NVD Description

Note: Versions mentioned in the description apply only to the upstream neutron package and not the neutron package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

OpenStack Neutron before 16.4.1, 17.x before 17.1.3, and 18.0.0 allows hardware address impersonation when the linuxbridge driver with ebtables-nft is used on a Netfilter-based platform. By sending carefully crafted packets, anyone in control of a server instance connected to the virtual switch can impersonate the hardware addresses of other systems on the network, resulting in denial of service or in some cases possibly interception of traffic intended for other destinations.
