131w ago - Following up on the previous PS3 Lv0ldr / Bootldr clarifications by marcan42 and wololo, today PlayStation 3 hacker naehrwert has shared some details based on reverse-engineering the exploit used to dump it.

To quote from his blog: The Exploit

As the exploit that was used to dump lv0ldr/bootldr/howeveryouliketocallit is public now, let's have a closer look at it to understand what's going on. Here is what I have reversed from lv0 (it shares the syscon portion of the code with its SPU counterpart):

The syscon library implements some high level functions, e.g. to shutdown the console on panic or to read certain configuration values. Every of this functions internally uses another function to exchange packets with syscon and the exchange function uses the read_cmpl_msg one to get the answer packet. The top-level function will pass a fixed size buffer to the exchange function.

So if we are able to control syscon packets, e.g. by emulating MMIO (and thanks to IBM we are), we can change the packet size between the two packet readings and overwrite the caller stack. And if we first copy a little stub to shared LS and let the return address point to it, we can easily dump the whole 256 kB.

Nothing more left to say now, let's wait and see if this is going to be fixed in future firmware versions (we just have to check lv0 fortunately).

This is a temp thread, if anyone has time to search google or wikis to verify or debunk then we'll either promote or nuke this post accordingly.

We received an e-mail from "anonymous" today stating the following:

Usually such things are posted all over forums and trashed for being BS daily, but who knows maybe someone is actually trying to help the PS3 scene instead of finding new ways to profit from it with unnecessary products to play the newer games.
