iOS 7.0.2 Firmware Update
Yesterday Apple updated its latest version of iOS to version 7.0.2. It is only a minor update, a week and a day after officially releasing iOS 7, the latest (and improved) version of Apple’s mobile Operating System for iPhone, iPad and iPod touch. The iOS 7.0.2 firmware update has the build number 11A501 an fixes a security bug. The bug in question took advantage of a lock screen vulnerability allowing users to bypass the passcode security on a locked device and have access to apps. Apple was of aware of the bug since last week when the company publicly announced that there will be a fix in a future software update. The iOS 7.0.2 firmware update does not only fix the lock screen security bug, but also another iOS 7 bug that allows users to make a call while the iPhone is in passcode protected lock screen mode.
This is how Apple describes the bugs that the 7.0.2 fixes:
“Impact: A person with physical access to the device may be able to make calls to any number
Description: A NULL dereference existed in the lock screen which would cause it to restart if the emergency call button was tapped repeatedly. While the lock screen was restarting, the call dialer could not get the lock screen state and assumed the device was unlocked, and so allowed non-emergency numbers to be dialed. This issue was addressed by avoiding the NULL dereference“.
“Impact: A person with physical access to the device may be able to see recently used apps, see, edit, and share photos
Description: The list of apps you opened could be accessed during some transitions while the device was locked, and the Camera app could be opened while the device was locked“.
Besides the above mentioned bug fixes, the iOS 7.0.2 software update also brings back the option to have a Greek keyboard for passcode entry, an option that was omitted in the previous iOS 7 build. In order to install the iOS 7.0.2 update OTA (over the air), on your iOS iPhone, iPad or iPod touch you will have to go to Settings, then to General and from there to Software Update. The software update’s size will depend on your iOS device’s model and your iOS version.
The previous iOS 7 update was iOS 7.0.1 and it was released together with the iPhone 5S on September 20th, two days after iOS 7’s official release. The 7.0.1 software update fixed an iOS 7 bug that involved denying Touch ID fingerprint authentication for quite a few purchases through iTunes Store. There are also rumors claiming APple is hard at work on an iOS 7.1 software update. Unlike the 7.0.2 update, the iOS 7.1 update is expected to be a major update, adding new functionality and support for new hardware such as the upcoming iPad 5 that is rumored to be released next month.
