ALMALINUX9.2:CLSA-2025:1758040547 advisory.

  - Git is a fast, scalable, distributed revision control system with an unusually rich command set that
    provides both high-level operations and full access to internals. Git defines a line-based protocol that
    is used to exchange information between Git and Git credential helpers. Some ecosystems (most notably,
    .NET and node.js) interpret single Carriage Return characters as newlines, which renders the protections
    against CVE-2020-5260 incomplete for credential helpers that treat Carriage Returns in this way. This
    issue has been addressed in commit `b01b9b8` which is included in release versions v2.48.1, v2.47.2,
    v2.46.3, v2.45.3, v2.44.3, v2.43.6, v2.42.4, v2.41.3, and v2.40.4. Users are advised to upgrade. Users
    unable to upgrade should avoid cloning from untrusted URLs, especially recursive clones. (CVE-2024-52006)

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