An OpenVPN client connecting to a malicious or compromised server could potentially receive an "lladdr" or "iproute" configuration directive from the server which could cause arbitrary code execution on the client. A successful attack requires that (a) the client has agreed to allow the server to push configuration directives to it by including "pull" or the macro "client" in its configuration file, (b) the client succesfully authenticates the server, (c) the server is malicious or has been compromised and is under the control of the attacker, and (d) the client is running a non-Windows OS.
