][1251727] High CVE-2021-37973 : Use after free in Portals. Reported by Clement Lecigne from Google TAG, with technical assistance from Sergei Glazunov and Mark Brand from Google Project Zero on 2021-09-21
Google is aware that an exploit for CVE-2021-37973 exists in the wild.
Tim Wojtulewicz of Corelight reports:
Paths from log stream make it into system() unchecked, potentially leading to commands being run on the system unintentionally. This requires either bad scripting or a malicious package to be installed, and is considered low severity.
Fix potential unbounded state growth in the PIA analyzer when receiving a connection with either a large number of zero-length packets, or one which continues ack-ing unseen segments. It is possible to run Zeek out of memory in these instances and cause it to crash. Due to the possibility of this happening with packets received from the network, this is a potential DoS vulnerability.

libssh security advisories:
The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called `secret_hash` and and the other `session_id`. Initially, both of them are the same, but after key re-exchange, previous `session_id` is kept and used as an input to new `secret_hash`.
Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating `secret_hash` of different size than the `session_id` has.
This becomes an issue when the `session_id` memory is zeroized or when it is used again during second key re-exchange.

Kenny Levinsen reports:
seatd-launch used execlp, which reads the PATH environment variable to search for the requested executable, to execute seatd. This meant that the caller could freely control what executable was loaded by adding a user-writable directory to PATH.
If seatd-launch had the SUID bit set, this could be used by a malicious user with the ability to execute seatd-launch to mount a privilege escalation attack to the owner of seatd-launch, which is likely root.

Matrix developers report:
Today we are disclosing a critical security issue affecting multiple Matrix clients and libraries including Element (Web/Desktop/Android), FluffyChat, Nheko, Cinny, and SchildiChat.
Specifically, in certain circumstances it may be possible to trick vulnerable clients into disclosing encryption keys for messages previously sent by that client to user accounts later compromised by an attacker.
Exploiting this vulnerability to read encrypted messages requires gaining control over the recipient’s account. This requires either compromising their credentials directly or compromising their homeserver.
Hashicorp reports:
HashiCorp Consul Raft RPC layer allows non-server agents with a valid certificate signed by the same CA to access server-only functionality, enabling privilege escalation.
The Go project reports:
An oversight in the previous fix still allows for an OOM panic when the indicated directory size in the archive header is so large that subtracting it from the archive size overflows a uint64, effectively bypassing the check that the number of files in the archive is reasonable.

bpo-43124: Made the internal putcmd function in smtplib sanitize input for presence of \r and \n characters to avoid (unlikely) command injection.
bpo-36384: ipaddress module no longer accepts any leading zeros in IPv4 address strings. Leading zeros are ambiguous and interpreted as octal notation by some libraries. For example the legacy function socket.inet_aton() treats leading zeros as octal notation. glibc implementation of modern inet_pton() does not accept any leading zeros. For a while the ipaddress module used to accept ambiguous leading zeros.
Version 5.9_2 contains security fix for PPPoE servers. Insufficient validation of incoming PPPoE Discovery request specially crafted by unauthenticated user might lead to unexpected termination of the process. The problem affects mpd versions since 5.0.

Cyrus IMAP 3.4.2 Release Notes states:
Fixed CVE-2021-33582: Certain user inputs are used as hash table keys during processing. A poorly chosen string hashing algorithm meant that the user could control which bucket their data was stored in, allowing a malicious user to direct many inputs to a single bucket. Each subsequent insertion to the same bucket requires a strcmp of every other entry in it. At tens of thousands of entries, each new insertion could keep the CPU busy in a strcmp loop for minutes. The string hashing algorithm has been replaced with a better one, and now also uses a random seed per hash table, so malicious inputs cannot be precomputed.

Problem:
In certain circumstances, fetchmail 6.4.21 and older would not encrypt the session using STARTTLS/STLS, and might not have cleared session state across the TLS negotiation.
The passive mode in FTP communication allows an out of boundary read while libfetch uses strtol to parse the relevant numbers into address bytes. It does not check if the line ends prematurely. If it does, the for-loop condition checks for *p == '\0' one byte too late because p++ was already performed.
The connection buffer size can be controlled by a malicious FTP server because the size is increased until a newline is encountered (or no more characters are read). This also allows to move the buffer into more interesting areas within the address space, potentially parsing relevant numbers for the attacker. Since these bytes become available to the server in form of a new TCP connection to a constructed port number or even part of the IPv6 address this is a potential information leak.
The ggatec(8) daemon does not validate the size of a response before writing it to a fixed-sized buffer. This allows to overwrite the stack of ggatec(8).
A malicious ggated(8) or an attacker in a priviledged network position can overwrite the stack with crafted content and potentially execute arbitrary code.
Certain VirtIO-based device models failed to handle errors when fetching I/O descriptors. Such errors could be triggered by a malicious guest. As a result, the device model code could be tricked into operating on uninitialized I/O vectors, leading to memory corruption.
A malicious guest may be able to crash the bhyve process. It may be possible to exploit the memory corruption bugs to achieve arbitrary code execution in the bhyve process.

