|CVE:||CVE-2016-5362 (DHCP spoofing), CVE-2016-5363 (MAC source address spoofing), CVE-2015-8914 (ICMPv6 source address spoofing)|
Romain Aviolat from Nagravision and Dustin Lundquist from Blue Box Group, Inc independently reported vulnerabilities in Neutron anti- spoof protection. By forging DHCP discovery messages or non-IP traffic, such as ARP or ICMPv6, an instance may spoof IP or MAC source addresses on attached networks resulting in denial of services and/or traffic interception. Moreover when L2population isn’t used, other tenants attached to a shared network are also vulnerable. Neutron setups using the IPTables firewall driver are affected.
