Descriptions

Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.

Desbordamiento de búfer basado en el montón en proxy_util.c de mod_proxy en Apache 1.3.25 a 1.3.31 permite a atacantes remotos causar un denegación de servicio (caída del proceso) y posiblemente ejecutar código de su elección mediante un campo de cabecera HTTP Content-Length negativo, lo que causa que una gran cantidad de datos sean copiados.
