However, even if tools like file/ndisasm/gimp/readelf can be used by many (w/o strong system isolation boundaries) to analyze untrusted inputs (for reverse engineering, malware analysis and similar purposes) - I'd simply put a blame on those usersWell, it's always the easy option, but keep in mind that there are countless tutorials that tell people to use 'file' or 'strings' to examine sketchy file, or use tools such as objdump to do hobby forensics. We can blame the authors of the tutorials - but it goes back to a fairly fundamental problem: the use cases aren't completely crazy (nothing *fundamentally* wrong in using 'strings' on a file you don't trust, right?), and their unsafe design is a fairly counterintuitive property to laypeople and many experts alike [*]. So, for high-profile tools used in ways that are sort of plausible and probably common, we may just need to try & make them robust.
Agreed.
(But of course, I'd be pragmatic in drawing the line: the Mayhem fuzzing thing went completely overboard.)
