97251fd5 | 2023-08-21 23:23:22 | [base] Improve the matrix degeneracy check. Also fixes #1251. * src/base/ftcalc.c (FT_Matrix_Check): To avoid overflow, scale by shifting. * include/freetype/internal/ftcalc.h (FT_Matrix_Check): Update description. | |
 |
a9793fea | 2023-08-15 11:30:26 | [base] Avoid UB with memcpy `FT_NEW_ARRAY(p, 0)` sets `p` to `NULL`. `FT_Stream_ReadAt` with a memory based stream uses `FT_MEM_COPY` which is `memcpy` which specifies that it is undefined behavior for either the `src` or `dst` to be `NULL`. Instead of forcing all callers work around calling `FT_Stream_Read` when `buffer == NULL && count == 0` do the check in `FT_StreamRead`. This allows any call with `count == 0` to succesfully read zero bytes without UB. * src/base/ftstream.c (FT_Stream_ReadAt): skip `FT_MEM_COPY` when `count == 0`. (FT_Stream_TryRead): ditto Fixes: #1250 | |
 |
a20de84e | 2023-08-12 11:47:41 | Fix warnings in tracing messages for 32bit compilation. Since we now require C99, use `%td` for `ptrdiff_t` and `%zu` for `size_t`. | |
|
3829fdaa | 2023-08-04 11:41:23 | Avoid overflow in COLR bounds checks. The values read into `base_glyphs_offset_v1` and `layer_offset_v1` may be in the range 0xFFFFFFFD-0xFFFFFFFF. On systems where `unsigned long` is 32 bits adding 4 to such values will wrap and pass bounds checks but accessing values at such offsets will be out of bounds. On the other hand `table_size` has already been tested to be at least `COLRV1_HEADER_SIZE` (34) so it is safe to subtract 4 from it. * src/sfnt/ttcolr.c (tt_face_load_colr): subtract 4 from `table_size` instead of adding 4 to font data offsets in bounds checks Fixes: https://crbug.com/1469348 | |
|
95a87208 | 2023-08-01 22:48:31 | * src/base/ftobjs.c (open_face_from_buffer): Silence `maybe-uninitialized`. We never call this function without a `driver_name` (#1245). | |
|
b2584c73 | 2023-07-28 22:35:58 | [truetype] Reduce v40 footprint. * src/truetype/ttgload.c (TT_HInt_Glyph, tt_loader_set_pp, tt_loader_init): Refactor code. | |
|
1ecfd219 | 2023-07-27 16:12:28 | [truetype] Remove Infinality for good (remaining bits). * src/truetype/ttobjs.h: Remove remaining fields. * src/truetype/ttinterp.c: Do not initialize them. * include/freetype/internal/tttypes.h: Remove descriptions. | |
|
5b7e45ac | 2023-07-27 15:06:38 | [truetype] Remove Infinality for good. Remove everything `#ifdef TT_SUPPORT_SUBPIXEL_HINTING_INFINALITY`, which was undefined for a while now. * include/freetype/internal/tttypes.h: Ditto. * src/truetype/truetype.c: Ditto. * src/truetype/ttdriver.c: Ditto. * src/truetype/ttgload.c: Ditto. * src/truetype/ttinterp.c: Ditto. * src/truetype/ttinterp.h: Ditto. * src/truetype/ttobjs.c: Ditto. * src/truetype/ttsubpix.[ch]: Remove files. * src/truetype/rules.mk: Don't mention "ttsubpix.c". | |
 |
7c542d02 | 2023-07-21 21:31:28 | * src/smooth/ftgrays.c (FT_SSE2): Fix definition for VMS. | |
|
dd3c9c5f | 2023-07-18 13:25:57 | [woff2] Clean up on large brotli expansion * src/sfnt/sfwoff2.c (woff2_open_font): set error and goto cleanup Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60711 | |
|
336503df | 2023-07-16 07:36:01 | [woff2] Avoid allocation bomb. This is a fix for commit 85167dbd5, reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60615 * src/sfnt/sfwoff2.c (MAX_SFNT_SIZE): New macro. (woff2_open_font): Use it to limit the maximum size of an uncompressed WOFF2 font. | |
|
3c92e7bf | 2023-07-14 18:58:55 | [cff] Fix compiler warning. * src/cff/cffparse.c, src/cff/cffparse.h: Make `cff_parse_fixed` a local function. | |
|
