Install PDF Patcher 2 To Fix JailbreakMe 3.0 Vulnerability

JailbreakMe 3.0

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.

    so with this i can get my CDMA iphone4 iOS 4.3.3 jailbroken?

  • El Hache

    If I’m already jailbroken with redsnow 4.3.3, iphone 4, do I need to use this patch?

    • Jeroenxp

      Yes. The vulnerability stays on al devices even with redsnow en snowbreeze. Because the PDF read function in iOS is vulnerable.

  • JC

    Re-booted….everything is fine now…..thx

  • alain

    I tried my friend’s iphone with IOS 4.2.1 on firmware 3.10.01. When i try d/l cydia, it stops halfway and the icon disappeared. I did a reboot on his iphone and i’m now stuck at the reboot screen with the Apple logo on it, and it kept rebooting by itself without going into main screen. Plug it in into iTunes is useless too. Please help!!

    • Kimk69

      The jailbreak is only for iOS 4.3.3.
      You’ll have to restore mostlikely.

    • Boss

      I had similar problem..All you have to do is – just restore with custom ios version if u wan to unlock….

  • Stan

    I can’t find it in Cydia.

  • Ton

    Now here’s a situation:
    I have updated both my ipad 2 and iphone 4 to 4.3.3 but i cannot use jailbreakme pdf exploit unless restore devices. I did restore the ipad cause there’s no other way, but i dont wanna restore the iphone. I will probably use redsnow to have the jailbreak done. Is there any proof that the vulnerabilty exists in pre-set IOS devices?

  • dres

    I’ve done everything and all seemed well until I clicked on my apps and all they do is crash, what’s causing this and how can I fix? Thanks

    • http://Dcskate7@yahoo.com Chris

      Hey this happened to me. All my AppStore apps would open an crash. I did some research and fixed the problem. U prob already fixed it or restored by now but all u have to do is hook ur phone to computer, run iTunes, then under view or file(one of the top choices in iTunes I forget sorry) it will say deauthorize device. Do that. Than authorize ur device right after that. Than sync, and bam ur apps will work. Idk why but it works. GL

    Can someone please help me?

    I have an iPhone 3GS and I used the previous jailbreakme to get to 4.0, I am on 05.13.04 baseband. This is all I have done to the iPhone, no unlocks, just the jailbreak.

    I understand that I have to get it to 4.3.3 to use jailbreakme 3.0, but how should I go about doing this?

    Should I just plug it into iTunes and update to latest? I don’t know if I should be concerned about iTunes updating the baseband or something.

    Thanks for your reply! I’m sure more people are in the same boat with me

    • Boss

      As per my knowledge…if u do it with itunes…it is going to update yoru baseband to latest..If you ever want to unlock..u can do it and just jailbreak with jailbreakme3…if u want to unlock , then better use sn0wbreeze to jailbreak and unlock.

      I dont think, jailbreakme preserves baseband..Thanks

    I installed PDF Patcher 2. Now I can’t seem to play QuickTime audio and videos on safari. I haven’t done anything else to the phone. I was running 4.3.2 and used ih8sn0w to update and jailbreak to 4.3.3 after all this happened. I’ve cleared cache, cookies, history, reset network and I’m still not able to view video or audio on safari. I also used to be able to view the desktop version of yahoo.com. Now I can only view the mobile version. I’m at a loss. Any help would be greatly appreciated. For all I know it may not be PDF Patcher that caused this.

    Just tried to JB and unlock my Iphone 4 WITHOUT success. JB seems to work BUT unlock does not. In fact, for some reason I cannot use my Iphone with the SIM that was working BEFORE I JB and/or tried to unlock it. Now it does not work with ANY SIM!! So confused now.

    I JB using redsn0w rc15 with 4.3.3 (baseband 04.10.01). Then ran redsn0w rc16 for the bug fix and also tried ultrasn0w 1.2.3 as well.

    All other functions seem to work and I can use it as an Itouch with WiFi but phone functionality seems to not work at all. Disappointed to say the least and would appreciate any help.

    If it is not appropriate to ask here, could someone point in the right direction on where to go to ask? Probably need to speak to Comex or Dev team and hopefully they will read this.

  • da beast

    yes of course it is vunerable, if you can download malicious software to the iphone, which the comex did created a version of jailbreak to be done so on the ios 4.3.3. Then it shows that this 4.3.3 ios firmware is not that safe. So yes even if you jail broken it with Redsnow, do install pdf patcher.
