Quick Emulator(Qemu) built with the Virtio GPU Device emulator support is
vulnerable to an OOB read issue. It could occur while processing
'VIRTIO_GPU_CMD_SET_SCANOUT:' command.

A guest user/process could use this flaw to crash the Qemu process instance
resulting in Dos.

http://git.qemu.org/?p=qemu.git;a=commit;h=2fe760554eb3769d70f608a158474f

The scanout id should not be above the configured num_scanouts.

Use CVE-2016-10029.
