{"schemaVersion":3,"id":"SUSE-SU-2026:3452-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for bind\n\nThis update for bind fixes the following issues:\n\n- CVE-2026-10723: accepting incorrect child-zone NSEC3 records as valid can allow an attacker to forge authenticated\n  NXDOMAIN responses for sibling zones (bsc#1271982).\n- CVE-2026-10822: storing a DNS key record with an invalid PRIVATEDNS algorithm identifier length can trigger a\n  consistency check failure (bsc#1271983).\n- CVE-2026-11331: handling NAMETOOLONG error conditions incorrectly during RPZ wildcard CNAME processing can allow\n  bypassing RPZ rules or triggering process exits (bsc#1271984).\n- CVE-2026-11622: DNSSEC validating resolver under a random subdomain attack can suffer from runaway memory usage\n  exceeding max-cache-size and affecting response rate (bsc#1271986).\n- CVE-2026-11721: RRSIG with fewer labels than its containing zone when synth-from-dnssec is enabled can lead to\n  wildcard generation (bsc#1271987).\n- CVE-2026-12617: delayed or specific CNAME/DNAME query responses combined with positive A record responses can trigger\n  an assertion failure (bsc#1271988).\n- CVE-2026-13204: validating a domain covered by both NSEC and NSEC3 with an RRSIG for only one type can trigger an\n  assertion failure (bsc#1271989).\n- CVE-2026-13321: NSEC records with a `Next Domain Name` pointing outside the signer's zone can allow cross-zone cache\n  poisoning and authenticated denial-of-service responses (bsc#1271990).\n\n- Update to release 9.18.50:\n\n * Remove ineffective TCP fallback after repeated UDP timeouts.\n * Fall back to TCP on receipt of a UDP response with a mismatched query ID.\n * Fix DNS64 owner case after DNAME restart.\n * Clear REDIRECT flag when it isn't needed.","dates":{"published":"2026-08-03T11:34:55.000Z","modified":"2026-08-04T11:45:06.336Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"bind&distro=SUSE
