[Simon Walter] Re: Bug#506353: mailscanner: many scripts allow local users to overwrite arbitrary files, and more, via symlink attacks

Well if you can even give me a definitive statement of precisely what 
the underlying theoretical problem is, and how to avoid it, that would 
help. I don't want to write a load of code and then discover I've 
misunderstood the underlying problem and not actually fixed anything.

You seem to know all about this problem, or your statements make it 
appear that you do.
