(RHSA-2015:0246) Important: openstack-glance security update

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 an authenticated user could use a path traversal
flaw in glance to download or delete any file on the glance server that is
accessible to the glance process user. Note that only setups using the
OpenStack Image V2 API were affected by this flaw. (CVE-2014-9493)

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.
