Last month a PS4 Webkit Exploit 2.XX PoC surfaced, and today PlayStation 4 developer qwertyoruiop tweeted news of a PS4 3.50 Webkit Exploit via a heap use-after-free at WebCore::TimerBase::heapPopMin() bug with a proof-of-concept incoming. :)

To quote from PS4BOT on this development: Hey,

I felt i needed to share with you guys as this is going to public.... Which i wasn't really hoping for but ah well. As you can see below Qwerty is about to post heap use-after-free at WebCore::TimerBase::heapPopMin() public. I do currently have the POC but i am not sharing. I guess 3.50 is now going to be the golden firmware hey?

Thanks to @toni1988 in the PSXHAX.COM Shoutbox for the news tip! :cool:

Finally, below is also an Atari Java emulator demo video from an Internet site running on PS4 3.50 from Ryan Henderson for those interested!

On this github I saw 3 files and gave a try on my 2.55 PS4
crash-during-iframe-load-stop.html
resources/crash-during-iframe-load-stop.html
resources/crash-during-iframe-load-stop-inner.html

I had the message "this test passes" meaning that this is not a vulnerability for the (2.55) PS4, no exploitation possible. Maybe vuln. for Iphone but not for the PS4.

We all have to take it easy :)
