"The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1737156361 advisory.

  - Git is a revision control system. The Git project recommends to avoid working in untrusted repositories,
    and instead to clone it first with `git clone --no-local` to obtain a clean copy. Git has specific
    protections to make that a safe operation even with an untrusted source repository, but vulnerabilities
    allow those protections to be bypassed. In the context of cloning local repositories owned by other users,
    this vulnerability has been covered in CVE-2024-32004. But there are circumstances where the fixes for
    CVE-2024-32004 are not enough: For example, when obtaining a `.zip` file containing a full copy of a Git
    repository, it should not be trusted by default to be safe, as e.g. hooks could be configured to run
    within the context of that repository. 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. As a workaround, avoid using Git in repositories that have been
    obtained via archives from untrusted sources. (CVE-2024-32465)

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