Hendrik Weimer discovered that OpenVPN, the Virtual Private Network
daemon, allows to push environment variables to a client allowing a
malicious VPN server to take over connected clients.

the old stable distribution (woody) does not contain openvpn packages.

For the stable distribution (sarge) this problem has been fixed in
