Microsoft DirectShow buffer overflow

Overview

A buffer overflow in Microsoft DirectShow may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Microsoft DirectShow is a programming architecture for streaming multimedia on the Microsoft Windows platform. An input validation error in the DirectShow architecture may allow a buffer overflow to occur in applications or components that use DirectShow. If a remote, unauthenticated attacker supplies an application or component that uses DirectShow with a specially crafted media file, that attacker may be able to trigger the buffer overflow and, consequently, execute arbitrary code.

For more information, including a list of affected software, please see MS05-050.

Impact

By convincing a user to open a specially crafted media file with an application that uses DirectShow, an attacker may be able to execute arbitrary code with the privileges of the user.

---

Solution

Apply an update

Microsoft has addressed this issue in Microsoft Security Bulletin MS05-050.

---

Do not accept media files from untrusted sources

By only accessing media files, such as *.avi files, from trusted or known sources, the chances of exploitation are reduced.
