Red Hat Product Errata RHSA-2014:1187 - Security Advisory
Issued:
2014-09-15
Updated:
2014-09-15

RHSA-2014:1187 - Security Advisory

  • Overview
  • Updated Packages

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

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