Vulnerability Note VU#945747

Mac OS X executes 'recent items' with privileges of foreground application

Original Release date: 05 Nov 2001 | Last revised: 05 Nov 2001

Overview

The "recent items" feature of MacOS X allows users at the console to trivially obtain root privileges.

Description

MacOS X includes a feature called recent items. Recent Items is a list of documents and applications that have recently been accessed. An application launched from the Recent Items list runs with the privileges of the foreground application, not the privilege of the console user. This enables a trivial exploit to gain root access from the console.

Impact

Attackers with access to the console (i.e. logged in at the desktop, not remotely) can gain root access.

Solution

Use the Software Update feature of MacOS X to install the security update dated 10-19-2001.
