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)
