It was discovered that the ACL plugin in Dovecot would incorrectly grant
the admin permission to owners of certain mailboxes. A remote authenticated
user could possibly bypass intended access restrictions and gain access to
mailboxes. (CVE-2010-3779)

It was discovered that Dovecot incorrectly handled the simultaneous
disconnect of a large number of sessions. A remote authenticated user could
use this flaw to cause Dovecot to crash, resulting in a denial of service.
