  OVERVIEW

This is a Trend Micro generic detection for JPEG image files that exploit the MS04-028 vulnerability, which is also known as Buffer Overrun in JPEG Processing (GDI+), to allow code execution in the affected system.

These JPEG image files may be crafted maliciously to contain executable code such that the code is automatically executed when the image files are viewed on vulnerable or unpatched systems. The code may also execute even when the image files are simply previewed as thumbnails. The crafted files may also cause Windows Explorer to crash.

  TECHNICAL DETAILS

NOTES:

This is a Trend Micro generic detection for JPEG image files that exploit the MS04-028 vulnerability, which is also known as Buffer Overrun in JPEG Processing (GDI+), to allow remote code execution of Load Modules/Plugin on the affected system.

These JPEG image files may be crafted maliciously to contain executable code such that the code is automatically executed when the image files are viewed on vulnerable or unpatched systems. The code may also execute even when the image files are simply previewed as thumbnails. The crafted files may also cause Windows Explorer to crash.

Some normal JPEG image files have also been found to crash Windows Explorer inadvertently due to the presence of the JPEG GDI vulnerability. Trend Micro antivirus also generically detects these files, which contain extended "comment" sections that cause the exploit, as EXPL_MS04-028.A.
