Summary: Updated openstack-swift packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 5.0. 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 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 OpenStack Object Storage that could allow an authenticated user to delete the most recent version of a versioned object regardless of ownership. To exploit this flaw, an attacker must 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. 4. Solution: Before applying this update, ensure all previously released errata relevant to your system have been applied.
