If an attacker created a specially-crafted image file and tricked a local, unsuspecting user into loading the image file in an application that uses the TIFF image manipulating library, it could cause that application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

Even is right: this fix is busted and will reject files that should be accepted, including some produced by libtiff itself. See analysis and corrected patch at the upstream bug linked in comment #23.
