The message parsing feature in Dovecot 1.1.4 and 1.1.5, when using the FETCH ENVELOPE command in the IMAP client, allows remote attackers to cause a denial of service (persistent crash) via an email with a malformed From address, which triggers an assertion error, aka "invalid message address parsing bug."

Security readout for executives and security teams

This issue can make affected Dovecot IMAP mail service crash when it processes a malformed email address during message metadata retrieval. The main business impact is mail availability: users may lose IMAP access until the service is recovered or the bad message is handled. Exposure is most likely on legacy systems still running Dovecot 1.1.4 or 1.1.5 with IMAP accessible to users or the internet. Current supported Dovecot deployments are not identified as affected in the source bundle. Prioritize if the organization still operates legacy Dovecot IMAP infrastructure. This is an availability risk to email service, not a documented data theft or code execution issue in the provided sources. Mitigation focus: Inventory mail servers for Dovecot 1.1.4 or 1.1.5.; Upgrade affected Dovecot packages using vendor-supported advisories.; Review the referenced Dovecot 1.1.6 release and distribution advisories..
