NVD Description

Note: Versions mentioned in the description apply only to the upstream dovecot-pgsql package and not the dovecot-pgsql package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Doveadm credentials are verified using direct comparison which is susceptible to timing oracle attack. An attacker can use this to determine the configured credentials. Figuring out the credential will lead into full access to the affected component. Limit access to the doveadm http service port, install fixed version. No publicly available exploits are known.
