Description Agostino Sarubbo gentoo-dev 2017-02-23 11:49:11 UTC 
From ${URL} :

Virgil 3d project, used by Quick Emulator(Qemu) to implement 3D GPU support
for the virtio GPU, is vulnerable to a null pointer dereference flaw. It could
occur when destroying renderer context zero(0) in 'vrend_decode_reset'.

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