The author mentions that this bug saved him 1000s of hours in development. How is a sandbox escape useful in development? Can someone give me an example?
If you're looking for 0day kernel exploits that might be popped from say MobileSafari, having an unrestricted, unsandboxed non-root shell is a much better starting point compared to a regular sandboxed app launched from xcode. Or even just for inspecting the filesystem outside a regular app's restricted container.
