Yesterday, the new iOS 7.0.3 patch was released . As we mentioned above, the new version does not bring any major changes, but it does come with many bug fixes and necessary security updates.
In addition to addressing the nausea that iOS 7 caused for some users, iOS 7.0.3 comes with three fixes for recently discovered vulnerabilities. These vulnerabilities, if exploited properly by someone with knowledge of the subject, could cause harm or leak personal information.
Apple on its website states that iOS 7.0.3 finally fixes a bug in the lock screen that could cause a reboot and leave camera data exposed.
Description: A NULL dereference existed in the lock screen which would cause it to restart if the emergency call button was tapped while a notification was being swiped and while the camera pane was partially visible. 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.
A second vulnerability it fixes is the Lock Passcode and finally a bug in the phone app that could allow someone with physical access to the device to call your contacts.
However, if you are thinking about a future jailbreak and security is not that important to you, you should not apply the update. The information came right after the iOS announcement by MuscleNerd.
