New Exploit Possible? I will be investigating

:D
Hey!
I suspect I found an exploitable loop hole in the internet browser on the PSP.
Therefore, it will allow all PSP's, including the PSP-3000, to have homebrew.
I can't give too much information out publicly, but the exploit involves the Flashplayer and the RSS feeder and URL redirection.
I will be investigating this in my free time.

Alongside this on, I suspect I've found another exploit.
I really haven't said anything about it yet but it's a buffer overflow while rendering JPEG images.
Right now, I have a specially modified JPEG image that returns a random error (garbage) when you try to load it in fullscreen. The thumbnail is perfectly viewable, however.
If I do it corrently, it could lead to the same thing the Tif exploit did.

It's difficult to say.
I haven't analyzed it much because it's difficult to recreate.
It's rare to get it to work and there's many variables effecting how it works so I have to do it precisely the same each time, which is very difficult.
I'll post more news on it when I get more information. I won't give you guys all my notes at one time but I'll feed you guys a little bit of what I discovered a while back.
