Description Agostino Sarubbo gentoo-dev 2016-12-14 10:51:12 UTC 
From ${URL} :

Quick Emulator(Qemu) built with the Virtio GPU Device emulator support is 
vulnerable to a memory leakage issue. It could occur while destroying gpu 
resource object in 'virtio_gpu_resource_destroy'

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