iPhone / iPod touch v1.1.3

• Foundation

  CVE-ID: CVE-2008-0035

  Available for: iPhone v1.0 through v1.1.2, iPod touch v1.1 through 1.1.2

  Impact: Accessing a maliciously crafted URL may lead to an application termination or arbitrary code execution

  Description: A memory corruption issue exists in Safari's handling of URLs. By enticing a user to access a maliciously crafted URL, an attacker may cause an unexpected application termination or arbitrary code execution. This update addresses the issue by performing additional validation of URLs.

• Passcode Lock

  CVE-ID: CVE-2008-0034

  Available for: iPhone v1.0 through v1.1.2

  Impact: An unauthorized user may bypass the Passcode Lock and launch iPhone applications

  Description: The Passcode Lock feature is designed to prevent applications from being launched unless the correct passcode is entered. An implementation issue in the handling of emergency calls allows users with physical access to an iPhone to launch an application without the passcode. This update addresses the issue through an improved check on the state of the Passcode Lock.
