Technical Cyber Security Alert TA04-260A

Microsoft Windows JPEG component buffer overflow

Original release date: September 16, 2004

Last revised: --

Source: US-CERT

Systems Affected

This vulnerability affects the following Microsoft Windows operating

systems by default:

* Microsoft Windows XP and Microsoft Windows XP Service Pack 1

* Microsoft Windows XP 64-Bit Edition Service Pack 1

* Microsoft Windows XP 64-Bit Edition Version 2003

* Microsoft Windows Server 2003

* Microsoft Windows Server 2003 64-Bit Edition

Other Microsoft Windows operating systems, including systems running

Microsoft Windows XP Service Pack 2, are not affected by default.

However, this vulnerability may affect all versions of the Microsoft

Windows operating systems if an application or update installs a

vulnerable version of the gdiplus.dll file onto the system.

Please note that this vulnerability affects any software that uses the

Microsoft Windows operating system or Microsoft's GDI+ library to

render JPEG graphics. Please see Systems Affected section of the

vulnerability note to determine if third-party software is affected. A

list of affected Microsoft products is available in Appendix B, or for

the complete list of affected and non-affected Microsoft products,

please see Microsoft Security Bulletin MS04-028.

Overview

Microsoft's Graphic Device Interface Plus (GDI+) contains a

vulnerability in the processing of JPEG images. This vulnerability may

allow attackers to remotely execute arbitrary code on the affected

system. Exploitation may occur as the result of viewing a malicious

web site, reading an HTML-rendered email message, or opening a crafted

JPEG image in any vulnerable application. The privileges gained by a

remote attacker depend on the software component being attacked.

I. Description

Microsoft Security Bulletin MS04-028 describes a remotely exploitable

buffer overflow vulnerability in Microsoft's Graphic Device Interface

Plus (GDI+) JPEG processing component. Attackers can exploit this

vulnerability by convincing a victim user to visit a malicious web

site, read an HTML-rendered email message, or otherwise view a crafted

JPEG image with a vulnerable application. No user intervention is

required beyond viewing an attacker-supplied JPEG image.

Any applications (Microsoft or third-party) that use the GDI+ library

to render JPEG images may present additional attack vectors for this

vulnerability. While some applications use the Windows operating

system version of the GDI+ library, other applications may install and

use another version, which may also be vulnerable. Microsoft has

created a GDI+ Detection Tool to help detect products that may contain

a vulnerable version of the JPEG parsing component. Microsoft

Knowledge Base Article 873374 provides instructions on how to download

and use this tool.

In addition to running Microsoft's detection utility, we recommend

searching your system for "gdiplus.dll" to help determine what

third-party applications may be affected by this vulnerability. Also

note that applications may re-install a vulnerable version of the GDI+

library if re-installed after a patch has been applied.

We are tracking this vulnerability in Vulnerability Note VU#297462.

This reference number corresponds to CVE candidate CAN-2004-0200.

II. Impact

Remote attackers exploiting the vulnerability described above may

execute arbitrary code with the privileges of the user running the

software components being attacked.

III. Solution

Apply patches from Microsoft

Apply the appropriate patches as specified in Microsoft Security

Bulletin MS04-028. Please note that this bulletin provides several

updates to the operating system and various applications that rely on

GDI+ to render JPEG images. Depending on your system's configuration,

you may need to install multiple patches.

In addition to releasing some patches on Windows Update, Microsoft has

released some patches on Office Update, and developer tool patches are

available from MS04-028.

Apply patches from third-party vendors

Third-party software that relies on GDI+ to render JPEG images may

also need to be updated. Apply the appropriate patches specified by

your vendor. Please see the your vendor's site and the Systems

Affected section of the vulnerability note for more information.

Depending on your system's configuration, you may need install

multiple patches.

Follow Microsoft recommendations for workarounds

Microsoft provides several workarounds for this vulnerability. Note

that these workarounds do not remove the vulnerability from the

system, and they will limit functionality. Please consult the

"Workarounds for JPEG Vulnerability - CAN-2004-0200" section of

Microsoft Security Bulletin MS04-028.
