The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-6494 advisory.

  • 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. (CVE-2023-41105)

  • 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-2007-4559)

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