Multiple security vulnerabilities have been identified in the BIND 9 DNS server software affecting various versions prior to 9.18.21-16.oe2403sp3. These include excessive resource consumption from specially crafted DNS messages, memory corruption via replayed GSS-TSIG signed UDP messages potentially leading to remote code execution, assertion failures causing server aborts when processing redirects with qname-minimization strict enabled, and denial of service from specific recursive query sequences with RPZ zones configured. The vulnerabilities impact DNS resolver and recursive server components.
