This issue is due to a failure of the application to securely parse the
saved port number of the last authentication store in windows register. 

To reproduce this, we have to modify the default register key of
HKEY_CURRENT_USER\Software\Novell\GroupWise\Login Parameters\TCP/IP Port 

This is obviously a bug, but why is this a security vulnerability?
Does the GroupWise client run with elevated privileges?
