"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0111 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-6597:
    An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7,
    3.10.13, 3.9.18, and 3.8.18 and prior.
    The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related
    errors. This means users which can run privileged programs are potentially able to modify permissions of
    files referenced by symlinks in some circumstances.

    CVE-2024-0450:
    An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and
    3.8.18 and prior.
    The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip format to create
    a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject
    zip archives which overlap entries in the archive.

Tenable has extracted the preceding description block directly from the Alibaba Cloud 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.");
