Vulnerability Note VU#527236

Apple Mac OS X Image RAW vulnerable to buffer overflow via specially crafted Canon RAW image

Overview

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

I. Description

RAW image files provide access to image information directly from a camera's sensor prior to in-camera processing, retaining the maximum amount of image data. This allows for subsequent processing of the information using a raw conversion application such as Aperture and iPhoto.

Apple's ImageIO is an image processing framework that was introduced in Mac OS X 10.4 (Tiger). It includes the ability to process images in a number of different formats, including RAW image files. ImageIO contains an unspecified buffer overflow in the handling of Canon RAW image files.

II. Impact

By convincing a user to view a specially crafted Canon RAW image file, 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.

III. Solution

Update

Apply the update provided by Apple. Refer to Apple Security Update 2004-004 for more information.
