Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=1408044. * src/sfnt/ttcolr.c (tt_face_load_colr): When the 'COLR' v1 table header is too small, don't deallocate delta set index map structures.
65f85237	2023-01-17T09:18:25	Update all copyright notices.
6a179ff7	2023-01-16T16:38:56	sr/.c: Various minor fixes. src/autofit/ft-hb.c (_hb_ft_reference_table): Call `FT_UNUSED` after variable declarations. * src/gxvalid/gxvjust.c (gxv_just_widthDeltaClusters_validate): Eliminate unused variable. * src/gzip/ftgzip.c: Don't call GCC '-Wstrict-prototypes' pragma for C++ compiler. * src/sfnt/ttcolr.c (ENSURE_READ_BYTES): Remove final semicolon to avoid compiler warning. * src/sfnt/ttsvg.c (tt_face_load_svg_doc): Fix signedness warning.

(read_paint): Use it – after the start pointer `p` has been checked for whether it allows reading the format byte, each successive paint table field read need to be bounds-checked before reading further values. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=52404
141d979a	2022-10-10T12:25:51	Minor comment changes.

bd417007	2022-09-26T14:46:42	[sfnt] Add SVG document bounds checking. Add a check that the document content is actually contained within the `SVG ` table. Without this check a malformed font may claim arbitrary memory as its document content. * src/sfnt/ttsvg.c (tt_face_load_svg): Take `numEntries` into account when testing 'documentRecord' extents. (find_doc): Rename `stream` to `document_records` for clarity. (tt_face_load_svg_doc): Split `doc` from `doc_list` pointer for clarity. Test that the document content is contained within the table.

33ceac2a	2022-09-15T09:47:07	Reject 'COLR' table if version is 1 but header too small. * src/sfnt/ttcolr.c (tt_face_load_colr): If the version is determined to be 1, then the table size has to be at least the size of the v1 header. Also, for peeking the number of base glyphs and entries in the layer list, ensure that the table is sufficiently long. Fixes #1179. Original patch by Sergey Temnikov.

a1017e26	2022-08-19T19:07:42	[sfnt] Don't require 'gvar' table to support variation fonts. Fixes #1172. * src/sfnt/sfobjs.c (sfnt_load_face): Tag font as Multiple Masters font if `fvar` is present; do not require other tables to be present. * src/truetype/ttgxvar.c (tt_set_mm_blend): Allow for a missing 'gvar' table when setting variation coordinates. However, if a 'gvar' table is actually present, do perform a sanity check and fail on malformedness. (TT_Get_MM_Var): Don't assume 'fvar' needs 'gvar' or 'CFF2 tables in all cases, which is an overly tight check.
4797b2ff	2022-08-26T12:08:34	[sfnt] Avoid undefined shifts in `COLR` v1 color line retrieval * src/sfnt/ttcolr.c (tt_face_get_colorline_stops): Disambiguate shift behavior by using multiplication using macros from ftcalc.h. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=50573

335224be	2022-03-03T16:33:40	[sfnt] Fix bounds check in SVG. The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not protected by parentheses. As a result, the expression `table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to `table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected `table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect bounds check which may lead to reading past the end of the `SVG ` table. * src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in parentheses. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=45179

It is an error to adjust it by one to get the number truncated by a stream error. This is probably inconsequential because valid entries are correctly accounted for. * src/sfnt/ttload.c (check_table_dir): Do not adjust the truncated number of tables.

The gist of this commit is that it doesn't make sense to support WOFF without compression (which would be only possible in WOFF 1.0 anyway). * src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with `FT_CONFIG_OPTION_USE_ZLIB` block. Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block. * src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with `FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code. * src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c, src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks, not parts of the code.

fde91ab8	2021-10-20T11:45:15	[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.
6d12e3a0	2021-10-20T11:38:16	[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.

[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.
