CVE-2016-6490 Qemu: virtio: infinite loop in virtqueue_pop
Quick emulator(Qemu) built with the virtio framework is vulnerable to an
infinite loop issue. It could occur if the guest was to set the I/O descriptor
buffer length to be zero. A privileged user inside guest could use this flaw
to potentially crash the Qemu instance on the host resulting in DoS.
