Dovecot 1.2.x before 1.2.8 sets 0777 permissions during creation of certain directories at installation time, which allows local users to access arbitrary user accounts by replacing the auth socket, related to the parent directories of the base_dir directory, and possibly the base_dir directory itself.

Security readout for executives and security teams

Dovecot 1.2.x before 1.2.8 could create some installation directories with world-writable permissions. On affected systems, a local user could interfere with Dovecot authentication socket handling and potentially access other users’ mail accounts. This is mainly a risk for shared systems or servers where untrusted local users exist. Exposure is likely limited to systems running Dovecot 1.2.x before 1.2.8, especially legacy Linux mail servers with local user accounts. Systems installed from vendor packages may have distro-specific fixed builds or backports. Treat as a legacy mail-server hygiene issue unless affected systems still host untrusted local users. Prioritize confirmation and upgrade during maintenance, with higher urgency for shared shell or multi-tenant environments. Mitigation focus: Upgrade Dovecot to 1.2.8 or a vendor-supported fixed package.; Check relevant Linux distribution advisories for backported fixes.; Review Dovecot base_dir and parent directory permissions against vendor guidance..
