CVE request: Qemu: net: buffer overflow in stellaris_enet emulator

[P J P <ppandit () redhat com>]

  Hello,

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.

team at Intel Inc.
