The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended MAC-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via (1) a crafted DHCP discovery message or (2) crafted non-IP traffic.

Neutron functionality includes internal firewall management between networks. Due to the relaxed nature of particular rules, it is possible for machines on the same layer 2 networks to forge non-IP traffic, such as ARP and DHCP requests.

CVE-2016-5363 openstack-neutron: MAC source address spoofing vulnerability

CVE-2016-5363 [HIGH] CVE-2016-5363 openstack-neutron: MAC source address spoofing vulnerability
CVE-2016-5363 openstack-neutron: MAC source address spoofing vulnerability
A vulnerability 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.
