KVM (for Kernel-based Virtual Machine) is a full virtualization solution for
Linux on x86 hardware. Using KVM, one can run multiple virtual machines running
unmodified Linux or Windows images. Each virtual machine has private virtualized
hardware: a network card, disk, graphics adapter, etc.
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.
