"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2014:1942 advisory.

    OpenStack Networking (neutron) is a pluggable, scalable, and API-driven
    system that provisions networking services to virtual machines. Its main
    function is to manage connectivity to and from virtual machines. As of Red
    Hat Enterprise Linux OpenStack Platform 4.0, 'neutron' replaces 'quantum'
    as the core component of OpenStack Networking.

    A denial of service flaw was found in the way neutron handled the
    'dns_nameservers' parameter. By providing specially crafted
    'dns_nameservers' values, an authenticated user could use this flaw to
    crash the neutron service. (CVE-2014-7821)

    Red Hat would like to thank the OpenStack project for reporting this issue.
    Upstream acknowledges Henry Yamauchi, Charles Neill, and Michael Xin
    (Rackspace) as the original reporters.

    This update also fixes the following bugs:

    * Prior to this update, the network name and UUID were not sent to N1KV
    during the subnet creation process. Consequently, N1KV was unable to
    properly associate the network and subnet in its local configuration.
    This update addresses this issue by sending the required network name and
    UUID during subnet creation, with the result that they are now properly
    associated on the N1KV. (BZ#1118508)

    * Previously, a rollback did not result in all entries being cleared from
    the N1KV-specific database tables, resulting in the presence of stale
    entries. This update addresses the issue by performing a proper cleanup of
    all N1KV tables. Consequently, stale entries are no longer left in the N1KV
    tables. (BZ#1124991)

    * Previously, the N1KV OpenStack Networking (neutron) plug-in did not sent
    the subtype for overlay networks during the network segment pool creation
    process. This update addresses this issue by sending the required details
    during the creation process. (BZ#1130336)

    All openstack-neutron users are advised to upgrade to these updated
    packages, which contain backported patches to correct these issues.

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.");