The PostgreSQL Project reports:
A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.
Debian reports:
xtrlock did not block multitouch events so an attacker could still input and thus control various programs such as Chromium, etc. via so-called "multitouch" events including pan scrolling, "pinch and zoom" or even being able to provide regular mouse clicks by depressing the touchpad once and then clicking with a secondary finger.

Parameter values could be sourced from user provided data (eg user names) as well as configuration data provided by an administrator. In limited circumstances it was possible for users to authenticate using variations of their user name and/or to bypass some of the protection provided by the LockOut Realm.
rbeaudry reports:
A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This meant that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users were able to trigger non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a DoS.
Applications that do not use non-blocking I/O are not exposed to this vulnerability. This issue affects Apache Tomcat 10.0.3 to 10.0.4; 9.0.44; 8.5.64.
Matthias Andree reports:
When a log message exceeds c. 2 kByte in size, for instance, with very long header contents, and depending on verbosity option, fetchmail can crash or misreport each first log message that requires a buffer reallocation.
Huang Zhw reports:
On 32-bit versions, Redis BITFIELD command is vulnerable to integer overflow that can potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code execution. The vulnerability involves constructing specially crafted bit commands which overflow the bit offset.
This problem only affects 32-bit versions of Redis.

Roger Light reports:
If an authenticated client connected with MQTT v5 sent a malformed CONNACK message to the broker a NULL pointer dereference occurred, most likely resulting in a segfault.
(Note: a CVE is referenced in the github commit but it appears to be for a python-bleach vulnerability so it is not included here.)
pjsip reports:
There are a couple of issues found in the SSL socket:
- A race condition between callback and destroy, due to the accepted socket having no group lock.
- SSL socket parent/listener may get destroyed during handshake.
The Asterisk project reports:
Depending on the timing, it's possible for Asterisk to crash when using a TLS connection if the underlying socket parent/listener gets destroyed during the handshake.
The Asterisk project reports:
If the IAX2 channel driver receives a packet that contains an unsupported media format it can cause a crash to occur in Asterisk.
The Asterisk project reports:
When Asterisk receives a re-INVITE without SDP after having sent a BYE request a crash will occur. This occurs due to the Asterisk channel no longer being present while code assumes it is.

The Go project reports:
crypto/tls clients can panic when provided a certificate of the wrong type for the negotiated parameters. net/http clients performing HTTPS requests are also affected. The panic can be triggered by an attacker in a privileged network position without access to the server certificate's private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify. Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0–1.2 cipher suites without ECDHE), as well as TLS 1.3-only clients, are unaffected.

Arbitrary file read via design feature
Exiv2 teams reports:
Multiple vulnerabilities covering buffer overflows, out-of-bounds, read of uninitialized memory and denial of serivce. The heap overflow is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick the victim into running Exiv2 on a crafted image file. The read of uninitialized memory is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to leak a few bytes of stack memory, if they can trick the victim into running Exiv2 on a crafted image file.

Session fixation vulnerability
Jonathon Knudsen of Synopsys Cybersecurity Research Center reports:
All versions prior to 3.8.16 are prone to a denial of service vulnerability due to improper input validation in AMQP 1.0 client connection endpoint. A malicious client can exploit the vulnerability by sending malicious AMQP messages to the target RabbitMQ instance having the AMQP 1.0 plugin enabled.
alanxz reports:
When parsing a frame header, validate that the frame_size is less than or equal to INT32_MAX. Given frame_max is limited between 0 and INT32_MAX in amqp_login and friends, this does not change the API. This prevents a potential buffer overflow when a malicious client sends a frame_size that is close to UINT32_MAX, in which causes an overflow when computing state->target_size resulting in a small value there. A buffer is then allocated with the small amount, then memcopy copies the frame_size writing to memory beyond the end of the buffer.
Puppet reports:
Fixed an issue where someone with the ability to query PuppetDB could arbitrarily write, update, or delete data CVE-2021-27021 PDB-5138.

