Ubuntu Linux has recently released updates to address security vulnerabilities in several software packages, including Protocol Buffers, DjVuLibre, Git, and YAML-LibYAML. The updates are aimed at enhancing the security and stability of the system, particularly for specific versions of Ubuntu.
1. Protocol Buffers (USN-7629-1):
- A vulnerability was found that could allow specially crafted input to crash the system, affecting Ubuntu 25.04, 24.04 LTS, and 22.04 LTS. Specific updates for the `libprotobuf-java` and `python3-protobuf` packages have been made available to fix these issues.
2. DjVuLibre (USN-7631-1):
- This vulnerability could lead to crashes or the execution of arbitrary code when processing specially crafted DjVu files, impacting the same Ubuntu versions. The necessary updates for `libdjvulibre21` have been provided.
3. Git (USN-7626-2):
- An update introduced a regression that affected Git's GUI tools (gitk and git-gui), which could lead to improper file management and potential security risks. A rollback of specific patches was issued to address these issues, with updates available for older Ubuntu versions as well.
4. YAML-LibYAML (USN-7632-1):
- A vulnerability in this library could allow attackers to overwrite arbitrary files. Updates are available for Ubuntu 24.04 LTS and 22.04 LTS to mitigate this risk.
For each of these vulnerabilities, users are advised to perform a standard system update to install the latest package versions and ensure their systems are secure. References to the specific vulnerabilities and package information are provided for further details.
