(RHSA-2014:1338) Moderate: openstack-glance security and bug fix 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 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)

This update also fixes the following bugs:

• Whenever the ‘x-image-meta-store’ header was passed to glance-api, the
  service would check whether the value was a valid store instead of a valid
  scheme. However, the rest of the store library uses the scheme to identify
  the store that should be used; this prevented the use of this feature.
  Glance now verifies that the value of ‘x-image-meta-store’ is a valid
  scheme instead of a valid store name. (BZ#1134249)

• With this update, Image Service (glance) is now dependent on oslo.vmware
  in order to support the optional VMware store. This hard dependency was
  created due to the likelihood that the dependencies are already installed
  and due to the diminutive size of the package. As a result, the user
  experience is improved by no longer requiring a manual oslo.vmware
  install. (BZ#1125876)

• Previously, the process of upgrading from Red Hat Enterprise Linux
  OpenStack Platform 4 to 5 may have failed. (BZ#1139243)

All openstack-glance users are advised to upgrade to these updated
packages, which correct these issues.