Dovecot team reports reports:
Sieve interpreter is not protected against abusive scripts that claim excessive resource usage. Fixed by limiting the user CPU time per single script execution and cumulatively over several script runs within a configurable timeout period. Sufficiently large CPU time usage is summed in the Sieve script binary and execution is blocked when the sum exceeds the limit within that time. The block is lifted when the script is updated after the resource usage times out.
Dovecot team reports:
CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in JWT tokens. This may be used to supply attacker controlled keys to validate tokens in some configurations. This requires attacker to be able to write files to local disk.
CVE-2021-33515: On-path attacker could inject plaintext commands before STARTTLS negotiation that would be executed after STARTTLS finished with the client. Only the SMTP submission service is affected.

Drupal Security team reports:
Drupal core's sanitization API fails to properly filter cross-site scripting under certain circumstances. Not all sites and users are affected, but configuration changes to prevent the exploit might be impractical and will vary between sites. Therefore, we recommend all sites update to this release as soon as possible.
Cedric Buissart reports:
The function
polkit_system_bus_name_get_creds_syncis used to get the uid and pid of the process requesting the action. It does this by sending the unique bus name of the requesting process, which is typically something like ":1.96", todbus-daemon. These unique names are assigned and managed bydbus-daemonand cannot be forged, so this is a good way to check the privileges of the requesting process.The vulnerability happens when the requesting process disconnects from
dbus-daemonjust before the call topolkit_system_bus_name_get_creds_syncstarts. In this scenario, the unique bus name is no longer valid, sodbus-daemonsends back an error reply. This error case is handled inpolkit_system_bus_name_get_creds_syncby setting the value of theerrorparameter, but it still returnsTRUE, rather thanFALSE. This behavior means that all callers ofpolkit_system_bus_name_get_creds_syncneed to carefully check whether an error was set. If the calling function forgets to check for errors then it will think that the uid of the requesting process is 0 (because theAsyncGetBusNameCredsDatastruct is zero initialized). In other words, it will think that the action was requested by a root process, and will therefore allow it.
sogo.nu reports:
SOGo was not validating the signatures of any SAML assertions it received.
This means any actor with network access to the deployment could impersonate
users when SAML was the authentication method.
The :class:`~urllib.request.AbstractBasicAuthHandler` class of the :mod:`urllib.request` module uses an inefficient regular expression which can be exploited by an attacker to cause a denial of service
entrouvert reports:
When AuthnResponse messages are not signed (which is permitted by the specifiation), all assertion's signatures should be checked, but currently after the first signed assertion is checked all following assertions are accepted without checking their signature, and the last one is considered the main assertion.
The Go project reports:
The SetString and UnmarshalText methods of math/big.Rat may cause a panic or an unrecoverable fatal error if passed inputs with very large exponents.
ReverseProxy in net/http/httputil could be made to forward certain hop-by-hop headers, including Connection. In case the target of the ReverseProxy was itself a reverse proxy, this would let an attacker drop arbitrary headers, including those set by the ReverseProxy.Director.
The LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in net, and their respective methods on the Resolver type may return arbitrary values retrieved from DNS which do not follow the established RFC 1035 rules for domain names. If these names are used without further sanitization, for instance unsafely included in HTML, they may allow for injection of unexpected content. Note that LookupTXT may still return arbitrary values that could require sanitization before further use.
The NewReader and OpenReader functions in archive/zip can cause a panic or an unrecoverable fatal error when reading an archive that claims to contain a large number of files, regardless of its actual size.
Sviatoslav Sydorenko reports:
Open redirect vulnerability — a maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website.

Tim Wojtulewicz of Corelight reports:
Fix potential Undefined Behavior in decode_netbios_name() and decode_netbios_name_type() BIFs. The latter has a possibility of a remote heap-buffer-overread, making this a potential DoS vulnerability.
Add some extra length checking when parsing mobile ipv6 packets. Due to the possibility of reading invalid headers from remote sources, this is a potential DoS vulnerability.
A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.

