{"id":"ALPINE-CVE-2018-16853","details":"Samba from version 4.7.0 has a vulnerability that allows a user in a Samba AD domain to crash the KDC when Samba is built in the non-default MIT Kerberos configuration. With this advisory the Samba Team clarify that the MIT Kerberos build of the Samba AD DC is considered experimental. Therefore the Samba Team will not issue security patches for this configuration. Additionally, Samba 4.7.12, 4.8.7 and 4.9.3 have been issued as security releases to prevent building of the AD DC with MIT Kerberos unless --with-experimental-mit-ad-dc is specified to the configure command.","modified":"2026-07-08T04:30:13.935397587Z","published":"2018-11-28T14:29:00.533Z","upstream":["CVE-2018-16853"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2018-16853"}],"affected":[{"package":{"name":"samba","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-16853.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"4.8.7-r0"}]}],"ecosystem_specific":
