CVE Names: CVE-2014-7960
=====================================================================

1. Summary:

Updated openstack-swift packages that fix one security issue 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 Object Storage (swift) provides object storage in virtual
containers, which allows users to store and retrieve files (arbitrary
data). The service's distributed architecture supports horizontal scaling;
redundancy as failure-proofing is provided through software-based data
replication. Because Object Storage supports asynchronous eventual
consistency replication, it is well suited to multiple data-center
deployment.

A flaw was found in the metadata constraints in OpenStack Object Storage
(swift). By adding metadata in several separate calls, a malicious user
could bypass the max_meta_count constraint, and store more metadata than
allowed by the configuration. (CVE-2014-7960)

All users of openstack-swift are advised to upgrade to these updated
packages, which correct this issue. After installing this update, the
OpenStack Object Storage services will be restarted automatically.
