It works!

DO NOT CLICK THE LINK! Hour later I am still unable to restart my phone. It hangs on logo!! This may be a permanent fuck ;( unsure exact version but I have iOS 7 that hasnt been updated in about six months.

DO NOT CLICK THE LINK!

Never imagined I'd read those words at HN. How times have changed. Be sensible people.

try a force restart (home + power button for about 10 seconds)

What is home?

The tweet announcing it: https://twitter.com/pwnsdx/status/1040944750973595649 The code that causes the crash (safe to open): https://gist.github.com/pwnsdx/ce64de2760996a6c432f06d612e33... The demo itself (causes crash): https://cdn.rawgit.com/pwnsdx/ce64de2760996a6c432f06d612e33a...

It works!

I have always wondered why Safari crashes can reboot the entire telephone. Doesn't iOS have multiple protection rings or is Safari running at ring 0? Or is it a precaution that inhibits jailbreak research?

Same here, I thought it was completely sandb0xed

Seems like on restart Safari wants to revisit previously opened pages and crashes again ad infinitum. Isn't there a way to cold-restart iOS devices or some such (like the magic "Zap NVRAM and repair permissions" procedure back in PowerMac times)?

"Seems like on restart Safari wants to revisit previously opened pages"

I've always found that behavior annoying. If I want to revisit the last page, I can find it in history.
