{"id":"DEBIAN-CVE-2026-123582","details":"The validating recursive resolver and validating forwarder in Hickory DNS (hickory-server) 0.25.0 before 0.26.2 do not check whether the SOA record passed DNSSEC validation when assembling NXDOMAIN or NODATA responses. An attacker able to supply forged DNS responses can have a forged SOA record returned to clients with the AD bit set, misleading clients that rely on the server's DNSSEC validation.","modified":"2026-11-08T16:00:07.908743068Z","published":"2026-11-08T02:16:51.853Z","upstream":["CVE-2026-123582"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-123582"}],"affected":[{"package":{"name":"rust-hickory-server","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-hickory-server?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.24.4-2","0.25.2-1","0.25.2-2","0.25.2-3","0.25.2-4","0.26.1-1","0.26.1-2","0.26.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123582.json"}},{"package":{"name":"rust-hickory-server","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-hickory-server?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.26.3-1"}]}],"versions":["0.24.4-2","0.25.2-1","0.25.2-2","0.25.2-3","0.25.2-4","0.26.1-1","0.26.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123582.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
