Ubuntu Linux has recently released a series of updates addressing critical security vulnerabilities across various software components, including Ruby, the Linux Kernel, FIS-GT.M, Apache HTTP Server, Vim, and GNU Binutils. These updates aim to enhance system security and stability by fixing issues that could be exploited by attackers.
1. Ruby Vulnerabilities ([USN-7418-1]):
- Affected Versions: Ruby 2.7, 3.0, 3.2, and 3.3.
- Issues include improper XML parsing, memory consumption in IMAP response parsing, and flaws in cookie and URI handling that could lead to denial of service or credential leakage.
2. Linux Kernel Vulnerabilities:
- NVIDIA Tegra IGX ([USN-7406-6]): Multiple vulnerabilities affecting GPU drivers, SMB, and networking subsystems discovered.
- General Linux Kernel ([USN-7402-4], [USN-7420-1], and others): Numerous vulnerabilities affecting various subsystems across different versions, including Azure and NVIDIA drivers.
3. FIS-GT.M Vulnerabilities ([USN-7422-1]):
- Issues lead to potential crashes and denial of service due to improper memory handling and input validation.
4. Apache HTTP Server Regression ([USN-6885-4]):
- A regression caused by a previous patch resulted in incorrect handling of certain substitutions, requiring updates to restore intended functionality.
5. Vim Vulnerabilities ([USN-7419-1]):
- Issues that could cause crashes from specially crafted inputs were identified, affecting multiple Ubuntu versions.
6. GNU Binutils Vulnerabilities ([USN-7423-1]):
- Problems related to incorrect input handling that could lead to crashes or arbitrary code execution were reported.
