Security Vulnerability -- An OpenVPN client connecting to a malicious or compromised server could potentially receive "setenv" configuration directives from the server which could cause arbitrary code execution on the client via a LD_PRELOAD attack. A successful attack appears to require 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 configuration file uses a scripting directive such as "up" or "down", (c) the client succesfully authenticates the server, (d) the server is malicious or has been compromised and is under the control of the attacker, and (e) the attacker has at least some level of pre-existing control over files on the client (this might be accomplished by having the server respond to a client web request with a specially crafted file).

Windows reliability changes: * Added code to make sure that the local PATH environmental variable points to the Windows system32 directory. * Added new --ip-win32 adaptive mode which tries 'dynamic' and then fails over to 'netsh' if the DHCP negotiation fails. * Made --ip-win32 adaptive the default.
