Descriptions

Integer overflow in the WebSocketChannel class in the WebSockets subsystem in Mozilla Firefox before 48.0 and Firefox ESR < 45.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted packets that trigger incorrect buffer-resize operations during buffering.

Desbordamiento de enteros en la clase WebSocketChannel en el subsistema WebSockets en Mozilla Firefox en versiones anteriores a la 48.0 y Firefox ESR en versiones anteriores a la 45.4 permite que los atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (corrupción de memoria) mediante paquetes manipulados que desencadenan operaciones de redimensionamiento de búfer incorrectas durante el "buffering".
