    The PDF exploit is the exploit used by Comex in Jailbreak Me 2.0. Through this exploit, malicious code can be written to your iDevice through PDF's on websites. PDF Loading Warner only warned you; this new PDF Exploit Patch actually patches the exploit.

    Things needed in this tutorial:
    iDevice Running 3.2/3.2.1 or 4.0/4.0.1 or 4.0GM
    Make sure PDF Loading Warner is NOT installed (BigBoss Repo)



    Cydia:

    1. Open Cydia
    2. Go to Manage -> Sources -> Edit -> Add
    3. Add this source: http://cydia.myrepospace.com/ipodtouch123/
    4. Search for "PDF Exploit Patch" without the quotes and install it Package Removed***

    ***cdevwill tweeted he does not want the package hosted until it is less buggy:

    Open SSH:

    1. SSH into your iDevice
    2. Download this .deb file
    3. Navigate to /var/root/media
    4. Create a folder called Cydia
    5. Navigate to /var/root/media/Cydia
    6. Create a folder called AutoInstall
    7. Navigate to /var/root/media/Cydia/AutoInstall and place the .deb file here.
    8. Reboot your device.
    9. Reboot your device again.

    No, apparently it patches the pdf-loading vulnerability, which is not the actual jailbreak vulnerability. It does not affect your jailbreak.

    @ OP - did you make this? care to explain function/offset you supposedly patched?

    Yes. It patches the PDF Exploit. It makes sure malicious code is not written to your device. Why does it matter that it patches the JailbreakMe exploit? To do this, you'd have already jailbroken and have no need for JailbreakMe. This protects your device from malicious code.

    Exactly what it does.
    As for the function:
    The new exploit used in JailbreakMe is a PDF exploit. This not only allowed JailbreakMe to function, but also makes your device vulnerable to malicious code via PDF files. This file patches the exploit, but does NOT affect your jailbreak in anyway.

    This is under the default BigBoss repo made by cdevwill (aka. chronic). Hopefully you didn't repackage his and put it on your own repo without permission.

    -.-'
    Did you not read it?! PDF Loading Warner is in the BigBoss Repo. That only warns you when a PDF is trying to load. The one in this repo PATCHES the exploit. Gosh. Don't contradict without reading...

    Btw, in the OpenSSH version, you didn't give us a .deb file
