Gentoo Linux Security Advisory 202403-4 - A backdoor has been discovered in XZ utils that could lead to remote compromise of systems. Versions less than 5.6.0 are affected.

A use-after-free vulnerability exists in the Linux kernel netfilter: nf_tables component. This is a universal local privilege escalation proof of concept exploit working on Linux kernels between 5.14 and 6.6, including Debian, Ubuntu, and KernelCTF.

Debian Linux Security Advisory 5650-1 - Skyler Ferrante discovered that the wall tool from util-linux does not properly handle escape sequences from command line arguments. A local attacker can take advantage of this flaw for information disclosure.

Red Hat Security Advisory 2024-1576-03 - An update for the ruby:3.1 module is now available for Red Hat Enterprise Linux 9. Issues addressed include HTTP response splitting and denial of service vulnerabilities.

RedHat on Friday released an "urgent security alert" warning that two versions of a popular data compression library called XZ Utils (previously LZMA Utils) have been backdoored with malicious code designed to allow unauthorized remote access. The software supply chain compromise, tracked as CVE-2024-3094, has a CVSS score of 10.0, indicating maximum severity. It impacts XZ Utils

This Metasploit module exploits a buffer overflow at the administration interface (8080 or 4117) of WatchGuard Firebox and XTM appliances which is built from a cherrypy python backend sending XML-RPC requests to a C binary called wgagent using pre-authentication endpoint /agent/login. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2. Successful exploitation results in remote code execution as user nobody.

Debian Linux Security Advisory 5649-1 - Andres Freund discovered that the upstream source tarballs for xz-utils, the XZ-format compression utilities, are compromised and inject malicious code, at build time, into the resulting liblzma5 library.

Debian Linux Security Advisory 5648-1 - Security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

Ubuntu Security Notice 6707-4 - Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
