Synopsis:          Moderate: openstack-glance security and bug fix update
Advisory ID:       RHSA-2014:1338-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1338.html
Issue date:        2014-09-30
CVE Names:         CVE-2014-5356 
=====================================================================

1. Summary:

Updated openstack-glance packages that fix one security issue and three
bugs are now available for Red Hat Enterprise Linux OpenStack Platform 5.0
for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 6 - noarch

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

5. Bugs fixed (https://bugzilla.redhat.com/):

1125876 - openstack-glance should depend on python-oslo-vmware
1131770 - CVE-2014-5356 openstack-glance: Glance store disk space exhaustion
1134249 - Glance `--store` checks on store name instead of scheme
1139243 - RHOS4->RHOS5 upgrade fails due to wrong version of python-migrate installed
