Description Prasad J Pandit 2016-04-11 08:20:53 EDT 
Qemu emulator built with the Luminary Micro Stellaris Ethernet Controller
is vulnerable to a buffer overflow issue. It could occur while receiving
network packets in stellaris_enet_receive(), if the guest NIC is configured
to accept large(MTU) packets.

A remote user/process could use this flaw to crash the Qemu process on a host,
resulting in DoS.
