Description Prasad Pandit 2017-02-15 11:27:25 UTC 
Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support
for the virtio GPU, is vulnerable to an OOB array access issue. It could occur
when creating vertex elements array in vrend_create_vertex_elements_state().

A guest user/process could use this flaw to crash the Qemu process instance
resulting DoS.
