APPLE-SA-2013-10-22-1 iOS 7.0.3
iOS 7.0.3 is now available and addresses the following:
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
CVE-2013-5162 : Tomer and Mor
Phone
Available for: iPhone 4 and later
Impact: A person with physical access to the device may be able to
call arbitrary contacts
Description: Race conditions existed in the Phone app at the lock
screen. Under various circumstances, the Phone app may allow access
to the Contacts pane. This issue was addressed by preventing this
display of the Contacts pane while the phone is locked.
CVE-ID
CVE-2013-5164 : Dany Lisiansky
