According to its banner, the version of Ipswitch IMail installed on
the remote host has several buffer overflows in its IMAP service
component, one of which can be exploited prior to authentication to
execute arbitrary code with SYSTEM privileges. 

In addition, there is also a denial of service issue that can cause
the IM Server to crash without authentication.");
