this email, JavaScript code would be executed.
PostgreSQL Project reports:
This update fixes CVE-2014-0060, in which PostgreSQL did not properly enforce the WITH ADMIN OPTION permission for ROLE management. Before this fix, any member of a ROLE was able to grant others access to the same ROLE regardless if the member was given the WITH ADMIN OPTION permission. It also fixes multiple privilege escalation issues, including: CVE-2014-0061, CVE-2014-0062, CVE-2014-0063, CVE-2014-0064, CVE-2014-0065, and CVE-2014-0066. More information on these issues can be found on our security page and the security issue detail wiki page.
With this release, we are also alerting users to a known security hole that allows other users on the same machine to gain access to an operating system account while it is doing "make check": CVE-2014-0067. "Make check" is normally part of building PostgreSQL from source code. As it is not possible to fix this issue without causing significant issues to our testing infrastructure, a patch will be released separately and publicly. Until then, users are strongly advised not to run "make check" on machines where untrusted users have accounts.
The phpMyAdmin development team reports:

libyaml was prone to a heap overflow that could result in arbitrary code execution. Pkg uses libyaml to parse the package manifests in some cases. Pkg also used libyaml to parse the remote repository until 1.2.
RedHat Product Security Team reports on libyaml:
A heap-based buffer overflow flaw was found in the way libyaml parsed YAML tags. A remote attacker could provide a specially-crafted YAML document that, when parsed by an application using libyaml, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
Florian Weimer of the Red Hat Product Security Team reports:
Due to a missing check during assembly of the HTTP request line a long target server name in the PROXY-CONNECT address can cause a stack buffer overrun. Exploitation requires that the attacker is able to provide the target server name to the PROXY-CONNECT address in the command line. This can happen for example in scripts that receive data from untrusted sources.
The OTRS Project reports:
SQL injection issue
An attacker that managed to take over the session of a logged in customer could create tickets and/or send follow-ups to existing tickets due to missing challenge token checks.
The RT development team reports:
Versions of RT between 4.2.0 and 4.2.2 (inclusive) are vulnerable to a denial-of-service attack via the email gateway; any installation which accepts mail from untrusted sources is vulnerable, regardless of the permissions configuration inside RT. This vulnerability is assigned CVE-2014-1474.
This vulnerability is caused by poor parsing performance in the Email::Address::List module, which RT depends on. We recommend that affected users upgrade their version of Email::Address::List to v0.02 or above, which resolves the issue. Due to a communications mishap, the release on CPAN will temporarily appear as "unauthorized," and the command-line cpan client will hence not install it. We expect this to be resolved shortly; in the meantime, the release is also available from our server.
strongSwan Project reports:
A DoS vulnerability triggered by crafted IKEv1 fragmentation payloads was discovered in strongSwan's IKE daemon charon. All versions since 5.0.2 are affected.
A DoS vulnerability and potential authorization bypass triggered by a crafted ID_DER_ASN1_DN ID payload was discovered in strongSwan. All versions since 4.3.3 are affected.
A DoS vulnerability in strongSwan was discovered, which is triggered by XAuth usernames and EAP identities in versions 5.0.3 and 5.0.4.
Varnish Cache Project reports:
If Varnish receives a certain illegal request, and the subroutine 'vcl_error{}' restarts the request, the varnishd worker process will crash with an assert.
The varnishd management process will restart the worker process, but there will be a brief interruption of service and the cache will be emptied, causing more traffic to go to the backend.
We are releasing this advisory because restarting from vcl_error{} is both fairly common and documented.
This is purely a denial of service vulnerability, there is no risk of privilege escalation.
Workaround
Insert this at the top of your VCL file:
sub vcl_error { if (obj.status == 400 || obj.status == 413) { return(deliver); } } Or add this test at the top of your existing vcl_error{}.
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
Michael Sweet reports:

Oracle reports:
Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox prior to 3.2.20, 4.0.22, 4.1.30, 4.2.22, and 4.3.6 allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Core.
ntp.org reports:
Unrestricted access to the monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013
Use noquery to your default restrictions to block all status queries.
