"The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced
in the RHSA-2015:1684 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 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.

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.");
