Buffer Overrun in JPEG Processing Proof Of Concept (MS04-028)
------------------------------------------------------------------------
SUMMARY
In a previously featured article,
<http://www.securiteam.com/windowsntfocus/5VP0H1FE0W.html> Buffer Overrun
in JPEG Processing (GDI+) Allows Code Execution (MS04-028), a buffer
overrun in the GDI+ library was reported. Provided below is a proof of
concept example that will crash various applications attempting to open
the malicious JPEG image.
DETAILS
A proof of concept JPEG image that will crash an application attempting to
open/preview it on an affected platform can be downloaded from

The vulnerability in the comment parsing of the JPEG file is similar to a
previous vulnerability found almost two years ago regarding Netscape
handling of JPEG images. A more thorough analysis of the code and methods
of exploitation can be found at
<http://www.openwall.com/advisories/OW-002-netscape-jpeg/>
http://www.openwall.com/advisories/OW-002-netscape-jpeg/ .
Some antivirus software can detect the presence of such a malicious JPEG
image since the problem is specific in nature and a signature
identification can be made. McAfee's antivirus with virus definitions
version 4.0.4393 or greater can detect the problem.
