Moderate: openstack-glance security and bug fix update
Security Advisory: Moderate
Updated openstack-glance packages that fix two security issues and several
bugs are now available for Red Hat Enterprise Linux OpenStack Platform 6.0.
Red Hat Product Security has rated this update as having Moderate 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.
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.
Multiple flaws were found in the glance task API that could cause untracked
image data to be left in the back end. A malicious user could use these
flaws to deliberately accumulate untracked image data, and cause a denial
of service via resource exhaustion. (CVE-2014-9684, CVE-2015-1881)
The openstack-glance packages have been upgraded to upstream version
2014.2.3, which provides a number of bug fixes over the previous version.
All openstack-glance users are advised to upgrade to these updated
packages, which correct these issues.
Before applying this update, ensure all previously released errata relevant
to your system have been applied.
