Topic

Updated qemu-kvm-rhev packages that fix multiple security issues are now
available for Red Hat Enterprise Linux OpenStack Platform 5.0 for Red Hat
Enterprise Linux 7.

Red Hat Product Security 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.

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)

Multiple buffer overflow, input validation, and out-of-bounds write flaws
were found in the way virtio, virtio-net, virtio-scsi, usb, and hpet
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-2013-4149, CVE-2013-4150, CVE-2013-4151, CVE-2013-4527,
CVE-2013-4529, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541, CVE-2013-4542,
CVE-2013-6399, CVE-2014-0182, CVE-2014-3461)

Red Hat would like to thank NSA for reporting CVE-2014-0222 and
CVE-2014-0223. The following issues were discovered by Michael S. Tsirkin,
Anthony Liguori, and Michael Roth of Red Hat: CVE-2013-4148, CVE-2013-4149,
CVE-2013-4150, CVE-2013-4151, CVE-2013-4527, CVE-2013-4529, CVE-2013-4535,
CVE-2013-4536, CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182,
and CVE-2014-3461.

All qemu-kvm-rhev users 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
