pdffix Saurik released a PDF patch for older and already jailbroken iOS devices

As you may know, few days ago Apple had released a new version of iOS for all its mobile devices except first-generation iPhone and iPod touch, so owners of the latter are still not protected from a security flaw that allows hackers to obtain a remote control of their handsets. In fact, the latest compatible version for them is currently iOS 3.1.3.

But Saurik (who is known as a developer of Cydia) recently announced on the Dev-Team blog that he released a PDF patch that is compatible with any iOS version down to 2.x. It can be found in Cydia if you’ll search for “PDF Patch”. After installing it you can check if the patch is working properly with visiting jailbreakme.com page. After sliding the box to jailbreak you should only see the star background (and not a dialog box), which means you are no longer vulnerable.

In its blog Dev-Team also noted:

“Since the only reason for 4.0.2 was to fix the security holes, and since the upcoming Cydia package will fix them too (and then some!), everybody should sit tight on 4.0.1 (or lower) and install the Cydia package as soon as it’s out. Jailbreakers can have their cake and eat it too.”

Today Apple released patches for its iOS that address a security hole in Mobile Safari, which allowed users to jailbreak their iDevices. The PDF exploit they used also allowed hackers to gain remote control over the device with an iOS.

iOS 4.0.2 is available for:

Apple did NOT release the patch for the first generation iPhones.

iOS 3.2.2 is intended to use on the iPad and iPad 3G.

You can update your device via the links above or simply by connecting your device to iTunes and clicking Update. But note, if you want to continue using jailbreak you should not update your handset/tablet and don’t forget to backup your SHSH blobs.

pdf exploit Howto secure iPhone iOS: PDF exploit fix

There is a big a security hole in iPhone iOS. The device is insecure in a big and obvious way. You should be extremely careful of what sites you visit.

The FlateDecode vulnerability can be used when a PDF File is embedded within a Web page. Basically Safari tries to parse the PDF. And when it does it executes some code. Hackers can use this exploit to read and write iPhone data, get your contacts, sms, even delete something. So they can get all kinds to access your personal information stored on your iOS device.

Apple will fix it some day. Until then you need to take care of your iPhone security. There is a fix for that. It is available via Cydia for jailbroken devices. So you need to jailbreak in order to secure (funny isn’t it?).
