"The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2022-d1682fef04 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)

  - A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when
    using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for
    1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not
    affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)

  - ** 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.");
