=====================================================================

1. Summary:

Updated openstack-nova packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno)
for RHEL 7.

Red Hat Product Security has rated this update as having Important
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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux OpenStack Platform 6.0 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.

An information-exposure flaw was found in the OpenStack Compute (nova)
resize and migrate functionality. An authenticated user could write a
malicious qcow header to an ephemeral or root disk, referencing a block
device as a backing file. With a subsequent resize or migration, file
system content on the specified device would be leaked to the user. Only
setups using libvirt with raw storage and "use_cow_images = False" were
affected. (CVE-2016-2140)

This issue was discovered by Matthew Booth of Red Hat.

All openstack-nova users are advised to upgrade to these updated packages,
which correct this issue.

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