Descriptions

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.

La función stream_reqbody_cl de mod_proxy_http.c en el módulo mod_proxy del Servidor HTTP de Apache anterior a v2.3.3, cuando está configurado un proxy inverso, no maneja adecuadamente un flujo de datos que exceda el valor de Content-Length (Longitud del Contenido), esto permite a atacantes remotos provocar una denegación de servicio (consumo de la CPU) a través de una solicitud manipulada.
