<bug_vulnerability_class>Denial Of Service</bug_vulnerability_class>
<bug_description>The remote host is running a version of the JanaServer which is vulnerable  to various denial of service vulnerabilities. An attacker may exploit these vulnerabilities by sending a malformed request to the remote service and cause it to enter an infinite loop, thus refusing connections and using 100% of the CPU of the remote host.</bug_description>
<bug_solution>Upgrade to JanaServer 2.4.5 or newer.</bug_solution>
