From http://www.openwall.com/lists/oss-security/2015/09/15/2:

Qemu emulator built with the NE2000 NIC emulation support is vulnerable to an 
infinite loop issue. It could occur when receiving packets over the network.

A privileged user inside guest could use this flaw to crash the Qemu instance 
resulting in DoS.

Upstream fix:

@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.

qemu-2.4.0.1 in the tree should have the fixes for this and should be fine to mark stable
