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.
