I still remember geohot's miracle of his limera1n exploit, which was an unpatchable iBoot exploit on iPhone 4. And now we have its successor - axi0mX's checkm8, still an iBoot exploit, still unpatchable. It seems to be another golden age for iOS jailbreaking has came!
Also, just like limera1n, it requires total physical control over the device to run the exploit. A complete, untethered jailbreak still requires additional kernel/userspace exploits, so I don't see it as a major security problem, but it does make the job of an evil maid a bit easier.
Just for nostalgia, here's the original release text of limera1n.
