Descriptions

In Sophos Tester Tool 3.2.0.7 Beta, the driver accepts a special DeviceIoControl code that doesn't check its argument. This argument is a memory address: if a caller passes a NULL pointer or a random invalid address, the driver will cause a Blue Screen of Death. If a program or malware does this at boot time, it can cause a persistent denial of service on the machine.

En Sophos Tester Tool 3.2.0.7 Beta, el controlador acepta un código especial DeviceIoControl que no comprueba su argumento. Este argumento es una dirección de memoria: si un llamante pasa un puntero NULL o una dirección aleatoria inválida, el controlador provocará una pantalla azul de la muerte. Si un programa o malware realiza esto en tiempo de arranque, puede provocar una denegación de servicio (DoS) persistente en la máquina.
