Topic

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.

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.

Before applying this update, make sure all previously released errata
