Descriptions

Heap-based buffer overflow in the proxy_connect function in src/client.c in CVS 1.11 and 1.12 allows remote HTTP proxy servers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted HTTP response.

Desbordamiento de búfer basado en memoria dinámica en la funcion proxy_connect en src/client.c en CVS v1.11 y v1.12 permite a los servidores proxy HTTP remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de una respuesta HTTP manipulada.

A heap-based buffer overflow in CVS might allow remote attackers to execute arbitrary code. Versions less than 1.12.12-r11 are affected.
