The problem of buffer overflows is an excellent argument for using other programming languages such as Perl, Python, Java, and Ada95. After all, nearly all other programming languages used today (other than assembly language) protect against buffer overflows. Using those other languages does not eliminate all problems, of course; in particular see the discussion in Section 8.3 regarding the NIL character. There is also the problem of ensuring that those other languages' infrastructure (e.g., run-time library) is available and secured. Still, you should certainly consider using other programming languages when developing secure programs to protect against buffer overflows.
