{"id":"ALPINE-CVE-2020-14383","details":"A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not.","modified":"2026-09-11T10:17:51.384325809Z","published":"2020-12-02T01:15:12.170Z","upstream":["CVE-2020-14383"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-14383"}],"affected":[{"package":{"name":"samba","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.11.16-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.12.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-14383.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
