Slashdot | Gosling Claims Huge Security Hole in .NET:

As much as I think his presentation method is tacky, I can agree with some of what he says.

C and C++ allow for buffer overflows. They allow for improper or intentional coding to cause software to try to violate memory space of other functions or programs. They allow for memory allocation without necessarily providing any cleanup later. In the hands of bad, sloppy, lazy, or malicious programmers these traits have always proven to be a problem time and again on many different platforms. This doesn't mean that these languages are the wrong tool; I'd argue that part of Linux's success is because the kernel and most of the GNU-implemented services are written in these languages, which are flexible. Too much flexibility for the wrong purpose leads to problems though, just as too much rigidity leads to problems when things need to be flexible.