Use disable monitor to disable the ``ntpdc -c monlist'' command while still allowing other status queries.
Eric Stanley reports:
Most CGIs previously incremented the input variable counter twice when it encountered a long key value. This could cause the CGI to read past the end of the list of CGI variables.
ISC reports:
Because of a defect in handling queries for NSEC3-signed zones, BIND can crash with an "INSIST" failure in name.c when processing queries possessing certain properties. By exploiting this defect an attacker deliberately constructing a query with the right properties could achieve denial of service against an authoritative nameserver serving NSEC3-signed zones.
freedesktop.org reports:
A BDF font file containing a longer than expected string can cause a buffer overflow on the stack. Testing in X servers built with Stack Protector restulted in an immediate crash when reading a user-proveded specially crafted font.
As libXfont is used to read user-specified font files in all X servers distributed by X.Org, including the Xorg server which is often run with root privileges or as setuid-root in order to access hardware, this bug may lead to an unprivileged user acquiring root privileges in some systems.
OpenSSL development team reports:
Major changes between OpenSSL 1.0.1e and OpenSSL 1.0.1f [6 Jan 2014]:
- Fix for TLS record tampering bug [CVE-2013-4353]

- Fix for DTLS retransmission bug [CVE-2013-6450]
Revive reports:
An SQL-injection vulnerability was recently discovered and reported to the Revive Adserver team by Florian Sander. The vulnerability is known to be already exploited to gain unauthorised access to the application using brute force mechanisms, however other kind of attacks might be possible and/or already in use. The risk is rated to be critical as the most common end goal of the attackers is to spread malware to the visitors of all the websites and ad networks that the ad server is being used on.
The vulnerability is also present and exploitable in OpenX Source 2.8.11 and earlier versions, potentially back to phpAdsNew 2.0.x.
cURL project reports:
libcurl is vulnerable to a case of missing out the checking of the certificate CN or SAN name field when the digital signature verification is turned off.
libcurl offers two separate and independent options for verifying a server's TLS certificate. CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST. The first one tells libcurl to verify the trust chain using a CA cert bundle, while the second tells libcurl to make sure that the name fields in the server certificate meets the criteria. Both options are enabled by default.
This flaw had the effect that when an application disabled CURLOPT_SSL_VERIFYPEER, libcurl mistakenly also skipped the CURLOPT_SSL_VERIFYHOST check. Applications can disable CURLOPT_SSL_VERIFYPEER and still achieve security by doing the check on its own using other means.
The curl command line tool is not affected by this problem as it either enables both options or disables both at the same time.
Werner Koch reports:
CVE-2013-4576 has been assigned to this security bug.
The paper describes two attacks. The first attack allows to distinguish keys: An attacker is able to notice which key is currently used for decryption. This is in general not a problem but may be used to reveal the information that a message, encrypted to a commonly not used key, has been received by the targeted machine. We do not have a software solution to mitigate this attack.
The second attack is more serious. It is an adaptive chosen ciphertext attack to reveal the private key. A possible scenario is that the attacker places a sensor (for example a standard smartphone) in the vicinity of the targeted machine. That machine is assumed to do unattended RSA decryption of received mails, for example by using a mail client which speeds up browsing by opportunistically decrypting mails expected to be read soon. While listening to the acoustic emanations of the targeted machine, the smartphone will send new encrypted messages to that machine and re-construct the private key bit by bit. A 4096 bit RSA key used on a laptop can be revealed within an hour.
The Asterisk project reports:
A 16 bit SMS message that contains an odd message length value will cause the message decoding loop to run forever. The message buffer is not on the stack but will be overflowed resulting in corrupted memory and an immediate crash.
External control protocols, such as the Asterisk Manager Interface, often have the ability to get and set channel variables; this allows the execution of dialplan functions. Dialplan functions within Asterisk are incredibly powerful, which is wonderful for building applications using Asterisk. But during the read or write execution, certain diaplan functions do much more. For example, reading the SHELL() function can execute arbitrary commands on the system Asterisk is running on. Writing to the FILE() function can change any file that Asterisk has write access to. When these functions are executed from an external protocol, that execution could result in a privilege escalation.
