Homebrew Possible Exploit?

[BurningDesire]

Sometimes when I watch a long Youtube video (10-30min) the Youtube app crashes and forces me to restart my system. I have the New 3DS with 9.5.0. Could we use this to make a new homebrew? Also, does this happen to anyone else. I was thinking a stack buffer overflow would be useful but I don't know.

Keep in mind, that the 3DS has got ARM NoeXecute(NX) enabled.

 

[BurningDesire]

What exactly is that?

 

[AtlanticBit]

a thing that the ARM processor has. only the kernel can set up places where code can be executed.

 

[BurningDesire]

So even if we found the bug we couldn't execute code from unless we magically got kernel access?

On a side note: you can play youtube videos with the N3DS' internetbrowser. You don't need the app.
But the problem with NINJHAX is not that the entrypoint was fixed but a later vulun. You can read http://smealum.net/?p=517 to find out more.

I still don't understand why people think a crash immediately equals an exploit/buffer overflow/hax. 95% of the time this isn't the case especially with the security measures the 3DS has in place. Wouldn't you think Nintendo learned its lesson from the DS/Wii fiasco?

I found that if you open the 3ds while powered on and rake a paperclip across the board randomly the sysnand itself totally crashes. Hax?

Yeah thats probably true.

That somehow sounds like how they found out we could rewrite the DS firmware!

so far it's only allowed me to run roms from the sd card.

Comically enough this sounds like a very simplified version of how Team Tweezers hacked the Wii. :-)

Not exploitable. As others have pointed out the 3ds's NX bit will stop this from being exploitable- we might get ROP, but actual code will require a lot more than just a YouTube video crash.

Besides, isn't the GW online launcher painful enough? And you want to make me watch a half hour video first as well?!? :-D

Notice I said DS and not 3DS!

But what if everyone who found any crash or bug in the system reported it? Could it be possible to figure out at least something from sheer amount of exploits?
And obviously we wouldn't go around creating whole threads dedicated to a exploit, just make a sticky or something.

Its posts like this that made me leave gbatemp for months at a crack. Crashes have almost zero chance of being exploitable.

I know that, I was just considering the small chance of a crash being exploitable. Then so many crashes could lead to one or two exploits.
It's kind of like button mashing in smash, just hope you land a hit or two.

You guys keep associating crashes with exploits and it really doesn't work that way. If you are able to run custom code through a fault in some software, then yes, that software will crash when that code is run. but crash does not equal exploit. Your chances of finding an exploit through a software crash are zero. These arnt the days of the original xboxs. Processors prevent custom code from simple over runs. Do you get it now? These threads are pointless and very annoying.
