Large loop in the Kafka dissector in Wireshark 3.6.0 allows denial of service via packet injection or crafted capture file
A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.
A flaw was found in util-linux's libmount. An issue related to parsing the /proc/self/mountinfo file allows an unprivileged user to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable directory.
A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of the attacker in its string form. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems.
Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be exploited. There is only a risk in conjunction with Java object deserialization within an application. In such situations, it allows attackers to erase contents of arbitrary files, make network connections, or possibly run arbitrary code (specifically, Function0 functions) via a gadget chain.
AMD. A memory corruption issue was addressed with improved input validation.
Impact Untrusted websocket connections can cause an out-of-memory (OOM) process abort in a client or a server. The root cause of the issue is during dataframe parsing. Affected versions would allocate a buffer based on the declared dataframe size, which may come from an untrusted source. When Vec::withcapacity fails to allocate, the default Rust allocator will abort the current process, killing all threads. This affects only sync (non-Tokio) implementation. Async version also does not limit memory, but does not use withcapacity, so DoS can happen only when bytes for oversized dataframe or message actually got delivered by the attacker.
This is a security concern for you, if - your server application handles untrusted websocket connections - OR your client application connects to untrusted websocket servers
Patches The crashes are fixed in version 0.26.5 by imposing default dataframe size limits. Affected users are advised to update to this version.
Note that default memory limits are rather large (100MB dataframes and 200 MB messages), so they can still cause DoS in some environments (i.e. 32-bit). New API has been added to fine tune those limits for specific applications.
Workarounds
Migrate your project to another, maintained Websocket library like Tungstenite. Accept only trusted WebSocket traffic. Filter the WebSocket traffic though some kind of proxy that ensures sanity limits on messages. Handle process aborts gracefully and limit process memory using OS tools.

Adobe InDesign versions 16.4.2 (and earlier) and 17.3 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Nextcloud server is an open source personal cloud server. Affected versions of nextcloud server did not properly limit user display names which could allow a malicious users to overload the backing database and cause a denial of service. It is recommended that the Nextcloud Server is upgraded to 22.2.10, 23.0.7 or 24.0.3. There are no known workarounds for this issue.
Crash in the pcapng file parser in Wireshark 3.6.0 allows denial of service via crafted capture file
HarfBuzz 2.9.0 has an out-of-bounds write in hbbitsetinvertiblet::set (called from hbsparsesett<hbbitsetinvertiblet>::set and hbsetcopy).
In MediaWiki through 1.37, the Special:ImportFile URI (aka FileImporter) allows XSS, as demonstrated by the clientUrl parameter.
In MediaWiki through 1.37, Wikibase item descriptions allow XSS, which is triggered upon a visit to an action=info URL (aka a page-information sidebar).
In MediaWiki through 1.37, blocked IP addresses are allowed to edit EntitySchema items.
In MediaWiki through 1.37, XSS can occur in Wikibase because an external identifier property can have a URL format that includes a $1 formatter substitution marker, and the javascript: URL scheme (among others) can be used.
A Denial of Service vulnerability exits in Binaryen 103 due to an assertion abort in wasm::handleunreachable.

A stack-based buffer overflow in handlerequest function in DHT.c in toxcore 0.1.9 through 0.1.11 and 0.2.0 through 0.2.12 (caused by an improper length calculation during the handling of received network packets) allows remote attackers to crash the process or potentially execute arbitrary code via a network packet.
Teeworlds up to and including 0.7.5 is vulnerable to Buffer Overflow. A map parser does not validate mChannels value coming from a map file, leading to a buffer overflow. A malicious server may offer a specially crafted map that will overwrite client's stack causing denial of service or code execution.
SchedMD Slurm 21.08. before 21.08.4 has Incorrect Access Control. On sites using the new AccountingStoreFlags=jobscript and/or jobenv options, the access control rules in SlurmDBD may permit users to request job scripts and environment files to which they should not have access.
An issue was discovered in stb stbimage.h 1.33 through 2.27. The HDR loader parsed truncated end-of-file RLE scanlines as an infinite sequence of zero-length runs. An attacker could potentially have caused denial of service in applications using stbimage by submitting crafted HDR files.
An issue was discovered in stb stbimage.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stbimage, or read up to 1024 bytes of non-consecutive heap data without control over the read location.
The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.
The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow via a crafted certificate with an RSASSA-PSS signature. For example, this can be triggered by an unrelated self-signed CA certificate sent by an initiator. Remote code execution cannot occur.
An issue was discovered in Squid 5.0.6 through 5.1.x before 5.2. When validating an origin server or peer certificate, Squid may incorrectly classify certain certificates as trusted. This problem allows a remote server to obtain security trust well improperly. This indication of trust may be passed along to clients, allowing access to unsafe or hijacked services.
Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16.
In NetKit through 0.17, rcp.c in the rcp client allows remote rsh servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. This is similar to CVE-2018-20685.
PoD operations on misaligned GFNs T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). The implementation of some of these hypercalls for PoD does not enforce the base page frame number to be suitably aligned for the specified order, yet some code involved in PoD handling actually makes such an assumption. These operations are XENMEMdecreasereservation (CVE-2021-28704) and XENMEMpopulatephysmap (CVE-2021-28707), the latter usable only by domains controlling the guest, i.e. a de-privileged qemu or a stub domain. (Patch 1, combining the fix to both these two issues.) In addition handling of XENMEMdecreasereservation can also trigger a host crash when the specified page order is neither 4k nor 2M nor 1G (CVE-2021-28708, patch 2).
The thefuck (aka The Fuck) is app that corrects errors in previous console commands. The Fuck python package before 3.31 allows Path Traversal that leads to arbitrary file deletion via the undo archive operation feature.
