Security issues?

I tought 1.50 was still locked tight : )

Guess someone hit a sensitive point...

Now it's time for another appeal to Sony? If you can't beat them, join them...

so it isn't available for download yet?

Post by **Drakonite** » Tue May 10, 2005 9:01 pm

Er... that looks to say "1.50" to me, and the firmware is identical to the 1.50 firmware.

Either the page changed or you were mistaken.

i try to update my sys, and i get your sys is up to date. i got firm 1.5 so is not available yet

pedroleite · Post by **pedroleite** » Tue May 10, 2005 9:09 pm

I didn't said it was available... nor the page from sony JP implied it...

Another EBOOT.PBP to toy with... what joy... :)

Maybe they will just allow to run unsigned ELF again... a security problem reversed... (if you run unsigned there's less chance of trying to break the encryption...)

pdc · Post by **pdc** » Tue May 10, 2005 9:10 pm

It definately looks like there is an update coming.

http://www.playstation.jp/psp/update/ud_01.html

At the top of the page, there is a news announcement from today (2005.05.10) and reference to "1.51".

Perhaps someone who reads Japanese will be able to explain better.

If I was Sony I would keep fixing every security hole discovered by homebrewers and hope they find no way to reflash older firmwares, or find a way to prevent it.

This gives two benefits:
1. Prevents mass-abuse of the PSP platform for illegal content usage. Granted its not there yet, but I have no doubt ppl elsewhere are looking for ways. Hopefully that never happens.

2. If anyone truly wants to simply homebrew, they need to track down the rare PSP that is still fw 1.0. Those people can be ignored because that population cannot increase in size, and will only decrease.

Personally I have no problems with this situation. I think things have happened too fast in the PSP homebrew scene and people need to take a step back for a breath, understand the ramifications of everything thats been done and wrought.

uhm CybBlade, additional security, dont sound like you would want to upgrade.

vimacs. i got my psp with 1.5, now im lost :D

Could be that they overlook something in this next firmware too.

Keep checking http://www.psphacks.net/cgi-bin/ for an update every 15 minutes.

Bear in mind this is from my weak japanese....

It says something to the effect that they know 1.00 had a flaw. Next update will be 1.51. They don't know when they will release it but they will keep us posted. If you don't update via network/PC connection some future games will require the firmware to be updated and ask you to do so(if you want to play).

The part below that where it talks about 1.50 is somthing along the same lines as above...

Curiously the last part (three lines with the third red exclamation mark) seems to mean that if you already have 1.50 you don't need 1.51.

Once again my reading of japanese is much weaker than my speaking.

If the lock is released in the future, PSP will be an excellent homebrew device.

I'll write a midi player that supports dls files for psp. A portable midi player is good.

Woops, my bad. I completely missed the mention of 1.51 in the first blurb on the page.

i wonder if this firmware unlocks the CPU power cuz GT4 Mobile is coming out soon :)

engstrom · Post by **engstrom** » Wed May 11, 2005 1:11 am

CPU unlocking will be on a game by game basis, not in the firmware. If the firmware suddenly doubled the CPU speed your battery would last even less time than it does already and if the devs haven't put frame locks on all parts of their existing games they too would run twice as fast.

No disrespect to anyone but why do so many people think firmware updates are some magical gift channel from Sony? A few weeks ago everyone was getting excited by the Korean launch and the update that was sure to follow that would include a full web-browser. It seemed obvious to me from the outset that the Korean browser was a specific portal to specific content provider by a specific IP.

Anyway the news that Sony is updating the firmware due to 'security issues' doesn't bode well. I'm guessing that 1.5 users will have to wait for a hardware hack to get any homebrew running and any other holes that have been exploited will be sewn up tighter than a...very tight thing.

Ironically making the PSP so secure and adaptable to threats could be the thing that kills it off... I'm not interested about warez in the slightest (I work in the games industry so that would be taking the food from my mouth :-) And no I'm not a tester and I'm not going to try and get a PSP SDK for anyone!) but I would relish the chance to write some homebrew apps/games etc for my PSP. Personally I don't think it will happen for some time (apart from of course the 1.0 users).

It's official right now, i doubt it will support homebrew gaming, i fear it will be quite opposite - but we'll see.

http://psp.ign.com/articles/611/611529p1.html?fromint=1

May 10, 2005 - Sony Computer Entertainment has announced the pending availability of a new firmware update for the Japanese model PSP. The update is mainly a security fix and, following installation, will leave your PSP with system software version 1.51. Further details will be revealed in the near future.

There's no word yet from Sony Computer Entertainment regarding a similar update for the US PSP. If there is a need for a security fix on US systems, we presume SCE will announce the required update shortly.

Open platform does not conflict with security.

An open platform is not that bad as you thought.

Interesting, so this means that 1.50 could have a potential exploit in it, if 1.50 isn't 'tight' enough. Wonder if it has to do with RR, I'll keep messing around with RR anyway. I wasn't expecting another firmware release so soon, then again, neither for the gb emulator :P

Because like most anything else, it is done first in Japan, then the US.

pedroleite · Post by **pedroleite** » Wed May 11, 2005 2:26 am

Actually...

All that I think is required is:

One cert included on the PSP that DOESN'T get's used with something else than homebrew.

All the user made PRX and ELF are encoded with this published cert. All the saves games from this is done with this cert too.

There is no way to reverse the system PRX, boot or game codes.

All publishers are safe, homebrew stops the exploits, and everyone is happy...

What keeps homebrew doing that right now is the lack of the encoding structures, where the cert goes and what comes out...

After this homebrew could "write" to the flash it's own cert, replacing one from sony or adding...

And there goes the crypto...

I think Sony just realized it's a matter of time until someone reverses the ~PSP structure... and after that it's just a way to place the cert in the flash... easy on the 1.0 ?

Flash isn't really easy to write too, blocks get erased and written again.

More likely 1.51 is in response to firmware dumper.

I was thinking more towards UMD dumping.

In this case it is, since its a filesystem... assuming its writable, of course.

So they'de stop the SDK compiled UMD reading examples from running? I think with the games gone by and in development now then that would be a tad difficult. I thought specific UMDs could only be read by their own game boot code because they're keyed, seems the key encryption is hardware side, because I can read any UMD I care to insert. And I can't see how that'll be patched against considering some apps rawread the UMD for access speed. Maybe they found a hole yet to be discovered, wouldn't be the first time.

Now this is weird, isn't it? Why address security issues in (I presume) v1.0 with an upgrade to 1.51 ? Why not make 1.5 users upgrade too? Why not just urge everyone to upgrade to 1.5?
Surely they know that no one with a 1.0 is going to upgrade?
The only people who would upgrade would be people with 1.5 who would think " I may as well.".
One (far-fetched) interpretation of this could be that there is a security wekaness in 1.5 and they want people to upgrade without realising it.

Yes, this is maybe related to the UMD dump, firmware dump is almost impossible to stop. But who know !

Phour20 · Post by **Phour20** » Wed May 11, 2005 7:00 am

Maybe 1.51 is just what they call the last update that Japan got.. Or does the last one exist on their servers too..
