Description Prasad J Pandit 2017-02-23 10:04:42 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 parsing properties in parse_identifier().

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