The Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.5.4
proceeds with adding to length values without validating the original values,
which allows remote attackers to cause a denial of service (integer overflow
and heap-based buffer overflow) or possibly have unspecified other impact via a
crafted Mac font.
