=============================================
  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.
