"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2013:1285 advisory.

    The openstack-keystone packages provide Keystone, a Python implementation
    of the OpenStack identity service API, which provides Identity, Token,
    Catalog, and Policy services.

    It was found that Keystone did not correctly handle revoked PKI tokens,
    allowing users with revoked tokens to retain access to resources they
    should no longer be able to access. This issue only affected systems using
    PKI tokens with the memcache or KVS token back ends. (CVE-2013-4294)

    Red Hat would like to thank Thierry Carrez of OpenStack upstream for
    reporting this issue. Upstream acknowledges Kieran Spear of University of
    Melbourne as the original reporter.

    All users of openstack-keystone are advised to upgrade to these updated
    packages, which correct these issues. After installing the updated
    packages, the Keystone service (openstack-keystone) 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.");