Redis development team reports:
An integer overflow bug in Redis version 6.0 or newer can be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution. This is a result of an incomplete fix by CVE-2021-29477.
The X.org project reports:
XLookupColor() and other X libraries function lack proper validation of the length of their string parameters. If those parameters can be controlled by an external application (for instance a color name that can be emitted via a terminal control sequence) it can lead to the emission of extra X protocol requests to the X server.
Prometheus reports:
Prometheus is an open-source monitoring system and time series database. In 2.23.0, Prometheus changed its default UI to the New ui. To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint. If a user visits a prometheus server with a specially crafted address, they can be redirected to an arbitrary URL. The issue was patched in the 2.26.1 and 2.27.1 releases. In 2.28.0, the /new endpoint will be removed completely. The workaround is to disable access to /new via a reverse proxy in front of Prometheus.
Tobias Stoeckmann reports:
The libXcursor fix for CVE-2013-2003 has never been imported into wayland, leaving it vulnerable to it.
libradius did not perform sufficient validation of received messages.
rad_get_attr(3) did not verify that the attribute length is valid before subtracting the length of the Type and Length fields. As a result, it could return success while also providing a bogus length of SIZE_T_MAX - 2 for the Value field.
When processing attributes to find an optional authenticator, is_valid_response() failed to verify that each attribute length is non-zero and could thus enter an infinite loop.
A server may use libradius(3) to process messages from RADIUS clients. In this case, a malicious client could trigger a denial-of-service in the server. A client using libradius(3) to process messages from a server is susceptible to the same problem.
The impact of the rad_get_attr(3) bug depends on how the returned length is validated and used by the consumer. It is possible that libradius(3) applications will crash or enter an infinite loop when calling rad_get_attr(3) on untrusted RADIUS messages.
The FreeBSD kernel enables SMAP during boot when the CPU reports that the SMAP capability is present. Subroutines such as copyin() and copyout() are responsible for disabling SMAP around the sections of code that perform user memory accesses.
Such subroutines must handle page faults triggered when user memory is not mapped. The kernel's page fault handler checks the validity of the fault, and if it is indeed valid it will map a page and resume copying. If the fault is invalid, the fault handler returns control to a trampoline which aborts the operation and causes an error to be returned. In this second scenario, a bug in the implementation of SMAP support meant that SMAP would remain disabled until the thread returns to user mode.
This bug may be used to bypass the protections provided by SMAP for the duration of a system call. It could thus be combined with other kernel bugs to craft an exploit.

Google's oss-fuzz project reports:
Denial-of-Service on CURVE/ZAP-protected servers by unauthenticated clients. If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them.
Fang-Pen Lin reports:
A remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations.
NGINX team reports:
1-byte memory overwrite might occur during DNS server response processing if the "resolver" directive was used, allowing an attacker who is able to forge UDP packets from the DNS server to cause worker process crash or, potentially, arbitrary code execution.
PG Partition Manager reports:
In the pg_partman (aka PG Partition Manager) extension before 4.5.1 for PostgreSQL, arbitrary code execution can be achieved via SECURITY DEFINER functions because an explicit search_path is not set.
Kurt Seifried reports:
So here are the CVE's for the two big ones, libxml2 and expat. Both are affected by the expansion of internal entities (which can be used to consume resources) and external entities (which can cause a denial of service against other services, be used to port scan, etc.).
A billion laughs attack is a type of denial-of-service attack which is aimed at parsers of XML documents.
Daniel Veillard reports:
A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing protection mechanisms and leading to denial of service.
The PostgreSQL project reports:
Memory disclosure in INSERT ... ON CONFLICT ... DO UPDATE
Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted table, an attacker can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will. A user lacking the CREATE and TEMPORARY privileges on all databases and the CREATE privilege on all schemas cannot use this attack at will..
Buffer overrun from integer overflow in array subscripting calculations
While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory.
The PostgreSQL project reports:
Using an UPDATE ... RETURNING on a purpose-crafted partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will. A user lacking the CREATE and TEMPORARY privileges on all databases and the CREATE privilege on all schemas typically cannot use this attack at will.

Python reports:
bpo-43434: Creating a sqlite3.Connection object now also produces a sqlite3.connect auditing event. Previously this event was only produced by sqlite3.connect() calls. Patch by Erlend E. Aasland.
bpo-43882: The presence of newline or tab characters in parts of a URL could allow some forms of attacks.Following the controlling specification for URLs defined by WHATWG urllib.parse() now removes A SCII newlines and tabs from URLs, preventing such attacks.
bpo-43472: Ensures interpreter-level audit hooks receive the cpython. PyInterpreterState_New event when called through the _xxsubinterpreters module.
bpo-36384: ipaddress module no longer accepts any leading zeros in IPv4 address strings. Leading zeros are ambiguous and interpreted as octal notation by some libraries. For example the legacy function socket.inet_aton() treats leading zeros as octal notatation. glibc implementation of modern inet_pton() does not accept any leading zeros. For a while the ipaddress module used to accept ambiguous leading zeros.
bpo-43075: Fix Regular Expression Denial of Service (ReDoS) vulnerability in urllib.request.AbstractBasicAuthHandler. The ReDoS-vulnerable regex has quadratic worst-case complexity and it allows cause a denial of service when identifying crafted invalid RFCs. This ReDoS issue is on the client side and needs remote attackers to control the HTTP server.
bpo-42800: Audit hooks are now fired for frame.f_code, traceback.tb_frame, and generator code/frame attribute access.
Redis project reports:
- Vulnerability in the STRALGO LCS command
- An integer overflow bug in Redis version 6.0 or newer could be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution.
- Vulnerability in the COPY command for large intsets
- An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration value, creating a large set key that consists of integer values and using the COPY command to duplicate it. The integer overflow bug exists in all versions of Redis starting with 2.6, where it could result with a corrupted RDB or DUMP payload, but not exploited through COPY (which did not exist before 6.2).
Alexandr Savca reports:
RDoc used to call Kernel#open to open a local file. If a Ruby project has a file whose name starts with | and ends with tags, the command following the pipe character is executed. A malicious Ruby project could exploit it to run an arbitrary command execution against a user who attempts to run rdoc command.

