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.
Net::FTP#get,getbinaryfile,gettextfile,put,putbinaryfile, andputtextfileuseKernel#opento open a local file. If thelocalfileargument starts with the pipe character"|", the command following the pipe character is executed. The default value oflocalfileisFile.basename(remotefile), so malicious FTP servers could cause arbitrary command execution.
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.

The scp_v0s_accept function in the session manager uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.
The cURL project reports:
- 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.
Oracle reports:

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.
Ruby blog:
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

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.

When under stress, closing many connections, the HTTP/2 handling code would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.important: Uninitialized memory reflection in mod_auth_digest (CVE-2017-9788)
The value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments. by mod_auth_digest.
Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault.

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).

This may, in some cases, enable bypass of capath policy in Heimdal versions 1.5 through 7.2. Note, this may break sites that rely on the bug. With the bug some incomplete [capaths] worked, that should not have. These may now break authentication in some cross-realm configurations. (CVE-2017-6594)
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.

GitLab reports:
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.
Accounts with email set to "Do not show on profile" have addresses exposed in public atom feed
Several GitLab users reported that even with "Do not show on profile" configured for their email addresses those addresses were still being leaked in Atom feeds if they commented on a public project.

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.

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).

httpd: fix two buffer overflows in IcyMetaData length calculation
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.

PHPMailer is prone to an local information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in launching further attacks.
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.

National Vulnerability Database:
There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. The session id itself may be generated randomly, but the way the session is indexed by the backing store does not use a secure comparison.

Typo3 core team reports:
It has been discovered that the output of field validation errors in the Form Framework is vulnerable to cross-site scripting.
It has been discovered that t3:// URL handling and typolink functionality are vulnerable to cross-site scripting. Not only regular backend forms are affected but also frontend extensions which use the rendering with typolink.
It has been discovered that the output table listing in the Files backend module is vulnerable to cross-site scripting when a file extension contains malicious sequences. Access to the file system of the server - either directly or through synchronization - is required to exploit the vulnerability.
It has been discovered that the extraction of manually uploaded ZIP archives in Extension Manager is vulnerable to directory traversal. Admin privileges are required in order to exploit this vulnerability. Since TYPO3 v9 LTS, System Maintainer privileges are required as well.
Failing to properly escape user submitted content, class QueryGenerator is vulnerable to SQL injection. Having system extension ext:lowlevel installed and a valid backend user having administrator privileges are required to exploit this vulnerability.
It has been discovered that classes QueryGenerator and QueryView are vulnerable to insecure deserialization. Requirements for successfully exploiting this vulnerability (one of the following): - having system extension ext:lowlevel (Backend Module: DB Check) installed and valid backend user having administrator privileges - having system extension ext:sys_action installed and valid backend user having limited privileges
TYPO3 allows to upload files either in the backend user interface as well as in custom developed extensions. To reduce the possibility to upload potential malicious code TYPO3 uses the fileDenyPattern to deny e.g. user submitted PHP scripts from being persisted. Besides that it is possible for any editor to upload file assets using the file module (fileadmin) or changing their avatar image shown in the TYPO3 backend. Per default TYPO3 allows to upload and store HTML and SVG files as well using the mentioned functionalities. Custom extension implementations probably would also accept those files when only the fileDenyPattern is evaluated. Since HTML and SVG files - which might contain executable JavaScript code per W3C standard - could be directly displayed in web clients, the whole web application is exposed to be vulnerable concerning Cross-Site Scripting. Currently the following scenarios are known - given an authenticated regular editor is able to upload files using the TYPO3 backend: - directly target a potential victim to a known public resource in a URL, e.g. /fileadmin/malicious.svg or /fileadmin/malicious.html - using the TypoScript content object “SVG” (implemented in class ScalableVectorGraphicsContentObject) having renderMode set to inline for SVG files (available since TYPO3 v9.0) - custom implementations that directly output and render markup of HTML and SVG files SVG files that are embedded using an img src=”malicious.svg” tag are not vulnerable since potential scripts are not executed in these scenarios (see https://www.w3.org/wiki/SVG_Security). The icon API of TYPO3 is not scope of this announcement since SVG icons need to be registered using an individual implementation, which is not considered as user submitted content.
It has been discovered that request handling in Extbase can be vulnerable to insecure deserialization. User submitted payload has to be signed with a corresponding HMAC-SHA1 using the sensitive TYPO3 encryptionKey as secret - invalid or unsigned payload is not deserialized. However, since sensitive information could have been leaked by accident (e.g. in repositories or in commonly known and unprotected backup files), there is the possibility that attackers know the private encryptionKey and are able to calculate the required HMAC-SHA1 to allow a malicious payload to be deserialized. Requirements for successfully exploiting this vulnerability (all of the following): - rendering at least one Extbase plugin in the frontend - encryptionKey has been leaked (from LocalConfiguration.php or corresponding .env file).
Ted Y. Ts'o reports:
A maliciously corrupted file systems can trigger buffer overruns in the quota code used by e2fsck.
Drupal Security Team reports:
A visit to install.php can cause cached data to become corrupted. This could cause a site to be impaired until caches are rebuilt.
Drupal 8 core's file_save_upload() function does not strip the leading and trailing dot ('.') from filenames, like Drupal 7 did. Users with the ability to upload files with any extension in conjunction with contributed modules may be able to use this to upload system files such as .htaccess in order to bypass protections afforded by Drupal's default .htaccess file. After this fix, file_save_upload() now trims leading and trailing dots from filenames.
The Media Library module has a security vulnerability whereby it doesn't sufficiently restrict access to media items in certain configurations.
The Drupal project uses the third-party library Archive_Tar, which has released a security-related feature that impacts some Drupal configurations. Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them. The latest versions of Drupal update Archive_Tar to 1.4.9 to mitigate the file processing vulnerabilities.

The OpenSSL project reports:
rsaz_512_sqr overflow bug on x86_64 (CVE-2019-1551) (Low)
There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME.

Django release reports:
CVE-2019-19118: Privilege escalation in the Django admin.
Since Django 2.1, a Django model admin displaying a parent model with related model inlines, where the user has view-only permissions to a parent model but edit permissions to the inline model, would display a read-only view of the parent model but editable forms for the inline.
Submitting these forms would not allow direct edits to the parent model, but would trigger the parent model's save() method, and cause pre and post-save signal handlers to be invoked. This is a privilege escalation as a user who lacks permission to edit a model should not be able to trigger its save-related signals.

The WebKitGTK project reports multiple vulnerabilities.
NIST reports: (by search in the range 2018/01/01 - 2019/11/10):
urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext.
In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.
The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument.
Starting with version 1.26, the devcpu-data port/package includes updates and mitigations for the following technical and security advisories (depending on CPU model).
Intel TSX Updates (TAA) CVE-2019-11135 Voltage Modulation Vulnerability CVE-2019-11139 MD_CLEAR Operations CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2018-11091 TA Indirect Sharing CVE-2017-5715 EGETKEY CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2018-11091 JCC SKX102 Erratum
Updated microcode includes mitigations for CPU issues, but may also cause a performance regression due to the JCC erratum mitigation. Please visit http://www.intel.com/benchmarks for further information.
Please visit http://www.intel.com/security for detailed information on these advisories as well as a list of CPUs that are affected.
Operating a CPU without the latest microcode may result in erratic or unpredictable behavior, including system crashes and lock ups. Certain issues listed in this advisory may result in the leakage of privileged system information to unprivileged users. Please refer to the security advisories listed above for detailed information.
Intel discovered a previously published erratum on some Intel platforms can be exploited by malicious software to potentially cause a denial of service by triggering a machine check that will crash or hang the system.
Malicious guest operating systems may be able to crash the host.
Micah Snyder reports:
A Denial-of-Service (DoS) vulnerability may occur when scanning a specially crafted email file as a result of excessively long scan times. The issue is resolved by implementing several maximums in parsing MIME messages and by optimizing use of memory allocation.
Unbound Security Advisories:
Recent versions of Unbound contain a vulnerability that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with --enable-ipsecmod support, and ipsecmod is enabled and used in the configuration.
The Gitea Team reports:
This release contains five security fixes, so we recommend updating:
- Fix issue with user.fullname
- Ignore mentions for users with no access
- Be more strict with git arguments
- Extract the username and password from the mirror url
- Reserve .well-known username
The Asterisk project reports:
If Asterisk receives a re-invite initiating T.38 faxing and has a port of 0 and no c line in the SDP, a crash will occur.
The Asterisk project reports:
A remote authenticated Asterisk Manager Interface (AMI) user without system authorization could use a specially crafted Originate AMI request to execute arbitrary system commands.
The Asterisk project reports:
A SIP request can be sent to Asterisk that can change a SIP peers IP address. A REGISTER does not need to occur, and calls can be hijacked as a result. The only thing that needs to be known is the peers name; authentication details such as passwords do not need to be known. This vulnerability is only exploitable when the nat option is set to the default, or auto_force_rport.
Intel reports:
As part of IPU 2019.2, INTEL-SA-00242 advises that insufficient access control may allow an authenticated user to potentially enable escalation of privilege via local access.
INTEL-SA-00260 advises that insufficient access control may allow an authenticated user to potentially enable denial of service via local access.
Squid Team reports:
Problem Description: Due to incorrect data management Squid is vulnerable to a information disclosure when processing HTTP Digest Authentication.
Severity: Nonce tokens contain the raw byte value of a pointer which sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.
CVE list:
GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels. This makes it possible in some circumstances for one domain to impersonate another. By creating a malicious domain that matches a target domain except for the inclusion of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label and then back to an ASCII label), arbitrary domains can be impersonated.

System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file.
A local user can use this flaw to obtain access to files, directories, sockets, etc., opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.
The kernel driver for /dev/midistat implements a handler for read(2). This handler is not thread-safe, and a multi-threaded program can exploit races in the handler to cause it to copy out kernel memory outside the boundaries of midistat's data buffer.
The races allow a program to read kernel memory within a 4GB window centered at midistat's data buffer. The buffer is allocated each time the device is opened, so an attacker is not limited to a static 4GB region of memory.
On 32-bit platforms, an attempt to trigger the race may cause a page fault in kernel mode, leading to a panic.
Due do a missing check in the code of m_pulldown(9) data returned may not be contiguous as requested by the caller.
Extra checks in the IPv6 code catch the error condition and trigger a kernel panic leading to a remote DoS (denial-of-service) attack with certain Ethernet interfaces. At this point it is unknown if any other than the IPv6 code paths can trigger a similar condition.
The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets.
When TCP segmentation offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to determine the size of the on-stack buffer without validation. The subsequent header generation could overflow an incorrectly sized buffer or indirect a pointer composed of stack garbage.
A misbehaving bhyve guest could overwrite memory in the bhyve process on the host.
A function extracting the length from type-length-value encoding is not properly validating the submitted length.
A remote user could cause, for example, an out-of-bounds read, decoding of unrelated data, or trigger a crash of the software such as bsnmpd resulting in a denial of service.
The ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs.
A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.
The decompressor used in bzip2 contains a bug which can lead to an out-of-bounds write when processing a specially crafted bzip2(1) file.
bzip2recover contains a heap use-after-free bug which can be triggered when processing a specially crafted bzip2(1) file.
An attacker who can cause maliciously crafted input to be processed may trigger either of these bugs. The bzip2recover bug may cause a crash, permitting a denial-of-service. The bzip2 decompressor bug could potentially be exploited to execute arbitrary code.
Note that some utilities, including the tar(1) archiver and the bspatch(1) binary patching utility (used in portsnap(8) and freebsd-update(8)) decompress bzip2(1)-compressed data internally; system administrators should assume that their systems will at some point decompress bzip2(1)-compressed data even if they never explicitly invoke the bunzip2(1) utility.
Varnish Software reports:
A bug has been discovered in Varnish Cache where we fail to clear a pointer between the handling of one client requests and the next on the same connection. This can under specific circumstances lead to information being leaked from the connection workspace.
Todd C. Miller reports:
When sudo is configured to allow a user to run commands as an arbitrary user via the ALL keyword in a Runas specification, it is possible to run commands as root by specifying the user ID -1 or 4294967295.
This can be used by a user with sufficient sudo privileges to run commands as root even if the Runas specification explicitly disallows root access as long as the ALL keyword is listed first in the Runas specification.
Log entries for commands run this way will list the target user as 4294967295 instead of root. In addition, PAM session modules will not be run for the command.

mod_perl2 2.0.11 fixes Arbitrary Perl code execution in the context of the user account via a user-owned .htaccess.
mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.

Exim developers team report:
There is a heap overflow in string_vformat().Using a EHLO message, remote code execution seems to be possible.
The Go project reports:
net/http (through net/textproto) used to accept and normalize invalid HTTP/1.1 headers with a space before the colon, in violation of RFC 7230. If a Go server is used behind a reverse proxy that accepts and forwards but doesn't normalize such invalid headers, the reverse proxy and the server can interpret the headers differently. This can lead to filter bypasses or request smuggling, the latter if requests from separate clients are multiplexed onto the same connection by the proxy. Such invalid headers are now rejected by Go servers, and passed without normalization to Go client applications.

Janos Follath reports:
Mbed TLS does not have a constant-time/constant-trace arithmetic library and uses blinding to protect against side channel attacks.
In the ECDSA signature routine previous Mbed TLS versions used the same RNG object for generating the ephemeral key pair and for generating the blinding values. The deterministic ECDSA function reused this by passing the RNG object created from the private key and the message to be signed as prescribed by RFC 6979. This meant that the same RNG object was used whenever the same message was signed, rendering the blinding ineffective.
If the victim can be tricked to sign the same message repeatedly, the private key may be recoverable through side channels.
Jon Siwek of Corelight reports:
This is a security patch release to address a potential Denial of Service vulnerability:
- The NTLM analyzer did not properly handle AV Pair sequences that were either empty or unterminated, resulting in invalid memory access or heap buffer over-read. The NTLM analyzer is enabled by default and used in the analysis of SMB, DCE/RPC, and GSSAPI protocols.
expat project reports:
XML names with multiple colons could end up in the wrong namespace, and take a high amount of RAM and CPU resources while processing, opening the door to use for denial-of-service attacks
curl security problems:
CVE-2019-5481: FTP-KRB double-free
libcurl can be told to use kerberos over FTP to a server, as set with the CURLOPT_KRBLEVEL option.
During such kerberos FTP data transfer, the server sends data to curl in blocks with the 32 bit size of each block first and then that amount of data immediately following.
A malicious or just broken server can claim to send a very large block and if by doing that it makes curl's subsequent call to realloc() to fail, curl would then misbehave in the exit path and double-free the memory.
In practical terms, an up to 4 GB memory area may very well be fine to allocate on a modern 64 bit system but on 32 bit systems it will fail.
Kerberos FTP is a rarely used protocol with curl. Also, Kerberos authentication is usually only attempted and used with servers that the client has a previous association with.
CVE-2019-5482: TFTP small blocksize heap buffer overflow
libcurl contains a heap buffer overflow in the function (tftp_receive_packet()) that receives data from a TFTP server. It can call recvfrom() with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is controlled by the server.
This flaw is only triggered if the TFTP server sends an OACK without the BLKSIZE option, when a BLKSIZE smaller than 512 bytes was requested by the TFTP client. OACK is a TFTP extension and is not used by all TFTP servers.
Users choosing a smaller block size than default should be rare as the primary use case for changing the size is to make it larger.
It is rare for users to use TFTP across the Internet. It is most commonly used within local networks. TFTP as a protocol is always inherently insecure.
This issue was introduced by the add of the TFTP BLKSIZE option handling. It was previously incompletely fixed by an almost identical issue called CVE-2019-5436.
The OpenSSL project reports:
ECDSA remote timing attack (CVE-2019-1547) [Low]
Fork Protection (CVE-2019-1549) [Low]

Adobe reports:
- This update resolves a same origin method execution vulnerability that could lead to arbitrary code execution (CVE-2019-8069).
- This update resolves a use-after-free vulnerability that could lead to arbitrary code execution (CVE-2019-8070).
A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onig_new_deluxe().
A NULL Pointer Dereference in match_at() in regexec.c in Oniguruma 6.9.2 allows attackers to potentially cause denial of service by providing a crafted regular expression.
Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust.

