Description

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 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.
