FreeBSD : Cyrus IMAPd -- IMAPMAGICPLUS preauthentification overflow (816fdd8b-3d14-11d9-8818-008088034841)

This script is Copyright (C) 2005-2013 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

When the option imapmagicplus is activated on a server the PROXY and
LOGIN commands suffer a standard stack overflow, because the username
is not checked against a maximum length when it is copied into a
temporary stack buffer. This bug is especially dangerous because it
can be triggered before any kind of authentification took place.
