{"id":"ALPINE-CVE-2020-28896","details":"Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.","modified":"2026-11-03T06:32:46.015756263Z","published":"2020-11-23T19:15:11.413Z","upstream":["CVE-2020-28896"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-28896"}],"affected":[{"package":{"name":"mutt","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}},{"package":{"name":"mutt","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/mutt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-28896.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
