Security Fix(es):

  * An integer overflow flaw and an out-of-bounds read flaw were found in the
way QEMU's VGA emulator set certain VGA registers while in VBE mode. A
privileged guest user could use this flaw to crash the QEMU process
instance. (CVE-2016-3712)

Red Hat would like to thank Zuozhi Fzz (Alibaba Inc.) for reporting this
issue.
