1. Summary:

 

Updated qemu-kvm-rhev packages that fix several security issues are now

available for Red Hat Enterprise Linux OpenStack Platform 3.0 and 4.0.

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux OpenStack Platform 3.0 - x86_64

Red Hat Enterprise Linux OpenStack Platform 4.0 - x86_64

 

3. 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.

 

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)

 

These issues were discovered by Michael S. Tsirkin, Anthony Liguori and

Michael Roth of Red Hat: 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.

 

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.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
