Apple updates for iOS and iWork '09 fix 4 security flaws

Filed Under: Apple, iOS, Vulnerability

iPhoneHot on the heels of last week's release of OS X 10.7 (Lion), Apple has released three security updates for its office suite, iWork, and one security fix for iOS on iPhone, iPod Touch and iPad.

iOS has been updated to version 4.3.5, unless you are a Verizon user in which case you get iOS 4.2.10. This update fixes a flaw in X.509 certificate handling and could allow attackers to intercept SSL/TLS secure connections from iDevices.

I recommend applying this update as soon as possible as this could be a serious security and privacy risk. As usual you can get the update inside of iTunes and need to connect your Apple device to iTunes to apply the update.

This is a very common technique for exploiting people this year as Kris Braun and I discussed in this week's Chet Chat.

iWork updates can be applied through the Software Update application found under the Apple logo in the upper-left corner of OS X user's desktops.

    You forgot to tell the millions of jailbreakers not to update if they don't want to lose their jailbreak.

    I jailbroke my one iPhone and my other 3 are unjailbroken and I am downloading the updates for them now

    That's a shocking error in the SSL handling. That's one of the most basic things to get wrong in checking certificates. Microsoft had a similar flaw in IE many years ago which was well known, so Apple really should have known better.

    What exactly do I download for my ipad2 and how do I get to it.

    I for one am not going to risk my jailbreak. Think about it. Where do you get wifi outside your own home that doesn't immediately demand a credit card? And as for cellular data, I never activate that anyway due to roaming charges.
