in reply to Untainting system calls correctly

As a security measure, I think taint is a little beside the point if you are handing out shell accounts via a web form.

Please say you have some layers of approval, authorization and authentication above this! :)

    Not really shell accounts. If you notice the shell is set to /bin/false. Plus the script is only available to clients that have signed off on a lengthy contract agreement. To boot, its available through a strictly ssl connection that requires user/pass authorization.

    There are additional checks within the script to restrict touching UID less than 500, passing a group to a GID that is greater than 500.

    I know that there are plenty of issues that still need to be addressed, but I was just curious to see exactly *why* i am seeing it fail in my current situation.

    thanks -c
