"The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1737153672 advisory.

  - 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, repositories with submodules can be crafted in a way that exploits a bug in Git whereby it can be
    fooled into writing files not into the submodule's worktree but into a `.git/` directory. This allows
    writing a hook that will be executed while the clone operation is still running, giving the user no
    opportunity to inspect the code that is being executed. 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. If symbolic link support is disabled in Git (e.g. via
    `git config --global core.symlinks false`), the described attack won't work. As always, it is best to
    avoid cloning repositories from untrusted sources. (CVE-2024-32002)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
