Summary
BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols. BIND includes a DNS server (named),
which resolves host names to IP addresses; a resolver library
(routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating properly.
Update Information:
Update to 9.21.17 (rhbz#2415843) Security Fixes: Fix incorrect length checks for BRID and HHIT records. (CVE-2025-13878) New Features: Add support for Extended DNS Error 9 (Missing DNSKEY). Add support for Extended DNS Error 13 (Cached Error). Add support for Generalized DNS Notifications. Features Changes: Add more information to the rndc recursing output about fetches. Enforce bounds of multiple configuration options. Bug Fixes: Fix inbound IXFR performance regression. Make DNSSEC key rollovers more robust. Fix a catalog zone issue, where member zones could fail to load. Fix slow speed when signing a large delegation zone with NSEC3 opt-out. Reconfiguring an NSEC3 opt-out zone to NSEC caused the zone to be invalid. Fix a possible catalog zone issue during reconfiguration. Fix the charts in the statistics channel. https://downloads.isc.org/isc/bind9/9.21.17/doc/arm/html/notes.html#notes-for- bind-9-21-17
