Possible exploit in pictures and video?

Even if you manage to crash the system with this, you wont get any unsigned code running - on newer systems like the ps3 this isnt possible

I agree.

But just for theoretical sake, what if you manipulated the hex values to crash and boot straight to recovery mode on say a 3.41 ps3, with a dongle holding a signed pup plugged in, containing a cfw update with keys. Then it will work as the system is still holding the previous data values until it is killed.

Yes, I already no about the key situation, it's just theoretical. It's not such a stupid idea, it just won't happen.

Now, if we could use a hyperterm kill signal leaving the ports open, you could reinvent the wheel using the same hardware with endless possibilities. This would take lots of time and effort but would be easier than flashing a modem once the software was written. If Sony can change the software through an inbound connection then there is a loophole to exploit and poke.

you never know anything is possible nowadays besides im tired of repeating that it worked on psp so ... why not!

yeah and everyone knows the ps3 is just a more powerful psp [/off]

Just because you find an expolit in pics or videos doesn't mean it'll be a "kernel mode exploit."

[DangKid]

It worked with the iPhone and iPod Touches with the .pdf exploit. See "jailbreakme.com"

If you can invoke it through hyperterm it would be aimed at a tsop or similar, to dump and write. ( replace the kernel )

Christ if the PSP had an a tiff exploit do you think Sony would leave it in another product of theirs?
Didn't it occur to you that they fixed it in future PSP fws?

key words being future PSP FWS not ps3 lol and i thinbk it is very possible in older phat models which i dont posses but we will still see some progress even its in the older models if im not mistaken i believe that the tiff exploit was patched in newer models of psps like the ti-804's

What he is trying to point out is that an image file such as a jpg, bmp or better yet a png, actually holds data other than that of the image. It can hold values and orientation detail all of wich can be in a hexcidecimal, octal and binary format and therefore can be manipulated. If a loophole can be found to crash, freeze and exploit the hardware it is more than possible however very unlikely. This is not a stupid concept just outdated and very unlikely that Sony would be so stupid to leave such a hole to poke.

Well done for the thought....,

lol

this is old old old.

People looked into this when the ps3 first came out 3-4 years ago. Duhhh it's where the PSP was first hacked. Give the hackers credit for not being total plonkers.

[robo989]

We are the stupid people, we don't come up with fantastic concepts that a proper hacker hasn't thought of before.

End of story.