In addition to the above changes, we are also updating jQuery on older versions of WordPress. This change was added in 5.2.1 and is now being brought to older versions.
Exim developers report:
If your Exim server accepts TLS connections, it is vulnerable. This does not depend on the TLS libray, so both, GnuTLS and OpenSSL are affected.
The vulnerability is exploitable by sending a SNI ending in a backslash-null sequence during the initial TLS handshake. The exploit exists as a POC. For more details see the document qualys.mbx
The Asterisk project reports:
When audio frames are given to the audio transcoding support in Asterisk the number of samples are examined and as part of this a message is output to indicate that no samples are present. A change was done to suppress this message for a particular scenario in which the message was not relevant. This change assumed that information about the origin of a frame will always exist when in reality it may not.
This issue presented itself when an RTP packet containing no audio (and thus no samples) was received. In a particular transcoding scenario this audio frame would get turned into a frame with no origin information. If this new frame was then given to the audio transcoding support a crash would occur as no samples and no origin information would be present. The transcoding scenario requires the genericplc option to be set to enabled (the default) and a transcoding path from the source format into signed linear and then from signed linear into another format.
Note that there may be other scenarios that have not been found which can cause an audio frame with no origin to be given to the audio transcoding support and thus cause a crash.
The Asterisk project reports:
When Asterisk sends a re-invite initiating T.38 faxing, and the endpoint responds with a declined media stream a crash will then occur in Asterisk.

Ruby news:
There are multiple vulnerabilities about Cross-Site Scripting (XSS) in jQuery shipped with RDoc which bundled in Ruby. All Ruby users are recommended to update Ruby to the latest release which includes the fixed version of RDoc.
The following vulnerabilities have been reported.
CVE-2012-6708
CVE-2015-9251
Aki Tuomi reports:
Vulnerability Details: IMAP and ManageSieve protocol parsers do not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes. Risk: This vulnerability allows for out-of-bounds writes to objects stored on the heap up to 8096 bytes in pre-login phase, and 65536 bytes post-login phase, allowing sufficiently skilled attacker to perform complicated attacks that can lead to leaking private information or remote code execution. Abuse of this bug is very difficult to observe, as it does not necessarily cause a crash. Attempts to abuse this bug are not directly evident from logs.

Jonathon Loomey of Netflix reports:
HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion
Recently, a series of DoS attack vulnerabilities have been reported on a broad range of HTTP/2 stacks. Among the vulnerabilities, H2O is exposed to the following:
- CVE-2019-9512 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9514 "Reset Flood": The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
- CVE-2019-9515 "Settings Flood": The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

The Gitea Team reports:
This release contains two security fixes, so we highly recommend updating.
Micah Snyder reports:
- An out of bounds write was possible within ClamAV&s NSIS bzip2 library when attempting decompression in cases where the number of selectors exceeded the max limit set by the library (CVE-2019-12900). The issue has been resolved by respecting that limit.
- The zip bomb vulnerability mitigated in 0.101.3 has been assigned the CVE identifier CVE-2019-12625. Unfortunately, a workaround for the zip-bomb mitigation was immediately identified. To remediate the zip-bomb scan time issue, a scan time limit has been introduced in 0.101.4. This limit now resolves ClamAV's vulnerability to CVE-2019-12625.
Node.js reports:
Node.js, as well as many other implementations of HTTP/2, have been found vulnerable to Denial of Service attacks. See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for more information.
Updates are now available for all active Node.js release lines, including Linux ARMv6 builds for Node.js 8.x (which had been delayed).
We recommend that all Node.js users upgrade to a version listed below as soon as possible.
Vulnerabilities Fixed
Impact: All versions of Node.js 8 (LTS "Carbon"), Node.js 10 (LTS "Dubnium"), and Node.js 12 (Current) are vulnerable to the following:
- CVE-2019-9511 "Data Dribble": The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9512 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9513 "Resource Loop": The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU, potentially leading to a denial of service.
- CVE-2019-9514 "Reset Flood": The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
- CVE-2019-9515 "Settings Flood": The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
- CVE-2019-9516 "0-Length Headers Leak": The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory, potentially leading to a denial of service.
- CVE-2019-9517 "Internal Data Buffering": The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
- CVE-2019-9518 "Empty Frames Flood": The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU, potentially leading to a denial of service. (Discovered by Piotr Sikora of Google)

Joe Cooper reports:
I've rolled out Webmin version 1.930 and Usermin version 1.780 for all repositories. This release includes several security fixes, including one potentially serious one caused by malicious code inserted into Webmin and Usermin at some point on our build infrastructure. We're still investigating how and when, but the exploitable code has never existed in our github repositories, so we've rebuilt from git source on new infrastructure (and checked to be sure the result does not contain the malicious code).
I don't have a changelog for these releases yet, but I wanted to announce them immediately due to the severity of this issue. To exploit the malicious code, your Webmin installation must have Webmin -> Webmin Configuration -> Authentication -> Password expiry policy set to Prompt users with expired passwords to enter a new one. This option is not set by default, but if it is set, it allows remote code execution.
This release addresses CVE-2019-15107, which was disclosed earlier today. It also addresses a handful of XSS issues that we were notified about, and a bounty was awarded to the researcher (a different one) who found them.
The Gitea Team reports:
This release contains two security fixes, so we highly recommend updating.
nvd.nist.gov reports
X.Org xdm 1.1.10, 1.1.11, and possibly other versions, when performing authentication using certain implementations of the crypt API function that can return NULL, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by attempting to log into an account whose password field contains invalid characters, as demonstrated using the crypt function from glibc 2.17 and later with (1) the "!" character in the salt portion of a password field or (2) a password that has been encrypted using DES or MD5 in FIPS-140 mode.
The Git community reports:
A carefully constructed commit object with a very large number of parents may lead to potential out-of-bounds writes or potential denial of service.

nghttp2 GitHub releases:
This release fixes CVE-2019-9511 "Data Dribble" and CVE-2019-9513 "Resource Loop" vulnerability in nghttpx and nghttpd. Specially crafted HTTP/2 frames cause Denial of Service by consuming CPU time. Check out https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for details. For nghttpx, additionally limiting inbound traffic by --read-rate and --read-burst options is quite effective against this kind of attack.
CVE-2019-9511 "Data Dribble": The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9513 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

NGINX Team reports:
Several security issues were identified in nginx HTTP/2 implementation which might cause excessive memory consumption and CPU usage (CVE-2019-9511, CVE-2019-9513, CVE-2019-9516). The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the http2 option of the listen directive is used in a configuration file.
Nokogiri GitHub release:
A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess by Ruby's Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.
This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.

The KDE Community has released a security announcement:
The syntax Key[$e]=$(shell command) in *.desktop files, .directory files, and configuration files (typically found in ~/.config) was an intentional feature of KConfig, to allow flexible configuration. This could however be abused by malicious people to make the users install such files and get code executed even without intentional action by the user.
Jesse Smith (upstream author of the doas program) reported:
Previous versions of "doas" transferred most environment variables, such as USER, HOME, and PATH from the original user to the target user. Passing these variables could cause files in the wrong path or home directory to be read (or written to), which resulted in potential security problems.
Many thanks to Sander Bos for reporting this issue and explaining how it can be exploited.
Jon Siwek of Corelight reports:
This is a security patch release to address potential Denial of Service vulnerabilities:
- Null pointer dereference in the RPC analysis code. RPC analyzers (e.g. MOUNT or NFS) are not enabled in the default configuration.
- Signed integer overflow in BinPAC-generated parser code. The result of this is Undefined Behavior with respect to the array bounds checking conditions that BinPAC generates, so it's unpredictable what an optimizing compiler may actually do under the assumption that signed integer overlows should never happen. The specific symptom which lead to finding this issue was with the PE analyzer causing out-of-memory crashes due to large allocations that were otherwise prevented when the array bounds checking logic was changed to prevent any possible signed integer overlow.
The PostgreSQL project reports:
Versions Affected: 9.4 - 11
Given a suitable `SECURITY DEFINER` function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires `EXECUTE` permission on the function, which must itself contain a function call having inexact argument type match. For example, `length('foo'::varchar)` and `length('foo')` are inexact, while `length('foo'::text)` is exact. As part of exploiting this vulnerability, the attacker uses `CREATE DOMAIN` to create a type in a `pg_temp` schema. The attack pattern and fix are similar to that for CVE-2007-2138.
Writing `SECURITY DEFINER` functions continues to require following the considerations noted in the documentation:
https://www.postgresql.org/docs/devel/sql-createfunction.html#SQL-CREATEFUNCTION-SECURITY
Versions Affected: 11
In a database containing hypothetical, user-defined hash equality operators, an attacker could read arbitrary bytes of server memory. For an attack to become possible, a superuser would need to create unusual operators. It is possible for operators not purpose-crafted for attack to have the properties that enable an attack, but we are not aware of specific examples.
Django release notes:
CVE-2019-14232: Denial-of-service possibility in django.utils.text.Truncator
If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable
The regular expressions used by Truncator have been simplified in order to avoid potential backtracking issues. As a consequence, trailing punctuation may now at times be included in the truncated output.
CVE-2019-14233: Denial-of-service possibility in strip_tags()
Due to the behavior of the underlying HTMLParser, django.utils.html.strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable.
strip_tags() now avoids recursive calls to HTMLParser when progress removing tags, but necessarily incomplete HTML entities, stops being made.
Remember that absolutely NO guarantee is provided about the results of strip_tags() being HTML safe. So NEVER mark safe the result of a strip_tags() call without escaping it first, for example with django.utils.html.escape().
CVE-2019-14234: SQL injection possibility in key and index lookups for JSONField/HStoreField
Key and index lookups for JSONField and key lookups for HStoreField were subject to SQL injection, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to QuerySet.filter().
CVE-2019-14235: Potential memory exhaustion in django.utils.encoding.uri_to_iri()
If passed certain inputs, django.utils.encoding.uri_to_iri() could lead to significant memory usage due to excessive recursion when re-percent-encoding invalid UTF-8 octet sequences.
uri_to_iri() now avoids recursion when re-percent-encoding invalid UTF-8 octet sequences.
The Gitea Team reports:
This version of Gitea contains security fixes that could not be backported to 1.8. For this reason, we strongly recommend updating.
If a process attempts to transmit rights over a UNIX-domain socket and an error causes the attempt to fail, references acquired on the rights are not released and are leaked. This bug can be used to cause the reference counter to wrap around and free the corresponding file structure.
A local user can exploit the bug to gain root privileges or escape from a jail.
The pci_xhci_device_doorbell() function does not validate the 'epid' and 'streamid' provided by the guest, leading to an out-of-bounds read.
A misbehaving bhyve guest could crash the system or access memory that it should not be able to.
System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file.
A local user can use this flaw to obtain access to files, directories, sockets etc. opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.
Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes.
A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions 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.
The code which handles a close(2) of a descriptor created by posix_openpt(2) fails to undo the configuration which causes SIGIO to be raised. This bug can lead to a write-after-free of kernel memory.
The bug permits malicious code to trigger a write-after-free, which may be used to gain root privileges or escape a jail.
Insufficient validation of environment variables in the telnet client supplied in FreeBSD can lead to stack-based buffer overflows. A stack- based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers.
This issue only affects the telnet client. Inbound telnet sessions to telnetd(8) are not affected by this issue.
These buffer overflows may be triggered when connecting to a malicious server, or by an active attacker in the network path between the client and server. Specially crafted TELNET command sequences may cause the execution of arbitrary code with the privileges of the user invoking telnet(1).
To implement one particular ioctl, the Linux emulation code used a special interface present in the cd(4) driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd(4) device to arbitrarily overwrite kernel memory when some media is present in the device.
A user in the operator group can make use of this interface to gain root privileges on a system with a cd(4) device when some media is present in the device.
A bug causes up to three bytes of kernel stack memory to be written to disk as uninitialized directory entry padding. This data can be viewed by any user with read access to the directory. Additionally, a malicious user with write access to a directory can cause up to 254 bytes of kernel stack memory to be exposed.
Some amount of the kernel stack is disclosed and written out to the filesystem.
With certain inputs, iconv may write beyond the end of the output buffer.
Depending on the way in which iconv is used, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. iconv is a libc library function and the nature of possible attacks will depend on the way in which iconv is used by applications or daemons.
While processing acknowledgements, the RACK code uses several linked lists to maintain state entries. A malicious attacker can cause the lists to grow unbounded. This can cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service.
An attacker with the ability to send specially crafted TCP traffic to a victim system can degrade network performance and/or consume excessive CPU by exploiting the inefficiency of traversing the potentially very large RACK linked lists with relatively small bandwidth cost.
On some Intel processors utilizing speculative execution a local process may be able to infer stale information from microarchitectural buffers to obtain a memory disclosure.
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).
States in pf(4) let ICMP and ICMP6 packets pass if they have a packet in their payload matching an existing condition. pf(4) does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet.
A maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.
A bug in the pf(4) IPv6 fragment reassembly logic incorrectly uses the last extension header offset from the last received packet instead of from the first packet.
Malicious IPv6 packets with different IPv6 extensions could cause a kernel panic or potentially a filtering rule bypass.

