<bug_description>The remote host is running an OpenSSH daemon (secure shell). This could be determined by opening a tcp connection and grabbing the banner. An attacker may use this information to start further enumeration or attacks on the target host. It may also be possible that this OpenSSH server is an unwanted backdoor.</bug_description>
<bug_solution>If the SSH server is unused, de-install or de-activate it. If this is not possible, upgrade your SSH server to the latest version to prevent to be vulnerable to known bugs. Try to install the SSH server to another port to make portscanning on default ports harder. Also limit unwanted connections and communications with firewalling.</bug_solution>