The phpMyFAQ team reports:
Secunia noticed while analysing the advisory that authenticated users with "Right to add attachments" are able to exploit an already publicly known issue in the bundled Ajax File Manager of phpMyFAQ version 2.8.3, which leads to arbitrary PHP code execution for authenticated users with the permission "Right to add attachments".
Recurity Labs Team project reports:
Zabbix agent is vulnerable to remote command execution from the Zabbix server in some cases.
Stefan Esser reports:
The PHP function openssl_x509_parse() uses a helper function called asn1_time_to_time_t() to convert timestamps from ASN1 string format into integer timestamp values. The parser within this helper function is not binary safe and can therefore be tricked to write up to five NUL bytes outside of an allocated buffer.
This problem can be triggered by x509 certificates that contain NUL bytes in their notBefore and notAfter timestamp fields and leads to a memory corruption that might result in arbitrary code execution.
Depending on how openssl_x509_parse() is used within a PHP application the attack requires either a malicious cert signed by a compromised/malicious CA or can be carried out with a self-signed cert.

The OpenTTD Team reports:
The problem is caused by incorrectly handling the fact that the aircraft circling the corner airport will be outside of the bounds of the map. In the 'out of fuel' crash code the height of the tile under the aircraft is determined. In this case that means a tile outside of the allocated map array, which could occasionally trigger invalid reads.
Monitorix Project reports:
A serious bug in the built-in HTTP server. It was discovered that the handle_request() routine did not properly perform input sanitization which led into a number of security vulnerabilities. An unauthenticated, remote attacker could exploit this flaw to execute arbitrary commands on the remote host. All users still using older versions are advised to upgrade to this version, which resolves this issue.
Subversion Project reports:
mod_dontdothat does not restrict requests from serf based clients
mod_dontdothat allows you to block update REPORT requests against certain paths in the repository. It expects the paths in the REPORT request to be absolute URLs. Serf based clients send relative URLs instead of absolute URLs in many cases. As a result these clients are not blocked as configured by mod_dontdothat.
mod_dav_svn assertion triggered by non-canonical URLs in autoversioning commits
When SVNAutoversioning is enabled via SVNAutoversioning on commits can be made by single HTTP requests such as MKCOL and PUT. If Subversion is built with assertions enabled any such requests that have non-canonical URLs, such as URLs with a trailing /, may trigger an assert. An assert will cause the Apache process to abort.
Ruby Gem developers report:
The patch for CVE-2013-4363 was insufficiently verified so the combined regular expression for verifying gem version remains vulnerable following CVE-2013-4363.
RubyGems validates versions with a regular expression that is vulnerable to denial of service due to backtracking. For specially crafted RubyGems versions attackers can cause denial of service through CPU consumption.
Ruby Gem developers report:
RubyGems validates versions with a regular expression that is vulnerable to denial of service due to backtracking. For specially crafted RubyGems versions attackers can cause denial of service through CPU consumption.
Ruby developers report:
Any time a string is converted to a floating point value, a specially crafted string can cause a heap overflow. This can lead to a denial of service attack via segmentation faults and possibly arbitrary code execution. Any program that converts input of unknown origin to floating point values (especially common when accepting JSON) are vulnerable.
The Samba project reports:
Samba 4.0.x before 4.0.11 and 4.1.x before 4.1.1, when LDAP or HTTP is provided over SSL, uses world-readable permissions for a private key, which allows local users to obtain sensitive information by reading the key file, as demonstrated by access to the local filesystem on an AD domain controller.
The Samba project reports:
Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x, 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying file or directory ACL when opening an alternate data stream.
According to the SMB1 and SMB2+ protocols the ACL on an underlying file or directory should control what access is allowed to alternate data streams that are associated with the file or directory.
The nginx project reports:
Ivan Fratric of the Google Security Team discovered a bug in nginx, which might allow an attacker to bypass security restrictions in certain configurations by using a specially crafted request, or might have potential other impact (CVE-2013-4547).
Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
The OpenSSH development team reports:
A memory corruption vulnerability exists in the post- authentication sshd process when an AES-GCM cipher (aes128-gcm@openssh.com or aes256-gcm@openssh.com) is selected during kex exchange.
If exploited, this vulnerability might permit code execution with the privileges of the authenticated user and may therefore allow bypassing restricted shell/command configurations.
Either upgrade to 6.4 or disable AES-GCM in the server configuration. The following sshd_config option will disable AES-GCM while leaving other ciphers active:
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,aes192-cbc,aes256-cbc
Quassel IRC developers report:

Various versions of mod_pagespeed are subject to critical cross-site scripting (XSS) vulnerability, CVE-2013-6111. This permits a hostile third party to execute JavaScript in users' browsers in context of the domain running mod_pagespeed, which could permit theft of users' cookies or data on the site.
Salvatore Bonaccorso reports:
This vulnerability affects the DANE library of gnutls 3.1.x and gnutls 3.2.x. A server that returns more 4 DANE entries could corrupt the memory of a requesting client.
Alan Coopersmith reports:
Pedro Ribeiro (pedrib at gmail.com) reported an issue to the X.Org security team in which an authenticated X client can cause an X server to use memory after it was freed, potentially leading to crash and/or memory corruption.
Dwayne Litzenberger reports:
In PyCrypto before v2.6.1, the Crypto.Random pseudo-random number generator (PRNG) exhibits a race condition that may cause it to generate the same 'random' output in multiple processes that are forked from each other. Depending on the application, this could reveal sensitive information or cryptographic keys to remote attackers.
The wordpress development team reports:
- Block unsafe PHP unserialization that could occur in limited situations and setups, which can lead to remote code execution.
- Prevent a user with an Author role, using a specially crafted request, from being able to create a post "written by" another user.
- Fix insufficient input validation that could result in redirecting or leading a user to another website.
Additionally, we've adjusted security restrictions around file uploads to mitigate the potential for cross-site scripting.
node.js developers report
This release contains a security fix for the http server implementation, please upgrade as soon as possible.
Cross-Site Request Forgery
When a user submits changes to a bug right after another user did, a midair collision page is displayed to inform the user about changes recently made. This page contains a token which can be used to validate the changes if the user decides to submit his changes anyway. A regression in Bugzilla 4.4 caused this token to be recreated if a crafted URL was given, even when no midair collision page was going to be displayed, allowing an attacker to bypass the token check and abuse a user to commit changes on his behalf.
Cross-Site Request Forgery
When an attachment is edited, a token is generated to validate changes made by the user. Using a crafted URL, an attacker could force the token to be recreated, allowing him to bypass the token check and abuse a user to commit changes on his behalf.
Cross-Site Scripting
Some parameters passed to editflagtypes.cgi were not correctly filtered in the HTML page, which could lead to XSS.
Cross-Site Scripting
Due to an incomplete fix for CVE-2012-4189, some incorrectly filtered field values in tabular reports could lead to XSS.
The Dropbear project reports:
A weakness and a vulnerability have been reported in Dropbear SSH Server, which can be exploited by malicious people to disclose certain sensitive information and cause a DoS.

Werner Koch reports:
Special crafted input data may be used to cause a denial of service against GPG (GnuPG's OpenPGP part) and some other OpenPGP implementations. All systems using GPG to process incoming data are affected..
xinetd would execute configured TCPMUX services without dropping privilege to match the service configuration allowing the service to run with same privilege as the xinetd process (root).
PolarSSL Project reports:
The researchers Cyril Arnaud and Pierre-Alain Fouque investigated the PolarSSL RSA implementation and discovered a bias in the implementation of the Montgomery multiplication that we used. For which they then show that it can be used to mount an attack on the RSA key. Although their test attack is done on a local system, there seems to be enough indication that this can properly be performed from a remote system as well.
All versions prior to PolarSSL 1.2.9 and 1.3.0 are affected if a third party can send arbitrary handshake messages to your server.
