"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0293 advisory.

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

      CVE-2007-4559:
      Directory traversal vulnerability in the (1) extract and (2) extractall functions in the tarfile module
    in Python allows user-assisted remote attackers to overwrite arbitrary files via a .. (dot dot) sequence
    in filenames in a TAR archive, a related issue to CVE-2001-1267.

      CVE-2023-41105:
      An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to
    os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible
    cases in which an application would have rejected a filename for security reasons in Python 3.10.x or
    earlier, but that filename is no longer rejected in Python 3.11.x.

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.");