Matrix developers report:
The matrix team releases Synapse 1.2.1 as a critical security update. It contains patches relating to redactions and event federation:
- Prevent an attack where a federated server could send redactions for arbitrary events in v1 and v2 rooms.
- Prevent a denial-of-service attack where cycles of redaction events would make Synapse spin infinitely.
- Prevent an attack where users could be joined or parted from public rooms without their consent.
- Fix a vulnerability where a federated server could spoof read-receipts from users on other servers.
- It was possible for a room moderator to send a redaction for an m.room.create event, which would downgrade the room to version 1.
Exim team report:
A local or remote attacker can execute programs with root privileges - if you've an unusual configuration.
If your configuration uses the ${sort } expansion for items that can be controlled by an attacker (e.g. $local_part, $domain). The default config, as shipped by the Exim developers, does not contain ${sort }.
The vulnerability is exploitable either remotely or locally and could be used to execute other programs with root privilege. The ${sort } expansion re-evaluates its items.
Exim 4.92.1 is not vulnerable.
Oracle reports:
This Critical Patch Update contains 45 new security fixes for Oracle MySQL. 4 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.
Drupal Security Team reports:
In Drupal 8.7.4, when the experimental Workspaces module is enabled, an access bypass condition is created.
This can be mitigated by disabling the Workspaces module. It does not affect any release other than Drupal 8.7.4.
Simon Tatham reports:
Vulnerabilities fixed in this release include:
- A malicious SSH-1 server could trigger a buffer overrun by sending extremely short RSA keys, or certain bad packet length fields. Either of these could happen before host key verification, so even if you trust the server you *intended* to connect to, you would still be at risk.
(However, the SSH-1 protocol is obsolete, and recent versions of PuTTY do not try it by default, so you are only at risk if you work with old servers and have explicitly configured SSH-1.)- If a malicious process found a way to impersonate Pageant, then it could cause an integer overflow in any of the SSH client tools (PuTTY, Plink, PSCP, PSFTP) which accessed the malicious Pageant.
Other security-related bug fixes include:
- The 'trust sigil' system introduced in PuTTY 0.71 to protect against server spoofing attacks had multiple bugs. Trust sigils were not turned off after login in the SSH-1 and Rlogin protocols, and not turned back on if you used the Restart Session command. Both are now fixed.

The issue is due to the fact that the Authoritative Server will exit when it runs into a parsing error while looking up the NS/A/AAAA records it is about to use for an outgoing notify.
CVE-2019-10163: An issue has been found in PowerDNS Authoritative Server allowing a remote, authorized master server to cause a high CPU load or even prevent any further updates to any slave zone by sending a large number of NOTIFY messages. Note that only servers configured as slaves are affected by this issue.

The PostgreSQL project reports:
An authenticated user could create a stack-based buffer overflow by changing their own password to a purpose-crafted value. In addition to the ability to crash the PostgreSQL server, this could be further exploited to execute arbitrary code as the PostgreSQL operating system account.
Additionally, a rogue server could send a specifically crafted message during the SCRAM authentication process and cause a libpq-enabled client to either crash or execute arbitrary code as the client's operating system account.
This issue is fixed by upgrading and restarting your PostgreSQL server as well as your libpq installations. All users running PostgreSQL 10, 11, and 12 beta are encouraged to upgrade as soon as possible.

[961413] High CVE-2019-5842: Use-after-free in Blink. Reported by BUGFENSE Anonymous Bug Bounties https://bugfense.io on 2019-05-09
The phpMyAdmin development team reports:
Summary
CSRF vulnerability in login form
Description
A vulnerability was found that allows an attacker to trigger a CSRF attack against a phpMyAdmin user. The attacker can trick the user, for instance through a broken
<img>tag pointing at the victim's phpMyAdmin database, and the attacker can potentially deliver a payload (such as a specific INSERT or DELETE statement) through the victim.Severity
We consider this vulnerability to be severe.
Mitigation factor
Only the 'cookie' auth_type is affected; users can temporary use phpMyAdmin's http authentication as a workaround.

CVE-2019-11831: By-passing protection of Phar Stream Wrapper Interceptor.
In order to intercept file invocations like file_exists or stat on compromised Phar archives the base name has to be determined and checked before allowing to be handled by PHP Phar stream handling. The current implementation is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file.

We received a report of a possible remote exploit. Currently there is no evidence of an active use of this exploit.
A patch exists already, is being tested, and backported to all versions we released since (and including) 4.87.
The severity depends on your configuration. It depends on how close to the standard configuration your Exim runtime configuration is. The closer the better.
Exim 4.92 is not vulnerable.

Buildbot accepted user-submitted authorization token from OAuth and used it to authenticate user.
The vulnerability can lead to malicious attackers to authenticate as legitimate users of a Buildbot instance without knowledge of the victim's login credentials on certain scenarios.
If an attacker has an application authorized to access data of another user at the same Identity Provider as the used by the Buildbot instance, then he can acquire a token to access the data of that user, supply the token to the Buildbot instance and successfully login as the victim.
Jon Siwek of Corelight reports:
The following Denial of Service vulnerabilities are addressed:
- Integer type mismatches in BinPAC-generated parser code and Bro analyzer code may allow for crafted packet data to cause unintentional code paths in the analysis logic to be taken due to unsafe integer conversions causing the parser and analysis logic to each expect different fields to have been parsed. One such example, reported by Maksim Shudrak, causes the Kerberos analyzer to dereference a null pointer. CVE-2019-12175 was assigned for this issue.
- The Kerberos parser allows for several fields to be left uninitialized, but they were not marked with an &optional attribute and several usages lacked existence checks. Crafted packet data could potentially cause an attempt to access such uninitialized fields, generate a runtime error/exception, and leak memory. Existence checks and &optional attributes have been added to the relevent Kerberos fields.
- BinPAC-generated protocol parsers commonly contain fields whose length is derived from other packet input, and for those that allow for incremental parsing, BinPAC did not impose a limit on how large such a field could grow, allowing for remotely-controlled packet data to cause growth of BinPAC's flowbuffer bounded only by the numeric limit of an unsigned 64-bit integer, leading to memory exhaustion. There is now a generalized limit for how large flowbuffers are allowed to grow, tunable by setting "BinPAC::flowbuffer_capacity_max".

MITRE reports:
An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
Mitre reports:
An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \r results in an integer underflow.
curl security problems:
CVE-2019-5435: Integer overflows in curl_url_set()
libcurl contains two integer overflows in the curl_url_set() function that if triggered, can lead to a too small buffer allocation and a subsequent heap buffer overflow.
The flaws only exist on 32 bit architectures and require excessive string input lengths.
CVE-2019-5436: TFTP receive buffer overflow
libcurl contains a heap buffer overflow in the function (tftp_receive_packet()) that recevives data from a TFTP server. It calls recvfrom() with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is entirely controlled by the server.
The flaw exists if the user selects to use a "blksize" of 504 or smaller (default is 512). The smaller size that is used, the larger the possible overflow becomes.
Users chosing a smaller size than default should be rare as the primary use case for changing the size is to make it larger.
It is rare for users to use TFTP across the Internet. It is most commonly used within local networks.
MITRE reports:
OCaml before 4.03.0 does not properly handle sign extensions, which allows remote attackers to conduct buffer overflow attacks or obtain sensitive information as demonstrated by a long string to the String.copy function.

Sean McArthur reports:
The Rust Programming Language Standard Library 1.34.x before 1.34.2 contains a stabilized method which, if overridden, can violate Rust's safety guarantees and cause memory unsafety. If the Error::type_id method is overridden then any type can be safely cast to any other type, causing memory safety vulnerabilities in safe code (e.g., out-of-bounds write or read). Code that does not manually implement Error::type_id is unaffected.

The PostgreSQL project reports:
PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process. Prior to this release, a user able to execute SQL queries with permissions to read a given column could craft a leaky operator that could read whatever data had been sampled from that column. If this happened to include values from rows that the user is forbidden to see by a row security policy, the user could effectively bypass the policy. This is fixed by only allowing a non-leakproof operator to use this data if there are no relevant row security policies for the table.
The PostgreSQL project reports:
Prior to this release, a user running PostgreSQL 11 can read arbitrary bytes of server memory by executing a purpose-crafted INSERT statement to a partitioned table.

See https://w1.fi/security/2019-4/eap-pwd-missing-commit-validation.txt for a detailed description of the bug.
All wpa_supplicant and hostapd versions with EAP-pwd support.
When hostapd is used to operate an access point with SAE (Simultaneous Authentication of Equals; also known as WPA3-Personal), an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm message. This was caused by missing state validation steps when processing the SAE confirm message in hostapd/AP mode.
See https://w1.fi/security/2019-3/sae-confirm-missing-state-validation.txt for a detailed description of the bug.
All hostapd versions with SAE support (CONFIG_SAE=y in the build configuration and SAE being enabled in the runtime configuration).
Potential side channel attacks in the SAE implementations used by both hostapd and wpa_supplicant (see CVE-2019-9494 and VU#871675). EAP-pwd uses a similar design for deriving PWE from the password and while a specific attack against EAP-pwd is not yet known to be tested, there is no reason to believe that the EAP-pwd implementation would be immune against the type of cache attack that was identified for the SAE implementation. Since the EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not support MODP groups, the timing attack described against SAE is not applicable for the EAP-pwd implementation.
See https://w1.fi/security/2019-2/eap-pwd-side-channel-attack.txt for a detailed description of the bug.
All wpa_supplicant and hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled in the runtime configuration).
Side channel attacks in the SAE implementations used by both hostapd (AP) and wpa_supplicant (infrastructure BSS station/mesh station). SAE (Simultaneous Authentication of Equals) is also known as WPA3-Personal. The discovered side channel attacks may be able to leak information about the used password based on observable timing differences and cache access patterns. This might result in full password recovery when combined with an offline dictionary attack and if the password is not strong enough to protect against dictionary attacks.

Jupyter blog:
Login pages tend to take a parameter for redirecting back to a page after successful login, e.g. /login?next=/notebooks/mynotebook.ipynb, so that you aren't disrupted too much if you try to visit a page, but have to authenticate first. An Open Redirect Vulnerability is when a malicious person crafts a link pointing to the login page of a trusted site, but setting the "redirect after successful login" parameter to send the user to their own site, instead of a page on the authenticated site (the notebook or JupyterHub server), e.g. /login?next=http://badwebsite.biz. This doesn't necessarily compromise anything immediately, but it enables phishing if users don't notice that the domain has changed, e.g. by showing a fake "re-enter your password" page. Servers generally have to validate the redirect URL to avoid this. Both JupyterHub and Notebook already do this, but the validation didn't take into account all possible ways to redirect to other sites, so some malicious URLs could still be crafted to redirect away from the server (the above example does not work in any recent version of either package).

Vulnerability Details: When reading FTS or POP3-UIDL header from dovecot index, the input buffer size is not bound, and data is copied to target structure causing stack overflow. Risk: This can be used for local root privilege escalation or executing arbitrary code in dovecot process context. This requires ability to directly modify dovecot indexes. Steps to reproduce: Produce dovecot.index.log entry that creates an FTS header which has more than 12 bytes of data. Trigger dovecot indexer-worker or run doveadm index. Dovecot will crash. Mitigations: Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, read-only GOT tables and other techniques that make exploiting this bug much harder.

Project Runner Token Exposed Through Issues Quick Actions
The freedesktop and x.org project reports:
It was discovered that libXdmcp before 1.1.3 used weak entropy to generate session keys on platforms without arc4random_buf() but with getentropy(). On a multi-user system using xdmcp, a local attacker could potentially use information available from the process list to brute force the key, allowing them to hijack other users' sessions.
Please note, that since FreeBSD provides arc4random_buf(), it is unknown if FreeBSD is affected by this vulnerability

PowerDNS developers report:
An issue has been found in PowerDNS Authoritative Server when the HTTP remote backend is used in RESTful mode (without post=1 set), allowing a remote user to cause the HTTP backend to connect to an attacker-specified host instead of the configured one, via a crafted DNS query. This can be used to cause a denial of service by preventing the remote backend from getting a response, content spoofing if the attacker can time its own query so that subsequent queries will use an attacker-controlled HTTP server instead of the configured one, and possibly information disclosure if the Authoritative Server has access to internal servers.

The OpenSSL project reports:
Low: ChaCha20-Poly1305 with long nonces (CVE-2019-1543)
ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored.
Network Time Foundation reports:
A crafted malicious authenticated mode 6 (ntpq) packet from a permitted network address can trigger a NULL pointer dereference, crashing ntpd.
Note that for this attack to work, the sending system must be on an address that the target's ntpd accepts mode 6 packets from, and must use a private key that is specifically listed as being used for mode 6 authorization.
Impact: The ntpd daemon can crash due to the NULL pointer dereference, causing a denial of service.
Mitigation:
- Use restrict noquery to limit addresses that can send mode 6 queries.
- Limit access to the private controlkey in ntp.keys.
- Upgrade to 4.2.8p13, or later.

Node.js reports:
Updates are now available for all active Node.js release lines. In addition to fixes for security flaws in Node.js, they also include upgrades of Node.js 6 and 8 to OpenSSL 1.0.2r which contains a fix for a moderate severity security vulnerability.
For these releases, we have decided to withhold the fix for the Misinterpretation of Input (CWE-115) flaw mentioned in the original announcement. This flaw is very low severity and we are not satisfied that we had a complete and stable fix ready for release. We will be seeking to address this flaw via alternate mechanisms in the near future. In addition, we have introduced an additional CVE for a change in Node.js 6 that we have decided to classify as a Denial of Service (CWE-400) flaw.
We recommend that all Node.js users upgrade to a version listed below as soon as possible.
OpenSSL: 0-byte record padding oracle (CVE-2019-1559)
OpenSSL 1.0.2r contains a fix for CVE-2019-1559 and is included in the releases for Node.js versions 6 and 8 only. Node.js 10 and 11 are not impacted by this vulnerability as they use newer versions of OpenSSL which do not contain the flaw.
Under certain circumstances, a TLS server can be forced to respond differently to a client if a zero-byte record is received with an invalid padding compared to a zero-byte record with an invalid MAC. This can be used as the basis of a padding oracle attack to decrypt data.
Only TLS connections using certain ciphersuites executing under certain conditions are exploitable. We are currently unable to determine whether the use of OpenSSL in Node.js exposes this vulnerability. We are taking a cautionary approach and recommend the same for users. For more information, see the advisory and a detailed write-up by the reporters of the vulnerability.

Some field types do not properly sanitize data from non-form sources. This can lead to arbitrary PHP code execution in some cases..
The OpenSSL project reports:
0-byte record padding oracle (CVE-2019-1559) (Moderate)
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data.

