Descriptions

PHP before 5.3.9 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

PHP anterior a v5.3.9 calcula los valores hash de los parámetros de forma, sin restringir la capacidad de desencadenar colisiones hash predecible, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de CPU) mediante el envío de gran cantidad de parámetros a mano.
