Synopsis :

The remote IMAP server is affected by a remote integer overflow

Description :

According to its banner, the remote Cyrus IMAP server is vulnerable to
a pre-login buffer overrun.

An attacker without a valid login could exploit this, and would be
able to execute arbitrary commands as the owner of the Cyrus process.
This would allow full access to all users' mailboxes.

the time of writing no official fix was available. There is a source
patch against 2.1.10 in the Bugtraq report.
