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,

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.
