iPhone Jailbreak Uses a PDF Display Vulnerability

adeelarshad82 writes "Latest reports indicate that the website that 'jailbreaks' iPhones, iPads, and iPod Touches does so by means of a PDF-based vulnerability in OS X. PDF parsing and rendering is a core feature of OS X, and there have been several other vulnerabilities in the past in iOS CoreGraphics PDF components." As Gruber points out, the proper term for this is not "jailbreak," but "remote code exploit in the wild."

  1. not really that great a piece of work is it? by Serendip7 · · Score: 1, Offtopic
    This exploit was already fixed in OSX with a patch..

    Comex basically just diff'd what was fixed in the latest OSX patches against what was in the last iOS patch. Then read up on this patch that hasn't made it to iOS yet. FYI, this won't work if you have 4.1 beta or higher installed supposedly (cuz Apple already had the patch bundled up ready to go when they release the next build)...

    The real credit goes to Charlie Miller who found this problem in the first place.

    The funny thing I found was that Charlie Miller was given credit by Apple in the patch note.. "Credit to Charlie Miller working with TippingPoint's Zero Day Initiative for reporting this issue." but then Charlie tweets about p[articular exploit.. "Very beautiful work,"... "Scary how it totally defeats Apple's security architecture."
