and 7.0 for Red Hat Enterprise Linux 7.

 

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 OpenStack Platform 5.0 for RHEL 7 - noarch

Red Hat Enterprise Linux OpenStack Platform 6.0 for RHEL 7 - noarch

Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - noarch

 

3. Description:

 

OpenStack Compute (nova) launches and schedules large networks of virtual

machines, creating a redundant and scalable cloud computing platform.

Compute provides the software, control panels, and APIs required to

orchestrate a cloud, including running virtual machine instances and

controlling access through users and projects.

 

A flaw was discovered in the OpenStack Compute (nova) snapshot feature when

using the libvirt driver. A compute user could overwrite an attached

instance disk with a malicious header specifying a backing file, and then

request a snapshot, causing a file from the compute host to be leaked. This

flaw only affects LVM or Ceph setups, or setups using filesystem storage

with "use_cow_images = False". (CVE-2015-7548)

 

This issue was discovered by Matthew Booth of Red Hat OpenStack

Engineering.

 

All openstack-nova users are advised to upgrade to these updated packages,

which correct this issue.

 

4. Solution:
