{"id":"ALPINE-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":"2026-03-09T00:56:24.176366Z","published":"2017-05-11T14:29:58.077Z","upstream":["CVE-2016-2126"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2016-2126"}],"affected":[{"package":{"name":"samba","ecosystem":"Alpine:v3.2","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.14-r1"}]}],"versions":["3.2.10-r0","3.2.11-r0","3.2.11-r1","3.2.8-r0","3.2.8-r1","3.3.4-r0","3.3.5-r0","3.3.5-r1","3.3.5-r2","3.3.6-r0","3.3.7-r0","3.3.7-r1","3.3.7-r2","3.3.7-r3","3.3.7-r4","3.3.8-r0","3.4.3-r0","3.4.3-r1","3.4.4-r0","3.4.5-r0","3.4.5-r1","3.4.7-r0","3.4.7-r1","3.5.10-r0","3.5.11-r0","3.5.2-r0","3.5.3-r0","3.5.4-r0","3.5.4-r1","3.5.5-r0","3.5.6-r0","3.5.6-r1","3.5.6-r2","3.5.6-r3","3.5.6-r4","3.5.7-r0","3.5.8-r0","3.5.9-r0","3.5.9-r1","3.6.1-r0","3.6.1-r1","3.6.1-r2","3.6.10-r0","3.6.11-r0","3.6.12-r0","3.6.13-r0","3.6.13-r1","3.6.15-r0","3.6.16-r0","3.6.19-r0","3.6.19-r1","3.6.2-r0","3.6.3-r0","3.6.4-r0","3.6.4-r1","3.6.5-r0","3.6.6-r0","3.6.7-r0","3.6.7-r1","3.6.8-r0","3.6.8-r1","3.6.9-r0","4.1.0-r1","4.1.0-r2","4.1.1-r0","4.1.10-r0","4.1.11-r0","4.1.12-r0","4.1.13-r0","4.1.14-r0","4.1.14-r1","4.1.15-r0","4.1.16-r0","4.1.17-r0","4.1.2-r0","4.1.3-r0","4.1.3-r1","4.1.3-r2","4.1.4-r0","4.1.5-r0","4.1.5-r1","4.1.6-r0","4.1.7-r0","4.1.8-r0","4.1.9-r0","4.2.0-r0","4.2.0-r1","4.2.1-r0","4.2.1-r1","4.2.1-r2","4.2.11-r0","4.2.14-r0","4.2.7-r0","4.2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2016-2126.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.3","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.14-r1"}]}],"versions":["3.2.10-r0","3.2.11-r0","3.2.11-r1","3.2.8-r0","3.2.8-r1","3.3.4-r0","3.3.5-r0","3.3.5-r1","3.3.5-r2","3.3.6-r0","3.3.7-r0","3.3.7-r1","3.3.7-r2","3.3.7-r3","3.3.7-r4","3.3.8-r0","3.4.3-r0","3.4.3-r1","3.4.4-r0","3.4.5-r0","3.4.5-r1","3.4.7-r0","3.4.7-r1","3.5.10-r0","3.5.11-r0","3.5.2-r0","3.5.3-r0","3.5.4-r0","3.5.4-r1","3.5.5-r0","3.5.6-r0","3.5.6-r1","3.5.6-r2","3.5.6-r3","3.5.6-r4","3.5.7-r0","3.5.8-r0","3.5.9-r0","3.5.9-r1","3.6.1-r0","3.6.1-r1","3.6.1-r2","3.6.10-r0","3.6.11-r0","3.6.12-r0","3.6.13-r0","3.6.13-r1","3.6.15-r0","3.6.16-r0","3.6.19-r0","3.6.19-r1","3.6.2-r0","3.6.3-r0","3.6.4-r0","3.6.4-r1","3.6.5-r0","3.6.6-r0","3.6.7-r0","3.6.7-r1","3.6.8-r0","3.6.8-r1","3.6.9-r0","4.1.0-r1","4.1.0-r2","4.1.1-r0","4.1.10-r0","4.1.11-r0","4.1.12-r0","4.1.13-r0","4.1.14-r0","4.1.14-r1","4.1.15-r0","4.1.16-r0","4.1.17-r0","4.1.2-r0","4.1.3-r0","4.1.3-r1","4.1.3-r2","4.1.4-r0","4.1.5-r0","4.1.5-r1","4.1.6-r0","4.1.7-r0","4.1.8-r0","4.1.9-r0","4.2.0-r0","4.2.0-r1","4.2.1-r0","4.2.1-r1","4.2.1-r2","4.2.11-r0","4.2.14-r0","4.2.3-r0","4.2.3-r1","4.2.3-r2","4.2.3-r3","4.2.7-r0","4.2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2016-2126.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.4","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.4.5-r2"}]}],"versions":["3.2.10-r0","3.2.11-r0","3.2.11-r1","3.2.8-r0","3.2.8-r1","3.3.4-r0","3.3.5-r0","3.3.5-r1","3.3.5-r2","3.3.6-r0","3.3.7-r0","3.3.7-r1","3.3.7-r2","3.3.7-r3","3.3.7-r4","3.3.8-r0","3.4.3-r0","3.4.3-r1","3.4.4-r0","3.4.5-r0","3.4.5-r1","3.4.7-r0","3.4.7-r1","3.5.10-r0","3.5.11-r0","3.5.2-r0","3.5.3-r0","3.5.4-r0","3.5.4-r1","3.5.5-r0","3.5.6-r0","3.5.6-r1","3.5.6-r2","3.5.6-r3","3.5.6-r4","3.5.7-r0","3.5.8-r0","3.5.9-r0","3.5.9-r1","3.6.1-r0","3.6.1-r1","3.6.1-r2","3.6.10-r0","3.6.11-r0","3.6.12-r0","3.6.13-r0","3.6.13-r1","3.6.15-r0","3.6.16-r0","3.6.19-r0","3.6.19-r1","3.6.2-r0","3.6.3-r0","3.6.4-r0","3.6.4-r1","3.6.5-r0","3.6.6-r0","3.6.7-r0","3.6.7-r1","3.6.8-r0","3.6.8-r1","3.6.9-r0","4.1.0-r1","4.1.0-r2","4.1.1-r0","4.1.10-r0","4.1.11-r0","4.1.12-r0","4.1.13-r0","4.1.14-r0","4.1.14-r1","4.1.15-r0","4.1.16-r0","4.1.17-r0","4.1.2-r0","4.1.3-r0","4.1.3-r1","4.1.3-r2","4.1.4-r0","4.1.5-r0","4.1.5-r1","4.1.6-r0","4.1.7-r0","4.1.8-r0","4.1.9-r0","4.2.0-r0","4.2.0-r1","4.2.1-r0","4.2.1-r1","4.2.1-r2","4.2.3-r0","4.2.3-r1","4.2.3-r2","4.2.3-r3","4.2.7-r0","4.2.9-r0","4.2.9-r1","4.4.2-r0","4.4.2-r1","4.4.3-r0","4.4.5-r0","4.4.5-r1"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2016-2126.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
