Macromedia Products Not Affected by Microsoft JPEG/GDIPlus Vulnerability

Macromedia Products Not Affected by Microsoft JPEG/GDIPlus Vulnerability


On September 14, 2004, Microsoft released a security bulletin warning that there may be wide-ranging effects on software that handles JPEG images. Macromedia has reviewed its products and found none of them to be at risk from this issue.


For more technical details, please visit Microsoft’s security bulletin:

For users of Macromedia products, the relevant portion of the bulletin states: “not every program that installs this file is vulnerable to this issue because it may not use the Gdiplus.dll file to process JPEG images. However, only the manufacturer of that program can make that determination.”

Although some Macromedia products do install a vulnerable version of gdiplus.dll, no Macromedia product uses this Microsoft graphics library to process JPEG images, therefore there is no security risk.

In some configurations, the following Macromedia products may install a gdiplus.dll file; however, because these products do not invoke the affected JPEG routines, there is no security risk:

  • Contribute
  • Dreamweaver
  • Fireworks
  • Flash
  • FlashPaper
  • FreeHand
  • RoboSource Control
  • Studio MX


September 21, 2004 – Bulletin first created.
