Topic

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

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.

A heap buffer overflow flaw was found in the way QEMU's NE2000 NIC
emulation implementation handled certain packets received over the
network. A privileged user inside a guest could use this flaw to crash the
QEMU instance (denial of service) or potentially execute arbitrary code on
the host. (CVE-2015-5279)

Red Hat would like to thank Qinghao Tang of QIHU 360 Inc. for reporting
this issue.

All users of qemu-kvm-rhev are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue. After
installing this update, shut down and restart all running virtual machines
for this update to take effect.

Solution

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