{"id":"DEBIAN-CVE-2026-123598","details":"The validating recursor in Hickory DNS hickory-recursor 0.25.0 through 0.26.0-alpha.1, hickory-resolver 0.26.0-alpha.1 before 0.26.2, and hickory-net 0.26.0-beta.1 before 0.26.2 caches DNSSEC-bogus answers using the untrusted, attacker-supplied record TTL (capped at 24 hours) instead of a short validation-failure TTL. A remote attacker who spoofs a single authoritative response with an invalid signature and a long TTL can keep the bogus result cached for up to 24 hours.","modified":"2026-11-08T16:00:06.931344527Z","published":"2026-11-08T02:16:54.327Z","upstream":["CVE-2026-123598"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-123598"}],"affected":[{"package":{"name":"rust-hickory-net","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-hickory-net?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.26.3-1"}]}],"versions":["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-2026-123598.json"}},{"package":{"name":"rust-hickory-recursor","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-hickory-recursor?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.24.1-1","0.25.2-1","0.25.2-2","0.25.2-3","0.25.2-4","0.25.2-5","0.25.2-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123598.json"}},{"package":{"name":"rust-hickory-recursor","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-hickory-recursor?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.24.1-1","0.25.2-1","0.25.2-2","0.25.2-3","0.25.2-4","0.25.2-5","0.25.2-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123598.json"}},{"package":{"name":"rust-hickory-resolver","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-hickory-resolver?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.24.4-1","0.24.4-2","0.24.4-3","0.24.4-4","0.24.4-5","0.25.2-1","0.25.2-2","0.26.1-1","0.26.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123598.json"}},{"package":{"name":"rust-hickory-resolver","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-hickory-resolver?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.26.3-1"}]}],"versions":["0.24.4-1","0.24.4-2","0.24.4-3","0.24.4-4","0.24.4-5","0.25.2-1","0.25.2-2","0.26.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123598.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:N/A:L"}]}
