Apple iPhone/iPod touch Prior to iOS 4 Passcode Lock Authentication Bypass Vulnerability
Apple iOS for iPhone and iPod touch is prone to an authentication-bypass vulnerability.
An attacker with physical access to a locked device can exploit this issue to bypass the passcode and access the user's data. This may aid in further attacks.
Versions prior to iOS 4 are vulnerable.
NOTE: This issue was previously covered in BID 41016 (Apple iPhone/iPod touch Prior to iOS 4 Multiple Vulnerabilities) but has been given its own record to better document it.
