Apple Mac OS X vulnerable to buffer overflow in ColorSync ICC color profile handling

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

Overview

Apple's Mac OS X operating system contains a flaw in the handling of ICC color profiles, which may allow arbitrary code execution through a heap-based buffer overflow.

Description

The Apple Mac OS X operating system contains support for ICC color profiles in the ColorSync component. This component contains a flaw in checking boundary conditions which may allow arbitrary code execution. When checking certain parameters in ICC color profiles, improperly formatted or maliciously crafted embedded profiles may cause a heap-based buffer overflow which would allow arbitrary code execution.

Impact

An attacker with the ability to supply a maliciously crafted profile may be able to execute arbitrary code on a vulnerable system.  The attacker-supplied code would be executed with the privileges of the user running ColorSync.

Solution
