            Hello,
    
    I don't know if this was posted before, please accept my appologies if so.
      Seems like the guys at XiG forgot the meaning of /tmp security ...
      The main problem is that the Install program of the AcceleratedX package
    logs all in a file named /tmp/Install.log. So, every user knowing that
    Mr ReWT is going to install this X server on his box can overwrite any
    file on the system.
      The procedure is very simple: ln -s /etc/shadow /tmp/Install.log
      Oh, some of you may tell me : "What if AcceleratedX is already
    installed?". There is also an Uninstall.log =->
      I think the /tmp/Xaccel.ini is also the temporary file for new
    configurations, so wait for the root to change something and KAB00M! :))
      I am too lazy to cc this to the guys at XiG so please do it if you want.
