Security Fix(es):

* 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 a 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. (CVE-2017-2615)
