Issue date: 2016-01-28
CVE Names: CVE-2016-1714
=====================================================================

1. Summary:

Updated qemu-kvm packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) – i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) – x86_64
Red Hat Enterprise Linux Server (v. 6) – i386, ppc64, x86_64
Red Hat Enterprise Linux Workstation (v. 6) – i386, 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 package provides the
user-space component for running virtual machines using KVM.

An out-of-bounds read/write flaw was discovered in the way QEMU’s Firmware
Configuration device emulation processed certain firmware configurations.
A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the
QEMU process instance or, potentially, execute arbitrary code on the host
with privileges of the QEMU process. (CVE-2016-1714)

Red Hat would like to thank Donghai Zhu of Alibaba for reporting this
issue.

All qemu-kvm users 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.

4. Solution:

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

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):
