=====================================================================

 

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 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 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.
