Description

KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the
user-space component for running virtual machines using KVM, in
environments managed by Red Hat Enterprise Linux OpenStack Platform.

It was found that the Cirrus blit region checks were insufficient.
A privileged guest user could use this flaw to write outside of
VRAM-allocated buffer boundaries in the host's QEMU process address space
with attacker-provided data. (CVE-2014-8106)

This issue was discovered by Paolo Bonzini of Red Hat.

All users of qemu-kvm-rhev are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue. After
installing this update, shut down all running virtual machines. Once all
virtual machines have shut down, start them again for this update to take
effect.
