{"id":"UBUNTU-CVE-2024-25584","details":"Dovecot accepts dot LF DOT LF symbol as end of DATA command. RFC requires that it should always be CR LF DOT CR LF. This causes Dovecot to convert single mail with LF DOT LF in middle, into two emails when relaying to SMTP. Dovecot will split mail with LF DOT LF into two mails. Upgrade to latest released version. No publicly available exploits are known.","modified":"2026-02-04T03:06:41.747346Z","published":"2024-09-06T15:15:00Z","withdrawn":"2025-06-23T15:57:37Z","related":["CVE-2024-25584"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-25584"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-25584"},{"type":"REPORT","url":"https://documentation.open-xchange.com/dovecot/security/advisories/csaf/2024/oxdc-adv-2024-0001.json"}],"affected":[{"package":{"name":"dovecot","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:2.1.7-7ubuntu3","1:2.2.9-1ubuntu1","1:2.2.9-1ubuntu2","1:2.2.9-1ubuntu2.1","1:2.2.9-1ubuntu2.3","1:2.2.9-1ubuntu2.4","1:2.2.9-1ubuntu2.5","1:2.2.9-1ubuntu2.6","1:2.2.9-1ubuntu2.6+esm2","1:2.2.9-1ubuntu2.6+esm3","1:2.2.9-1ubuntu2.6+esm4"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25584.json"}},{"package":{"name":"dovecot","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:2.2.18-2ubuntu2","1:2.2.22-1ubuntu1","1:2.2.22-1ubuntu2","1:2.2.22-1ubuntu2.1","1:2.2.22-1ubuntu2.2","1:2.2.22-1ubuntu2.3","1:2.2.22-1ubuntu2.4","1:2.2.22-1ubuntu2.6","1:2.2.22-1ubuntu2.7","1:2.2.22-1ubuntu2.8","1:2.2.22-1ubuntu2.9","1:2.2.22-1ubuntu2.10","1:2.2.22-1ubuntu2.11","1:2.2.22-1ubuntu2.12","1:2.2.22-1ubuntu2.13","1:2.2.22-1ubuntu2.14"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25584.json"}},{"package":{"name":"dovecot","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:2.2.27-3ubuntu1","1:2.2.33.2-1ubuntu1","1:2.2.33.2-1ubuntu2","1:2.2.33.2-1ubuntu3","1:2.2.33.2-1ubuntu4","1:2.2.33.2-1ubuntu4.1","1:2.2.33.2-1ubuntu4.2","1:2.2.33.2-1ubuntu4.3","1:2.2.33.2-1ubuntu4.4","1:2.2.33.2-1ubuntu4.5","1:2.2.33.2-1ubuntu4.6","1:2.2.33.2-1ubuntu4.7","1:2.2.33.2-1ubuntu4.8"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25584.json"}},{"package":{"name":"dovecot","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:2.3.4.1-5ubuntu3","1:2.3.7.2-1ubuntu1","1:2.3.7.2-1ubuntu2","1:2.3.7.2-1ubuntu3","1:2.3.7.2-1ubuntu3.1","1:2.3.7.2-1ubuntu3.2","1:2.3.7.2-1ubuntu3.3","1:2.3.7.2-1ubuntu3.4","1:2.3.7.2-1ubuntu3.5","1:2.3.7.2-1ubuntu3.6"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25584.json"}},{"package":{"name":"dovecot","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:2.3.13+dfsg1-1ubuntu3","1:2.3.16+dfsg1-3ubuntu1","1:2.3.16+dfsg1-3ubuntu2","1:2.3.16+dfsg1-3ubuntu2.1","1:2.3.16+dfsg1-3ubuntu2.2"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25584.json"}},{"package":{"name":"dovecot","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/dovecot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:2.3.20+dfsg1-1ubuntu3","1:2.3.21+dfsg1-2ubuntu1","1:2.3.21+dfsg1-2ubuntu2","1:2.3.21+dfsg1-2ubuntu4","1:2.3.21+dfsg1-2ubuntu5","1:2.3.21+dfsg1-2ubuntu6"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25584.json"}}],"schema_version":"1.7.3"}
