in reply to Security with open() in CGI scripts

Another great resource that covers CGI/Web programming security basics is Ovid's online CGI programming course, particularly lesson #3, Basic Security with CGI.pm. It has great information about untainting your data, including that naughty NULL byte.

I learned tons from reading this quick and condensed course.
