Descriptions

The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 does not properly validate USB configuration descriptor objects, which allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet.

La función is_rndis en el dispositivo de emulación USB Net (hw/usb/dev-network.c) en QEMU en versiones anteriores a 2.5.1 no valida correctamente objetos descriptores de configuración USB, lo que permite a administradores locales del SO invitado provocar una denegación de servicio (referencia a puntero NULL y caída del proceso QEMU) a través de vectores que involucran un paquete de mensajes de control remoto de NDIS.