If correctly executed, this attack reveals the entire private RSA key after a large number of attack messages (> 600.000 on a local machine) are sent to show the timing differences.
Graphite developers report:
This release contains several security fixes for cross-site scripting (XSS) as well as a fix for a remote-execution exploit in graphite-web (CVE-2013-5903).
The Django project reports:
These releases address a denial-of-service attack against Django's authentication framework. All users of Django are encouraged to upgrade immediately.
Problem Description:
The nullfs(5) implementation of the VOP_LINK(9) VFS operation does not check whether the source and target of the link are both in the same nullfs instance. It is therefore possible to create a hardlink from a location in one nullfs instance to a file in another, as long as the underlying (source) filesystem is the same.
Impact:
If multiple nullfs views into the same filesystem are mounted in different locations, a user with read access to one of these views and write access to another will be able to create a hard link from the latter to a file in the former, even though they are, from the user's perspective, different filesystems. The user may thereby gain write access to files which are nominally on a read-only filesystem.
Problem Description:
As is commonly the case, the IPv6 and ATM network layer ioctl request handlers are written in such a way that an unrecognized request is passed on unmodified to the link layer, which will either handle it or return an error code.
Network interface drivers, however, assume that the SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR and SIOCSIFNETMASK requests have been handled at the network layer, and therefore do not perform input validation or verify the caller's credentials. Typical link-layer actions for these requests may include marking the interface as "up" and resetting the underlying hardware.
Impact:
An unprivileged user with the ability to run arbitrary code can cause any network interface in the system to perform the link layer actions associated with a SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR or SIOCSIFNETMASK ioctl request; or trigger a kernel panic by passing a specially crafted address structure which causes a network interface driver to dereference an invalid pointer.
Although this has not been confirmed, the possibility that an attacker may be able to execute arbitrary code in kernel context can not be ruled out.

Adobe reports:
These updates address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system.
The Django project reports:
These releases address a directory-traversal vulnerability in one of Django's built-in template tags. While this issue requires some fairly specific factors to be exploitable, we encourage all users of Django to upgrade promptly.
Subversion Project reports:
svnserve takes a --pid-file option which creates a file containing the process id it is running as. It does not take steps to ensure that the file it has been directed at is not a symlink. If the pid file is in a directory writeable by unprivileged users, the destination could be replaced by a symlink allowing for privilege escalation. svnserve does not create a pid file by default.
All versions are only vulnerable when the --pid-file=ARG option is used.
Cacti release reports:
Multiple security vulnerabilities have been fixed:
- SQL injection vulnerabilities
The Asterisk project reports:
Remote Crash From Late Arriving SIP ACK With SDP
Remote Crash when Invalid SDP is sent in SIP Request
Bundled version of libav in gstreamer-ffmpeg contains a number of vulnerabilities.
Werner Koch of the GNU project reports:
Noteworthy changes in version 1.5.3:
Mitigate the Yarom/Falkner flush+reload side-channel attack on RSA secret keys...
Note that Libgcrypt is used by GnuPG 2.x and thus this release fixes the above problem. The fix for GnuPG less than 2.0 can be found in the just released GnuPG 1.4.14.
Puppet Labs reports:
By using the `resource_type` service, an attacker could cause puppet to load arbitrary Ruby files from the puppet master node's file system. While this behavior is not enabled by default, `auth.conf` settings could be modified to allow it. The exploit requires local file system access to the Puppet Master.
Puppet Module Tool (PMT) did not correctly control permissions of modules it installed, instead transferring permissions that existed when the module was built.
Mageia security team reports:
It was discovered that Little CMS did not properly verify certain memory allocations. If a user or automated system using Little CMS were tricked into opening a specially crafted file, an attacker could cause Little CMS to crash (CVE-2013-4160).
Paul Bakker reports:
A bug in the logic of the parsing of PEM encoded certificates in x509parse_crt() can result in an infinite loop, thus hogging processing power.
