Descriptions

Multiple integer overflows in the http_request_forward_body function in proto_http.c in HAProxy 1.5-dev23 before 1.5.4 allow remote attackers to cause a denial of service (crash) via a large stream of data, which triggers a buffer overflow and an out-of-bounds read.

Múltiples desbordamientos de enteros en la función http_request_forward_body en proto_http.c en HAProxy 1.5-dev23 anterior a 1.5.4 permiten a atacantes remotos causar una denegación de servicio (caída) a través de un flujo grande de datos, lo que provoca un desbordamiento de buffer y una lectura fuera de rango.

A buffer overflow flaw was discovered in the way HAProxy handled, under very specific conditions, data uploaded from a client. A remote attacker could possibly use this flaw to crash HAProxy.
