    Summary: OpenStack Neutron Intended MAC-spoofing protection mechanism bypass

    Details: The IPTables firewall in OpenStack Neutron up to 7.0.4 and 8.x before 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.
