The ld-linux.so bypass *was* really big and trivial. Although it's still possible to do the whole mmap()/mprotect() thing to *still* get an executable, I'd classify it as "some thought and skill required" as opposed to "type this command line". It's not almost-impossible, but I'd rate it a notch above "trivial".... -------------- next part -------------- A non-text attachment was scrubbed...
