Description Prasad J Pandit 2017-01-23 13:17:17 EST 
Quick Emulator(Qemu) built with the Virtio GPU Device emulator support is
vulnerable to a memory leakage issue. It could occur while processing
'VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING' command.

A guest user/process could use this flaw to leak host memory resulting in DoS.
