Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support
is vulnerable to a divide by zero issue. It could occur while copying VGA
data when cirrus graphics mode was set to be VGA. A privileged user inside
guest could use this flaw to crash the Qemu process instance on the host,
resulting in DoS.
