Description Timothy Walsh 2016-04-12 12:11:43 UTC 
It is possible to remotely Segfault
Apache http server with a specially crafted string
sent to the mod_cluster via service messages (MCMP).

Only the VirtualHost explicitly enabled by an administrator
to receive service messages from worker nodes (Tomcat or EAP workers).
Unless the administrator made a grave mistake in opening an
unsecured mod_cluster management VirtualHost to
the Internet without any authentication, it is impossible
to exploit this bug from an untrusted client.

Special set of mod_cluster management protocol HTTP method
requests. One could pass a certain number of = symbols
in sequence after a legitimate element and cause segfault.
