A vulnerability has been reported in the Apache mod_proxy module, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the "ap_proxy_http_process_response()" function when forwarding interim responses. This can be exploited to consume large amounts of memory by tricking mod_proxy into sending an overly large number of interim responses to the client.
The vulnerability is reported in versions 2.2.8 and 2.0.63. Other versions may also be affected.
Solution: Update to version 2.2.9 or 2.0.64.
Provided and/or discovered by: The vendor credits Ryujiro Shibuya.
