Description Prasad Pandit 2014-04-14 13:57:26 UTC
An array index bounds overrun flaw has been discovered in the vmxnet3 device
as emulated by qemu.

A privileged guest user could use this flaw to corrupt qemu process' memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the qemu process.
