Description Agostino Sarubbo gentoo-dev 2017-02-02 13:30:44 UTC 
From ${URL} :

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.
