Synopsis

Moderate: qemu-kvm-rhev security update

Type/Severity

Security Advisory Moderate

Topic

Updated qemu-kvm-rhev packages that fix two security issues are now available for Red Hat Enterprise Linux OpenStack Platform 4 and 5 for Red Hat Enterprise Linux 6.

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 in environments managed by Red Hat Enterprise Linux OpenStack Platform.

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)

Red Hat would like to thank NSA for reporting these issues.

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
