{"id":"DEBIAN-CVE-2026-12490","details":"When a provide-xfr is given with a tls-auth-name, a secondary requesting a transfer should provide a client certificate with that name. However, no client certificate is needed when the request comes in over TLS over the regular tls-port (and not the tls-auth-port) or over over TCP over the regular port, when the other conditions of the provide-xfr rule match.","modified":"2026-09-14T17:01:52.974654533Z","published":"2026-06-25T07:16:45.330Z","upstream":["CVE-2026-12490"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-12490"}],"affected":[{"package":{"name":"nsd","ecosystem":"Debian:12","purl":"pkg:deb/debian/nsd?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.10.1-1","4.10.1~rc2-1","4.10.1~rc2-2","4.11.0-1","4.11.1-1","4.12.0-1","4.12.0-2","4.13.0-1","4.13.0-2","4.13.0-3","4.13.0-4","4.13.0-5","4.13.0-6","4.14.0-1","4.14.1-1","4.14.2-1","4.14.3-1","4.15.0-1","4.15.0~rc1-1","4.15.1-1","4.15.2-1","4.6.1-1","4.7.0-1","4.8.0-1","4.9.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12490.json"}},{"package":{"name":"nsd","ecosystem":"Debian:13","purl":"pkg:deb/debian/nsd?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.0-1","4.12.0-2","4.13.0-1","4.13.0-2","4.13.0-3","4.13.0-4","4.13.0-5","4.13.0-6","4.14.0-1","4.14.1-1","4.14.2-1","4.14.3-1","4.15.0-1","4.15.0~rc1-1","4.15.1-1","4.15.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12490.json"}},{"package":{"name":"nsd","ecosystem":"Debian:14","purl":"pkg:deb/debian/nsd?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.14.3-1"}]}],"versions":["4.12.0-1","4.12.0-2","4.13.0-1","4.13.0-2","4.13.0-3","4.13.0-4","4.13.0-5","4.13.0-6","4.14.0-1","4.14.1-1","4.14.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12490.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
