Descriptions

The IATA (ata) driver in FreeBSD 6.0 and 8.0, when read access to /dev is available, allows local users to cause a denial of service (kernel panic) via a certain IOCTL request with a large count, which triggers a malloc call with a large value.

El controlador IATA (ata) en FreeBSD v6.0 y v8.0, cuando está disponible la lectura en el directorio /dev, permite a usuarios locales provocar una denegación de servicio (kernel panic) a través de ciertas peticiones IOCTL con un "count" largo, que provoca una llamada para la reserva de memoria (malloc) con un valor largo.
