Important: bind9.16 security, bug fix, and enhancement update
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: bind: BIND 9: Denial of Service via 16-bit length truncation in DNS negative cache handling (CVE-2026-19667) * bind: BIND: Denial of Service via crafted DNSSEC reply (CVE-2026-80274) * bind: BIND: Denial of Service via malformed DNS64 responses (CVE-2026-19666) Bug Fix(es) and Enhancement(s): * bind 9.16 crash with SIGSEGV (JIRA:AlmaLinux-273294) 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.
