JSON

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.

Bugs

Notes

Author	Note
tyhicks	privileged users inside the guest can trigger a DoS but they could also simply shut down the guest
