DESCRIPTION:
A weakness has been reported in Dovecot, which can be exploited by
malicious users to bypass certain security restrictions.

The weakness is caused due to the ACL plugin copying INBOX ACLs to
newly created mailboxes if a Maildir with default settings is used,
INBOX is the same directory as the Maildir root directory, and ACLs
are assigned to INBOX.

The weakness is reported in 1.2.x versions prior to 1.2.13.

SOLUTION:
Update to version 1.2.13.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
