iOS Vulnerability: Please Update
Apple has released a software patch for a serious SSL bug in iOS 6 and 7. This update is available for all compatible iOS devices, please backup your phone and update immediately.
The version of iOS on a device can be checked by launching the Settings app, selecting General, and then selecting About. To update, launch the Settings app, select General, select Software Update, and update to iOS 7.0.6 (or 6.1.6 on the iPhone 3GS and 4th Gen iPod Touch).
The vulnerability is an apparently errant line in Apple’s “Secure Transport” API that causes signature verification to never fail. This allows unchecked attackers to impersonate “trusted” servers and intercept and decrypt communications at will.
The same SSL bug also exists in OS X 10.9 Mavericks, and Apple has promised that a patch is “coming soon”; the patch is expected to be released sometime later this week. OS X 10.8 Mountain Lion and earlier versions of OS X do not seem to have the vulnerability. If you use OS X 10.9 Mavericks, please use an alternative browser such as Firefox or Chrome for the meantime.
