CVE-2016-8667 Qemu: hw: dma: divide by zero error in set_next_tick
Quick Emulator(Qemu) built with the JAZZ RC4030 chipset emulation support is
vulnerable to a divide by zero issue. It could occur while computing its
periodic timer's next tick value.
A privileged guest user could use this flaw to crash the Qemu process instance
on the host resulting in DoS.
