high Nessus Plugin ID 331849

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3452-1 advisory.

- 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.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected bind, bind-doc and / or bind-utils packages.
