                   Red Hat Security Advisory

Synopsis:          Low: openstack-glance security update
Advisory ID:       RHSA-2016:0309-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2016-0309.html

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

1. Summary:

Updated openstack-glance 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 a Low
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 Image Service (glance) provides discovery, registration, and
delivery services for disk and server images. The service provides the
ability to copy or snapshot a server image, and immediately store it away. 
Stored images can be used as a template to get new servers up and running 
quickly and more consistently than installing a server operating system
and individually configuring additional services.

An authorization vulnerability in OpenStack Image service was discovered,
which allowed image-status manipulation using locations. By removing the
last location of an image, an authenticated user could change the status
from 'active' to 'queue'. A malicious tenant could exploit this flaw to 
silently replace owned image data, regardless of its original creator or 
visibility settings. Only environments with show_multiple_locations set
to true (not default) were affected. (CVE-2016-0757)

Red Hat would like to thank the Openstack project for reporting this issue.
Upstream acknowledges Erno Kuvaja of HPE as the original reporter.

All openstack-glance users are advised to upgrade to these updated
packages, which address this vulnerability.

4. Solution:

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