Apple ColorSync contains a buffer overflow vulnerability that may allow an attacker to execute arbitrary code.
ColorSync is Apple's color management API. OS X applications and devices can use ColorSync profiles to determine how colors in images should be interpreted.
ColorSync contains a stack based buffer overflow. An attacker may be able to trigger the overflow by convincing a user to open an image with specially crafted embedded ColorSync profile.
From Apple's Color Management with Mac OS X Panther document:
Based on the Portable Document Format (PDF) 1.4 standard, Quartz is the native Mac OS X 2D drawing engine that generates text, vector, and raster images onscreen. Applications that use Quartz automatically support ColorSync. These applications include Preview, Mail, and Safari—all of which come with Panther.
Any application, including Safari, Mail and Preview, that can open images and process their ColorSync profiles may be affected by this vulnerability.
A remote, unauthenticated attacker may be able to execute arbitrary code by convincing a user to open a webpage, email message, or image file.
Apple has issued an upgrade to address this issue. See Apple Security Update 2007-003 for more details.
