Thanks to corelanc0d3r for: "DEPS" - Precise heap spray for FF/IE8/IE9/IE10

Well, the bug isn't in the app itself, but in a third party dll "PDF In-The-Box" from http://www.synactis.com
Logic Print 2013 uses an old version of the dll, new ones aren't affected,
the ROP is from an os dll: [msi.dll] (C:\WINDOWS\system32\msi.dll) 3.1.4001.5512
