I was reading an interesting article the otherday concerning a jpeg overflow in the windows OS, since im on a mac, it wouldnt effect me, I took a look, its just an box with an X in it, and didnt seem like much...but it causes the PSP to act strangely...When the system tries to view it, it hangs for a couple of minutes (it eventually displays) Is there anything we can do with this?

**gracz54** · 11-10-2005, 06:46 AM

if it displays it, it cant do anything i think
if it would close than yes
lol i cant even hexedit this thing, keeps getting me access denied

**AzureBlack** · 11-10-2005, 07:06 AM

...what the hell does that mean? Iknow what access denied means, but i've never seen anyone get an access denied message from a jpeg.

**gracz54** · 11-10-2005, 07:27 AM

strange, huh? oh well... too bad

i wont see whats in there

**Calum** · 11-10-2005, 08:41 AM

ofcourse u can :P for every file theres a source

**gracz54** · 11-10-2005, 08:49 AM

well that is the suck, because i dont have anything to compile it with
only have the pspsdk ;/
i would hex the compiled jpg and looked at that

**AzureBlack** · 11-10-2005, 09:01 AM

hmmm...know of any compilers for the mac? I'm sure I could learn it "I would need a little bit of help along the way)

gohan_kvc · 11-10-2005, 09:37 AM

Somebody the a tried with 2.01?

**gracz54** · 11-10-2005, 09:45 AM

on the 2.01 its probably the same as everywhere
i tried it on 1.5, it just sits there for a moment and then displays a empty page with a photo icon in the middle
and when i try to run it the second time, it runs it smoothly the same time when i launch it

**AzureBlack** · 11-10-2005, 10:09 AM

hmmm...so can nothing be done with this then?

**gracz54** · 11-10-2005, 10:17 AM

i dont think there can be something done with that
but i can be wrong

**AzureBlack** · 11-10-2005, 10:26 AM

I had another question, If you replace the icon for an update, does it corrupt the file?

**gracz54** · 11-10-2005, 10:33 AM

you cant replace it with an icon of an update
they are png's, this is a jpg

**AzureBlack** · 11-10-2005, 10:42 AM

nonono, this is somewhat unrelated. I'm just saying if you replace the icon0.png of an update with a different icon, does it get corrupted?

**gracz54** · 11-10-2005, 11:00 AM

yeah, it launches and says that the update is corrupted

**AzureBlack** · 11-10-2005, 11:01 AM

Well im getting offline, going to see the gf, be back later on.

**Ibanez32** · 11-10-2005, 01:38 PM

Well unless it causes a buffer overflow then you won't be able to do much with it.

**AzureBlack** · 11-10-2005, 03:37 PM

I understand that, but there HAS been things such as a png overflow before, meaning the update itslef can be the reason we have an exploit on our hands...but I guess that idea is gone now...wait, Some icons still display in 2.0, most of them actually, is there anyway to use them to our advantage? Does anyone know whether or not you can see the game icons in 2.1 or 2.5?

**TeamOverload** · 11-10-2005, 04:52 PM

you can see the icons in 2.5

i think that someone should try replacing the update png with a regular game png. There is a chance. Not saying it WILL work, but the chances are there.

**TeamOverload** · 11-10-2005, 05:06 PM

i must have missed it, but y does it matter if you change the icon?

*cough*hex edit by sony*cough*

**gracz54** · 11-10-2005, 11:35 PM

if you change the icon, then the update is corrupted when you launch it

**Hmboy** · 11-11-2005, 12:15 AM

They wont make the same mistake twice.. especially regarding 'photo exploits'

**gracz54** · 11-11-2005, 01:43 AM

yeah
so where could we find an exploit? web browser? maybe, but i wouldnt get your hopes up
what else is there?

**Tonite..You_Die** · 11-11-2005, 06:00 PM

the jpeg is a very smal pic of a X ...let ur psp load it...takes about 4 mins then u see it

well they dont seem to have changed anything except libtif so any other possible photo exploits from 2.0 would probably still work, like jpg, gif, or bmp

**makarman** · 11-11-2005, 06:26 PM

Well there is a buffer overflow in PNG and JPG, we just never tried doing anything with them on the PSP.
But the cool thing about a PNG or JPG overflow is that Sony couldn't stop it, since the WipEout browser has its own JPG and PNG libraries.

lolnewb · 11-14-2005, 11:30 PM

y does my antivirus say its a virus?

**pspmad** · 11-15-2005, 01:45 PM

yeah mine frozzy for a cople of seconds and returns to normal well i got to see wht
make the PNG lock up for a couple seconds it is looking for a directory but cant find it
so it just come back from the lock up.......If im wrong then just post

to read file just open in Notepad
