If an attacker inserts a malformed zone into a BIND authoritative server (e.g., via zone transfer), queries for names inside the configured zone then lose authoritative status and return an out-of-zone delegation. On a server that also provides recursion BIND can follow this locally sourced cut and cache attacker-supplied data, affecting names outside the configured zone. This situation persists as long as the malformed zone remains in the zone database.\nThis issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.", "references": ["https://kb.isc.org/docs/cve-2026-78301", "https://downloads.isc.org/isc/bind9/9.20.29", "https://downloads.isc.org/isc/bind9/9.21.26"], "fixes": ["1:9.20.29-1~deb13u1"], "products": [{"name": "bind9", "path": "vulns/debian-13/bind9", "ecosystem": "Debian:13"}]}, {"id": "CVE-2026-77692", "noindex": false, "published": "2026-09-16T13:55:45.110Z", "modified": "2026-09-17T18:43:49.422Z", "cvss": 7.5, "cvss_vector": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "severity": "high", "epss": 0.06558, "kev": false, "exploits": [], "stacks": [{"name": "system", "path": "vulns/stack/system", "slug": "system"}], "path": "vulns/cve-2026-77692", "title": "Unauthenticated remote crash of named via a single DoH SIG(0) request", "description": "An attacker can cause `named` to abort by sending a crafted DNS-over-HTTPS request with a cryptographically invalid SIG(0) record, and then closing the transport connection prematurely.\nThis issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1.", "references": ["https://kb.isc.org/docs/cve-2026-77692", "https://downloads.isc.org/isc/bind9/9.20.29", "https://downloads.isc.org/isc/bind9/9.21.26"], "fixes": ["1:9.20.29-1~deb13u1"], "products": [{"name": "bind9", "path": "vulns/debian-13/bind9", "ecosystem": "Debian:13"}]}, {"id": "CVE-2026-19941", "noindex": false, "published": "2026-09-16T13:52:49.400Z", "modified": "2026-09-17T18:44:20.015Z", "cvss": 5.9, "cvss_vector": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N", "severity": "medium", "epss": 0.00226, "kev": false, "exploits": [], "stacks": [{"name": "system", "path": "vulns/stack/system", "slug": "system"}], "path": "vulns/cve-2026-19941", "title": "checkwildcard() accepts an out-of-zone NSEC as a wildcard-nonexistence proof", "description": "An inapplicable NSEC record may be accepted by a `named` resolver as proof that no wildcard exists, which could allow an attacker at the same or an upstream level of the zone name to mask the existence of a victim's wildcard record.\nThis issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.", "references": ["https://kb.isc.org/docs/cve-2026-19941", "https://downloads.isc.org/isc/bind9/9.20.29", "https://downloads.isc.org/isc/bind9/9.21.26"], "fixes": ["1:9.20.29-1~deb13u1"], "products": [{"name": "bind9", "path": "vulns/debian-13/bind9", "ecosystem": "Debian:13"}]}, {"id": "CVE-2026-19662", "noindex": false, "published": "2026-09-16T13:50:10.432Z", "modified": "2026-09-17T18:45:11.717Z", "cvss": 5.9, "cvss_vector": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H", "severity": "medium", "epss": 0.00464, "kev": false, "exploits": [], "stacks": [{"name": "system", "path": "vulns/stack/system", "slug": "system"}], "path": "vulns/cve-2026-19662", "title": "qpcache NOQNAME proof use-after-free crashes recursive resolver", "description": "An attacker may be able to cause a `named` resolver to abort.
