CVE-2016-7994 [MEDIUM] CVE-2016-7994 Qemu: virtio-gpu: memory leak in virtio_gpu_resource_create_2d
CVE-2016-7994 Qemu: virtio-gpu: memory leak in virtio_gpu_resource_create_2d
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.
