Not sure about the implications for the PSP. Why did you give a topic like this a title like that?
There is no evidence to suggest it's exploitable on the PSP platform. There are so many library 'exploits' that can't be used on the PSP: (libpng, libungif, mpeg libraries, etc). If you have proof of PSP vulnerablity, please tell.

Sorry, but if you're going to post this in the news section, make sure it's news. Kthxbai.
