Fixed potential local privilege escalation vulnerability in
Windows service. The Windows service did not properly quote the
executable filename passed to CreateService. A local attacker
with write access to the root directory C:\ could create an
executable that would be run with the same privilege level as
the OpenVPN Windows service. However, since non-Administrative
users normally lack write permission on C:\, this vulnerability
is generally not exploitable except on older versions of Windows
(such as Win2K) where the default permissions on C:\ would allow
any user to create files there.