85167dbd | 2023-07-13 16:49:34 | [woff2] Remove sfnt size guess check In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value is now just a hint and a conforming implementation must not reject otherwise valid data if the `totalSfntSize` turns out not to be exact. * src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed woff2 data would fit in the sfnt size guess. Fixes: #1235 | |
 |
26a7f047 | 2023-07-11 01:40:25 | [cff] Make blend operator work with floats in private dicts. The CFF2 blend operator takes N default values and corresponding sets of deltas and pushes N values specific to a designspace location. CFF has a floating point numeric type and the FreeType blending code was not converting those into its internal 16.16 Fixed type format. Fixes #1243. * src/cff/cffparse.c (do_fixed): Handle floating point numbers. Also fix scaling overflow check for integer-to-fixed conversion. * src/cff/cffload.c (cff_blend_doBlend): Updated. | |
 |
dec2743e | 2023-07-07 19:24:48 | * src/truetype/ttgload.c (TT_Hint_Glyph): More mostly cosmetic update. This is a follow-up to commit 49c74ac02, which creates a new local variable "exec = loader->exec", and shortening a lot of "loader->exec". This commit does two more such changes missed in that first commit. Signed-off-by: Hin-Tak Leung <htl10@users.sourceforge.net> | |
 |
355e9197 | 2023-07-06 21:07:16 | [gzip] Don't compile internal zlib development files when using system zlib. `src/gzip/rules.mk` compiles the internal zlib sources even when using the zlib development files provided by a host system. If the internal zlib development files are not present, FreeType fails to build from source. This patch ensures the internal zlib development files are only prerequisites when not using zlib development files on a host system. * src/gzip/rules.mk (GZIP_DRV_SRCS): Define conditionally. | |
|
e4586d96 | 2023-06-24 05:18:54 | * Version 2.13.1 released. ========================== Tag sources with `VER-2-13-1'. * docs/VERSION.TXT: Add entry for version 2.13.1. * docs/CHANGES: Updated. * docs/release, docs/README, builds/macs/README: Updated. * README, src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.13.0/2.13/1/, s/2130/2131/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 26:0:20. * CMakeLists.txt (VERSION_PATCH): Set to 1. * subprojects/libpng.wrap, subprojects/zlib.wrap, subprojects/dlg: Updated. | |

5c00a468 | 2023-05-17 01:29:40 | Comment fixes. | |
|
86d0ca24 | 2023-06-09 05:13:47 | [sdf] Correct handling of empty glyphs. This is a refinement of commit 7b3ebb9. * src/sdf/ftsdfrend.c (ft_sdf_render): Goto 'Exit' instead of directly returning. (fd_bsdf_render): Ditto, also taking care of setting `FT_GLYPH_OWN_BITMAP` correctly. | |
|
7bed7a02 | 2023-06-01 21:05:32 | Fix some `FT_Fixed` vs. `FT_Long` confusion. `FT_Fixed` and `FT_Long` are both typedef'ed to be `signed long`. However, `FT_Fixed` implies that the lower 16 bits are being used to express fractional values and so these two types should not be confused. * include/freetype/internal/services/svmm.h (FT_Set_MM_Blend_Func): Use `FT_Fixed` for `coords`. Users are passing `FT_Fixed` and implementations are taking `FT_Fixed`. (FT_Get_MM_Blend_Func): Ditto. * src/autofit/afcjk.c (af_cjk_metrics_check_digits): Use `FT_Long` for `advance` and `old_advance`. `advance`'s address is passed as `FT_Long*` to `af_shaper_get_elem`, which writes the advance in em units (not fixed). The exact value is not important here as it is only compared to check whether it has changed. * src/autofit/aflatin.c (af_latin_metrics_check_digits): Ditto. | |
|
