Apple releases iOS 4.3.4 update

By | July 15, 2011, 11:26am PDT

Apple has released a security update for iOS that fixes the exploit used for easy jailbreaking of devices.

This update fixes the PDF vulnerability used on the JailbreakMe.com site to easily jailbreak the device via the Safari mobile browser. This update means that hackers won’t be able to use the same vulnerability to compromise iOS devices.

Apple took nine days to plug this hole.

If you want to be protected, fire up iTunes, connect your iOS device and download this update. If you want to jailbreak your device using JailbreakMe.com, then do so and then install the third-party patch created by the jailbreak community to plug the hole (or wait for an alternative jailbreak mechanism to come out). In my opinion, not installing this patch (or at the very least the third-party patch) is foolhardy given the scope of the vulnerability.

iOS update 4.3.4 is for GSM iPhone 4, iPhone 3GS, iPad 2, iPad, and third- and fourth-generation iPod touch. If you have a Verizon CDMA iPhone 4 then you need iOS 4.2.9.

Apple took nine days to plug this hole

Yeah I'd call them out on this too - 3 months to plug a hole that allows people to steal you personal data, but only 9 days to plug a hole that lets the owner jailbreak his property.

I agree, this is no coincidence

Also note that Apple takes far longer to fix serious security errors in OS X, again because there is no such thing as jailbreaking in OS X. You get the feeling that Apple doesn't place as high a priority on the safety of their consumers than they do on the safety of their revenue streams.

Good day to confirm this comment I would appreciate T h e b e s t o f Z D N e t d e l i v e r e d your website very nice to everyone Yes, Oracle is the only one with shared-disk architecture, but that is there advantage. It means you can add or remove nodes and the database lives on. In a shared nothing architecture, if you lose a node, you lose the system. I'm sure Oracle appreciates EMC highlighting their advantage.I also desire to signal in your RSS feeds. Thank you as soon as once again and maintain up the great operate Awesome post! Thank you very much || thanks for nice content this is really benefit to me.
