Description Prasad J Pandit 2016-07-29 01:27:55 EDT 
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.
