Subject: CVE-2017-6355 Virglrenderer: integer overflow while creating shader

   Hello,

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.
