https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=981
* include/freetype/fterrdef.h (FT_Err_DEF_In_Glyf_Bytecode): New
error code.
* src/truetype/ttinterp.c (Ins_FDEF, Ins_IDEF): Prohibit execution
of these two opcodes in `glyf' bytecode.
(TT_RunIns): Don't enforce reexecution of `fpgm' and `prep' bytecode
in case of error since function tables can no longer be modified
(due to the changes in `Ins_FDEF' and `Ins_IDEF'). This change can
enormously speed up handling of broken fonts.
* src/truetype/ttdriver.c (tt_size_request): Revert change from
2011-07-16; the intended metrics fix seems now to be implemented in
a different way, making the patch unnecessary. Note that this
change was usually patched out by all major GNU/Linux distributions
due to heavy side effects.
* src/truetype/ttgload.c (compute_glyph_metrics, TT_Load_Glyph):
Refer to the metrics of the `TT_Size' object.
At least on FreeBSD there is a global declaration of `index' in file
`/usr/include/strings.h'.
* src/cff/cf2intrp.c, src/truetype/ttgload.c: s/index/idx/ where
appropriate.
* src/sfnt/ttkern.c (tt_face_load_kern): Don't check for
cross-stream kerning tables since we reject format 2 tables later
on anyways.
Modify code for limit test...
(tt_face_get_kerning): ... to avoid a limit test here.
Reported by Alexander Hedges <ahedges@student.ethz.ch>.
* src/pcf/pcfdrivr.c (pcf_property_set, pcf_property_get): Tag
`property_name' with `FT_UNUSED' where necessary.

https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=935
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<callothersubr>: Since there is not a single flex operator but a
series of subroutine calls, malformed fonts can call arbitrary other
operators after the start of a flex, possibly adding points. For
this reason we have to check the available number of points before
inserting a point.
* src/base/ftmm.c (FT_Set_Var_Design_Coordinates,
FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Ignore
return value of `ft_face_get_mvar_service'; instead, check whether a
service is actually returned.
Too much local variables holding different structures were called
`metrics'.
* src/truetype/ttdriver.c (tt_size_select): s/metrics/size_metrics/.
* src/truetype/ttgload.c (tt_get_metrics_incr_overrids,
compute_glyph_metrics): s/metrics/incr_metrics/.
(load_sbit_image): s/metrics/sbit_metrics/.
* src/truetype/ttobjs.c (tt_size_run_fpgm): s/metrics/size_metrics/.
(tt_size_init_bytecode): s/metrics/tt_metrics/.
(tt_size_reset): s/metrics/size_metrics/.
We have to make a separate case for Windows 64's LLP64 data model.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h (FT_UINT_TO_POINTER): New macro.
* src/truetype/ttgload.c (load_truetype_glyph): Use it.
