Hi,

After working around the PDF format specification for some time,
finding some interesting stuff around the way it declares objects and
handles embedded binary streams, this issue came up quickly:

I'm curious regarding previous research around PDF and PostScript (if
possible, not involving Javascript :o) ). The nice fellows of the
Information Assurance group at NSA in charge of SELinux development,
and Red Hat, seemed to have interest on printing labeling, etc.

PS/PDF turn out to be really complex and error-prone... I wouldn't be
surprised if someone can dig up a decent amount of issues in parsers
and related applications.

I've been poking around some tools for the framework I was working on
(thankfully using Metasploit's Rex library, although the module
loading engine is much more simple as there's no need for the whole
module inheritance/mixins/dependencies stuff). Probably will release
some code after the month ends, hoping someone will do something else
far more useful with it than breaking OS X :>

Cheers.
