Description Prasad J Pandit 2017-02-17 00:50:41 EST
Quick Emulator(Qemu) built with the VMWARE VMXNET3 NIC device support
is vulnerable to an out-of-bounds access issue. It could occur while
stripping VLAN header from 'eth_buf' buffer in receiving packets.

A remote user/process could use this issue to crash Qemu process instance
resulting in DoS.

Note:- It requires 'VLANSTRIP' feature is enabled on the vmxnet3 device.
