Apple Mac OS X Finder fails to properly handle malformed .DS_Store files

Vulnerability Note VU#258744

Original Release Date: 2006-11-29 | Last Revised: 2006-11-30

Overview

Apple Finder fails to properly handle malformed .DS_Store files. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code.

Description

.DS_Store files are hidden files used by Apple Finder to control the display of a folder and its contents.

According to Apple Security Advisory 2006-007:

A heap buffer overflow may be triggered when the Finder is used to browse a directory containing a corrupt ".DS_Store" file. By enticing a user to browse a directory containing a maliciously-crafted ".DS_Store" file, an attacker may be able to trigger the overflow. This could lead to an application crash or arbitrary code execution with the privileges of the user running Finder. ".DS_Store" files may be included in archives, on disk images, and on network file systems.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user running Apple Finder.

Solution

Apply Apple Updates

Apple advises all users to apply Apple Security Update 2006-007, as it fixes this and other critical security flaws.
