(RHSA-2014:1187) Moderate: qemu-kvm-rhev security update

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.

Two integer overflow flaws were found in the QEMU block driver for QCOW
version 1 disk images. A user able to supply a malicious image file to QEMU
or to helper tools used in image conversion by services such as Glance and
Nova could potentially use these flaws to cause memory corruption,
resulting in a crash or possibly arbitrary code execution. (CVE-2014-0222,
CVE-2014-0223)

Red Hat would like to thank NSA for reporting these issues.

All users of qemu-kvm-rhev are advised to upgrade to these updated
packages, which contain backported patches to correct these issues. 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.
