UBUNTU-CVE-2016-1714

The (1) fwcfgwrite and (2) fwcfgread functions in hw/nvram/fwcfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAPSYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration.
