Buffer Overflow Found in PSP Firmware v2.0 90

Posted by Zonk 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."

      There is no point in a PSP Virus, If any of them were mass-bricked, It would end up hurting nobody but sony in the long run because they would have no choice but to fix all the bricked psp's...

      I'm sure somebody could write somthing to brick a psp using the lua language...even just ruin somthing by possibly clocking up all 3 processors by insane amounts then make it do millions of simple commands over and over till it breaks... But the only way it would really spread would be way of the homebrew, and its not like wifi would spread it because nomatter what to recive somthing via wifi you must:

      1: Have the wlan switch on
      2: Have an active connection
      3: Accept this file

      Therefore any worm that would be released would proove useless...

      And if anybody is dumb enough to shop on their psp, well then they should have their identity stolen for not having anywhere near enough security!

        Cabir replicates over bluetooth connections and arrives to phone messaging inbox as caribe.sis file what contains the worm. When user clicks the caribe.sis and chooses to install the Caribe.sis file the worm activates and starts looking for new devices to infect over bluetooth.

      • Now, I'm all for hacking your PSP into whatever you want it to be, but it's not like Sony's pulling a bait-and-switch. They wanted this thing to be a tightly controlled console that only ran their approved code, and it's been that way since day one. If you bought it with other intents in mind, then hey, have fun making it meet them, but it's not like you can claim that Sony misled you.

    Why throw your money at Sony, who does their best via DRM and everything to keep you out, when open platforms like the Tapwave Zodiac [portagame.com] invite developers in?

    Of course, this "feed the hand that bites us" behavior among gamers has already forced the Zodiac off the market -- nobody was buying it.

    Ditto XBox! Why do geeks, who should oppose every shred of DRM and proprietarism that the green thing embodies, go out and buy the thing only to turn it into a set-top linux box? Hello? You're throwing money AT the evil empire.

    I understand there's a certain challenge to "owning" such a closed system. Fine, show Microsoft and Sony you're better than them. But at the end of the day, all this activity does is encourage MORE of exactly the wrong behavior on the megacorps' part.
    • Because the Zodiac kinda blew? Being an "open" system does not make something a "quality" system.
      • Actually the Zodiac itself had a better hardware spec than the DS in the shape of vastly more memory, superior support via it's ATI Imageon graphics card, higher resolution display and a much faster CPU). It also had a much sleeker form factor and had the added bonus of being a functional PDA with a huge library of Palm software available for it (something I wish the PSP had).

        Obviously this came at a cost - it was double the price (so at the PSP price point, but with less than PSP level performance, and wit

      they still require signing but are more likely (relative to sony) to grant you "authorization" (don't you just like how in the modern world you need permission to access your own property?)

      so the tapwave isn't a good example.

      a good example would be something like the gamepark32 (and it's newer brother). there's no "signing" required or supported on the hardware.

      And that means we don't uphold our principals 100% of the time. Sure, I'm against closed standards. What's that? A dirt-cheap linux box, with a small (for a PC) form-factor, and they're all identical? I'll take three!
      What? Microsoft? Bah, you know they actually LOSE money on the X-Box hardware, don't you?

      • sadly, if a console is open, you can bet that the openness will be used 95% of the time to play pirated games, not homebrew ones.

        There is a middle ground of legal emulation. If you own a copy of a Lucasarts adventure game, and you use your right under 17 USC 117 to use ScummVM DS [drunkencoders.com] to install it onto a CompactFlash card and then put the CF card into an adapter [ndshb.com] on your Nintendo DS, you can still play commercial quality games without piracy.

        Quite simply because commercial games are of much higher quality

        • That's all fine and dandy except that falls within the 5% (and I think that's highly generous) of homebrew users. Most people will just download isos from some 0-day warez site and play them on their system, completely ignoring all the homebrew software out there. And the few people enjoying homebrew don't make up for the much larger number of people warezing commercial games.

      Frankly, I own a gaming console, you know, for gaming. You may notice a highlighted word there. Hint, it's: gaming.

      I do not buy it to make some political statement about open vs closed software. I buy it to play games on it. If Sony has the games I want to play, and some hypothetical vendor has this super-open GPL-conform Stallman-approved ESR-blessed platform without many games, you can guess whose I'll buy. Hint: it starts with "So" and ends with "ny".

      The whole "feeding the hand that bites us" metaphor is emotional and all, but I don't feel bitten at all so far. I gave them some money, I got some games I wanted in return. If anything, I'm "feeding them" to get more games like those in the future. But more pragmatically, I'm not "feeding" anyone. I'm just acting in my own interest as a consumer, and buying the one that's the better product for me right now.

      And if DRM is what it takes to get those games, fine by me. I can still plug the cartridge or UMD in and play the game, right? Well then why should I care what technologies went into that UMD or the loader in the BIOS?

      You assume too much that all geeks are like this or that, all are on a zealot crusade against the very idea of commercial software, and all bought an XBox or a PSP just to run Linux on it. Which is just false. I for example am a terminal geek all right, but I bought my XBox to actually run XBox games like Fable or Jade Empire. Even those two alone make it well worth every cent MS got from me. I know only two people who've modded their XBox and that was to add some multimedia functionality and IIRC a bigger hard drive, not to run Linux on it.

      Basically rest assured that when you read news about someone's uber-l33t port of Linux to some game console, you're really reading about a small minority that gives a damn at all, and mostly just to show that they can do it. It's the geek equivalent of showing that you can tear a phonebook with your bare hands: it's not actually _needed_ (there are easier ways to destroy a phonebook), it's not what everyone buys a phonebook for, and it doesn't make it a better phonebook than it was before being torn. It's just a way to show off. Unlike tearing a phone book with your bare hands, though, pretty much noone else gives a damn about it.

      Now lot more people will care about it if it lets them pirate UMD games and play them off the memory card. (That was the main reason people modded their PS1, PS2 and XBox, btw: to be able to play pirated games.) But even then we're talking freeloaders, not people on a holy jihad for the glory of OSS. Rest assured that _all_ they wanted was to let someone else (e.g., the rest of us paying customers whose money keeps those devs in business) pay the tab for their gaming, not to make some "free as in speech" political point.
    • Er.

      It might have something to do with Sony's hardware still being supported, as opposed to Zodiac discontinuing [palminfocenter.com] support.

        Code in user mode can't demand that the kernel do anything. It can ask and see what happens. The kernel will decide itself what it wants to do. There's no direct access to the firmware, thread/process manager etc. from user mode.

I don't plan on owning a PSP so it doesn't really affect me, but I still hope that maybe in the future they will release cheaper development kits that use disks that have less capacity so they can't be used to pirate games but they can still be used to make some small games.
