NVD Description

Note: Versions mentioned in the description apply only to the upstream dovecot24-backend-pgsql package and not the dovecot24-backend-pgsql package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

When cache is enabled, some passdb/userdb drivers incorrectly cache all users with same cache key, causing wrong cached information to be used for these users. After cached login, all subsequent logins are for same user. Install fixed version or disable caching either globally or for the impacted passdb/userdb drivers. No publicly available exploits are known.
