<bug_vulnerability_class>Denial Of Service</bug_vulnerability_class>
<bug_description>The remote web server appears to be running a version of Apache that is less that 2.0.49 or 1.3.31. These versions are vulnerable to a denial of service attack where a remote   attacker can block new connections to the server by connecting to a listening socket on a rarely accessed port.</bug_description>
<bug_solution>Upgrade to Apache 2.0.49 or 1.3.31.</bug_solution>
