Topic

Updated openstack-swift packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 6.0.

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.

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-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.
