CVE-2009-1890 Information

Description

The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server before 2.3.3 when a reverse proxy is configured does not properly handle an amount of streamed data that exceeds the Content-Length value which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests.
