Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7626-1 advisory.

 Avi Halachmi discovered that Git incorrectly managed file modification constraints with Gitk. An attacker could possibly use this issue to create or write to arbitrary files on the system. (CVE-2025-27613)

 Avi Halachmi discovered that Git incorrectly handled arguments when invoking the Gitk utility. If a user were tricked into cloning a malicious Git repository, an attacker could possibly use this issue to run arbitrary commands. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
 (CVE-2025-27614)

 Johannes Sixt discovered that Git incorrectly managed file modification constraints with Git GUI. If a user were tricked into editing a file in a malicious Git repository, an attacker could possibly use this issue to create or write to arbitrary files on the system. (CVE-2025-46835)

 David Leadbeater discovered that Git incorrectly stripped CRLF characters when editing configuration files. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-48384)

 David Leadbeater discovered that Git incorrectly handled verification when fetching remote Git repositories. An attacker could possibly use this issue to perform protocol injection, leading to arbitrary code execution. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
 (CVE-2025-48385)

 David Leadbeater discovered that Git incorrectly handled memory with the wincred credential helper. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-48386)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
