Skylark and psp250, along with a dedicated
team of developers & hackers, have been researching the possibility
of using the same exploitable libtiff vulnerability initially
discovered by NOPx86. This may potentially result in a GTA-less method
to execute homebrew on 2.01 or higher, or conceivably open up the
homebrew gates for 2.71/2.80; however, that’s yet to be confirmed.
Nonetheless, with all the latest developments surrounding 2.0+ FW and
TA-082, there’s a good possibility something will become available
rather sooner than later - big things are brewin’, you feel it?!
The Fanjita Facts:
Alright, time for a brief update with the facts so far.
This exploit is definitely genuine, and usable.
It’s
unclear exactly which firmwares it will be usable on, but so far 2.0
and 2.01 should definitely work. 2.5 and above are significantly harder
to research. 2.7+ will take longer still. The signs are that it may go
up as far as 2.8, but that’s not proven.
Just to put things
into perspective, a combined team has spent at least 60 intensive hours
working on researching this so far, and we’re at the point of being
able to confirm that it will work.
It will take longer still to convert it into something that is actually in a demonstrable form, such as Hello World.
Credit
so far goes to NOPx86 for discovering the vulnerability and proof of
concept on the PC, and Skylark and psp250 for researching it on the
PSP. I’ve helped a bit too, but those guys have done the bulk of the
work.
