"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2014:1078 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.

    A denial of service flaw was found in Neutron's handling of allowed address
    pairs. There was no enforced quota on the amount of allowed address pairs,
    possibly allowing a sufficiently authorized user to create such a large
    number of firewall rules as to impact performance, or potentially render a
    compute node unusable. (CVE-2014-3555)

    Red Hat would like to thank the OpenStack project for reporting this issue.
    Upstream acknowledges Liping Mao from Cisco as the original reporter.

    All openstack-neutron 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.");
