CVE-2008-4230
The Passcode Lock feature in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 displays SMS messages when the emergency-call screen is visible, which allows physically proximate attackers to obtain sensitive information by reading these messages. NOTE: this might be a duplicate of CVE-2008-4593.
