<p>An update that solves one vulnerability can now be installed.</p>
<h2>Description:</h2>
<p>This update for bind fixes the following issues:</p>
<p>Upgrade to release 9.20.18:</p>
<ul>
<li>CVE-2025-13878: Fixed incorrect length checks for BRID and HHIT records (bsc#1256997)</li>
</ul>
<p>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.</p>
<p>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.</p>
