===============================================
  Hello,

Quick Emulator(Qemu) built with the Virtio GPU Device emulator support is
vulnerable to a host memory leakage issue. It could occur while processing
'VIRTIO_GPU_CMD_RESOURCE_UNREF' command.


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