Adobe reports:
- This update resolves an out-of-bounds vulnerability that could lead to information disclosure (CVE-2019-7090).
NVD reports:
In OpenJPEG 2.3.0, there is an integer overflow vulnerability in the opj_t1_encode_cblks function (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
FreeBSD 12.0 attempts to handle the case where the receiving process does not provide a sufficiently large buffer for an incoming control message containing rights. In particular, to avoid leaking the corresponding descriptors into the receiving process' descriptor table, the kernel handles the truncation case by closing descriptors referenced by the discarded message.
The code which performs this operation failed to release a reference obtained on the file corresponding to a received right. This bug can be used to cause the reference counter to wrap around and free the file structure.
A local user can exploit the bug to gain root privileges or escape from a jail.
The callee-save registers are used by kernel and for some of them (%r8, %r10, and for non-PTI configurations, %r9) the content is not sanitized before return from syscalls, potentially leaking sensitive information.
Typically an address of some kernel data structure used in the syscall implementation, is exposed.

curl security problems:
CVE-2018-16890: NTLM type-2 out-of-bounds buffer read
libcurl contains a heap buffer out-of-bounds read flaw.
The function handling incoming NTLM type-2 messages (lib/vauth/ntlm.c:ntlm_decode_type2_target) does not validate incoming data correctly and is subject to an integer overflow vulnerability.
Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2019-3822: NTLMv2 type-3 header stack buffer overflow
libcurl contains a stack based buffer overflow vulnerability.
The function creating an outgoing NTLM type-3 header (lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening.
This output data can grow larger than the local buffer if very large "nt response" data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server.
Such a "large value" needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-3823: SMTP end-of-response out-of-bounds read
libcurl contains a heap out-of-bounds read in the code handling the end-of-response for SMTP.
If the buffer passed to smtp_endofresp() isn't NUL terminated and contains no character ending the parsed number, and len is set to 5, then the strtol() call reads beyond the allocated buffer. The read contents will not be returned to the caller.
Gitlab reports:
Leak of Confidential Issue and Merge Request Titles
Persistent XSS in User Status
Aki Tuomi (Open-Xchange Oy) reports:
Normally Dovecot is configured to authenticate imap/pop3/managesieve/submission clients using regular username/password combination. Some installations have also required clients to present a trusted SSL certificate on top of that. It's also possible to configure Dovecot to take the username from the certificate instead of from the user provided authentication. It's also possible to avoid having a password at all, only trusting the SSL certificate. If the provided trusted SSL certificate is missing the username field, Dovecot should be failing the authentication. However, the earlier versions will take the username from the user provided authentication fields (e.g. LOGIN command). If there is no additional password verification, this allows the attacker to login as anyone else in the system. This affects only installations using: auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes Attacker must also have access to a valid trusted certificate without the ssl_cert_username_field in it. The default is commonName, which almost certainly exists in all certificates. This could happen for example if ssl_cert_username_field is a field that normally doesn't exist, and attacker has access to a web server's certificate (and key), which is signed with the same CA. Attack can be migitated by having the certificates with proper Extended Key Usage, such as 'TLS Web Server' and 'TLS Web Server Client'. Also, ssl_cert_username_field setting was ignored with external SMTP AUTH, because none of the MTAs (Postfix, Exim) currently send the cert_username field. This may have allowed users with trusted certificate to specify any username in the authentication. This does not apply to Dovecot Submission service.

The phpMyAdmin development team reports:
Summary
Arbitrary file read vulnerability
Description
When
AllowArbitraryServerconfiguration set totrue, with the use of a rogue MySQL server, an attacker can read any file on the server that the web server's user can access.phpMyadmin attempts to block the use of
LOAD DATA INFILE, but due to a bug in PHP, this check is not honored. Additionally, when using the 'mysql' extension, mysql.allow_local_infile is enabled by default. Both of these conditions allow the attack to occur.Severity
We consider this vulnerability to be critical.
Mitigation factor
This attack can be mitigated by setting the `AllowArbitraryServer` configuration directive to false (which is the default value).
Affected Versions
phpMyAdmin versions from at least 4.0 through 4.8.4 are affected
Summary

A vulnerability has been found that would allow attackers to direct a peer to jump to and execute from an address indicated by the attacker. This issue has been present since v4.2.0. Older releases are not affected. NOTE: The attacker needs to know in advance valid addresses in the peer's memory to jump to, so measures like ASLR are effective mitigations. NOTE: this attack can only take place after authentication, so peers behind CURVE/GSSAPI are not vulnerable to unauthenticated attackers.

MITRE Corporation reports:
GLPI before before version 9.4.6 has a vulnerability involving a default encryption key. GLPIKEY is public and is used on every instance. This means anyone can decrypt sensitive data stored using this key. It is possible to change the key before installing GLPI. But on existing instances, data must be reencrypted with the new key. Problem is we can not know which columns or rows in the database are using that; espcially from plugins. Changing the key without updating data would lend in bad password sent from glpi; but storing them again from the UI will work.
MITRE Corporation reports:
In GLPI before 9.5.3, ajax/getDropdownValue.php has an Insecure Direct Object Reference (IDOR) vulnerability that allows an attacker to read data from any itemType (e.g., Ticket, Users, etc.).
MITRE Corporation reports:
In GLPI before 9.5.3, ajax/comments.php has an Insecure Direct Object Reference (IDOR) vulnerability that allows an attacker to read data from any database table (e.g., glpi_tickets, glpi_users, etc.).
MITRE Corporation reports:
In GLPI before version 9.5.3, any authenticated user has read-only permissions to the planning of every other user, even admin ones. This issue is fixed in version 9.5.3. As a workaround, one can remove the caldav.php file to block access to CalDAV server.
MITRE Corporation reports:
In GLPI before version 9.5.2, there is a SQL Injection in the API's search function. Not only is it possible to break the SQL syntax, but it is also possible to utilise a UNION SELECT query to reflect sensitive information such as the current database version, or database user. The most likely scenario for this vulnerability is with someone who has an API account to the system. The issue is patched in version 9.5.2. A proof-of-concept with technical details is available in the linked advisory.
MITRE Corporation reports:
In GLPI before version 9.5.2, there is a leakage of user information through the public FAQ. The issue was introduced in version 9.5.0 and patched in 9.5.2. As a workaround, disable public access to the FAQ.
MITRE Corporation reports:
In GLPI before version 9.5.2, the `install/install.php` endpoint insecurely stores user input into the database as `url_base` and `url_base_api`. These settings are referenced throughout the application and allow for vulnerabilities like Cross-Site Scripting and Insecure Redirection Since authentication is not required to perform these changes,anyone could point these fields at malicious websites or form input in a way to trigger XSS. Leveraging JavaScript it's possible to steal cookies, perform actions as the user, etc. The issue is patched in version 9.5.2.
MITRE Corporation reports:
In GLPI before version 9.5.2, when supplying a back tick in input that gets put into a SQL query,the application does not escape or sanitize allowing for SQL Injection to occur. Leveraging this vulnerability an attacker is able to exfiltrate sensitive information like passwords, reset tokens, personal details, and more. The issue is patched in version 9.5.2
MITRE Corporation reports:
In GLPI before version 9.5.2, the pluginimage.send.php endpoint allows a user to specify an image from a plugin. The parameters can be maliciously crafted to instead delete the .htaccess file for the files directory. Any user becomes able to read all the files and folders contained in /files/. Some of the sensitive information that is compromised are the user sessions, logs, and more. An attacker would be able to get the Administrators session token and use that to authenticate. The issue is patched in version 9.5.2.
MITRE Corporation reports:
In glpi before 9.5.1, there is a SQL injection for all usages of "Clone" feature. This has been fixed in 9.5.1.
MITRE Corporation reports:
In GLPI after 0.68.1 and before 9.4.6, multiple reflexive XSS occur in Dropdown endpoints due to an invalid Content-Type. This has been fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI before 9.4.6, an attacker can execute system commands by abusing the backup functionality. Theoretically, this vulnerability can be exploited by an attacker without a valid account by using a CSRF. Due to the difficulty of the exploitation, the attack is only conceivable by an account having Maintenance privileges and the right to add WIFI networks. This is fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI before version 9.4.6 there are multiple related stored XSS vulnerabilities. The package is vulnerable to Stored XSS in the comments of items in the Knowledge base. Adding a comment with content "alert(1)" reproduces the attack. This can be exploited by a user with administrator privileges in the User-Agent field. It can also be exploited by an outside party through the following steps: 1. Create a user with the surname `" onmouseover="alert(document.cookie)` and an empty first name. 2. With this user, create a ticket 3. As an administrator (or other privileged user) open the created ticket 4. On the "last update" field, put your mouse on the name of the user 5. The XSS fires This is fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI after version 0.83.3 and before version 9.4.6, the CSRF tokens are generated using an insecure algorithm. The implementation uses rand and uniqid and MD5 which does not provide secure values. This is fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI before version 9.4.6, there is a vulnerability that allows bypassing the open redirect protection based which is based on a regexp. This is fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI from version 9.1 and before version 9.4.6, any API user with READ right on User itemtype will have access to full list of users when querying apirest.php/User. The response contains: - All api_tokens which can be used to do privileges escalations or read/update/delete data normally non accessible to the current user. - All personal_tokens can display another users planning. Exploiting this vulnerability requires the api to be enabled, a technician account. It can be mitigated by adding an application token. This is fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI before version 9.4.6, there is a SQL injection vulnerability for all helpdesk instances. Exploiting this vulnerability requires a technician account. This is fixed in version 9.4.6.
MITRE Corporation reports:
In GLPI before version 9.5.0, the encryption algorithm used is insecure. The security of the data encrypted relies on the password used, if a user sets a weak/predictable password, an attacker could decrypt data. This is fixed in version 9.5.0 by using a more secure encryption library. The library chosen is sodium.
MITRE Corporation reports:
GLPI through 9.4.3 is prone to account takeover by abusing the ajax/autocompletion.php autocompletion feature. The lack of correct validation leads to recovery of the token generated via the password reset functionality, and thus an authenticated attacker can set an arbitrary password for any user. This vulnerability can be exploited to take control of admin account. This vulnerability could be also abused to obtain other sensitive fields like API keys or password hashes.
The cURL project reports:
Trusting FTP PASV responses (CVE-2020-8284)
FTP wildcard stack overflow (CVE-2020-8285)

The OpenSSL project reports:
EDIPARTYNAME NULL pointer de-reference (High)
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack.

The Gitea Team reports for release 1.13.0:
- Add Allow-/Block-List for Migrate and Mirrors
- Prevent git operations for inactive users
- Disallow urlencoded new lines in git protocol paths if there is a port
- Mitigate Security vulnerability in the git hook feature
- Disable DSA ssh keys by default

Two bugs exist in rtsold(8)'s RDNSS and DNSSL option handling. First, rtsold(8) failed to perform sufficient bounds checking on the extent of the option. In particular, it does not verify that the option does not extend past the end of the received packet before processing its contents. The kernel currently ignores such malformed packets but still passes them to userspace programs.
Second, when processing a DNSSL option, rtsold(8) decodes domain name labels per an encoding specified in RFC 1035 in which the first octet of each label contains the label's length. rtsold(8) did not validate label lengths correctly and could overflow the destination buffer.
It is believed that these bugs could be exploited to gain remote code execution within the rtsold(8) daemon, which runs as root. Note that rtsold(8) only processes messages received from hosts attached to the same physical link as the interface(s) on which rtsold(8) is listening.
In FreeBSD 12.2 rtsold(8) runs in a Capsicum sandbox, limiting the scope of a compromised rtsold(8) process.
When an ICMPv6 error message is received, the FreeBSD ICMPv6 stack may extract information from the message to hand to upper-layer protocols. As a part of this operation, it may parse IPv6 header options from a packet embedded in the ICMPv6 message.
The handler for a routing option caches a pointer into the packet buffer holding the ICMPv6 message. However, when processing subsequent options the packet buffer may be freed, rendering the cached pointer invalid. The network stack may later dereference the pointer, potentially triggering a use-after-free.
A remote host may be able to trigger a read of freed kernel memory. This may trigger a kernel panic if the address had been unmapped.
The X.org project reports:
These issues can lead to privileges elevations for authorized clients on systems where the X server is running privileged.
Insufficient checks on the lengths of the XkbSetMap request can lead to out of bounds memory accesses in the X server.
Insufficient checks on input of the XkbSetDeviceInfo request can lead to a buffer overflow on the head in the X server.

The Go project reports:
A number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD) can panic when provided crafted large inputs. For the panic to happen, the divisor or modulo argument must be larger than 3168 bits (on 32-bit architectures) or 6336 bits (on 64-bit architectures). Multiple math/big.Rat methods are similarly affected.
The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code. This can be caused by a malicious gcc flags specified via a #cgo directive.

- CVE-2020-25592: Properly validate eauth credentials and tokens along with their ACLs. Prior to this change eauth was not properly validated when calling Salt ssh via the salt-api. Any value for 'eauth' or 'token' would allow a user to bypass authentication and make calls to Salt ssh.
The Apache Openofffice project reports:
CVE-2020-13958 Unrestricted actions leads to arbitrary code execution in crafted documents
Description
A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing hyperlinks pointing to an executable on the target users file system. These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol may be called from the document event handler and other hyperlinks require a control-click.
Severity: Low
There are no known exploits of this vulnerability.
A proof-of-concept demonstration exists.Thanks to the reporter for discovering this issue.
Acknowledgments
The Apache OpenOffice Security Team would like to thank Imre Rad for discovering and reporting this attack vector.

The Asterisk project reports:
If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur.
The Asterisk project reports:
Upon receiving a new SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the creation of the dialog object, and its next use by the thread that created it. Depending upon some off nominal circumstances, and timing it was possible for another thread to free said dialog in this gap. Asterisk could then crash when the dialog object, or any of its dependent objects were de-referenced, or accessed next by the initial creation thread.

KDE Project Security Advisory
Title KDE Connect: packet manipulation can be exploited in a Denial of Service attack Risk Rating Important CVE CVE-2020-26164 Versions kdeconnect <= 20.08.1 Author Albert Vaca Cintora <albertvaka@gmail.com> Date 2 October 2020 Overview
An attacker on your local network could send maliciously crafted packets to other hosts running kdeconnect on the network, causing them to use large amounts of CPU, memory or network connections, which could be used in a Denial of Service attack within the network.
Impact
Computers that run kdeconnect are susceptible to DoS attacks from the local network.
Workaround
We advise you to stop KDE Connect when on untrusted networks like those on airports or conferences.
Since kdeconnect is dbus activated it is relatively hard to make sure it stays stopped so the brute force approach is to uninstall the kdeconnect package from your system and then run
kquitapp5 kdeconnectdJust install the package again once you're back in a trusted network.
Solution
KDE Connect 20.08.2 patches several code paths that could result in a DoS.
You can apply these patches on top of 20.08.1:

Affected Synapse versions assume that all events have an "origin" field set. If an event without the "origin" field is sent into a federated room, servers not already joined to the room will be unable to do so due to failing to fetch the malformed event.
An attacker could cause a denial of service by deliberately sending a malformed event into a room, thus preventing new servers (and thus their users) from joining the room.

