Description Adam Mariš 2016-04-14 08:52:48 EDT 
Quick Emulator(Qemu) built with the i.MX Fast Ethernet Controller emulator 
support is vulnerable to an infinite loop issue. It could occur while processing
packets on the transmit queue in 'imx_fec_do_tx'.

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