curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service.

An unauthenticated attacker can cause a denial-of-service to the following products: Ivanti Connect Secure (ICS) in versions prior to 9.1R14.3, 9.1R15.2, 9.1R16.2, and 22.2R4, Ivanti Policy Secure (IPS) in versions prior to 9.1R17 and 22.3R1, and Ivanti Neurons for Zero-Trust Access in versions prior to 22.3R1.

A use-after-free in res_pjsip_pubsub.c in Sangoma Asterisk 16.28, 18.14, 19.6, and certified/18.9-cert2 may allow a remote authenticated attacker to crash Asterisk (denial of service) by performing activity on a subscription via a reliable transport at the same time that Asterisk is also performing activity on that subscription.

### Impact The package muhammara before 2.6.2, from 3.0.0 and before 3.3.0; all versions of package hummus are vulnerable to Denial of Service (DoS) when supplied with a maliciously crafted PDF file to be parsed. ### Patches It has been patched in 3.4.0 and has been backported to 2.6.2 There is no patch for hummus, currently ### Workarounds Do not process files from untrusted sources or update. Replace hummus with muhammara ### References https://github.com/julianhille/MuhammaraJS/pull/235 https://github.com/julianhille/MuhammaraJS/pull/238

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.

Ubuntu Security Notice 5759-1 - It was discovered that LibBPF incorrectly handled certain memory operations under certain circumstances. An attacker could possibly use this issue to cause LibBPF to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 22.10. It was discovered that LibBPF incorrectly handled certain memory operations under certain circumstances. An attacker could possibly use this issue to cause LibBPF to crash, resulting in a denial of service, or possibly execute arbitrary code.

Debian Linux Security Advisory 5294-1 - Jhead, a tool for manipulating EXIF data embedded in JPEG images, allowed attackers to execute arbitrary OS commands by placing them in a JPEG filename and then using the regeneration -rgt50, -autorot or -ce option. In addition a buffer overflow error in exif.c has been addressed which could lead to a denial of service (application crash).

Debian Linux Security Advisory 5293-1 - Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

Ubuntu Security Notice 5756-2 - Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a memory leak existed in the IPv6 implementation of the Linux kernel. A local attacker could use this to cause a denial of service.
