"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-141783 advisory.

    There is a HIGH severity vulnerability affecting the CPython zipfile
    module affecting zipfile.Path. Note that the more common API zipfile.ZipFile class is unaffected.





    When iterating over names of entries in a zip archive (for example, methods
    of zipfile.Path like namelist(), iterdir(), etc)
    the process can be put into an infinite loop with a maliciously crafted
    zip archive. This defect applies when reading only metadata or extracting
    the contents of the zip archive. Programs that are not handling
    user-controlled zip archives are not affected.

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.");
