Subject: CVE request Qemu: net: mcf_fec: infinite loop while receiving data

   Hello,

Quick Emulator(Qemu) built with the ColdFire Fast Ethernet Controller emulator

receiving packets in 'mcf_fec_receive'.

A privileged user/process inside guest could use this issue to crash the Qemu 
process on the host leading to DoS.
