{"id":"DEBIAN-CVE-2016-2126","details":"Samba version 4.0.0 up to 4.5.2 is vulnerable to privilege elevation due to incorrect handling of the PAC (Privilege Attribute Certificate) checksum. A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions.","modified":"2026-04-28T20:15:16.134502Z","published":"2017-05-11T14:29:58.077Z","upstream":["CVE-2016-2126"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2016-2126"}],"affected":[{"package":{"name":"samba","ecosystem":"Debian:11","purl":"pkg:deb/debian/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.5.2+dfsg-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2016-2126.json"}},{"package":{"name":"samba","ecosystem":"Debian:12","purl":"pkg:deb/debian/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.5.2+dfsg-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2016-2126.json"}},{"package":{"name":"samba","ecosystem":"Debian:13","purl":"pkg:deb/debian/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.5.2+dfsg-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2016-2126.json"}},{"package":{"name":"samba","ecosystem":"Debian:14","purl":"pkg:deb/debian/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.5.2+dfsg-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2016-2126.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
