3. 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.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