While parsing a Certificate message during the SSL/TLS handshake, PolarSSL extracts the presented certificates and sends them on to be parsed. As the RFC specifies that the certificates in the Certificate message are always X.509 certificates in DER format, bugs in the decoding of PEM certificates should normally not be triggerable via the SSL/TLS handshake.
Versions of PolarSSL prior to 1.1.7 in the 1.1 branch and prior to 1.2.8 in the 1.2 branch call the generic x509parse_crt() function for parsing during the handshake. x509parse_crt() is a generic functions that wraps parsing of both PEM-encoded and DER-formatted certificates. As a result it is possible to craft a Certificate message that includes a PEM encoded certificate in the Certificate message that triggers the infinite loop.
The Samba project reports:
All current released versions of Samba are vulnerable to a denial of service on an authenticated or guest connection. A malformed packet can cause the smbd server to loop the CPU performing memory allocations and preventing any further service.
A connection to a file share, or a local account is needed to exploit this problem, either authenticated or unauthenticated if guest connections are allowed.

Simon Tatham reports:
This [0.63] release fixes multiple security holes in previous versions of PuTTY, which can allow an SSH-2 server to make PuTTY overrun or underrun buffers and crash. [...]
These vulnerabilities can be triggered before host key verification, which means that you are not even safe if you trust the server you think you're connecting to, since it could be spoofed over the network and the host key check would not detect this before the attack could take place.
Additionally, when PuTTY authenticated with a user's private key, the private key or information equivalent to it was accidentally kept in PuTTY's memory for the rest of its run, where it could be retrieved by other processes reading PuTTY's memory, or written out to swap files or crash dumps. This release fixes that as well.
Typo Security Team reports:
It has been discovered that TYPO3 Core is vulnerable to Cross-Site Scripting and Remote Code Execution.
TYPO3 bundles flash files for video and audio playback. Old versions of FlowPlayer and flashmedia are susceptible to Cross-Site Scripting. No authentication is required to exploit this vulnerability.
The file upload component and the File Abstraction Layer are failing to check for denied file extensions, which allows authenticated editors (even with limited permissions) to upload php files with arbitrary code, which can then be executed in web server's context.
The phpMyAdmin development team reports:
phpMyAdmin has a number of mechanisms to avoid a clickjacking attack, however these mechanisms either work only in modern browser versions, or can be bypassed.
"We have no solution for 3.5.x, due to the proposed solution requiring JavaScript. We don't want to introduce a dependency to JavaScript in the 3.5.x family."
The phpMyAdmin development team reports:
XSS due to unescaped HTML Output when executing a SQL query.
5 XSS vulnerabilities in setup, chart display, process list, and logo link.
If a crafted version.json would be presented, an XSS could be introduced.
Full path disclosure vulnerabilities.
XSS vulnerability when a text to link transformation is used.
Self-XSS due to unescaped HTML output in schema export.
SQL injection vulnerabilities, producing a privilege escalation (control user).
The wordpress development team reports:

ISC reports:
A specially crafted query that includes malformed rdata can cause named to terminate with an assertion failure while rejecting the malformed query.
A Yarom and Falkner paper reports:
Flush+Reload is a cache side-channel attack that monitors access to data in shared pages. In this paper we demonstrate how to use the attack to extract private encryption keys from GnuPG. The high resolution and low noise of the Flush+Reload attack enables a spy program to recover over 98% of the bits of the private key in a single decryption or signing round. Unlike previous attacks, the attack targets the last level L3 cache. Consequently, the spy program and the victim do not need to share the execution core of the CPU. The attack is not limited to a traditional OS and can be used in a virtualised environment, where it can attack programs executing in a different VM.
OpenAFS Project reports:
The small size of the DES key space permits an attacker to brute force a cell's service key and then forge traffic from any user within the cell. The key space search can be performed in under 1 day at a cost of around $100 using publicly available services.
Subversion Project reports:
Subversion's mod_dav_svn Apache HTTPD server module will trigger an assertion on some requests made against a revision root. This can lead to a DoS. If assertions are disabled it will trigger a read overflow which may cause a SEGFAULT (or equivalent) or undefined behavior.
Commit access is required to exploit this.
