"The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2024:1847-1 advisory.

    - CVE-2023-52425: Fixed backport so it uses features sniffing, not just comparing version number
    (bsc#1219559).
    - CVE-2024-0450: Fixed detecting the vulnerability of 'quoted-overlap' zipbomb (bsc#1221854).
    - CVE-2023-6597: Fixed symlink bug in cleanup of tempfile.TemporaryDirectory (bsc#1219666).
    - CVE-2022-48566: Fixed compare_digest constant-time (bsc#1214691).

    Bug fixes:

    - Fixed syslog making default 'ident from sys.argv[0] (bsc#1222109).

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

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