A vulnerability has been reported in the Apache mod_proxy module, which can be exploited by malicious people to potentially cause a DoS (Denial of Service).

An error exists in the mod_proxy module when functioning in reverse proxy mode. This can be exploited to consume large amounts of CPU in an affected proxy process via specially crafted proxy requests.
