RHEL 7 : openstack-swift (RHSA-2015:1681)

Synopsis

The remote Red Hat host is missing a security update for openstack-swift.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:1681 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL openstack-swift package based on the guidance in RHSA-2015:1681.
