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.
