         This module will generate three files: an INF, a GIF, and a PPSX file. You are required to

         In detail, the vulnerability has to do with how the Object Packager 2 component
         (packager.dll) handles an INF file that contains malicious registry changes, which may be
         leveraged for code execution. First of all, Packager does not load the INF file directly.
