Description Prasad Pandit 2016-10-07 10:56:14 UTC 
Quick Emulator built with the Virtio GPU Device support is vulnerable to a
memory leakage issue. It could occur while processing virtio GPU command
VIRTIO_GPU_CMD_RESOURCE_CREATE_2D.

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