Summary

OpenStack Image Service (glance) provides discovery, registration, and delivery services for disk and server images. The service 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.
An authorization vulnerability in OpenStack Image service was discovered, which allowed image-status manipulation using locations. By removing the last location of an image, an authenticated user could change the status from 'active' to 'queue'. A malicious tenant could exploit this flaw to silently replace owned image data, regardless of its original creator or visibility settings. Only environments with show_multiple_locations set to true (not default) were affected. (CVE-2016-0757)
Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges Erno Kuvaja of HPE as the original reporter.
All openstack-glance users are advised to upgrade to these updated packages, which address this vulnerability.
