Ben Wagner 535c67dda7 [mm] Tolerate missing Blend dictionary entries
In a Multiple Master font, the Blend dictionary must contain valid
Private, FontInfo, and FontBBox. The current code will error if any of
these are present and invalid, but will not error and will provide
uninitialized data if the Blend dictionary exists but does not contain
one of these entries. This change reverts to the older behavior of
treating any missing entries as containing all zero data and not
returning an error.

In the future it may be best to keep track of when these are actually
initialized and error if they are not.

* src/type1/t1load.c (t1_allocate_blend): Zero initiailize.

Ben Wagner 65be4b2112 [mm] Delay setting blend weight and design position.
Previously the `blend->weight_vector`, `blend->default_weight_vector`,
and `blend->design_pos` were set early to allocated but uninitialized
memory under the assumption that the memory would eventually be
initialized. However, it is possible that some of the required
keywords may not actually be present, leaving the memory uninitialized.
This is different from a present but invalid table, which would produce
an error.

* src/type1/t1load.c (t1_allocate_blend): Remove early allocation and
initialization.
(parse_blend_design_positions, parse_weight_vector): Parse into local
and assign to blend if valid.
(T1_Open_Face): Check that if a blend exists that it has the weight
vector and design positions.

Ben Wagner b5e003f1f2 [cff] Commit vstore data and regions on allocation.
The vstore->regionCount and vstore->dataCount were read directly
from the data. However, vstore->varRegionList and vstore->varData
would still contain uninitialized entries with uninitialized
pointers in the event of an error, leading to issues when attempting
to clean up.

Reportd as
  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104

* src/cff/cffload.c (cff_vstore_load): Read the region and data counts
into locals and update the vstore counts immediately after each entry
becomes free-able.

Ben Wagner fde91ab8f1 [sfnt] Delay setting gasp ranges and count until computed.
Previously, the gasp.numRanges was set and gasp.gaspRanges was
allocated and assigned before a possible early exit if the frame could
not be entered. It is also possible that the gaspRanges allocation
could fail but the numRanges still be set to non-zero. In such cases
an error would be returned, but the face would have a gasp in an
inconsistent state which may still be accessed.

Reported as
  https://bugs.chromium.org/p/chromium/issues/detail?id=1261450

* src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges
and gasp.gaspRanges until after the ranges are initialized.
2021-10-20 11:45:15 -04:00
Ben Wagner 6d12e3a0ca [sfnt] Delay setting names and langTags until computed.
Previously, the table->names and table->langTags fields were created
pointing to uninitialized memory and an early exit could happen if the
frame could not be entered. The caller would then be unable to properly
dispose of the memory as the string fields had not been initialized.

Reported as
  https://bugs.chromium.org/p/chromium/issues/detail?id=1261343

* src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags
and table->names until after the memory they will point to is fully
initialized.

Jan Alexander Steffens (heftig) 842ec5ed62 meson.build (gen_docs): Use `current_source_dir` instead of `source_root`.
These two are not equal when FreeType is used as a subproject, such as in

Hugh McMaster 467e49e817 autogen.sh: Only copy submodules if building from a git branch.
`autogen.sh` fails if building from a standard source tarball.  Firstly, git
expects to be called in a git repository, then `copy_submodule_files`
blindly attempts to copy files.

Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
before compiling to regenerate build files.

This patch ensures that various git commands are only called and 'dlg' files
are only copied if `autogen.sh` is called from a git repository.
