JailbreakMe 3.0 – one of the easiest solutions to jailbreak iPhone, iPad and iPod Touch that was released by Comex earlier today uses a userland exploit to jailbreak and install Cydia on an iOS device.
Experts have raised concerns that the vulnerability in iOS could be exploited in a similar way by malicious websites to install malware.
It is also expected that Apple will release iOS 4.3.4 software update to patch the exploit very soon. If you don’t want to upgrade to iOS 4.3.4, but don’t want to be exposed to the security vulnerability then you will be relieved to know that there is a solution for you.
Comex has also released a patch called PDF Patcher 2 on Cydia to fix the vulnerability associated with viewing malicious PDF files. It can be installed on any firmware version.
You can follow these instructions to install the PDF Patcher 2 on your jailbroken iOS device:
- Launch Cydia from your jailbroken iOS device homescreen.
- Tap on the Search tab and search for PDF Patcher 2.
- Tap on PDF Patcher 2 from the search results and then tap on the ‘Install’ button.
- Then Tap on the ‘Confirm’ button to install the patch on your iOS device.
With this you have the best of both worlds, you have patched the vulnerability that is likely to be fixed by Apple in iOS 4.3.4 and you also get to keep your jailbreak.
