"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-109793 advisory.

    library/glob.html in the Python 2 and 3 documentation before 2016 has potentially misleading information
    about whether sorting occurs, as demonstrated by irreproducible cancer-research results. NOTE: the effects
    of this documentation cross application domains, and thus it is likely that security-relevant code
    elsewhere is affected. This issue is not a Python implementation bug, and there are no reports that NMR
    researchers were specifically relying on library/glob.html. In other words, because the older
    documentation stated finds all the pathnames matching a specified pattern according to the rules used by
    the Unix shell, one might have incorrectly inferred that the sorting that occurs in a Unix shell also
    occurred for glob.glob. There is a workaround in newer versions of Willoughby nmr-data_compilation-p2.py
    and nmr-data_compilation-p3.py, which call sort() directly.

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.");
