Error description

  • Problem Description:
    OpenStack Neutron is vulnerable to a denial of service, caused
    by a flaw in the neutron-openvswitch-agent. By creating two
    security groups with separate/overlapping port ranges, a remote
    authenticated attacker could exploit this vulnerability to
    prevent Neutron from being able to configure networks on any
    compute nodes.
    Impact:
    All Neutron deployments utilizing neutron-openvswitch-agent are
    affected.
