  - Fix security problems
  
  Note:
  An integer overflow error within the "cff_charset_compute_cids()"
  function in cff/cffload.c can be exploited to potentially cause
  a heap-based buffer overflow via a specially crafted font.
  
  Multiple integer overflow errors within validation functions in
  sfnt/ttcmap.c can be exploited to bypass length validations and
  potentially cause buffer overflows via specially crafted fonts.
  
  An integer overflow error within the "ft_smooth_render_generic()"
  function in smooth/ftsmooth.c can be exploited to potentially cause
  a heap-based buffer overflow via a specially crafted font.
