Background

Description

Impact

A remote attacker could possibly cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Dovecot users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-mail/dovecot-2.2.13"
