<bug_vulnerability_class>Buffer Overflow</bug_vulnerability_class>
<bug_description>The remote host is running a version of Kerio MailServer prior to 6.0.1.Kerio Mailserver is an SMTP server which ships with an embedded HTTP server. It has been reported that there are multiple remote overflows in versions of Kerio prior to 6.0.1, although the exact nature of these overflows is not yet known.</bug_description>
<bug_solution>The server should be deactivated or de-installed if not necessary. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8025). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. Upgrade the software to the latest version.</bug_solution>
