Covering both bug 1558658 and bug 1502933, here is impact description draft #1.
Is this accurate enough ?

Title: Neutron anti-spoof protection bypass
Reporter: Romain Aviolat (Nagravision) and Dustin Lundquist (Blue Box Group)
Products: Neutron
Affects: >=2015.1.0 <=2015.1.3, >=7.0.0 <=7.0.4, <=8.0.0

Description:
Romain Aviolat from Nagravision and Dustin Lundquist from Blue Box Group, Inc independently reported a vulnerability in Neutron anti-spoof protection. By forging discovery protocol source address, an instance may spoof addresses on attached network resulting in Denial of Service and/or traffic interception. When L2population isn't used, other tenants attached to a shared network are also vulnerable. Neutron setups using the IPTables firewall driver are affected.
