Loading vulnerability…
CVE-2016-8612 is an improper input validation flaw in the protocol-parsing logic of Apache HTTP Server mod_cluster load-balancer modules before httpd 2.4.23. Crafted mod_cluster service messages containing unexpected protocol values can cause the serving httpd process to dereference invalid state and terminate with a segmentation fault. The affected messages are used by mod_cluster worker nodes to report status, load, and deployed applications to the balancer.
