RHSA-2013:1525 - Security Advisory

Topic

Updated openstack-glance packages that fix one security issue and several
bugs are now available for Red Hat OpenStack 3.0.

The Red Hat Security Response Team has rated this update as having moderate
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.

Description

The openstack-glance packages provide a service (code name Glance) that
acts as a registry for virtual machine images.

A flaw was found in the Glance download_image policy enforcement for cached
system images. When an image was previously cached by an authorized
download, any authenticated user able to determine the image by its UUID
could download that image, bypassing the download_image policy. Only setups
making use of the download_image policy were affected. (CVE-2013-4428)

Red Hat would like to thank the OpenStack Project for reporting this
issue. The OpenStack Project acknowledges Stuart McLaren from HP as the
original reporter.

These updated openstack-glance packages have been upgraded to upstream
version 2013.1.4, which provides a number of bug fixes over the previous
version. (BZ#1021640)

All users of openstack-glance are advised to upgrade to these updated
packages, which correct these issues. After installing the updated
packages, the running Glance services must be manually restarted (using
"service [service name] restart") for this update to take effect.
