Description Prasad J Pandit 2017-02-27 08:55:50 UTC
Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support
for the virtio GPU, is vulnerable to an integer overflow issue. It could occur
when creating a shader object in vrend_create_shader().

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