CVE-2017-18030 Qemu: Out-of-bounds access in cirrus_invalidate_region routine
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 refreshing vnc surface area, in case the initial pitch was negative in cirrus_invalidate_region.
A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS.
