QID 243186: Red Hat Update for bind9.16 (RHSA-2024:1781)

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):

    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).
