If you want to make sure your computer or server is not tricked into undertaking malicious or undesirable behaviour, it's not enough to keep bad code out of the system. Two graduate students from UC San Diego's computer science department - Erik Buchanan and Ryan Roemer - have just published work showing that the process of building bad programs from good code using 'return-oriented programming' can be automated and that this vulnerability applies to RISC computer architectures and not just the x86 architecture (which includes the vast majority of personal computers)...
