Security Fix(es):



* An out-of-bounds memory access issue was found in Quick Emulator (QEMU)

in the VNC display driver. This flaw could occur while refreshing the VNC

display surface area in the 'vnc_refresh_server_surface'. A user inside a

guest could use this flaw to crash the QEMU process. (CVE-2017-2633)
