Description Victor Pereira 2016-09-13 06:23:14 UTC 
rh#1374702

Quick Emulator(Qemu) built with the VMware-SVGA "chipset" emulation support
is vulnerable to an OOB stack memory write issue. It could occur while
processing VGA commands in 'vmsvga_fifo_run' routine.

A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS.
