Without trying to test anything, it just may be exploitable via a 
"shortcut" file or a Packager "package", either embedded or in the form 
of a standalone (.SHS or similar) file.  If so, that potentially opens 
up a few "assisted remote" (i.e. the user has to double-click an 
attachment, click a URL link, etc) exploit options...
