CVE-2016-5362

Estado: ModificadaAlta (8.2)—

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 DHCP-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via a crafted DHCP discovery message.
