      Description

      ros 0.4.9-RC-35-g3eb03ef

      I can make ros assert in WIN32K freetype remotely via webbrowser. This is 100% reporducible for me.

      Reproduction steps
      -Install ros
      -Install Opera 12.18 from rapps
      -browse to www.palemoon.org

      *** Assertion failed: style_name
      ***   Source File: ../../win32ss/gdi/ntgdi/freetype.c, line 4031

      It will assert in freetype over and over, I took the bts in react.log
      when I finally *t*erminate the thread, ros will BSOD.

      I consider this critical, because most likely we do not have much time (before the website changes) and this has dramatic security implications ofc.
