Original post by Fidelcastro : viewtopic.php?f=33&t=2764



At first, the name its just for reference, if you have any suggestion, go ahead and tell me ;)

Since a while, i have been working on PNG and BITMAP images. As you may think, we are looking for exploits that can help to

liberate cursed mainboards, on firmwares higher to 5.03.

All this time,i've been helped and adviced by m0skit0, wich i want to thank for all his patience and knowledge :adora:.

I've been trying to get to a buffer overflow on png images,but just got a "Low System Memory", an overflow without a crash with no use at all.

My idea is : I would like, that all people on the forum, will help on this,forming a team of developers (anyone trying to help, is welcomed ;) ),and a betatesters team for testing this files on OFW higher than 5.03.

If you want to join the project, you need to know this is a serious bussiness, you know the forum rules, and i will add some new rules to this post, for everything to go well:

*This is "PSP" , so, stop the off-topic discussions.
*All the images treated here, will become Forum property.
*Every image will be uploaded in zip, and using the filebox .

Now i will post some links for investigation , and some images for buffer overflow, so you can work on them.As you know, Wikipedia is your friend :)

Formats:

PNG
PNG wiki link
LIBPNG PNG official homepage

Bitmap
BMP wiki link
Bitmap format wiki link

Tiff
Tiff wiki link
LibTiff tiff official homepage

Well, as this,any other media file that the psp can play are admitted, but i advice you to take just one kind of file, or you will get crazy, as you wish :)

Test 1 PNG
Test 2 PNG
Test 3 PNG
Test 4 PNG
tiff01

Last Ones

Download: fidelmp4
Download: fidelmp3

Without more, and expecting your support to the project, Good luck :oki:

Hi together

I have downloaded the mp3 and the mp4.
So my Questions/Tests with it.

mp3:
When i test the mp3 on my psp GO (5.70) i can't even open the folder to display the mp3 on my psp. -> Exception or Breakpoint (PSP Go shutdown like other errors)
I test the mp3 on my psp 2004 (5.50g) with psplink. I can see the mp3 file on the psp and run it. After i start it -> Exception - Syscall (like Fidel Castro)
Is this normal that the way of the Exception or Breakpoint can be different on each firmware? (Maybe i should try the mp3 with 6.20 on my psp 2004)

mp4:
When i play it (Press "X") and want to end it (Press "O"), my psp go gets strange -> I can't push any key. The only thing i can do, is shutdown the psp by holding the off switch until all leds are flashing one time. (I have wait for 2-3 mins do nothing -> the psp don't shut it self down).
The same on my psp 2004 with (5.50g). The problem is that i have no output on the psplink panel for this "crash". (Only get the command "loaded all moduls.." from start up)
Is this strange or normal?

best regards
Snake

PS. Sorry for bad English. Prefer an other. ^^

Hi Snake, glad you decided to post here :oki:

Snake escribió:Is this normal that the way of the Exception or Breakpoint can be different on each firmware? (Maybe i should try the mp3 with 6.20 on my psp 2004)

Yes it is because MP3 library and VSH software are not the same. And just FYI a breakpoint is a type of exception.

Snake escribió:The problem is that i have no output on the psplink panel for this "crash". (Only get the command "loaded all moduls.." from start up)

It's normal, but no crash means no way to easily know what's happening behind the scenes, thus hardly exploitable.
