Vulnerability Note VU#650681

Apple Mac OS X ImageIO fails to properly handle corrupt GIF files

Original Release date: 27 Sep 2005 | Last revised: 27 Sep 2005


The Apple Mac OS X ImageIO framework contains a buffer overflow that may allow a remote attacker to execute arbitrary code.


Apple ImageIO is an image processing framework that was introduced in OS X 10.4 (Tiger). ImageIO is used by several applications, including WebCore and Safari. ImageIO contains an unspecified buffer overflow in the handling of GIF images.


By convincing a user to view a specially crafted GIF image (e.g., contained within a web page), an attacker could execute arbitrary code with the privileges of the user. The attacker could also cause the application using the ImageIO library to crash. Any application which uses ImageIO may be vulnerable.
