"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the TSSA-2023:0205 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2023-38497:
      Cargo downloads the Rust project's dependencies and compiles the project. Cargo prior to version 0.72.2,
    bundled with Rust prior to version 1.71.1, did not respect the umask when extracting crate archives on
    UNIX-like systems. If the user downloaded a crate containing files writeable by any local user, another
    local user could exploit this to change the source code compiled and executed by the current user. To
    prevent existing cached extractions from being exploitable, the Cargo binary version 0.72.2 included in
    Rust 1.71.1 or later will purge caches generated by older Cargo versions automatically. As a workaround,
    configure one's system to prevent other local users from accessing the Cargo directory, usually located in
    ~/.cargo.

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

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