Node.js reports:
Updates are now available for v10,x, v12.x and v14.x Node.js release lines for the following issues.
HTTP Request Smuggling due to CR-to-Hyphen conversion (High) (CVE-2020-8201)
Affected Node.js versions converted carriage returns in HTTP request headers to a hyphen before parsing. This can lead to HTTP Request Smuggling as it is a non-standard interpretation of the header.
Impacts:
- All versions of the 14.x and 12.x releases line
Denial of Service by resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests (Critical) (CVE-2020-8251)
Node.js is vulnerable to HTTP denial of service (DOS) attacks based on delayed requests submission which can make the server unable to accept new connections. The fix a new http.Server option called requestTimeout with a default value of 0 which means it is disabled by default. This should be set when Node.js is used as an edge server, for more details refer to the documentation.
Impacts:
- All versions of the 14.x release line
fs.realpath.native on may cause buffer overflow (Medium) (CVE-2020-8252)
libuv's realpath implementation incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes.
Impacts:
- All versions of the 10.x release line
- All versions of the 12.x release line
- All versions of the 14.x release line before 14.9.0
A ftpd(8) bug in the implementation of the file system sandbox, combined with capabilities available to an authenticated FTP user, can be used to escape the file system restriction configured in ftpchroot(5). Moreover, the bug allows a malicious client to gain root privileges.
A malicious FTP user can gain privileged access to an affected system.
A number of AMD virtualization instructions operate on host physical addresses, are not subject to nested page table translation, and guest use of these instructions was not trapped.
From kernel mode a malicious guest can write to arbitrary host memory (with some constraints), affording the guest full control of the host.
AMD and Intel CPUs support hardware virtualization using specialized data structures that control various aspects of guest operation. These are the Virtual Machine Control Structure (VMCS) on Intel CPUs, and the Virtual Machine Control Block (VMCB) on AMD CPUs. Insufficient access controls allow root users, including those running in a jail, to change these data structures.
An attacker with host root access (including to a jailed bhyve instance) can use this vulnerability to achieve kernel code execution.
A programming error in the ure(4) device driver caused some Realtek USB Ethernet interfaces to incorrectly report packets with more than 2048 bytes in a single USB transfer as having a length of only 2048 bytes.
An adversary can exploit this to cause the driver to misinterpret part of the payload of a large packet as a separate packet, and thereby inject packets across security boundaries such as VLANs.
An attacker that can send large frames (larger than 2048 bytes in size) to be received by the host (be it VLAN, or non-VLAN tagged packet), can inject arbitrary packets to be received and processed by the host. This includes spoofing packets from other hosts, or injecting packets to other VLANs than the host is on.

Version 5.9 contains security fix for L2TP clients and servers. Insufficient validation of incoming L2TP control packet specially crafted by unauthenticated user might lead to unexpected termination of the process. The problem affects mpd versions since 4.0 that brought in initial support for L2TP. Installations not using L2TP clients nor L2TP server configuration were not affected.
Manuel Pégourié-Gonnard reports:
An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) can recover the private keys used in RSA or static (finite-field) Diffie-Hellman operations.
Manuel Pégourié-Gonnard reports:
When decrypting/authenticating (D)TLS record in a connection using a CBC ciphersuite without the Encrypt-then-Mac extension RFC 7366, Mbed TLS used dummy rounds of the compression function associated with the hash used for HMAC in order to hide the length of the padding to remote attackers, as recommended in the original Lucky Thirteen paper.
A local attacker who is able to observe the state of the cache could monitor the presence of mbedtls_md_process() in the cache in order to determine when the actual computation ends and when the dummy rounds start. This is a reliable target as it's always called at least once, in response to a previous attack. The attacker can then continue with one of many well-documented Lucky 13 variants.
The GnuTLS project reports:
It was found by oss-fuzz that the server sending a "no_renegotiation" alert in an unexpected timing, followed by an invalid second handshake can cause a TLS 1.3 client to crash via a null-pointer dereference. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.
Django Release notes:
CVE-2020-24583: Incorrect permissions on intermediate-level directories on Python 3.7+
On Python 3.7+, FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files and to intermediate-level collected static directories when using the collectstatic management command.
CVE-2020-24584: Permission escalation in intermediate-level directories of the file system cache on Python 3.7+
On Python 3.7+, the intermediate-level directories of the file system cache had the system's standard umask rather than 0o077 (no group or others permissions).
Importing an OpenPGP key having a preference list for AEAD algorithms will lead to an array overflow and thus often to a crash or other undefined behaviour.
Importing an arbitrary key can often easily be triggered by an attacker and thus triggering this bug. Exploiting the bug aside from crashes is not trivial but likely possible for a dedicated attacker. The major hurdle for an attacker is that only every second byte is under their control with every first byte having a fixed value of 0x04.
When parsing option 119 data, dhclient(8) computes the uncompressed domain list length so that it can allocate an appropriately sized buffer to store the uncompressed list. The code to compute the length failed to handle certain malformed input, resulting in a heap overflow when the uncompressed list is copied into in inadequately sized buffer.
The heap overflow could in principle be exploited to achieve remote code execution. The affected process runs with reduced privileges in a Capsicum sandbox, limiting the immediate impact of an exploit. However, it is possible the bug could be combined with other vulnerabilities to escape the sandbox.
Due to improper handling in the kernel, a use-after-free bug can be triggered by sending large user messages from multiple threads on the same socket.
Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.
Due to improper mbuf handling in the kernel, a use-after-free bug might be triggered by sending IPv6 Hop-by-Hop options over the loopback interface.
Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

When a Handler does not explicitly set the Content-Type header, both CGI implementations default to “text/html”. If an attacker can make a server generate content under their control (e.g. a JSON containing user data or an uploaded image file) this might be mistakenly returned by the server as “text/html”. If a victim visits such a page they could get the attacker's code executed in the context of the server origin.

Overview
A maliciously crafted TAR archive containing symlink entries would install files anywhere in the user's home directory upon extraction.
Proof of concept
For testing, an example of malicious archive can be found at dirsymlink.tar
Impact
Users can unwillingly install files like a modified .bashrc, or a malicious script placed in ~/.config/autostart.
Workaround
Before extracting a downloaded archive using the Ark GUI, users should inspect it to make sure it doesn't contain symlink entries pointing outside the extraction folder.
The 'Extract' context menu from the Dolphin file manager shouldn't be used.
Solution
Ark 20.08.1 skips maliciously crafted symlinks when extracting TAR archives.
Alternatively, 8bf8c5ef07b0ac5e914d752681e470dea403a5bd can be applied to previous releases.

Miroslav Lichvar reports:
chrony-3.5.1 [...] fixes a security issue in writing of the pidfile.
When chronyd is configured to save the pidfile in a directory where the chrony user has write permissions (e.g. /var/run/chrony - the default since chrony-3.4), an attacker that compromised the chrony user account could create a symbolic link at the location of the pidfile to make chronyd starting with root privileges follow the symlink and write its process ID to a file for which the chrony user doesn't have write permissions, causing a denial of service, or data loss.
This issue was reported by Matthias Gerstner of SUSE.
Andrew Walker reports:
Issue 1:
Users are always granted permissions to cd into a directory. The check for whether execute is present on directories is a de-facto no-op. This cannot be mitigated without upgrading. Even setting an explicit "deny - execute" NFSv4 ACE will be bypassed.
Issue 2:
All ACEs for the owner_group (group@) and regular groups (group:<foo>) are granted the current user. This means that POSIX mode 770 is de-facto 777, and the below ACL is also de-facto 777 because the groupmember check for builtin_administrators returns True.
root@TESTBOX[~]# getfacl testfile # file: testfile # owner: root # group: wheel group:builtin_administrators:rwxpDdaARWcCos:-------:allow
Elastic reports:
A field disclosure flaw was found in Elasticsearch when running a scrolling search with Field Level Security. If a user runs the same query another more privileged user recently ran, the scrolling search can leak fields that should be hidden. This could result in an attacker gaining additional permissions against a restricted index.

curl security problems:
CVE-2020-8231: wrong connect-only connection
An application that performs multiple requests with libcurl's multi API and sets the CURLOPT_CONNECT_ONLY option, might in rare circumstances experience that when subsequently using the setup connect-only transfer, libcurl will pick and use the wrong connection - and instead pick another one the application has created since then.
CURLOPT_CONNECT_ONLY is the option to tell libcurl to not perform an actual transfer, only connect. When that operation is completed, libcurl remembers which connection it used for that transfer and "easy handle". It remembers the connection using a pointer to the internal connectdata struct in memory.
If more transfers are then done with the same multi handle before the connect-only connection is used, leading to the initial connect-only connection to get closed (for example due to idle time-out) while also new transfers (and connections) are setup, such a new connection might end up getting the exact same memory address as the now closed connect-only connection.
If after those operations, the application then wants to use the original transfer's connect-only setup to for example use curl_easy_send() to send raw data over that connection, libcurl could erroneously find an existing connection still being alive at the address it remembered since before even though this is now a new and different connection.
The application could then accidentally send data over that connection which wasn't at all intended for that recipient, entirely unknowingly.

When handling a 32-bit sendmsg(2) call, the compat32 subsystem copies the control message to be transmitted (if any) into kernel memory, and adjusts alignment of control message headers. The code which performs this work contained a time-of-check to time-of-use (TOCTOU) vulnerability which allows a malicious userspace program to modify control message headers after they were validated by the kernel.
The TOCTOU bug can be exploited by an unprivileged malicious userspace program to trigger privilege escalation.
A missing length validation code common to these three drivers means that a malicious USB device could write beyond the end of an allocated network packet buffer.
An attacker with physical access to a USB port and the ability to bring a network interface up may be able to use a specially crafted USB device to gain kernel or user-space code execution.
Typo3 Team reports:
In case an attacker manages to generate a valid cryptographic message authentication code (HMAC-SHA1) - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. This includes the possibility to fetch typo3conf/LocalConfiguration.php which again contains the encryptionKey as well as credentials of the database management system being used. In case a database server is directly accessible either via internet or in a shared hosting network, this allows to completely retrieve, manipulate or delete database contents. This includes creating an administration user account - which can be used to trigger remote code execution by injecting custom extensions.
It has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code (HMAC-SHA1) and can lead to various attack chains as described below.
The X.org project reports:
Allocation for pixmap data in AllocatePixmap() does not initialize the memory in xserver, it leads to leak uninitialize heap memory to clients. When the X server runs with elevated privileges.

KDE Project Security Advisory
Title: Ark: maliciously crafted archive can install files outside the extraction directory. Risk Rating: Important CVE: CVE-2020-16116 Versions: ark <= 20.04.3 Author: Elvis Angelaccio <elvis.angelaccio@kde.org> Date: 30 July 2020 Overview
A maliciously crafted archive with "../" in the file paths would install files anywhere in the user's home directory upon extraction.
Proof of concept
For testing, an example of malicious archive can be found at https://github.com/jwilk/traversal-archives/releases/download/0/relative2.zip
Impact
Users can unwillingly install files like a modified .bashrc, or a malicious script placed in ~/.config/autostart
Workaround
Users should not use the 'Extract' context menu from the Dolphin file manager. Before extracting a downloaded archive using the Ark GUI, users should inspect it to make sure it doesn't contain entries with "../" in the file path.
Solution
Ark 20.08.0 prevents loading of malicious archives and shows a warning message to the users.
Alternatively, https://invent.kde.org/utilities/ark/-/commit/0df592524fed305d6fbe74ddf8a196bc9ffdb92f can be applied to previous releases.
Credits
Thanks to Dominik Penner for finding and reporting this issue and thanks to Elvis Angelaccio and Albert Astals Cid for fixing it.

GitHub Advisory Database:
When a form page type is made available to Wagtail editors through the wagtail.contrib.forms app, and the page template is built using Django's standard form rendering helpers such as form.as_p (as directed in the documentation), any HTML tags used within a form field's help text will be rendered unescaped in the page. Allowing HTML within help text is an intentional design decision by Django; however, as a matter of policy Wagtail does not allow editors to insert arbitrary HTML by default, as this could potentially be used to carry out cross-site scripting attacks, including privilege escalation. This functionality should therefore not have been made available to editor-level users.
The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.
Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels, assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass invalid utf-8 strings to functions like pango_itemize.
The Apache Software Foundation reports:
An h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.

- CVE-2020-3350
- Fixed a vulnerability a malicious user could exploit to replace a scan target's directory with a symlink to another path to trick clamscan, clamdscan, or clamonacc into removing or moving a different file (such as a critical system file). The issue would affect users that use the --move or --remove options for clamscan, clamdscan and clamonacc.
- CVE-2020-3327
- Fixed a vulnerability in the ARJ archive-parsing module in ClamAV 0.102.3 that could cause a denial-of-service (DoS) condition. Improper bounds checking resulted in an out-of-bounds read that could cause a crash. The previous fix for this CVE in version 0.102.3 was incomplete. This fix correctly resolves the issue.
- CVE-2020-3481
- Fixed a vulnerability in the EGG archive module in ClamAV 0.102.0 - 0.102.3 that could cause a denial-of-service (DoS) condition. Improper error handling could cause a crash due to a NULL pointer dereference. This vulnerability is mitigated for those using the official ClamAV signature databases because the file type signatures in daily.cvd will not enable the EGG archive parser in affected versions.

This Pre-Release Announcement provides advance information about the Oracle Critical Patch Update for July 2020, which will be released on Tuesday, July 14, 2020.
The IPV6_2292PKTOPTIONS set handler was missing synchronization, so racing accesses could modify freed memory.
A malicious user application could trigger memory corruption, leading to privilege escalation.
posix_spawnp spawns a new thread with a limited stack allocated on the heap before delegating to execvp for the final execution within that thread.
execvp would previously make unbounded allocations on the stack, directly proportional to the length of the user-controlled PATH environment variable.
Long values in the user-controlled PATH environment variable cause posix_spawnp to write beyond the end of stack that was allocated, ultimately overflowing the heap-allocated stack with a direct copy of the value stored in PATH.

Manuel Pégourié-Gonnard reports:
The scalar multiplication function in Mbed TLS accepts a random number generator (RNG) as an optional argument and, if provided, uses it to protect against some attacks.
It is the caller's responsibility to provide a RNG if protection against side-channel attacks is desired; however two groups of functions in Mbed TLS itself fail to pass a RNG:
- mbedtls_pk_parse_key() and mbedtls_pk_parse_keyfile()
- mbedtls_ecp_check_pub_priv() and mbedtls_pk_check_pair()
When those functions are called, scalar multiplication is computed without randomisation, a number of old and new attacks apply, allowing a powerful local attacker to fully recover the private key.

