iOS 7.0.3

• Passcode Lock

  Available for: iPhone 4 and later

  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 while a notification was being swiped and while the camera pane was partly 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.

  CVE-ID

  CVE-2013-5144 : Dany Lisiansky

• Passcode Lock

  Available for: iPhone 4 and later

  Impact: The time delay for incorrect passcode attempts may be bypassed

  Description: When returning to the passcode lock from the Phone app, the passcode entry view is sometimes visible when it should not be, and so may be accessed even if the iPhone has been disabled due to many incorrect passcode attempts. This issue was addressed by updating the visibility of the passcode entry view on state changes.

  CVE-ID

  Available for: iPhone 4 and later

  Impact: A person with physical access to the device may be able to call arbitrary contacts
