Description Prasad J Pandit 2016-08-22 05:51:37 EDT 
Quick Emulator(Qemu) built with the VMWARE VMXNET3 NIC device support,
with network abstraction layer is vulnerable to an infinite loop issue.
It could occur while fragmenting packets in the device.

A privileged user inside guest could use this flaw to crash the Qemu instance
resulting in DoS.
