httpd is vulnerable to denial of service. It was discovered that mod_proxy_ajp incorrectly returned an “Internal Server Error” response when processing certain malformed requests, which caused the back-end server to be marked as failed in configurations where mod_proxy is used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period (60 seconds by default) by sending specially-crafted requests.
