"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2013:0944 advisory.

    Python-keystoneclient is the client library and command line utility for
    interacting with the OpenStack identity API.

    A flaw in Keystone allowed an attacker with access to the web and network
    interfaces of services utilizing python-keystoneclient (such as Nova,
    Cinder, Swift, Glance, and so on) to continue using PKI tokens that had
    expired. This would allow the attacker to continue using the PKI tokens
    despite the PKI tokens being expired, giving them continued access to
    OpenStack services. (CVE-2013-2104)

    This issue was discovered by Eoghan Glynn of Red Hat.

    This update also fixes a number of bugs in python-keystoneclient.

    All users of Red Hat OpenStack 3.0 (Grizzly) Preview are advised to install
    these updated packages.

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.");
