FreeType is vulnerable to out-of-bounds write issues. These writes are caused by a heap-based buffer overflow in the t1_builder_close_contour function in psaux/psobjs.c. If a malformed font is supplied, it is possible that the contour variable is started but no points added, causing the buffer overflow.