Matrix developers report:
Due to the two security issues highlighted below, server administrators are encouraged to update Synapse. We are not aware of these vulnerabilities being exploited in the wild.
- A malicious homeserver could force Synapse to reset the state in a room to a small subset of the correct state. This affects all Synapse deployments which federate with untrusted servers.
- HTML pages served via Synapse were vulnerable to clickjacking attacks. This predominantly affects homeservers with single-sign-on enabled, but all server administrators are encouraged to upgrade.
GitHub Security Lab reports:

Simon Tatham reports:
[Release 0.74] fixes the following security issues:
- New configuration option to disable PuTTY's default policy of changing its host key algorithm preferences to prefer keys it already knows. (There is a theoretical information leak in this policy.) [CVE-2020-14002]
- In some situations an SSH server could cause PuTTY to access freed mdmory by pretending to accept an SSH key and then refusing the actual signature. It can only happen if you're using an SSH agent.

curl security problems:
CVE-2020-8169: Partial password leak over DNS on HTTP redirect
libcurl can be tricked to prepend a part of the password to the host name before it resolves it, potentially leaking the partial password over the network and to the DNS server(s).
libcurl can be given a username and password for HTTP authentication when requesting an HTTP resource - used for HTTP Authentication such as Basic, Digest, NTLM and similar. The credentials are set, either together with CURLOPT_USERPWD or separately with CURLOPT_USERNAME and CURLOPT_PASSWORD. Important detail: these strings are given to libcurl as plain C strings and they are not supposed to be URL encoded.
In addition, libcurl also allows the credentials to be set in the URL, using the standard RFC 3986 format: http://user:password@host/path. In this case, the name and password are URL encoded as that's how they appear in URLs.
If the options are set, they override the credentials set in the URL.
Internally, this is handled by storing the credentials in the "URL object" so that there is only a single set of credentials stored associated with this single URL.
When libcurl handles a relative redirect (as opposed to an absolute URL redirect) for an HTTP transfer, the server is only sending a new path to the client and that path is applied on to the existing URL. That "applying" of the relative path on top of an absolute URL is done by libcurl first generating a full absolute URL out of all the components it has, then it applies the redirect and finally it deconstructs the URL again into its separate components.
This security vulnerability originates in the fact that curl did not correctly URL encode the credential data when set using one of the curl_easy_setopt options described above. This made curl generate a badly formatted full URL when it would do a redirect and the final re-parsing of the URL would then go bad and wrongly consider a part of the password field to belong to the host name.
The wrong host name would then be used in a name resolve lookup, potentially leaking the host name + partial password in clear text over the network (if plain DNS was used) and in particular to the used DNS server(s).
CVE-2020-8177: curl overwrite local file with -J
curl can be tricked by a malicious server to overwrite a local file when using -J (--remote-header-name) and -i (--include) in the same command line.
The command line tool offers the -J option that saves a remote file using the file name present in the Content-Disposition: response header. curl then refuses to overwrite an existing local file using the same name, if one already exists in the current directory.
The -J flag is designed to save a response body, and so it doesn't work together with -i and there's logic that forbids it. However, the check is flawed and doesn't properly check for when the options are used in the reversed order: first using -J and then -i were mistakenly accepted.
The result of this mistake was that incoming HTTP headers could overwrite a local file if one existed, as the check to avoid the local file was done first when body data was received, and due to the mistake mentioned above, it could already have received and saved headers by that time.
The saved file would only get response headers added to it, as it would abort the saving when the first body byte arrives. A malicious server could however still be made to send back virtually anything as headers and curl would save them like this, until the first CRLF-CRLF sequence appears.
(Also note that -J needs to be used in combination with -O to have any effect.)

ISC reports:
The asterisk character ("*") is allowed in DNS zone files, where it is most commonly present as a wildcard at a terminal node of the Domain Name System graph. However, the RFCs do not require and BIND does not enforce that an asterisk character be present only at a terminal node.
A problem can occur when an asterisk is present in an empty non-terminal location within the DNS graph. If such a node exists, after a series of queries, named can reach an inconsistent state that results in the failure of an assertion check in rbtdb.c, followed by the program exiting due to the assertion failure.
ISC reports:
An assertion check in BIND (that is meant to prevent going beyond the end of a buffer when processing incoming data) can be incorrectly triggered by a large response during zone transfer.
LibreOffice reports:
Two flaws were found in LibreOffice:
- CVE-2020-12802: remote graphics contained in docx format retrieved in 'stealth mode'
- CVE-2020-12803: XForms submissions could overwrite local files
sqlite3 update:
Various security issues could be used by an attacker to cause SQLite to crash, resulting in a denial of service, or possibly execute arbitrary code.
Node.js reports:
Updates are now available for all supported Node.js release lines for the following issues.
TLS session reuse can lead to host certificate verification bypass (High) (CVE-2020-8172)
The 'session' event could be emitted before the 'secureConnect' event. It should not be, because the connection may fail to be authorized. If it was saved an authorized connection could be established later with the session ticket. Note that the https agent caches sessions, so is vulnerable to this.
The 'session' event will now only be emitted after the 'secureConnect' event, and only for authorized connections.
HTTP/2 Large Settings Frame DoS (Low) (CVE-2020-11080)
Receiving unreasonably large HTTP/2 SETTINGS frames can consume 100% CPU to process all the settings, blocking all other activities until complete.
The HTTP/2 session frame is limited to 32 settings by default. This can be configured if necessary using the maxSettings option.
napi_get_value_string_*() allows various kinds of memory corruption (High) (CVE-2020-8174)
Calling napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer.
A exploit has not been reported and it may be difficult but the following is suggested:
- All users of LTS Node.js versions should update to the versions announced in this security post. This will address the issue for any non pre-built add-on.
- Maintainers who support EOL Node.js versions and/or build against a version of Node.js that did not support N-API internally should update to use the new versions of node-addon-api 1.x and 2.x that will be released soon after this announcement.
ICU-20958 Prevent SEGV_MAPERR in append (High) (CVE-2020-10531)
An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.
Fix was applied to 10.x in an abundance of caution, even though there is no known way to trigger the overflow in 10.x.

git security advisory reports:
Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that contain an encoded newline can inject unintended values into the credential helper protocol stream, causing the credential helper to retrieve the password for one server for an HTTP request being made to another server, resulting in credentials for the former being sent to the latter.
git security advisory reports:
Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to helpers, missing hostname and protocol fields. Many helpers will interpret this as matching any URL, and will return some unspecified stored password, leaking the password to an attacker's server.
The GnuTLS project reports:
It was found that GnuTLS 3.6.4 introduced a regression in the TLS protocol implementation. This caused the TLS server to not securely construct a session ticket encryption key considering the application supplied secret, allowing a MitM attacker to bypass authentication in TLS 1.3 and recover previous conversations in TLS 1.2.

Javier Moreno discovered a vulnerability in Sympa web interface that can cause denial of service (DoS) attack.
By submitting requests with malformed parameters, this flaw allows to create junk files in Sympa's directory for temporary files. And particularly by tampering token to prevent CSRF, it allows to originate exessive notification messages to listmasters.
A vulnerability has been discovered in Sympa web interface by which attacker can execute arbitrary code with root privileges. Sympa uses two sorts of setuid wrappers:
The FastCGI wrappers wwsympa-wrapper.fcgi and sympa_soap_server-wrapper.fcgi were used to make the web interface running under privileges of a dedicated user.
The newaliases wrapper (sympa_newaliases-wrapper) allows Sympa to update the alias database with root privileges.
Since these setuid wrappers did not clear environment variables, if environment variables like PERL5LIB were injected, forged code might be loaded and executed under privileges of setuid-ed users.
PowerDNS Team reports:
CVE-2020-10995: An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect.
CVE-2020-12244: An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer. This would allow an attacker in position of man-in-the-middle to send a NXDOMAIN answer for a name that does exist, bypassing DNSSEC validation.
CVE-2020-10030: An issue has been found in PowerDNS Authoritative Server allowing an attacker with enough privileges to change the system's hostname to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not null-terminate the returned string if the hostname is larger than the supplied buffer. Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname is always null-terminated. Under some conditions this issue can lead to the writing of one null-byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution.

Aki Tuomi reports:
Vulnerability Details: Sending malformed NOOP command causes crash in submission, submission-login or lmtp service. Risk: Remote attacker can keep submission-login service down, causing denial of service attack. For lmtp the risk is neglible, as lmtp is usually behind a trusted MTA. Steps to reproduce: Send ``NOOP EE"FY`` to submission port, or similarly malformed command.
Vulnerability Details: Sending command followed by sufficient number of newlines triggers a use-after-free bug that might crash submission-login, submission or lmtp service. Risk: Remote attacker can keep submission-login service down, causing denial of service attack. For lmtp the risk is neglible, as lmtp is usually behind a trusted MTA. Steps to reproduce: This can be currently reproduced with ASAN or Valgrind. Reliable way to crash has not yet been discovered.
Vulnerability Details: Sending mail with empty quoted localpart causes submission or lmtp component to crash. Risk: Malicious actor can cause denial of service to mail delivery by repeatedly sending mails with bad sender or recipient address. Steps to reproduce: Send mail with envelope sender or recipient as <""@example.org>. Workaround: For submission there is no workaround, but triggering the bug requires valid credentials. For lmtp, one can implement sufficient filtering on MTA level to prevent mails with such addresses from ending up in LMTP delivery.
Micah Snyder reports:
CVE-2020-3327: Fixed a vulnerability in the ARJ archive-parsing module in ClamAV 0.102.2 that could cause a denial-of-service condition.

F-Secure reports:
CVE-2020-11651 - Authentication bypass vulnerabilities
The ClearFuncs class processes unauthenticated requests and unintentionally exposes the _send_pub() method, which can be used to queue messages directly on the master publish server. Such messages can be used to trigger minions to run arbitrary commands as root.
The ClearFuncs class also exposes the method _prep_auth_info(), which returns the "root key" used to authenticate commands from the local root user on the master server. This "root key" can then be used to remotely call administrative commands on the master server. This unintentional exposure provides a remote un-authenticated attacker with root-equivalent access to the salt master.
CVE-2020-11652 - Directory traversal vulnerabilities
The wheel module contains commands used to read and write files under specific directory paths. The inputs to these functions are concatenated with the target directory and the resulting path is not canonicalized, leading to an escape of the intended path restriction.
The get_token() method of the salt.tokens.localfs class (which is exposed to unauthenticated requests by the ClearFuncs class) fails to sanitize the token input parameter which is then used as a filename, allowing insertion of ".." path elements and thus reading of files outside of the intended directory. The only restriction is that the file has to be deserializable by salt.payload.Serial.loads().
Tobias Stöckmann reports:
I have discovered a way to trigger an out of boundary write while parsing a huge json file through a malicious input source. It can be triggered if an attacker has control over the input stream or if a huge load during filesystem operations can be triggered.
Typo3 News:
CVE-2020-11063: TYPO3-CORE-SA-2020-001: Information Disclosure in Password Reset

CVE-2020-11064: TYPO3-CORE-SA-2020-002: Cross-Site Scripting in Form Engine
It has been discovered that HTML placeholder attributes containing data of other database records are vulnerable to cross-site scripting. A valid backend user account is needed to exploit this vulnerability.
CVE-2020-11065: TYPO3-CORE-SA-2020-003: Cross-Site Scripting in Link Handling
It has been discovered that link tags generated by typolink functionality are vulnerable to cross-site scripting - properties being assigned as HTML attributes have not been parsed correctly.
CVE-2020-11066: TYPO3-CORE-SA-2020-004: Class destructors causing side-effects when being unserialized
Calling unserialize() on malicious user-submitted content can result in the following scenarios:
- trigger deletion of arbitrary directory in file system (if writable for web server)
- trigger message submission via email using identity of web site (mail relay)
Another insecure deserialization vulnerability is required to actually exploit mentioned aspects.
CVE-2020-11067: TYPO3-CORE-SA-2020-005: Insecure Deserialization in Backend User Settings
It has been discovered that backend user settings (in $BE_USER->uc) are vulnerable to insecure deserialization. In combination with vulnerabilities of 3rd party components this can lead to remote code execution. A valid backend user account is needed to exploit this vulnerability.
CVE-2020-11069: TYPO3-CORE-SA-2020-006: Same-Site Request Forgery to Backend User Interface
It has been discovered that the backend user interface and install tool are vulnerable to same-site request forgery. A backend user can be tricked into interacting with a malicious resource an attacker previously managed to upload to the web server - scripts are then executed with the privileges of the victims’ user session.
In a worst case scenario new admin users can be created which can directly be used by an attacker. The vulnerability is basically a cross-site request forgery (CSRF) triggered by a cross-site scripting vulnerability (XSS) - but happens on the same target host - thus, it’ actually a same-site request forgery (SSRF).
Malicious payload such as HTML containing JavaScript might be provided by either an authenticated backend user or by a non-authenticated user using a 3rd party extension - e.g. file upload in a contact form with knowing the target location.
The attacked victim requires an active and valid backend or install tool user session at the time of the attack to be successful.
Requests to create cryptography sessions using a MAC did not validate the user-supplied MAC key length. The cryptodev module allocates a buffer whose size is this user-suppled length.
An unprivileged process can trigger a kernel panic.
A race condition permitted a data structure in the kernel to be used after it was freed by the cryptodev module.
An unprivileged process can overwrite arbitrary kernel memory.
The SCTP layer does improper checking when an application tries to update a shared key. Therefore an unprivileged local user can trigger a use-after- free situation, for example by specific sequences of updating shared keys and closing the SCTP association.
Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.
The FTP packet handler in libalias incorrectly calculates some packet lengths. This may result in disclosing small amounts of memory from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).
A malicious attacker could send specially constructed packets that exploit the erroneous calculation allowing the attacker to disclose small amount of memory either from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).
libalias(3) packet handlers do not properly validate the packet length before accessing the protocol headers. As a result, if a libalias(3) module does not properly validate the packet length before accessing the protocol header, it is possible for an out of bound read or write condition to occur.
A malicious attacker could send specially constructed packets that exploit the lack of validation allowing the attacker to read or write memory either from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).
Qutebrowser developers report:
After a certificate error was overridden by the user, qutebrowser displays the URL as yellow (colors.statusbar.url.warn.fg). However, when the affected website was subsequently loaded again, the URL was mistakenly displayed as green (colors.statusbar.url.success_https). While the user already has seen a certificate error prompt at this point (or set content.ssl_strict to false which is not recommended), this could still provide a false sense of security.
Python reports:
An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the host component of a URL) followed by an HTTP header.

Wagtail release notes:
CVE-2020-11037: Potential timing attack on password-protected private pages
This release addresses a potential timing attack on pages or documents that have been protected with a shared password through Wagtail's "Privacy" controls. This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. (This is understood to be feasible on a local network, but not on the public internet.)
Mark Sapiro reports:
A content injection vulnerability via the options login page has been discovered and reported by Vishal Singh.
An issue similar to CVE-2018-13796 exists at different endpoint & param. It can lead to a phishing attack.
(added 2020-05-07) This is essentially the same as https://bugs.launchpad.net/mailman/+bug/1873722 except the vector is the private archive login page and the attack only succeeds if the list's roster visibility (private_roster) setting is 'Anyone'.

