I think, if you realize what you're talking about, the point of the talk was the idea of reliably being able to exploit a IOS vulnerability. Reliably meaning having the cisco box not reboot on you (or other various scenarios that could occur). Gaius has some good information there, but there's a difference between being on a router and plugging in backdoor code and actually being able to get onto the router via an exploit. So what was the key point? CHECK HEAPS -- the idle proc that kicks in to validate heap management structures. Think about malloc() bugs (double free()'s and stuff) that were talked about a few years back... Those were easier to exploit b/c they didn't have a check heaps code that kicks in... If you don't understand the last paragraph, then, please stop trying to post technical arguments on this subject. Cheers, Andrew -- Andrew R.
