Description Agostino Sarubbo gentoo-dev 2016-04-11 12:44:07 UTC 
From ${URL} :

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.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

included fix in qemu-2.5.1.  should be fine for stable.