- Send a specifically crafter request to the microdns service discovery, potentially triggering various memory management issues
Impact
If successful, a malicious third party could trigger either a crash of VLC or an arbitratry code execution with the privileges of the target user.
While these issues in themselves are most likely to just crash the player, we can't exclude that they could be combined to leak user informations or remotely execute code. ASLR and DEP help reduce the likelyness of code execution, but may be bypassed.
We have not seen exploits performing code execution through these vulnerabilities

Riccardo Schirone (https://github.com/ret2libc) reports:
In FullLoader python/object/new constructor, implemented by construct_python_object_apply, has support for setting the state of a deserialized instance through the set_python_instance_state method. After setting the state, some operations are performed on the instance to complete its initialization, however it is possible for an attacker to set the instance' state in such a way that arbitrary code is executed by the FullLoader.
This patch tries to block such attacks in FullLoader by preventing set_python_instance_state from setting arbitrar properties. It implements a blacklist that includes extend method (called by construct_python_object_apply) and all special methods (e.g. __set__, __setitem__, etc.).
Users who need special attributes being set in the state of a deserialized object can still do it through the UnsafeLoader, which however should not be used on untrusted input. Additionally, they can subclass FullLoader and redefine state_blacklist_regexp to include the additional attributes they need, passing the subclassed loader to yaml.load.
Bleach developers reports:
bleach.clean behavior parsing style attributes could result in a regular expression denial of service (ReDoS).
Calls to bleach.clean with an allowed tag with an allowed style attribute are vulnerable to ReDoS. For example, bleach.clean(..., attributes={'a': ['style']}).

Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1 allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking.
Wagtail release notes:
CVE-2020-11001: Possible XSS attack via page revision comparison view
This release addresses a cross-site scripting (XSS) vulnerability on the page revision comparison view within the Wagtail admin interface. A user with a limited-permission editor account for the Wagtail admin could potentially craft a page revision history that, when viewed by a user with higher privileges, could perform actions with that user credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.
NVD reports:
Libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request.
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognized signature algorithm is received from the peer.
A malicious peer could exploit the NULL pointer dereference crash, causing a denial of service attack.
Incomplete packet data validation may result in accessing out-of-bounds memory (CVE-2019-5614) or may access memory after it has been freed (CVE-2019-15874).
Access to out of bounds or freed mbuf data can lead to a kernel panic or other unpredictable results.
Twisted developers reports:
All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability.
The HTTP/2 server implementation now enforces TCP flow control on control frame messages and times out clients that send invalid data without reading responses. This closes CVE-2019-9512 (Ping Flood), CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood). Thanks to Jonathan Looney and Piotr Sikora.
twisted.web.http was subject to several request smuggling attacks. Requests with multiple Content-Length headers were allowed (CVE-2020-10108, thanks to Jake Miller from Bishop Fox and ZeddYu Lu for reporting this) and now fail with a 400; requests with a Content-Length header and a Transfer-Encoding header honored the first header (CVE-2020-10109, thanks to Jake Miller from Bishop Fox for reporting this) and now fail with a 400; requests whose Transfer-Encoding header had a value other than "chunked" and "identity" (thanks to ZeddYu Lu) were allowed and now fail with a 400.
The libssh team reports (originally reported by Yasheng Yang from Google):

Drupal Security Team reports:
The Drupal project uses the third-party library CKEditor, which has released a security improvement that is needed to protect some Drupal configurations.
Vulnerabilities are possible if Drupal is configured to use the WYSIWYG CKEditor for your site's users. An attacker that can createor edit content may be able to exploit this Cross Site Scripting (XSS) vulnerability to target users with access to the WYSIWYG CKEditor, and this may include site admins with privileged access.
The latest versions of Drupal update CKEditor to 4.14 to mitigate the vulnerabilities.
Borja Tarraso reports:
A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes "ansible-vault edit", another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the file before recreating it insecurely. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.
Borja Tarraso reports:
A flaw was found in Ansible 2.7.16 and prior, 2.8.8 and prior, and 2.9.5 and prior when a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs.
Borja Tarraso reports:
A flaw was found in Ansible 2.7.17 and prior, 2.8.9 and prior, and 2.9.6 and prior when using the Extract-Zip function from the win_unzip module as the extracted file(s) are not checked if they belong to the destination folder. An attacker could take advantage of this flaw by crafting an archive anywhere in the file system, using a path traversal. This issue is fixed in 2.10.
Google Chrome Releases reports:
[1067851] Critical CVE-2020-6457: Use after free in speech recognizer. Reported by Leecraso and Guang Gong of Alpha Lab, Qihoo 360 on 2020-04-04
Lev Stipakov and Gert Doering report:
There is a time frame between allocating peer-id and initializing data channel key (which is performed on receiving push request or on async push-reply) in which the existing peer-id float checks do not work right.
If a "rogue" data channel packet arrives during that time frame from another address and with same peer-id, this would cause client to float to that new address.
The net effect of this behaviour is that the VPN session for the "victim client" is broken. Since the "attacker client" does not have suitable keys, it can not inject or steal VPN traffic from the other session. The time window is small and it can not be used to attack a specific client's session, unless some other way is found to make it disconnect and reconnect first.
Manuel Pégourié-Gonnard reports:
An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) can fully recover an ECDSA private key after observing a number of signature operations.

When parsing certain JSON documents, the json gem (including the one bundled with Ruby) can be coerced into creating arbitrary objects in the target system.
This is the same issue as CVE-2013-0269. The previous fix was incomplete, which addressed JSON.parse(user_input), but didn’t address some other styles of JSON parsing including JSON(user_input) and JSON.parse(user_input, nil).
See CVE-2013-0269 in detail. Note that the issue was exploitable to cause a Denial of Service by creating many garbage-uncollectable Symbol objects, but this kind of attack is no longer valid because Symbol objects are now garbage-collectable. However, creating arbitrary bjects may cause severe security consequences depending upon the application code.
Please update the json gem to version 2.3.0 or later. You can use gem update json to update it. If you are using bundler, please add gem "json", ">= 2.3.0" to your Gemfile.

Puppetlabs reports:
Puppet Server and PuppetDB provide useful performance and debugging information via their metrics API endpoints. For PuppetDB this may contain things like hostnames. Puppet Server reports resource names and titles for defined types (which may contain sensitive information) as well as function names and class names. Previously, these endpoints were open to the local network.
PE 2018.1.13 & 2019.4.0, Puppet Server 6.9.1 & 5.3.12, and PuppetDB 6.9.1 & 5.2.13 disable trapperkeeper-metrics /v1 metrics API and only allows /v2 access on localhost by default.
Puppetlabs reports:
Previously, Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the `default` node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting `strict_hostname_checking = true` in `puppet.conf` on your Puppet master.
Puppet 6.13.0 changes the default behavior for strict_hostname_checking from false to true. It is recommended that Puppet Open Source and Puppet Enterprise users that are not upgrading still set strict_hostname_checking to true to ensure secure behavior.
A missing NUL-termination check for the jail_set(2) configration option "osrelease" may return more bytes when reading the jail configuration back with jail_get(2) than were originally set.
For jails with a non-default setting of children.max > 0 ("nested jails") a superuser inside a jail can create a jail and may be able to read and take advantage of exposed kernel memory.
Incorrect use of a potentially user-controlled pointer in the kernel allowed vnet jailed users to panic the system and potentially execute aribitrary code in the kernel.
Users with root level access (or the PRIV_NET_IFCREATE privilege) can panic the system, or potentially escape the jail or execute arbitrary code with kernel priviliges.
The driver-specific ioctl(2) command handlers in ixl(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation.
The ixl(4) handler permits unprivileged users to trigger updates to the device's non-volatile memory (NVM).
The driver-specific ioctl(2) command handlers in oce(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation.
The oce(4) handler permits unprivileged users to send passthrough commands to device firmware.
When a TCP server transmits or retransmits a TCP SYN-ACK segment over IPv6, the Traffic Class field is not initialized. This also applies to challenge ACK segments, which are sent in response to received RST segments during the TCP connection setup phase.
For each TCP SYN-ACK (or challenge TCP-ACK) segment sent over IPv6, one byte of kernel memory is transmitted over the network.
* ``bleach.clean`` behavior parsing embedded MathML and SVG content with RCDATA tags did not match browser behavior and could result in a mutation XSS.
Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or ``svg`` tags and one or more of the RCDATA tags ``script``, ``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or ``xmp`` in the allowed tags whitelist were vulnerable to a mutation XSS.
* ``bleach.clean`` behavior parsing ``noscript`` tags did not match browser behavior.
Calls to ``bleach.clean`` allowing ``noscript`` and one or more of the raw text tags (``title``, ``textarea``, ``script``, ``style``, ``noembed``, ``noframes``, ``iframe``, and ``xmp``) were vulnerable to a mutation XSS.
Jon Siwek of Corelight reports:
This release addresses the following security issues:
- Potential Denial of Service due to memory leak in DNS TSIG message parsing.
- Potential Denial of Service due to memory leak (or assertion when compiling with assertions enabled) when receiving a second SSH KEX message after a first.
- Potential Denial of Service due to buffer read overflow and/or memory leaks in Kerberos analyzer. The buffer read overflow could occur when the Kerberos message indicates it contains an IPv6 address, but does not send enough data to parse out a full IPv6 address. A memory leak could occur when processing KRB_KDC_REQ KRB_KDC_REP messages for message types that do not match a known/expected type.
- Potential Denial of Service when sending many zero-length SSL/TLS certificate data. Such messages underwent the full Zeek file analysis treatment which is expensive (and meaninguless here) compared to how cheaply one can "create" or otherwise indicate many zero-length contained in an SSL message.
- Potential Denial of Service due to buffer read overflow in SMB transaction data string handling. The length of strings being parsed from SMB messages was trusted to be whatever the message claimed instead of the actual length of data found in the message.
- Potential Denial of Service due to null pointer dereference in FTP ADAT Base64 decoding.
- Potential Denial of Service due buffer read overflow in FTP analyzer word/whitespace handling. This typically won't be a problem in most default deployments of Zeek since the FTP analyzer receives data from a ContentLine (NVT) support analyzer which first null-terminates the buffer used for further FTP parsing.
Albert Astals Cid:
Okular can be tricked into executing local binaries via specially crafted PDF files.
This binary execution can require almost no user interaction.
No parameters can be passed to those local binaries.
We have not been able to identify any binary that will cause actual damage, be it in the hardware or software level, when run without parameters.
We remain relatively confident that for this issue to do any actual damage, it has to run a binary specially crafted. That binary must have been deployed to the user system via another method, be it the user downloading it directly as an email attachment, webpage download, etc. or by the system being already compromised.

Node.js reports:
Updates are now available for all active Node.js release lines for the following issues.
HTTP request smuggling using malformed Transfer-Encoding header (Critical) (CVE-2019-15605)HTTP request smuggling using malformed Transfer-Encoding header (Critical) (CVE-2019-15605)
Affected Node.js versions can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system.
HTTP header values do not have trailing OWS trimmed (High) (CVE-2019-15606)
Optional whitespace should be trimmed from HTTP header values. Its presence may allow attackers to bypass security checks based on HTTP header values.
Remotely trigger an assertion on a TLS server with a malformed certificate string (High) (CVE-2019-15604)
Connecting to a NodeJS TLS server with a client certificate that has a type 19 string in its subjectAltName will crash the TLS server if it tries to read the peer certificate.
Strict HTTP header parsing (None)
Increase the strictness of HTTP header parsing. There are no known vulnerabilities addressed, but lax HTTP parsing has historically been a source of problems. Some commonly used sites are known to generate invalid HTTP headers, a --insecure-http-parser CLI option or insecureHTTPParser http option can be used if necessary for interoperability, but is not recommended.

nwtime.org reports:
Three ntp vulnerabilities, Depending on configuration, may have little impact up to termination of the ntpd process.
NTP Bug 3610: Process_control() should exit earlier on short packets. On systems that override the default and enable ntpdc (mode 7) fuzz testing detected that a short packet will cause ntpd to read uninitialized data.
NTP Bug 3596: An unauthenticated unmonitored ntpd is vulnerable to attack on IPv4 with highly predictable transmit timestamps. An off-path attacker who can query time from the victim's ntp which receives time from an unauthenticated time source must be able to send from a spoofed IPv4 address of upstream ntp server and and the victim must be able to process a large number of packets with the spoofed IPv4 address of the upstream server. After eight or more successful attacks in a row the attacker can either modify the victim's clock by a small amount or cause ntpd to terminate. The attack is especially effective when unusually short poll intervals have been configured.
NTP Bug 3592: The fix for https://bugs.ntp.org/3445 introduced a bug such that a ntp can be prevented from initiating a time volley to its peer resulting in a DoS.
All three NTP bugs may result in DoS or terimation of the ntp daemon.
Librsvg2 developers reports:
Backport the following fixes from 2.46.x:
Librsvg now has limits on the number of loaded XML elements, and the number of referenced elements within an SVG document. This is to mitigate malicious SVGs which try to consume all memory, and those which try to consume an exponential amount of CPU time.
Fix stack exhaustion with circular references in <use> elements.
Fix a denial-of-service condition from exponential explosion of rendered elements, through nested use of SVG <use> elements in malicious SVGs. This is similar to the XML "billion laughs attack" but for SVG instancing.

