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

OpenStack Image Service (glance) provides discovery, registration, and
delivery services for disk and server images. It 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.
A flaw was found in the OpenStack Image Service (glance) import task
action. When processing a malicious qcow2 header, glance could be
tricked into reading an arbitrary file from the glance host. Only
setups using the glance V2 API are affected by this flaw. (CVE-2015-5163)
Red Hat thanks the OpenStack team for reporting this issue. Upstream
acknowledges Eric Harney of Red Hat as the original reporter.
All openstack-glance users are advised to upgrade to these updated
packages, which address this vulnerability.
Before applying this update, ensure all previously released errata relevant
to your system have been applied.
