"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0634 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-24575:
    libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid
    API, allowing to build Git functionality into your application. Using well-crafted inputs to
    `git_revparse_single` can cause the function to enter an infinite loop, potentially causing a Denial of
    Service attack in the calling application. The revparse function in `src/libgit2/revparse.c` uses a loop
    to parse the user-provided spec string. There is an edge-case during parsing that allows a bad actor to
    force the loop conditions to access arbitrary memory. Potentially, this could also leak memory if the
    extracted rev spec is reflected back to the attacker. As such, libgit2 versions before 1.4.0 are not
    affected. Users should upgrade to version 1.6.5 or 1.7.2.

    CVE-2024-24577:
    libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid
    API, allowing to build Git functionality into your application. Using well-crafted inputs to
    `git_index_add` can cause heap corruption that could be leveraged for arbitrary code execution. There is
    an issue in the `has_dir_name` function in `src/libgit2/index.c`, which frees an entry that should not be
    freed. The freed entry is later used and overwritten with potentially bad actor-controlled data leading to
    controlled heap corruption. Depending on the application that uses libgit2, this could lead to arbitrary
    code execution. This issue has been patched in version 1.6.5 and 1.7.2.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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