    Synopsis:          Moderate: openstack-glance security and bug fix update
    Advisory ID:       RHSA-2014:1337-01
    Product:           Red Hat Enterprise Linux OpenStack Platform
    Advisory URL:
    Issue date:        2014-09-30
    CVE Names:         CVE-2014-5356 
    1. Summary:
    Updated openstack-glance packages that fix one security issue and two bugs
    are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 for
    Red Hat Enterprise Linux 7.
    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 7 - 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:
    * Uploading an image to glance that exceeded the user's current quota
    setting was rejected, but no message was added to the glance API log to
    indicate this. This update fixes this bug, and such events are now logged
    as INFO messages in the glance API log. (BZ#1055550)
    * 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#1130622)
    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.
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    5. Bugs fixed (
    1055550 - glance: no error reported in api.log when image create is killed on quota
    1130622 - Glance `--store` checks on store name instead of scheme
    1131770 - CVE-2014-5356 openstack-glance: Glance store disk space exhaustion
