Why do that? In case you really find a buffer overflow and out of a sudden manage to exploit it, you'd only gain the rights on the system every other program has, which is nearly nothing, not even setting mountpoints, so no backups.
With this you could never write inside lv2 kernel space (which the jailbreak can), because every app runs inside a container within RAM, so as soon as you try to do something clever the system will lock up.
So if you have the skills to make exploits, concentrate on porting geohots lv1 exploit to lv2, so we can access the hv that way... more useful then an app in lv2 user space
Yeah... but that would be pretty much it... it would be like HBL for PSP's. So if you are realy interested in this homebrew "scene" of the PS3 which only contains of backup managers which you couldn't use in the end... yeah absolutely.
But even the HBL for the PSP has been able to get kernel access in certain firmwares. If I remember correctly, there was even a ISO loader for one of them (don't feel like looking up which one, but I think it was 5.03). And I'm talking about the models with "un-hackable" MBs (i.e. the 3rd gen PSP-2000s and the 3000s). Also there is the new 6.20 loader that (supposedly) has kernel access and boots to the HBL.
While I would say that the PSP is most likely an easier device to get this kind of access. Any progress with hacking the PS3 is great news. If a HBL can be made to work on PS3s with 3.50 and above, it still means that "the scene" is active and making progress. Good luck to anyone that is helping the PS3 hacking community. Every little bit of working code/exploits helps!
It wasn't a HBL it was a CFW Loader. Pretty the sam like USB Firm Loader will be. The app loaded a cfw live into RAM. There for it was possible to play umd iso´s from mms device.
Wonderkik is right. The ps3 hase a kind of anti buffer overflow system.Its not really anti and even not a system. Its simply the last syscal "lv1_panic" wich will be called in case something is going on that shouldnt be.
Kind of emergency shutdown. And your buffer overflow or virus or trojan are killed
The usb exploit and the payload hack is the only thing we can do to time.
