Buffer Overflow Found in PSP Firmware v2.0

Posted by Zonk on from the toys- dept.

Doomstalk writes "PSP news site PSP Updates is reporting that a buffer overflow flaw has been found in PSP firmware v2.0's photo viewer. So far it's only been used to corrupt the menu display, but it holds great promise for running homebrew code on upgraded PSPs." From the article: "Thanks to the unknown author(s) for this great starting point to have homebrew on 2.0, all that is needed are coders to extend this knowledge for full homebrew usage on the v2.0 firmware. We cannot say when someone will step up to the plate and write the code for users to run homebrew on a 2.0 using this exploit, but we will definitely have our ears (and email boxes) open and be sure to let you know as soon as we do."

  1. The Real Emulation Console is Coming by Anonymous Coward · · Score: 5, Informative

    The PSP and this rather lame exploit which only lets you run up to 64kb which to those who dont know isnt enough to run 99% of homebrew and emulators, yes it creates news but its not going anywhere, thank god the new Portable Linux Console that embraces Open Source Coding has arrived, Emulation and Homebrew with out stupid little exploits, yes im talking about the GP2X http://www.gbax.com/main.pl Once it arrives we can say hello to the future of amatuer coding.

    So far only binaries smaller than 64KB can be run and only in user mode not kernel mode. NO ACCESS TO KERNEL NO DIRECT ACCESS TO FIRMWARE Still a long way to go before a full exploit.

    http://www.gbax.com/drmgp2x.html details the DRM in the GP2X. And plus, I'd imagine it somewhat tricky to implement on a Linux-based platform.

    Looks like one of Wraggsters cronies has come to visit. Adblock his website and you'll be fine. Or better yet, don't visit any of the dcemu.co.uk ripoff site and visit a real page. Google will have some fine alternatives.

    Have you guys not heard of the Firmware changer? There will be no need to upgrade from 1.50 to 2.00 when GTA: LCS arrives. Just run this program and it will let you play it on a 1.5 PSP
