Affected Products:
* openSUSE Leap 15.6
* SUSE Linux Enterprise Server 15 SP6
* SUSE Linux Enterprise Server 15 SP6 LTSS
* SUSE Linux Enterprise Server for SAP Applications 15 SP6
An update that solves eight vulnerabilities can now be installed.
## Description:
This update for bind fixes the following issues:
* CVE-2026-10723: accepting incorrect child-zone NSEC3 records as valid can
allow an attacker to forge authenticated NXDOMAIN responses for sibling
zones (bsc#1271982).
* CVE-2026-10822: storing a DNS key record with an invalid PRIVATEDNS
algorithm identifier length can trigger a consistency check failure
(bsc#1271983).
* CVE-2026-11331: handling NAMETOOLONG error conditions incorrectly during RPZ
wildcard CNAME processing can allow bypassing RPZ rules or triggering
process exits (bsc#1271984).
* CVE-2026-11622: DNSSEC validating resolver under a random subdomain attack
can suffer from runaway memory usage exceeding max-cache-size and affecting
response rate (bsc#1271986).
* CVE-2026-11721: RRSIG with fewer labels than its containing zone when synth-
from-dnssec is enabled can lead to wildcard generation (bsc#1271987).
* CVE-2026-12617: delayed or specific CNAME/DNAME query responses combined
with positive A record responses can trigger an assertion failure
(bsc#1271988).
* CVE-2026-13204: validating a domain covered by both NSEC and NSEC3 with an
RRSIG for only one type can trigger an assertion failure (bsc#1271989).
* CVE-2026-13321: NSEC records with a `Next Domain Name` pointing outside the
signer's zone can allow cross-zone cache poisoning and authenticated denial-
of-service responses (bsc#1271990).
* Update to release 9.18.50:
* Remove ineffective TCP fallback after repeated UDP timeouts.
* Fall back to TCP on receipt of a UDP response with a mismatched query ID.
* Fix DNS64 owner case after DNAME restart.
* Clear REDIRECT flag when it isn't needed.
