rh#1336429

Quick Emulator(Qemu) built with the VMware-SVGA "chipset" emulation support is vulnerable to an information disclosure issue. It could occur while processing VGA commands via its FIFO buffer.

A privileged user inside guest could use this flaw to leak host memory bytes or crash the Qemu process resulting in DoS.
