"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in

    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols.
    BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing
    with DNS); and tools for verifying that the DNS server is operating correctly.

    Security Fix(es):

    * bind: named's configured cache size limit can be significantly exceeded (CVE-2023-2828)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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