==================================================
  Hello,


Quick Emulator(Qemu) built with the ColdFire Fast Ethernet Controller emulator
support is vulnerable to an infinite loop issue. It could occur while
processing packets on the transmit queue in 'mcf_fec_do_tx'.


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