CVE-2017-5937 virglrenderer: null pointer dereference in vrend_clear
Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support
for the virtio GPU, is vulnerable to a null pointer dereference issue. It
could occur when a guest invokes a virgl 'VIRGL_CCMD_CLEAR' command.
A guest user/process could use this flaw to crash Qemu process resulting in DoS.
