Description Prasad Pandit 2016-12-20 12:42:46 UTC

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.