Community reports:
Fix Code Injection vulnerability in CarrierWave::RMagick
Fix SSRF vulnerability in the remote file download feature
Earlier versions of Sympa require a parameter named cookie in sympa.conf configuration file.
This parameter was used to make some identifiers generated by the system unpredictable. For example, it was used as following:
- To be used as a salt to encrypt passwords stored in the database by the RC4 symmetric key algorithm.
Note that RC4 is no longer considered secure enough and is not supported in the current version of Sympa.
- To prevent attackers from sending crafted messages to achieve XSS and so on in message archives.
There were the following problems with the use of this parameter.
- This parameter, for its purpose, should be different for each installation, and once set, it cannot be changed. As a result, some sites have been operating without setting this parameter. This completely invalidates the security measures described above.
- Even if this parameter is properly set, it may be considered not being strong enough against brute force attacks.

Shibboleth project reports:
Session recovery feature contains a null pointer deference.
The cookie-based session recovery feature added in V3.0 contains a flaw that is exploitable on systems *not* using the feature if a specially crafted cookie is supplied.
This manifests as a crash in the shibd daemon/service process.
Because it is very simple to trigger this condition remotely, it results in a potential denial of service condition exploitable by a remote, unauthenticated attacker.
Jon Siwek of Corelight reports:
Fix null-pointer dereference when encountering an invalid enum name in a config/input file that tries to read it into a set[enum]. For those that have such an input feed whose contents may come from external/remote sources, this is a potential DoS vulnerability.

The Apache Openofffice project reports:
The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink.
The Apache Maven project reports:
We received a report from Jonathan Leitschuh about a vulnerability of custom repositories in dependency POMs. We've split this up into three separate issues:
- Possible Man-In-The-Middle-Attack due to custom repositories using HTTP. More and more repositories use HTTPS nowadays, but this hasn't always been the case. This means that Maven Central contains POMs with custom repositories that refer to a URL over HTTP. This makes downloads via such repository a target for a MITM attack. At the same time, developers are probably not aware that for some downloads an insecure URL is being used. Because uploaded POMs to Maven Central are immutable, a change for Maven was required. To solve this, we extended the mirror configuration with blocked parameter, and we added a new external:http:* mirror selector (like existing external:*), meaning "any external URL using HTTP". The decision was made to block such external HTTP repositories by default: this is done by providing a mirror in the conf/settings.xml blocking insecure HTTP external URLs.
- Possible Domain Hijacking due to custom repositories using abandoned domains Sonatype has analyzed which domains were abandoned and has claimed these domains.
- Possible hijacking of downloads by redirecting to custom repositories This one was the hardest to analyze and explain. The short story is: you're safe, dependencies are only downloaded from repositories within their context. So there are two main questions: what is the context and what is the order? The order is described on the Repository Order page. The first group of repositories are defined in the settings.xml (both user and global). The second group of repositories are based on inheritence, with ultimately the super POM containing the URL to Maven Central. The third group is the most complex one but is important to understand the term context: repositories from the effective POMs from the dependency path to the artifact. So if a dependency was defined by another dependency or by a Maven project, it will also include their repositories. In the end this is not a bug, but a design feature.

Daniel Stenberg reports:
Enabled by default, libcurl supports the use of TLS 1.3 session tickets to resume previous TLS sessions to speed up subsequent TLS handshakes.
When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. The reason for this confusion is the modified sequence from TLS 1.2 when the session ids would provided only during the TLS handshake, while in TLS 1.3 it happens post hand-shake and the code was not updated to take that changed behavior into account.
When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed.
This flaw can allow a malicious HTTPS proxy to MITM the traffic. Such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check.
Daniel Stenberg reports:
libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
libcurl automatically sets the Referer: HTTP request header field in outgoing HTTP requests if the CURLOPT_AUTOREFERER option is set. With the curl tool, it is enabled with --referer ";auto".

