{"id":"ALSA-2026:54510","summary":"Important: bind security update","details":"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.  \n\nSecurity Fix(es):  \n\n  * bind9: bind: Potential wildcard CNAME RPZ policy bypass (CVE-2026-11331)\n  * bind: bind9: DNSSEC Validation Bypass via Out-of-Zone NSEC Next Field (CVE-2026-13321)\n  * bind: bind9: Potential memory usage beyond configured limits (CVE-2026-11622)\n  * bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards (CVE-2026-11721)\n  * bind: bind9: Unexpected exit with NSEC and NSEC3 both present (CVE-2026-13204)\n  * bind: bind9: Incorrect acceptance of NSEC3 records (CVE-2026-10723)\n\n\nFor more details about the security issue(s), including the impact, a CVSS
