Description

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.
