In September 2004, Microsoft released a security update for the GDI+ component. Does this affect PSP Thumbnail Handler?
If you have PSP Thumbnail Handler 1.x installed and you are running Windows 2000, your computer is using a vulnerable version of GDI+. You should install PSP Thumbnail Handler 2.1, which contains the updated version of GDI+. If you are running Windows XP or Windows Server 2003, then PSP Thumbnail Handler uses the GDI+ component that is maintained by the operating system. Verify that your system is up to date by visiting Windows Update.
