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!
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!
