Microsoft Windows Task Scheduler Buffer Overflow

Original Release date: 13 Jul 2004 | Last revised: 13 Jul 2004

Overview

Microsoft Windows Task Scheduler has a buffer overflow that may allow a remote or local intruder to execute arbitrary code.

Description

Microsoft Windows Task Scheduler (Mstask.dll) is a COM-based API (ActiveX control) that provides a scheduling service for executing arbitrary commands on a system. It contains a buffer overflow that is reported to be caused by failing to properly check some attribute of the names of the commands the scheduler is tasked to execute. Exploitation of this overflow could allow an intruder to execute arbitrary code if the intruder can convince the victim to visit a malicious web page or, in some circumstances, open a malicious email message, or a file with the extension .JOB. For more information, see Microsoft Security Bulletin MS04-022.

Microsoft Windows Server 2003 is reportedly not affected by this issue.

Impact

An intruder could execute arbitrary code with the privileges of the user logged into a vulnerable system.

Solution

Apply a patch as described in Microsoft Security Bulletin MS04-022.
