I've got to head out of town on short notice and may not make it back to
this thread for a few days, but this is just too good to wait. Notice
especially the part about how the vulnerability was found.  :)

http://www.securitytracker.com/alerts/2004/Feb/1009067.html

SecurityTracker Alert ID:  1009067
CVE Reference:  GENERIC-MAP-NOMATCH   (Links to External Site)

Date:  Feb 15 2004

Impact:  Execution of arbitrary code via network, User access via network

Exploit Included:  Yes  
Version(s): 5 (6 is reportedly not vulnerable)

Description:  A vulnerability was reported in Microsoft Internet
Explorer (IE) version 5. A remote user can execute arbitrary code on the
target system.

It is reported that a remote user can create a specially crafted bitmap
file that, when loaded by IE, will trigger an integer overflow and
execute arbitrary code.

The author states that this flaw was found by reviewing the recently
leaked Microsoft Windows source code. The flaw reportedly resides in
'win2k/private/inet/mshtml/src/site/download/imgbmp.cxx'.

The report indicates that IE 5 is affected but that IE 6 is not
affected.

A demonstration exploit is provided in the Source Message [it is Base64
encoded].  

Impact:  A remote user can cause arbitrary code to be executed on the
target user's computer when the target user's browser loads a specially
crafted bitmap file. The code will run with the privileges of the target
user.  Solution:  No solution was available at the time of this entry.
