Reporter: Darragh O'Reilly (HP)
Products: Neutron
Affects: 2014.2 versions through 2014.2.3 and 2015.1.0 version

Description:
Darragh O'Reilly from HP reported a vulnerability in Neutron. By adding
an address pair which is rejected as invalid by the ipset tool, an
authenticated user may crash the Neutron L2 agent resulting in a denial
of service attack. Neutron setups using the IPTables firewall driver are
affected.
