"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2014:0580 advisory.

    The OpenStack Identity service (keystone) authenticates and authorizes
    OpenStack users by keeping track of users and their permitted activities.
    The Identity service supports multiple forms of authentication including
    user name and password credentials, token-based systems, and AWS-style
    logins.

    The openstack-keystone packages have been upgraded to upstream version
    2013.2.3, which provides a number of bug fixes over the previous version.
    The following security issue is also fixed with this release:

    It was found that the memcached token back end of OpenStack Identity
    did not correctly invalidate a revoked trust token, allowing users with
    revoked tokens to retain access to services they should no longer be able
    to access. Note that only OpenStack Identity setups using the memcached
    back end for tokens were affected. (CVE-2014-2237)

    All openstack-keystone users are advised to upgrade to these updated
    packages, which correct this issue.

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.");
