Security Fix(es):
bind9.16: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)
bind9.16: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)
bind9.16: Specific recursive query patterns may lead to an out-of-memory condition (CVE-2023-6516)
bind9.16: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution (CVE-2023-5679)
bind9.16: Querying RFC 1918 reverse zones may cause an assertion failure when “nxdomain-redirect” is enabled (CVE-2023-5517)
bind9.16: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)
