Video of PSP libtiff exploit in Action

Adrian (thanks for the tip!) has sent us word of a video that shows the PSP's libtiff vulnerability in action. For those of you who haven't heard of the libtiff vulnerability before, its a vulnerability which leads to the PSP crashing which could possibly lead to an exploit allowing homebrew to be run. Although Sony were supposed to have 'patched' firmwares 2.01+ for any image browser vulnerabilities, it appears that this one slipped the net. This means that although it hasn't been confirmed, this exploit could be present in firmwares up to 2.80.

The video put together by block10 shows the libtiff vulnerability crashing a 1.50 PSP DevHook-ed up to 2.71. As QJ's Jake said a few days ago: Even if this only works on lower firmwares, it will usher in the age of GTA-less homebrew for 2.01+ PSP's, which will be a welcome change for homebrew enthusiasts. Work on this exploit is continuing, and the guys you need to thank for finding this are NOPx86 (for originally finding this vunerability) psp250, Fanjita and Skylark for working on this. Developers can discuss this in the Developers Dungeon whereas normal forum users can find the appropriate thread in our PSP Hacks Forum.
