Affected packages

• PyPI neutron: < 16.4.1 → fixed in 16.4.1 • PyPI neutron: >= 17.0.0, < 17.1.3 → fixed in 17.1.3 • PyPI neutron: 18.0.0 (no fix yet)

Description

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.
