    The archive/zip package's handling of certain types of invalid zip files differs from the behavior of most
    zip implementations. This misalignment could be exploited to create an zip file with contents that vary
    depending on the implementation reading the file. The archive/zip package now rejects files containing
    these errors. (CVE-2024-24789)

    The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6
    addresses, returning false for addresses which would return true in their traditional IPv4 forms.
    (CVE-2024-24790)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
