"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-141791 advisory.

    There is a MEDIUM severity vulnerability affecting CPython.

    The
    email module didnt properly quote newlines for email headers when
    serializing an email message allowing for header injection when an email
     is serialized.

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.");
