CWE-863  (opens in a new tab)

How to fix?

Upgrade Echo:latest dovecot to version 1:1.0.15-2.2 or higher.

NVD Description

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

The ACL plugin in Dovecot before 1.1.4 treats negative access rights as if they are positive access rights, which allows attackers to bypass intended access restrictions.
