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.
