CVE-2016-5362 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.35% chance of exploitation in the next 30 days.
