IOS Briefs

As stated here, JailbreakMe 2.0 simply download and execute a PDF file containing codes created for changes to the mobile operating system (some exploit of PDF font bug)...so yes, we have to fix this hole, in order to prevent malicious softwares to land on your phone by using the same technique !

thanks to macstories.net, all you have to do is to :

- com.willstrafach.pdfexploitwarner_1.0.0-4_iphoneos-arm.deb
- Place it in /var/mobiledevice using iFile on the iPhone.

- Using Terminal :

--> ssh root@your IP address
--> alpine
--> dpkg -i file.deb

Where “alpine” is the default password you’ll get after installing Open SSH from Cydia and “your IP address” is located under Settings – > Wifi – > active wifi connection.

- Using iFile :

--> Navigate to /var/mobile and double tap on the .deb file to install it.

Please be aware that this won't fix the issue, but it'll simply ask you if you really want to open a .PDF every single time.
