Google: dev-vcs/git: security update to 18244.85.17

high Tenable Cloud Security Plugin ID 451865

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Git is a revision control system. Prior to versions 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2, and
2.39.4, when cloning a local source repository that contains symlinks via the filesystem, Git may create
hardlinks to arbitrary user-readable files on the same filesystem as the target repository in the
`objects/` directory. Cloning a local repository over the filesystem may creating hardlinks to arbitrary
user-owned files on the same filesystem in the target Git repository's `objects/` directory. When cloning
a repository over the filesystem (without explicitly specifying the `file://` protocol or `--no-local`),
the optimizations for local cloning will be used, which include attempting to hard link the object files
instead of copying them. While the code includes checks against symbolic links in the source repository,
which were added during the fix for CVE-2022-39253, these checks can still be raced because the hard link
operation ultimately follows symlinks. If the object on the filesystem appears as a file during the check,
and then a symlink during the operation, this will allow the adversary to bypass the check and create
hardlinks in the destination objects directory to arbitrary, user-readable files. The problem has been
patched in versions 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2, and 2.39.4. (CVE-2024-32021)

Solution
