vulnerability :
- A heap buffer overflow flaw was found in QEMU's Cirrus
CLGD 54xx VGA emulator's VNC display driver support the
issue could occur when a VNC client attempted to update
its display after a VGA operation is performed by a
guest. A privileged user/process inside a guest could
use this flaw to crash the QEMU process or,
potentially, execute arbitrary code on the host with
privileges of the QEMU process. (CVE-2016-9603)
