Topic

Updated qemu-kvm-rhev packages that fix several security issues are now
available for Red Hat Enterprise Virtualization.

The Red Hat Security Response Team has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

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 Virtualization Manager.

Multiple buffer overflow, input validation, and out-of-bounds write flaws
were found in the way the virtio, virtio-net, virtio-scsi, and usb drivers
of QEMU handled state loading after migration. A user able to alter the
savevm data (either on the disk or over the wire during migration) could
use either of these flaws to corrupt QEMU process memory on the
(destination) host, which could potentially result in arbitrary code
execution on the host with the privileges of the QEMU process.
(CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541,
CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, CVE-2014-3461)

An out-of-bounds memory access flaw was found in the way QEMU's IDE device
driver handled the execution of SMART EXECUTE OFFLINE commands.
A privileged guest user could use this flaw to corrupt QEMU process memory
on the host, which could potentially result in arbitrary code execution on
the host with the privileges of the QEMU process. (CVE-2014-2894)

The CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536,
CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, and
CVE-2014-3461 issues were discovered by Michael S. Tsirkin of Red Hat,
Anthony Liguori, and Michael Roth.

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.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
