A PDF file is just a program written in the Postscript programming language
-- a program describing how to draw the page/screen. Bugs in implementations
of Postscript, or of the libraries which Postscript calls, can be where the
vulnerability exists.

That is, it's not about PDF containing an executable. A PDF file IS an
executable.
