Confirmed libtiff PSP Exploit
greg | August 22, 2006
I just spotted this in our PSP Hacks forums… 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.

woo hoo this is awesome and YES i am the 1st post
someone at sony just got fired
this is good for users on 2.7 + if it is confirmed working for them still good to see more progress on the hombrew front and eventually everyone will unlock the true power of the psp like those on 1.5
WOW …SWEET..People behind the wheel for me
That’s really cool, hopefully sony havn’t picked up on the vunerability themselves because being able to downgrade 2.8 would be great, especially if that’s how the limited edition PSP’s come
To bad this will mean that the bug will get closed in time for 3.0
a ta-082 and the ability to play homebrew on 2.0 or higher psp this is a brill day for psp homebrew finally all the people can unlokc the potentiol of a 1.5
HE PWNS SONY !!!!!!!1111!1!1
OMG.
Well, thats good but am selling my 1.50 for……$150 want to get my car moving. So good luck, thanks everyone, I hope to hear about you again, no one has ever given me anything for free but you guys did, (you know who you are) thank you.
This would put them down in PSP hacking history if all goes well. :D
OMFG Plese let this come to something,even tho I already have a 1.5,but still I can use my other one for homebrew too.
Wow! there is hope for me at last! of course thanking my son for upgrading it to 2.80 (you little devil) burn in hell! just kidding!!!!
does this mean that you need no longer the umd drive? would be nice because my umd drive is broken and repairing to expensive and send it back to sony no option i hope they find a way for it…:(
that’s good news. my psp is getting dusty on top of my desk since i can’t afford anything (summer = no money :().
and i really really want to play the old gba zeldas at college. that’d be like a dream
can i downgrade my 2.8 psp with this?
Think about it:
Image loader starts eLoader and kernel memory exploit.
Then comes homebrew we never imagined.
So is it already confirmed that Homebrew runs on 2.71, too? And where can I download the files?
vebe, i don’t think it’s got that far. they’ve just found a flaw that could possibly be reversed engineered (or atleast that’s what i made of the brief glimpse i gave the forum post)
Can’t wait till the eyetoy and GPS comes out for the psp (september and november if i rember right.) Say hello 3.0! It’s just an on going war between us and the security updates……Homebrew or tiny camera……….hmmmm
Wow so i dont need the gta umd to play homebrew ?! hope things will go well! V2.01 here
hey 13- try http://www.psptree.co.uk you can get repairs and replacement parts there
im gonna love homebrew once i downgrade my 2.71.
i HOPE i can downgrade my 2.71 lol
me too this is awesome news
@ 20
if you have v2.01 y dont u upgrade to v2.5/6 and just downgrade to 1.5!?!?!?!??!?!
also this will be really cool if it works cuz i got suckerd into upgrading to 2.71 =[
which page should i refresh every second? means: on which page will it stand first if homebrew finally works on 2.71? not on fanjita…
fuckin fresh!
OMFG I SWEAR TO GOD IF YOU FIND A WAY TO DOWNGRADE 2.70 I WILL LOVE WORSHIP YOU. PLEASE PLEASE PLEASE LET THIS COME TO SOMETHING. IF YOU DO FIND ONE I WILL BE SO SO SO SO SO GRATEFUL :)
hahaha. im hopin for a 2.7 downgrade. man its just hilarious how averrage people could outsmart sony
hey hackers i wonder bout your intelligence man its just overwhelming what you can do… RESPECT!!!!!
It has been SUCH A GREAT WEEK - just as good as the 2.6 downloader period, what with the GBA emulator, the TA PSP potential fix, and now news on closer to universal access to homebrew among general 2.7+ users. I’m very happy, and, as always, very grateful (even if I am still having fun on 1.5).
Just going to bed - goodnight everybody.
^Doody.
^*Downgrader
me says that if 2.80 firmware u make homebrew for me will wipe your bottom
what is the best news site for psp h*cking?
omg thats great news but anywa i wont downgrade because i have 2 psp’s one is up to date and the other is 1.5 :) but this will be great for everyone else, i just hope they get a downgrder to 1.0 and that will be awsome why? because u can play any homebrew on it whatsoever and i heard they r working on one so thats great too.
it may not just be a downgrader, as it says, you may not need 1.5 anymore to play homebrew.
and vebe, that is like asking how long is a piece of string. in this instance, the best side for news on it would probably be the developers blog since he’ll post his findings before anyone else.
man, so we may be able to run psp isos thats really cool.Sony will never win.
hope 2.80 gets a exploit
2.7 and hbrew ftw
Massive.Damage.
@23 i dont have a unpatched gta umd
Muhahahaha 2.71 and homebrew.Finally i will have the oppurtinity to play a psp game. No modchips and 1.5s in India. Have been waiting for this for a long long long long time. Whoever is going come out with the exploit…You rock dude…………. Take your own time No hurry!
i really hope this works 4 my 2.60 i don´t have the right versoin of gta lcs my is the pached version but i really wan’t 1.5 agin i never upgraded my 2.60 cuz i waned to have 1.5 agin
1.5-1.52 ore some thing-2.0-2.5-2.6 downloded 2.70 but never installed cuz i wanned 1.5 homebrew agin i miss it so much

Thank you for all your effort! I bought my PsP expecting to be able to use home-brew but can not since it is a 2.8 ! I am extremely disappointed. A £150 paperweight!
I pray u succeed and make sure you put a pay pal donate function on the site you eventually release on.

I have PSP with version 2.6, what i have to download to play games from my memory stick
so… do u guys know when and if the downgrade for 2.8 is coming out? (i downgraded from 2.71 to 1.5 but something happened and i’m still not sure what, but i couldn’t get to the main screen on 2.71, so i was forced to upgrade to sucky version 2.8)
Hoping for the 2.81 downgrade! I love you hackers!
