A vulnerability has been identified in Libpng, which could be exploited by attackers to cause a denial of service. This issue is caused by an error in the "png_handle_tRNS()" [pngrutil.c] function when processing a PNG image with a malformed tRNS chunk, which could be exploited by attackers to crash an application linked against a vulnerable library, creating a denial of service condition.

Points: 28.35 Donate | | | 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.

Points: 52.51 Donate | | i was chatting to some knowledgeable guys on IRC, and it seems the best this exploit will do is crash a PSP, not run any unsigned code.....
So in essence, it is useless...
"this could be exploited by attackers to crash an application linked against a vulnerable library, creating a denial of service condition" is the key bit of info  |

Points: 0.01 Donate | | Yea things like this have happened on 2.50 FWs+ in the past and never lead to anythin. So yea won't work and only will crash and over flow the PSP as said already. Kind of the wrong section to put this though.  |
