Summary

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.
