The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1800 advisory.

    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.

    Bind-dyndb-ldap provides an LDAP back-end plug-in for BIND. It features support for dynamic updates and     internal caching, to lift the load off of your LDAP server.

    Security Fix(es):

    * bind9: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)

    * bind9: Querying RFC 1918 reverse zones may cause an assertion failure when nxdomain-redirect is     enabled (CVE-2023-5517)

    * bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution     (CVE-2023-5679)

    * bind9: Specific recursive query patterns may lead to an out-of-memory condition (CVE-2023-6516)

    * bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)

    * bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)

    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 these issues but has instead relied only on the application's self-reported version number.
