CVE-2016-5363 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 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.. EPSS estimates a 3.18% chance of exploitation in the next 30 days.