Due to a race condition between lookup of ".." and remounting a filesystem, a process running inside a jail might access filesystem hierarchy outside of jail.
A process with superuser privileges running inside a jail configured with the allow.mount permission (not enabled by default) could change the root directory outside of the jail, and thus gain full read and write access to all files and directories in the system.
An unprivileged process can configure an accept filter on a listening socket. This is done using the setsockopt(2) system call. The process supplies the name of the accept filter which is to be attached to the socket, as well as a string containing filter-specific information.
If the filter implements the accf_create callback, the socket option handler attempts to preserve the process-supplied argument string. A bug in the socket option handler caused this string to be freed prematurely, leaving a dangling pointer. Additional operations on the socket can turn this into a double free or a use-after-free.
The bug may be exploited to trigger local privilege escalation or kernel memory disclosure.
A particular case of memory sharing is mishandled in the virtual memory system. It is possible and legal to establish a relationship where multiple descendant processes share a mapping which shadows memory of an ancestor process. In this scenario, when one process modifies memory through such a mapping, the copy-on-write logic fails to invalidate other mappings of the source page. These stale mappings may remain even after the mapped pages have been reused for another purpose.
An unprivileged local user process can maintain a mapping of a page after it is freed, allowing that process to read private data belonging to other processes or the kernel.

Niels Möller reports:
I've prepared a new bug-fix release of Nettle, a low-level cryptographics library, to fix a serious bug in the function to verify ECDSA signatures. Implications include an assertion failure, which could be used for denial-of-service, when verifying signatures on the secp_224r1 and secp521_r1 curves.
Even when no assert is triggered in ecdsa_verify, ECC point multiplication may get invalid intermediate values as input, and produce incorrect results. [...] It appears difficult to construct an alleged signature that makes the function misbehave in such a way that an invalid signature is accepted as valid, but such attacks can't be ruled out without further analysis.
The OpenSSL project reports:
High: CA certificate check bypass with X509_V_FLAG_X509_STRICT (CVE-2021-3450)
The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default.High: NULL pointer deref in signature_algorithms processing (CVE-2021-3449)
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack.

OpenBSD Project reports:
ssh-agent(1): fixed a double-free memory corruption that was introduced in OpenSSH 8.2 . We treat all such memory faults as potentially exploitable. This bug could be reached by an attacker with access to the agent socket.
On modern operating systems where the OS can provide information about the user identity connected to a socket, OpenSSH ssh-agent and sshd limit agent socket access only to the originating user and root. Additional mitigation may be afforded by the system's malloc(3)/free(3) implementation, if it detects double-free conditions.
The most likely scenario for exploitation is a user forwarding an agent either to an account shared with a malicious user or to a host with an attacker holding root access.

minio developer report:
This is a security issue because it enables MITM modification of request bodies that are meant to have integrity guaranteed by chunk signatures.
In a PUT request using aws-chunked encoding, MinIO ordinarily verifies signatures at the end of a chunk. This check can be skipped if the client sends a false chunk size that is much greater than the actual data sent: the server accepts and completes the request without ever reaching the end of the chunk + thereby without ever checking the chunk signature.

Node.js reports:
HTTP2 'unknownProtocol' cause Denial of Service by resource exhaustion (Critical) (CVE-2021-22883)
Affected Node.js versions are vulnerable to denial of service attacks when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.
DNS rebinding in --inspect (CVE-2021-22884)
Affected Node.js versions are vulnerable to a DNS rebinding attack when the whitelist includes "localhost6". When "localhost6" is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the "localhost6" domain. As long as the attacker uses the "localhost6" domain, they can still apply the attack described in CVE-2018-7160.

vault developers report:
Limited Unauthenticated License Read: We addressed a security vulnerability that allowed for the unauthenticated reading of Vault licenses from DR Secondaries.
Due to a race condition in the jail_remove(2) implementation, it may fail to kill some of the processes.
A process running inside a jail can avoid being killed during jail termination. If a jail is subsequently started with the same root path, a lingering jailed process may be able to exploit the window during which a devfs filesystem is mounted but the jail's devfs ruleset has not been applied, to access device nodes which are ordinarily inaccessible. If the process is privileged, it may be able to escape the jail and gain full access to the system.
Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation.
Unfortunately, when running in HVM/PVH mode, the FreeBSD backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery.
A malicious or buggy frontend driver may be able to cause resource leaks in the domain running the corresponding backend driver.
When a process, such as jexec(8) or killall(1), calls jail_attach(2) to enter a jail, the jailed root can attach to it using ptrace(2) before the current working directory is changed.
A process with superuser privileges running inside a jail could change the root directory outside of the jail, thereby gaining full read and writing access to all files and directories in the system.
A regression in the login.access(5) rule processor has the effect of causing rules to fail to match even when they should not. This means that rules denying access may be ignored.
The configuration in login.access(5) may not be applied, permitting login access to users even when the system is configured to deny it.
Redis Development team reports:
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption.

