"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2024:0430 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,
    classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to
    many system calls and libraries, as well as to various windowing systems.

    Security Fix(es):

    * python: tarfile module directory traversal (CVE-2007-4559)

    * python: int() type in PyLong_FromString() does not limit amount of digits converting text to int leading
    to DoS (CVE-2020-10735)

    * python: CPU denial of service via inefficient IDNA decoder (CVE-2022-45061)

    * python: use after free in heappushpop() of heapq module (CVE-2022-48560)

    * python: DoS when processing malformed Apple Property List files in binary format (CVE-2022-48564)

    * python: Parsing errors in email/_parseaddr.py lead to incorrect value in email address part of tuple
    (CVE-2023-27043)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.");
