    A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of
    DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS
    resolver) to manipulate records.(CVE-2023-7008)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization systemd security
advisory.

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