"The remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:8353 advisory.

  - In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands
    discovered in the system mailcap file. This may allow attackers to inject shell commands into applications
    that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or
    arguments). The fix is also back-ported to 3.7, 3.8, 3.9 (CVE-2015-20107)

  - ** DISPUTED ** Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to
    no protection against multiple (/) at the beginning of URI path which may leads to information disclosure.
    NOTE: this is disputed by a third party because the http.server.html documentation page states Warning:
    http.server is not recommended for production. It only implements basic security checks. (CVE-2021-28861)

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