CVE request Qemu: net: eepro100 memory leakage at device unplug

[P J P <ppandit () redhat com>]

  Hello,

Quick Emulator(Qemu) built with the i8255x (PRO100) NIC emulation support is 
vulnerable to a memory leakage issue. It could occur while unplugging the 
device, and doing so repeatedly would result in leaking host memory affecting, 
other services on the host.

A privileged user inside guest could use this flaw to cause a DoS on the host 
and/or potentially crash the Qemu process on the host.
