{"id":"ALPINE-CVE-2021-3181","details":"rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons.","modified":"2026-11-03T06:32:33.360956323Z","published":"2021-01-19T15:15:12.327Z","upstream":["CVE-2021-3181"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-3181"}],"affected":[{"package":{"name":"mutt","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.14.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3181.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