The Asterisk project reports:
Given a scenario where an outgoing call is placed from Asterisk to a remote SIP server it is possible for a crash to occur.
The Asterisk project reports:
Due to a signedness comparison mismatch, an authenticated WebRTC client could cause a stack overflow and Asterisk crash by sending multiple hold/unhold requests in quick succession.
The Asterisk project reports:
An unauthenticated remote attacker could replay SRTP packets which could cause an Asterisk instance configured without strict RTP validation to tear down calls prematurely.
The Asterisk project reports:
When re-negotiating for T.38 if the initial remote response was delayed just enough Asterisk would send both audio and T.38 in the SDP. If this happened, and the remote responded with a declined T.38 stream then Asterisk would crash.
The Asterisk project reports:
If a registered user is tricked into dialing a malicious number that sends lots of 181 responses to Asterisk, each one will cause a 181 to be sent back to the original caller with an increasing number of entries in the "Supported" header. Eventually the number of entries in the header exceeds the size of the entry array and causes a crash.

The OpenSSL project reports:
Null pointer deref in X509_issuer_and_serial_hash() CVE-2021-23841
(Moderate) The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack.Integer overflow in CipherUpdate CVE-2021-23840
(Low) Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash.

Minio developers report:
Thanks to @phith0n from our community upon a code review, discovered an SSRF (Server Side Request Forgery) in our Browser API implementation. We have not observed this report/attack in the wild or reported elsewhere in the community at large.
All users are advised to upgrade ASAP.
The target application may have functionality for importing data from a URL, publishing data to a URL, or otherwise reading data from a URL that can be tampered with. The attacker modifies the calls to this functionality by supplying a completely different URL or by manipulating how URLs are built (path traversal etc.).
In a Server-Side Request Forgery (SSRF) attack, the attacker can abuse functionality on the server to read or update internal resources. The attacker can supply or modify a URL which the code running on the server will read or submit data, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like HTTP enabled databases, or perform post requests towards internal services which are not intended to be exposed.
Some OSes (including Linux, FreeBSD, and NetBSD) are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued.
As the queue is unbound, a guest may be able to trigger a OOM in the backend.
Several file systems were not properly initializing the d_off field of the dirent structures returned by VOP_READDIR. In particular, tmpfs(5), smbfs(5), autofs(5) and mqueuefs(5) were failing to do so. As a result, eight uninitialized kernel stack bytes may be leaked to userspace by these file systems. This problem is not present in FreeBSD 11.
Additionally, msdosfs(5) was failing to zero-fill a pair of padding fields in the dirent structure, resulting in a leak of three uninitialized bytes.
Kernel stack disclosures may leak sensitive information which could be used to compromise the security of the system.
The libpng project reports:
pngcheck versions 3.0.0 and earlier have a pair of buffer-overrun bugs related to the sPLT and PPLT chunks (the latter is a MNG-only chunk, but it gets noticed even in PNG files if the -s option is used). Both bugs are fixed in version 3.0.1, released on 24 January 2021. Again, while all known vulnerabilities are fixed in this version, the code is quite crufty, so it would be safest to assume there are still some problems hidden in there. As always, use at your own risk.
Todd C. Miller reports:
When invoked as sudoedit, the same set of command line options are now accepted as for sudo -e. The -H and -P options are now rejected for sudoedit and sudo -e which matches the sudo 1.7 behavior. This is part of the fix for CVE-2021-3156.
Fixed a potential buffer overflow when unescaping backslashes in the command's arguments. Normally, sudo escapes special characters when running a command via a shell (sudo -s or sudo -i). However, it was also possible to run sudoedit with the -s or -i flags in which case no escaping had actually been done, making a buffer overflow possible. This fixes CVE-2021-3156.

