Description Prasad Pandit 2017-02-01 09:28:36 UTC 
Quick emulator(Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is
vulnerable to an out-of-bounds access issue. It could occur while copying
VGA data via bitblt copy in backward mode.

A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS OR potentially execute arbitrary code on the host with
privileges of Qemu process on the host.
