Bug description:
  Ubuntu 14.04's libfreetype has not been patched with the fix for [1], thus applications that use libfreetype6 are vulnerable to infinite loops. e.g. Chromium / Google Chrome. [2] If you add a small patch to apply freetype commit 
  df14e6 [3], that should fix the problem. I verified this locally.

  I have not checked other Ubuntu releases to see if they are affected.
