CVE-2016-5362: Openstack Neutron

High severity, CVSS 8.2. EPSS: 3.4% chance of exploitation in the next 30 days.

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.

Affected products

• Openstack Neutron: from 7.0.0, before 7.0.4 (fixed in 7.0.4); from 8.0.0, up to and including 8.1.0
