Claimed vulnerability for embedded systems based on ARM / XScale - Stay tuned!


Reading between the lines it sounds like basically the "vulnerability" is that many devices have JTAG connectors on them, so you can use a hardware debugger to analyze/inject code into most of these devices.  I think it's really only an issue at all (if it even is then) for people with "closed" devices; with something like gumstix, we don't really try to stop people from being able to load their own code onto the thing ;)
