Vulnerability Note VU#546772

Apple Mac OS X JPEG2000 image handling buffer overflow

Original Release date: 02 Oct 2006 | Last revised: 21 Nov 2006


Apple Mac OS X fails to properly handle JPEG2000 files. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial-of-service condition.


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 JPEG2000 images.


By convincing a user to view a specially crafted JPEG2000 image, 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 that uses ImageIO may be vulnerable.
