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

critical Nessus Plugin ID 19004

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.

Solution

Update the affected package.
