CVE-2016-1981

QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is
vulnerable to an infinite loop issue. It could occur while processing data
via transmit or receive descriptors, provided the initial receive/transmit
descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A
privileged user inside guest could use this flaw to crash the QEMU instance
resulting in DoS.