Michal Dardas from LogicalTrust reports:
The server in Chocolate Doom 3.0.0 and Crispy Doom 5.8.0 doesn't validate the user-controlled num_players value, leading to a buffer overflow. A malicious user can overwrite the server's stack.
Nokogiri reports:
In Nokogiri versions <= 1.11.0.rc3, XML Schemas parsed by Nokogiri::XML::Schema were trusted by default, allowing external resources to be accessed over the network, potentially enabling XXE or SSRF attacks.
Simon Kelley reports:
There are broadly two sets of problems. The first is subtle errors in dnsmasq's protections against the chronic weakness of the DNS protocol to cache-poisoning attacks; the Birthday attack, Kaminsky, etc.[...]
the second set of errors is a good old fashioned buffer overflow in dnsmasq's DNSSEC code. If DNSSEC validation is enabled, an installation is at risk.
The Go project reports:
The go command may execute arbitrary code at build time when cgo is in use on Windows. This may occur when running "go get", or any other command that builds code. Only users who build untrusted code (and don't execute it) are affected. In addition to Windows users, this can also affect Unix users who have "." listed explicitly in their PATH and are running "go get" or build commands outside of a module or with module mode disabled.
The P224() Curve implementation can in rare circumstances generate incorrect outputs, including returning invalid points from ScalarMult. The crypto/x509 and golang.org/x/crypto/ocsp (but not crypto/tls) packages support P-224 ECDSA keys, but they are not supported by publicly trusted certificate authorities. No other standard library or golang.org/x/crypto package supports or uses the P-224 curve.
cloud-init reports:
cloud-init release 20.4.1 is now available. This is a hotfix release, that contains a single patch to address a security issue in cloud-init 20.4.
Briefly, for users who provide more than one unique SSH key to cloud-init and have a shared AuthorizedKeysFile configured in sshd_config, cloud-init 20.4 started writing all of these keys to such a file, granting all such keys SSH access as root.
It's worth restating this implication: if you are using the default AuthorizedKeysFile setting in /etc/ssh/sshd_config, as most will be, then you are _not_ affected by this issue.
MoinMoin reports:
Security fix for CVE-2020-25074: fix remote code execution via cache action
Security fix for CVE-2020-15275: fix malicious SVG attachment causing stored XSS vulnerability
SO-AND-SO reports:
A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b.
Node.js reports:
use-after-free in TLSWrap (High) (CVE-2020-8265)
Affected Node.js versions are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits.
HTTP Request Smuggling in nodejs (Low) (CVE-2020-8287)
Affected versions of Node.js allow two copies of a header field in a http request. For example, two Transfer-Encoding header fields. In this case Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling.
OpenSSL - EDIPARTYNAME NULL pointer de-reference (CVE-2020-1971)
iThis is a vulnerability in OpenSSL which may be exploited through Node.js. You can read more about it in https://www.openssl.org/news/secadv/20201208.txt.
SO-AND-SO reports:
Ability to steal a user's API access token through GitLab Pages
The wavpack project reports:
src/pack_utils.c - issue #91: fix integer overflows resulting in buffer overruns (CVE-2020-35738) - sanitize configuration parameters better (improves clarity and aids debugging)

phpmyfaq developers report:
phpMyFAQ does not implement sufficient checks to avoid XSS injection for displaying tags.
Todd C. Miller reports:
A potential information leak in sudoedit that could be used to test for the existence of directories not normally accessible to the user in certain circumstances. When creating a new file, sudoedit checks to make sure the parent directory of the new file exists before running the editor. However, a race condition exists if the invoking user can replace (or create) the parent directory. If a symbolic link is created in place of the parent directory, sudoedit will run the editor as long as the target of the link exists.If the target of the link does not exist, an error message will be displayed. The race condition can be used to test for the existence of an arbitrary directory. However, it _cannot_ be used to write to an arbitrary location.
CairoSVG security advisories:
When processing SVG files, the python package CairoSVG uses two regular expressions which are vulnerable to Regular Expression Denial of Service (REDoS).
If an attacker provides a malicious SVG, it can make cairosvg get stuck processing the file for a very long time.
Gitlab reports:
Ability to steal a user's API access token through GitLab Pages
Prometheus denial of service via HTTP request with custom method
Unauthorized user is able to access private repository information under specific conditions
Regular expression denial of service in NuGet API
Regular expression denial of service in package uploads

Aki Tuomi reports:
When imap hibernation is active, an attacker can cause Dovecot to discover file system directory structure and access other users' emails using specially crafted command. The attacker must have valid credentials to access the mail server.
Mail delivery / parsing crashed when the 10 000th MIME part was message/rfc822 (or if parent was multipart/digest). This happened due to earlier MIME parsing changes for CVE-2020-12100.
