Did you know that TTF fonts are turing complete?
http://en.wikipedia.org/wiki/True_Type_Font#Hinting_language
"It really worries me that the FreeType font library is now being made to accept untrusted content from the web.
The library probably wasnâ(TM)t written under the assumption that it would be fed much more than local fonts from trusted vendors who are already installing arbitrary executable on a computer, and itâ(TM)s already had a handful of vulnerabilities found in it shortly after it first saw use in Firefox.
It is a very large library that actually includes a virtual machine that has been rewritten from pascal to single-threaded non-reentrant C to reentrant C⦠The code is extremely hairy and hard to review, especially for the VM."
