## Description:

This update for bind fixes the following issues:

Upgrade to release 9.20.18:

  * CVE-2025-13878: Fixed incorrect length checks for BRID and HHIT records
    (bsc#1256997)

Feature Changes: * Add more information to the rndc recursing output about
fetches. * Reduce the number of outgoing queries. * Provide more information
when memory allocation fails.

Bug Fixes: * Make DNSSEC key rollovers more robust. * Fix a catalog zone issue,
where member zones could fail to load. * Allow glue in delegations with
QTYPE=ANY. * 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. * Adding NSEC3 opt-out records could leave
invalid records in chain. * Fix spurious timeouts while resolving names. * Fix
bug where zone switches from NSEC3 to NSEC after retransfer. * AMTRELAY type 0
presentation format handling was wrong. * Fix parsing bug in remote-servers with
key or TLS. * Fix DoT reconfigure/reload bug in the resolver. * Skip unsupported
algorithms when looking for a signing key. * Fix dnssec-keygen key collision
checking for KEY RRtype keys. * dnssec-verify now uses exit code 1 when failing
due to illegal options. * Prevent assertion failures of dig when a server is
specified before the -b option. * Skip buffer allocations if not logging.
