Description Tomas Hoger 2011-09-08 08:31:40 EDT
mod_proxy_ajp did not correctly process certain malformed HTTP requests, which could cause it to incorrectly put a backend server to an error state until the retry timeout expired.  A remote attacker could send malicious requests to trigger this issue, resulting in a temporary denial of service.
