Podman: Malformed Image can trick podman run into leaking host environment variables into the container

Summary An container image that contains a environment variable with just a key and no value can trick podman into passing that variable from the host into the container. This is made worse by the fact that using an asterisk will cause podman to pass all host variables into the container. So...
