Subject: Backdooring PDF Files

Recently, there has been alot of hype involving backdooring various
web technologies. pdp (arcitect) has done alot of work centered around
this area.

I saw Jeremiah Grossman mention PDF's being "BAD", however, I was
unable to easily locate any practical reasons as to why. I decided to
investigate this a little further.

This article discusses two possible backdoor techniques for Adobe
Acrabat Reader and Professional. It includes proof of concept code and
backdoored PDF documents.