OpenSMTPD developers reports:
An out of bounds read in smtpd allows an attacker to inject arbitrary commands into the envelope file which are then executed as root. Separately, missing privilege revocation in smtpctl allows arbitrary commands to be run with the _smtpq group.
An unprivileged local attacker can read the first line of an arbitrary file (for example, root's password hash in /etc/master.passwd) or the entire contents of another user's file (if this file and /var/spool/smtpd/ are on the same filesystem).
Janos Follath reports:
If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported.
The attack only requires access to fine grained measurements to cache usage. Therefore the attack might be applicable to a scenario where Mbed TLS is running in TrustZone secure world and the attacker controls the normal world or possibly when Mbed TLS is part of a hypervisor and the adversary has full control of a guest OS.
Janos Follath reports:
Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it (as it is smaller than RSA keys and not guaranteed to have only large prime factors), and then, by brute force, recover the key.
The WeeChat project reports:
Buffer overflow when receiving a malformed IRC message 324 (channel mode). (CVE-2020-8955)
Buffer overflow when a new IRC message 005 is received with longer nick prefixes.
Crash when receiving a malformed IRC message 352 (WHO).
The WebKitGTK project reports multiple vulnerabilities.
Due to incorrect initialization of a stack data structure, up to 20 bytes of kernel data stored previously stored on the stack will be exposed to a crashing user process.
Sensitive kernel data may be disclosed.
A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint.
The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause an action that was intentionally performed once to be repeated.
A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers.
An attacker in control of the URL to be fetched (possibly via HTTP redirect) may cause a heap buffer overflow, resulting in program misbehavior or malicious code execution.
Gitlab reports:
Incorrect membership handling of group sharing feature
Aki Tuomi reports:
lib-smtp doesn't handle truncated command parameters properly, resulting in infinite loop taking 100% CPU for the process. This happens for LMTP (where it doesn't matter so much) and also for submission-login where unauthenticated users can trigger it.
Aki also reports:
Snippet generation crashes if: message is large enough that message-parser returns multiple body blocks The first block(s) don't contain the full snippet (e.g. full of whitespace) input ends with '>'
Reno Robert reports:
FreeBSD uses a two-process model for running a VM. For booting non-FreeBSD guests, a modified grub-emu is used (grub-bhyve). Grub-bhyve executes command from guest grub.cfg file. This is a security problem because grub was never written to handle inputs from OS as untrusted. In the current design, grub and guest OS works across trust boundaries. This exposes a grub to untrusted inputs from guest.
grub-bhyve (emu) is built without SDL graphics support which reduces lot of gfx attack surface, however font loading code is still accessible. Guest can provide arbitrary font file, which is parsed by grub-bhyve running as root.
In grub-core/font/font.c,
read_section_as_string()allocatessection->length + 1bytes of memory. However, untrustedsection->lengthis an unsigned 32-bit number, and the result can overflow tomalloc(0). This can result in a controlled buffer overflow via the 'loadfont' command in a guest VM grub2.cfg, eventually leading to privilege escalation from guest to host.
Reno Robert also reports:
GRUB supports commands to read and write addresses of choice. In grub-bhyve, these commands provide a way to write to arbitrary virtual addresses within the grub-bhyve process. This is another way for a guest grub2.cfg, run by the host, to eventually escalate privileges.
These vulnerabilities are mitigated by disabling the 'loadfont', 'write_dword', 'read_dword', 'inl', 'outl', and other width variants of the same functionality in grub2-bhyve.
There is also work in progress to sandbox the grub-bhyve utility such that an escaped guest ends up with nobody:nobody in a Capsium sandbox. It is not included in 0.40_8.
Mitre reports:
In libexif, there is a possible out of bounds write due to an integer overflow. This could lead to remote escalation of privilege in the media content provider with no additional execution privileges needed. User interaction is needed for exploitation.
Adobe reports:
- This update resolves a type confusion vulnerability that could lead to arbitrary code execution (CVE-2020-3757).
NGINX Team reports:
NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.
Upstream ksh93 maintainer Siteshwar Vashisht reports:
A flaw was found in the way ksh evaluates certain environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. Services and applications that allow remote unauthenticated attackers to provide one of those environment variables could allow them to exploit this issue remotely.
Micah Snyder reports:
A denial-of-service (DoS) condition may occur when using the optional credit card data-loss-prevention (DLP) feature. Improper bounds checking of an unsigned variable resulted in an out-of-bounds read, which causes a crash.
MITRE CVE reports:
Django 1.11 before 1.11.28, 2.2 before 2.2.10, and 3.0 before 3.0.3 allows SQL Injection if untrusted data is used as a StringAgg delimiter (e.g., in Django applications that offer downloads of data as a series of rows with a user-specified column delimiter). By passing a suitably crafted delimiter to a contrib.postgres.aggregates.StringAgg instance, it was possible to break escaping and inject malicious SQL.
MariaDB reports:
Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.
The libssh team reports:
In an environment where a user is only allowed to copy files and not to execute applications, it would be possible to pass a location which contains commands to be executed in additon.
When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of ssh_scp_new(), it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.
The Apache SpamAssassin project reports:
A nefarious rule configuration (.cf) files can be configured to run system commands. This issue is less stealthy and attempts to exploit the issue will throw warnings.
Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.
Todd C. Miller reports:
Sudo's pwfeedback option can be used to provide visual feedback when the user is inputting their password. For each key press, an asterisk is printed. This option was added in response to user confusion over how the standard Password: prompt disables the echoing of key presses. While pwfeedback is not enabled by default in the upstream version of sudo, some systems, such as Linux Mint and Elementary OS, do enable it in their default sudoers files.
Due to a bug, when the pwfeedback option is enabled in the sudoers file, a user may be able to trigger a stack-based buffer overflow. This bug can be triggered even by users not listed in the sudoers file. There is no impact unless pwfeedback has been enabled.

Pillow developers report:
This release addresses several security problems, as well as addressing CVE-2019-19911.
CVE-2019-19911 is regarding FPX images. If an image reports that it has a large number of bands, a large amount of resources will be used when trying to process the image. This is fixed by limiting the number of bands to those usable by Pillow.
Buffer overruns were found when processing an SGI, PCX or FLI image. Checks have been added to prevent this.
Overflow checks have been added when calculating the size of a memory block to be reallocated in the processing of a TIFF image.

A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
Theodore Y. Ts'o reports:
E2fsprogs 1.45.5 [...:] Fix a potential out of bounds write when checking a maliciously corrupted file system. This is probably not exploitable on 64-bit platforms, but may be exploitable on 32-bit binaries depending on how the compiler lays out the stack variables. (Addresses CVE-2019-5188)

Tim Wojtulewicz of Corelight reports:
Receiving DNS responses from async DNS requests (via the lookup_addr, etc BIF methods) with the TTL set to zero could cause the DNS manager to eventually stop being able to make new requests.
Specially-crafted FTP packets with excessively long usernames, passwords, or other fields could cause log writes to use large amounts of disk space.
The find_all and find_all_ordered BIF methods could take extremely large amounts of time to process incoming data depending on the size of the input.
Libde265 developer reports:
This release fixes the known CVEs below. Many of them are actually caused by the same underlying issues that manifest in different ways.
git team reports:
By feeding a crafted input to "git apply", a path outside the working tree can be overwritten as the user who is running "git apply".
git team reports:
Using a specially-crafted repository, Git can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links (c.f., CVE-2022-39253), the objects directory itself may still be a symbolic link.
These two may be combined to include arbitrary files based on known paths on the victim's filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar manner as CVE-2022-39253.
git team reports:
gitattributes are used to define unique attributes corresponding to paths in your repository. These attributes are defined by .gitattributes file(s) within your repository.
The parser used to read these files has multiple integer overflows, which can occur when parsing either a large number of patterns, a large number of attributes, or attributes with overly-long names.
These overflows may be triggered via a malicious .gitattributes file. However, Git automatically splits lines at 2KB when reading .gitattributes from a file, but not when parsing it from the index. Successfully exploiting this vulnerability depends on the location of the .gitattributes file in question.
This integer overflow can result in arbitrary heap reads and writes, which may result in remote code execution.
The git team reports:
git log has the ability to display commits using an arbitrary format with its --format specifiers. This functionality is also exposed to git archive via the export-subst gitattribute.
When processing the padding operators (e.g., %<(, %<|(, %>(, %>>(, or %><( ), an integer overflow can occur in pretty.c::format_and_pad_commit() where a size_t is improperly stored as an int, and then added as an offset to a subsequent memcpy() call.
This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g., git log --format=...). It may also be triggered indirectly through git archive via the export-subst mechanism, which expands format specifiers inside of files within the repository during a git archive.
This integer overflow can result in arbitrary heap writes, which may result in remote code execution.
The Gitea team reports:
This PR refactors and improves the password hashing code within gitea and makes it possible for server administrators to set the password hashing parameters.
In addition it takes the opportunity to adjust the settings for pbkdf2 in order to make the hashing a little stronger.
Add command to bulk set must-change-password
As part of administration sometimes it is appropriate to forcibly tell users to update their passwords.
This PR creates a new command gitea admin user must-change-password which will set the MustChangePassword flag on the provided users.
The Go project reports:
A request smuggling attack is possible when using MaxBytesHandler. When using MaxBytesHandler, the body of an HTTP request is not fully consumed. When the server attempts to read HTTP2 frames from the connection, it will instead be reading the body of the HTTP request, which could be attacker-manipulated to represent arbitrary HTTP2 requests.
The Rundeck project reports:
This release updates both Community and Enterprise with the latest Log4J to address CVE-2021-44832 by updating it to 2.17.1.

- Fixed a possible remote code execution vulnerability in the HFS+ file parser.
- CVE-2023-20052
- Fixed a possible remote information leak vulnerability in the DMG file parser.
The Go project reports:
path/filepath: path traversal in filepath.Clean on Windows
On Windows, the filepath.Clean function could transform an invalid path such as a/../c:/b into the valid path c:\b. This transformation of a relative (if invalid) path into an absolute path could enable a directory traversal attack. The filepath.Clean function will now transform this path into the relative (but still invalid) path .\c:\b.
net/http, mime/multipart: denial of service from excessive resource consumption
Multipart form parsing with mime/multipart.Reader.ReadForm can consume largely unlimited amounts of memory and disk files. This also affects form parsing in the net/http package with the Request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue.
crypto/tls: large handshake records may cause panics
Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses.
net/http: avoid quadratic complexity in HPACK decoding
A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.

PostgreSQL Project reports:
A modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. When a libpq client application has a Kerberos credential cache and doesn't explicitly disable option gssencmode, a server can cause libpq to over-read and report an error message containing uninitialized bytes from and following its receive buffer. If libpq's caller somehow makes that message accessible to the attacker, this achieves a disclosure of the over-read bytes. We have not confirmed or ruled out viability of attacks that arrange for a crash or for presence of notable, confidential information in disclosed bytes.
Grafana Labs reports:
On 2022-12-16 during an internal audit of Grafana, a member of the security team found a stored XSS vulnerability affecting the core plugin GeoMap.
The stored XSS vulnerability was possible due to SVG-files weren't properly sanitized and allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana instance.
Grafana Labs reports:
A third-party penetration test of Grafana found a vulnerability in the snapshot functionality. The value of the originalUrl parameter is automatically generated. The purpose of the presented originalUrl parameter is to provide a user who views the snapshot with the possibility to click on the Local Snapshot button in the Grafana web UI and be presented with the dashboard that the snapshot captured. The value of the originalUrl parameter can be arbitrarily chosen by a malicious user that creates the snapshot. (Note: This can be done by editing the query thanks to a web proxy like Burp.)
We have assessed this vulnerability as having a CVSS score of 6.7 MEDIUM (CVSS:6.7/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:L).
The OpenBSD project reports:
A malicious certificate revocation list or timestamp response token would allow an attacker to read arbitrary memory.

The OpenSSL project reports:
X.400 address type confusion in X.509 GeneralName (CVE-2023-0286) (High): There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING.
Timing Oracle in RSA Decryption (CVE-2022-4304) (Moderate): A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
X.509 Name Constraints Read Buffer Overflow (CVE-2022-4203) (Moderate): A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
Use-after-free following BIO_new_NDEF (CVE-2023-0215) (Moderate): The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications.
Double free after calling PEM_read_bio_ex (CVE-2022-4450) (Moderate): The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the "name" (e.g. "CERTIFICATE"), any header data and the payload data. If the function succeeds then the "name_out", "header" and "data" arguments are populated with pointers to buffers containing the relevant decoded data. The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a buffer that has already been freed. If the caller also frees this buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service attack.
Invalid pointer dereference in d2i_PKCS7 functions (CVE-2023-0216) (Moderate): An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions.
NULL dereference validating DSA public key (CVE-2023-0217) (Moderate): An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVP_PKEY_public_check() function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted sources which could allow an attacker to cause a denial of service attack.
NULL dereference during PKCS7 data verification (CVE-2023-0401) (Moderate): A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash.

Prometheus team reports:
Prometheus and its exporters can be secured by a web.yml file that specifies usernames and hashed passwords for basic authentication. Passwords are hashed with bcrypt, which means that even if you have access to the hash, it is very hard to find the original password back. Passwords are hashed with bcrypt, which means that even if you have access to the hash, it is very hard to find the original password back. However, a flaw in the way this mechanism was implemented in the exporter toolkit makes it possible with people who know the hashed password to authenticate against Prometheus. A request can be forged by an attacker to poison the internal cache used to cache the computation of hashes and make subsequent requests successful. This cache is used in both happy and unhappy scenarios in order to limit side channel attacks that could tell an attacker if a user is present in the file or not.

Tim Wojtulewicz of Corelight reports:
A missing field in the SMB FSControl script-land record could cause a heap buffer overflow when receiving packets containing those header types.
Receiving a series of packets that start with HTTP/1.0 and then switch to HTTP/0.9 could cause Zeek to spend a large amount of time processing the packets.
Receiving large numbers of FTP commands sequentially from the network with bad data in them could cause Zeek to spend a large amount of time processing the packets, and generate a large amount of events.

Plex Security Team reports:
We have recently been made aware of a security vulnerability in Plex Media Server versions prior to 1.25.0 that could allow a local Windows user to obtain administrator privileges without authorization. To be clear, this required the user to already have local, physical access to the computer (just with a different user account on Windows). There are no indications that this exploit could be used from a remote machine.
Plex Media Server versions 1.25.0.5282 and newer are not subject to this vulnerability, and feature additional hardening to prevent similar issues from occurring in the future. Users running older server versions are encouraged to update their Plex Media Server installations.

MITRE reports:
NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the "/rrdp" endpoint. Prior to 0.12.1 a direct query for any existing directory under "/rrdp/", rather than an RRDP file such as "/rrdp/notification.xml" as would be expected, causes Krill to crash. If the built-in "/rrdp" endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated. .
MITRE reports:
It seems #90 is not completely fixed in 7.8. (that is, even after CVE-2017-1000501 and CVE-2020-29600 are fixed). In AWStats through 7.8, cgi-bin/awstats.pl?config= accepts a partial absolute pathname (omitting the initial /etc), even though it was intended to only read a file in the /etc/awstats/awstats.conf format. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000501 and CVE-2020-29600.

Peter Ammon reports:
fish is a command line shell. fish version 3.1.0 through version 3.3.1 is vulnerable to arbitrary code execution. git repositories can contain per-repository configuration that change the behavior of git, including running arbitrary commands. When using the default configuration of fish, changing to a directory automatically runs git commands in order to display information about the current repository in the prompt. If an attacker can convince a user to change their current directory into one controlled by the attacker, such as on a shared file system or extracted archive, fish will run arbitrary commands under the attacker's control. This problem has been fixed in fish 3.4.0. Note that running git in these directories, including using the git tab completion, remains a potential trigger for this issue. As a workaround, remove the fish_git_prompt function from the prompt.

The Tor Project reports:
TROVE-2022-002: The SafeSocks option for SOCKS4(a) is inverted leading to SOCKS4 going through
This is a report from hackerone:
We have classified this as medium considering that tor was not defending in-depth for dangerous SOCKS request and so any user relying on SafeSocks 1 to make sure they don't link DNS leak and their Tor traffic wasn't safe afterall for SOCKS4(a). Tor Browser doesn't use SafeSocks 1 and SOCKS4 so at least the likely vast majority of users are not affected.
lu4nx reports:
GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the ctags program.

When running Apache Cassandra with the following configuration: enable_user_defined_functions: true enable_scripted_user_defined_functions: true enable_user_defined_functions_threads: false it is possible for an attacker to execute arbitrary code on the host. The attacker would need to have enough permissions to create user defined functions in the cluster to be able to exploit this.
