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 openstack-swift where an authenticated user may delete the most recent version of a versioned object regardless of ownership. To exploit this flaw an attacker most know the name of the object and have listing access to the x-versions-location container. (CVE-2015-1856)
Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges Clay Gerrard of SwiftStack as the original reporter.
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.
