Overview:

So what is a buffer overrun and why should you care? The SANS institute a few months back released a list of the 10 most commonly used methods to break into servers. Of these ten a large number can be attributed to buffer overrun vulnerabilities. They are a major problem. This is why you should know about them. So what are they then? A buffer overrun occurs when a program sets aside, say, 100 bytes of memory to hold some data, (this is the buffer), but then the user tries to stuff in 200 bytes of input, and like someone attempting to pour a pint of milk into a glass that'll only hold half a pint, the remainder will overflow.
