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.

https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg02577.html

Use CVE-2016-8667.

This is not yet available at
http://git.qemu.org/?p=qemu.git;a=history;f=hw/dma/rc4030.c but
that may be an expected place for a later update.
