patch available.

  - 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. When cloning a repository Git knows to
    optionally fetch a bundle advertised by the remote server, which allows the server-side to offload parts
    of the clone to a CDN. The Git client does not perform sufficient validation of the advertised bundles,
    which allows the remote side to perform protocol injection. This protocol injection can cause the client
    to write the fetched bundle to a location controlled by the adversary. The fetched content is fully
    controlled by the server, which can in the worst case lead to arbitrary code execution. The use of bundle
    URIs is not enabled by default and can be controlled by the bundle.heuristic config option. Some cases of
    the vulnerability require that the adversary is in control of where a repository will be cloned to. This
    either requires social engineering or a recursive clone with submodules. These cases can thus be avoided
    by disabling recursive clones. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3,
    v2.48.2, v2.49.1, and v2.50.1. (CVE-2025-48385)

Note that Nessus relies on the presence of the package as reported by the vendor.");
