libtiff Vulnerability gives hope for a new GTA-less PSP Exploit!

straight from QJ.net.

PSP ExploitOur PSP forums have been abuzz lately with the talk of a possible new exploit centered around a libtiff vulnerability. Discussion started in our Developer's Dungeon when a message was relayed from NOPx86 stating that he'd managed to crash the PSP using this method. As those of you who follow these things know, a crash doesn't always mean an open door to an exploit.

But after a $#@!ulative 60 hours of work and research put in by Skylark and psp250 (with a little help from Fanjita), they can confirm that NOPx86's method is indeed valid and opens the door for a new exploit. They have confirmed that it will work on 2.0 and 2.01 PSP's, and could potentially work on firmware as high as 2.80 - although at this moment, this is unconfirmed.

But even if this only works on lower firmwares, it will usher in the age of GTA-less homebrew for 2.01+ PSP's, which will be a welcome change for homebrew enthusiasts.

Work and research on applying this exploit into a publicly usable form will take some time, and it will take even more time to put this to use on PSP's with higher firmware, but there definitely are possibilities. As always, we'll keep you up to date on this developing story as soon as more information becomes available.

Feel free to check out the two topics on our forums discussing this latest breakthrough - please note that while the Developer Dungeon can be read by all registered users, only developers may post there so they can work without user interruption.
