Available for: iPhone v1.0 through v1.1.1, iPod touch v1.1 and v1.1.1
Impact: Viewing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution.

This update addresses the issues by performing additional validation of TIFF images. These issues do not affect Mac OS X v10.3.9 systems with Security Update 2006-004, Mac OS X v10.4.7 systems with Security Update 2006-004, or systems running Mac OS X v10.4.8 or later.
