Summary

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.
It was discovered that the image_size_cap configuration option in glance was not honored. An authenticated user could use this flaw to upload an image to glance and consume all available storage space, resulting in a denial of service. (CVE-2014-5356)
The openstack-glance packages have been upgraded to upstream version 2013.2.4, which provides a number of bug fixes over the previous version. (BZ#1146089)
All openstack-glance users are advised to upgrade to these updated packages, which correct these issues. After installing the updated packages, the running glance services will be restarted automatically.
