Name of the Vulnerable Software and Affected Versions FreeType 2 versions prior to 2017-03-08

Description The issue is caused by a heap-based buffer overflow related to the TT Get MM Var function in truetype/ttgxvar.c and the sfnt init face function in sfnt/sfobjs.c, resulting in an out-of-bounds write.
