Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Docker Engine (github.com/docker/docker, Moby dockerd) versions 1.12.0 through 20.10.23 and 23.0.0 through 23.0.2 are affected. An attacker with network access to a node can send unencrypted VXLAN packets tagged with an encrypted overlay network's VNI, injecting arbitrary Ethernet frames into that network when it has only a single endpoint. Upgrade to 20.10.24 or 23.0.3; Mirantis Container Runtime users should update to 20.10.16.
