Description
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.
