<bug_vulnerability_class>Buffer Overflow</bug_vulnerability_class>
<bug_description>The Mercur Mailserver is a small Mail Transfer Agent (MTA). It has been reported that there is an insufficient bounds checking in the Control-Service component, which listens on TCP port 32000 by default. An attacker may use this buffer overflow by sending an very long username/password to run arbritrary code with the server privileges.</bug_description>
<bug_solution>It may be possible that there is a new software version available. At the moment the vulnerability is only reported for MERCUR Mailserver 3.3 to 4.2. Please visit the web site of Atrium Software at http://www.atrium-software.com/mercur/mercur_e.html. Limit unwanted connections and communications with firewalling.</bug_solution>
