Ubuntu Security Notice 6562-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. DoHyun Lee discovered that Firefox did not properly manage memory when used on systems with the Mesa VM driver. An attacker could potentially exploit this issue to execute arbitrary code.

Debian Linux Security Advisory 5593-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

FTPDMIN version 0.96 suffers from a denial of service vulnerability.

Ultra Mini HTTPd version 1.21 suffers from a denial of service vulnerability.

Plus: Apple shuts down a Flipper Zero Attack, Microsoft patches more than 30 vulnerabilities, and more critical updates for the last month of 2023.

### Impact Denial of Service, Applications that allow the use of the PBKDF2 algorithm. ### Patches A [patch](https://github.com/latchset/jwcrypto/commit/d2655d370586cb830e49acfb450f87598da60be8) is available that sets the maximum number of default rounds. ### Workarounds Applications that do not need to use PBKDF2 should simply specify the algorithms use and exclude it from the list. Applications that need to use the algorithm should upgrade to the new version that allows to set a maximum rounds number. ### Acknowledgement The issues was reported by Jingcheng Yang and Jianjun Chen from Sichuan University and Zhongguancun Lab

Debian Linux Security Advisory 5591-1 - Several vulnerabilities were discovered in libssh, a tiny C SSH library.

Debian Linux Security Advisory 5589-1 - Multiple vulnerabilities were discovered in Node.js, which could result in HTTP request smuggling, bypass of policy feature checks, denial of service or loading of incorrect ICU data.

hutool-core v5.8.23 was discovered to contain an infinite loop in the StrSplitter.splitByRegex function. This vulnerability allows attackers to cause a Denial of Service (DoS) via manipulation of the first two parameters.

### Impact A denial of service (DoS) vulnerability was discovered in go-git versions prior to `v5.11`. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in `go-git` clients. Applications using only the in-memory filesystem supported by `go-git` are not affected by this vulnerability. This is a `go-git` implementation issue and does not affect the upstream `git` cli. ### Patches Users running versions of `go-git` from `v4` and above are recommended to upgrade to `v5.11` in order to mitigate this vulnerability. ### Workarounds In cases where a bump to the latest version of `go-git` is not possible, we recommend limiting its use to only trust-worthy Git servers. ## Credit Thanks to Ionut Lalu for responsibly disclosing this vulnerability to us. ### References - [GHSA-mw99-9chc-xw7r](https://github.com/go-git/go-git/security/advisories/GHSA-mw99-9chc-xw7r)
