<p>An update that solves four vulnerabilities and has one security fix can now be installed.</p>
<h2>Description:</h2>
<p>This update for bind fixes the following issues:</p>
<p>Security issues:</p>
<ul>
<li>CVE-2026-1519: maliciously crafted DNSSEC-validated zone can lead to denial of service (bsc#1260805).</li>
<li>CVE-2026-3104: memory leak in code preparing DNSSEC proofs of non-existence allows for DoS (bsc#1260567).</li>
<li>CVE-2026-3119: authenticated queries containing a TKEY record may cause <code>named</code> to terminate unexpectedly
(bsc#1260568).</li>
<li>CVE-2026-3591: stack use-after-return flaw in SIG(0) handling code allows for ACL bypass (bsc#1260569).</li>
<li>use-after-free error in <code>dns_client_resolve()</code> triggered by a DNAME response (bsc#1259202).</li>
</ul>
<p>Upgrade to release 9.20.21
Security Fixes:
* Fix unbounded NSEC3 iterations when validating referrals to
unsigned delegations.
(CVE-2026-1519)
[bsc#1260805]
* Fix memory leaks in code preparing DNSSEC proofs of
non-existence.
(CVE-2026-3104)
[bsc#1260567]
* Prevent a crash in code processing queries containing a TKEY
record.
(CVE-2026-3119)
[bsc#1260568]
* Fix a stack use-after-return flaw in SIG(0) handling code.
(CVE-2026-3591)
[bsc#1260569]
* Fix a use-after-free error in dns_client_resolve() triggered by
a DNAME response. This issue only affected the delv tool and it
has now been fixed.
[bsc#1259202]
Feature Changes:
* Record query time for all dnstap responses.
* Optimize TCP source port selection on Linux.
Bug Fixes:
* Fix the handling of key statements defined inside views.
* Fix an assertion failure triggered by non-minimal IXFRs.
* Fix a crash when retrying a NOTIFY over TCP.
* Fetch loop detection improvements.
* Randomize nameserver selection.
* Fix dnstap logging of forwarded queries.
* A stale answer could have been served in case of multiple
upstream failures when following CNAME chains. This has been
fixed.
* Fail DNSKEY validation when supported but invalid DS is found.
* Importing an invalid SKR file might corrupt stack memory.
* Return FORMERR for queries with the EDNS Client Subnet FAMILY
field set to 0.
* Fix inbound IXFR performance regression.
* Make catalog zone names and member zones' entry names
case-insensitive.
* Fix implementation of BRID and HHIT record types.
* Fix implementation of DSYNC record type.
* Fix response policy and catalog zones to work with $INCLUDE
directive.</p>
