"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-141778 advisory.

    The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses
    were designated as globally reachable or private. This affected the is_private and is_global
    properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and
    ipaddress.IPv6Network classes, where values wouldnt be returned in accordance with the latest
    information from the IANA Special-Purpose Address Registries.

    CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended
    behavior.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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