lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message.

Security readout for executives and security teams

This is a Dovecot mail server denial-of-service flaw. Very old Dovecot versions can mishandle null characters in email header names, letting a remote sender crash a daemon or corrupt a mailbox with a crafted message. It matters mainly where legacy Dovecot is still serving mail. Exposure is likely limited to organizations still running Dovecot 1.2.x before 1.2.17 or 2.0.x before 2.0.13, including old distribution packages. Internet-facing mail servers are the main concern because delivery of a crafted email is the stated trigger. Prioritize remediation if any legacy Dovecot servers are still internet-facing or business-critical. For modern, patched environments, urgency is lower. The business risk is service disruption and possible mailbox corruption, not documented data theft or code execution in the supplied sources. Mitigation focus: Upgrade Dovecot 1.2.x to 1.2.17 or later.; Upgrade Dovecot 2.0.x to 2.0.13 or later.; Apply distribution security updates from Debian, Fedora, Red Hat, or other vendor packages..
