Description Andrej Nemec 2016-10-21 11:14:29 UTC

There is an error in protocol parsing logic of mod_cluster load balancer Apache HTTP Server modules that allows attacker to cause a Segmentation Fault in the serving httpd process. The vector is mod_cluster service messages that are used by worker nodes to communicate their status, load and deployed applications to the mod_cluster balancer. With proper production configuration, the VirtualHost accepting these messages is accessible only from an internal network where worker nodes reside. The error cannot be exploited from the Internet by arbitrary clients.
