Overview

Apple has reported a vulnerability in the way Mac OS X 10.4 systems handle TIFF images that could cause affected applications to crash or allow remote code execution..

Description

TIFF Image File Format

The TIFF image file format is a widely supported file format used for storing images.

Integration
