"According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

    It is possible to construct a zone such that some queries to it will generate responses containing
    numerous records in the Additional section. An attacker sending many such queries can cause either the
    authoritative server itself or an independent resolver to use disproportionate resources processing the
    queries. Zones will usually need to have been deliberately crafted to attack this
    exposure.(CVE-2024-11187)

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

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