2fb8eda5 | 2023-06-01 19:38:36 | */*: Remove many function pointer casts. In C it is undefined behavior to call a function through a function pointer of a different type. This is now detected by the Control Flow Integrity Sanitizer. All known issues have already been fixed. Prevent any accidental re-introduction by removing function pointer casts when defining services. The services will call the service functions through the function pointers on the service. As a result the functions must have the same type so there should be no need to cast. Removing the casts allows compilers to warn about assignment to an incompatible function pointer type. | |
|
b641b607 | 2023-06-03 06:09:30 | Minor formatting. | |
|
80a507a6 | 2023-05-23 13:13:56 | Replace `sprintf` with `snprintf`. Fixes #1233. * include/freetype/config/ftstdlib.h (ft_sprintf): Replace with... (ft_snprintf): This new macro. * src/autofit/afhints.c (af_print_idx): Add argument to pass the buffer size. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Updated. * src/bdf/bdflib.c (BUFSIZE): New macro. (bdf_parse_properties_, bdf_parse_start_): Use `ft_snprintf`. * src/tools/ftrandom/ftrandom.c (do_test): Use `snprintf`. | |
 |
115e9275 | 2023-05-19 12:11:45 | [truetype] Reduce heap allocation of `deltaSet` variation data. `deltaSet` is an array of packed integers that can be 32 bits, 16 bits, or 8 bits. Before this change, these values were unpacked to 32-bit integers. However, this can cause big heap allocations, e.g., around 500 KByte for 'NotoSansCJK'. To reduce this amount, store the packed integers and unpack them just before passing to the calculation. At calculation time, due to the variable length of region indices, temporary heap allocations are necessary. This heap allocation is not negligible and visible in `ftbench` results. So, use stack-allocated arrays for short array calculations. Fixes #1230. * include/freetype/internal/ftmmtypes.h (GX_ItemVarDataRec): New fields `wordDeltaCount` and `longWords`. * src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Load packed data. (tt_var_get_item_delta): Unpack data before applying. | |
|
416d4c25 | 2023-05-15 15:44:36 | Add new load flag `FT_LOAD_NO_SVG`. Modern color fonts often contain both an 'SVG' and 'COLR' table. FreeType always preferred 'SVG' over 'COLR' (this was a design decision), however, this might not be the right choice for the user. The new flags makes FreeType ignore the 'SVG' table while loading a glyph. Fixes #1229. * include/freetype/freetype.h (FT_LOAD_NO_SVG): New macro. * src/base/ftobjs.c (FT_Load_Glyph), src/cff/cffgload.c (cff_slot_load), src/truetype/ttgload.c (TT_Load_Glyph): Use it. | |
|
e1a4e081 | 2023-05-12 22:27:08 | [cache] Merge functions. * src/cache/ftccache.c (FTC_Cache_Init): Merge into... (ftc_cache_done): ... this function, with unnecessary checks removed. | |
|
771ff8bd | 2023-05-12 22:21:47 | [cache] Minor casting and cosmetic updates. * src/cache/ftcglyph.c (ftc_gcache_{init,done}): Remove casting. (FTC_GCache_Lookup): Cosmetic variable renaming. * src/cache/ftcsbits.c (ftc_snode_compare): Formatting. | |
|
ad708d70 | 2023-05-11 17:41:49 | [cache] Revise the dynamic hash table accounting. Instead of counting entries relative to the middle of the hash table, this switches to the absolute counter with the full index range mask. As a result, some calculations become a bit simpler. The cache resizing logic stays largely the same. * src/cache/ftccache.h (FTC_NODE_TOP_FOR_HASH): Revised with new counter. * src/cache/ftccache.c (ftc_get_top_node_for_hash): Ditto. (ftc_cache_resize): Simplify reallocations and stop their zeroing. (ftc_cache_init): Stop over-allocating but keep zeroing initially. (FTC_Cache_Clear, FTC_Cache_RemoveFaceID): Updated accordingly. | |
|
6ca0a935 | 2023-05-11 14:31:23 | [t1cid] Set FT_FACE_FLAG_CID_KEYED. * cidobjs.c (cid_face_init): Set FT_FACE_FLAG_CID_KEYED. * cidriver.c (cid_get_is_cid): Comment about the case that is_cid cannot guarantee the glyph collection specification. | |
|
c3876354 | 2023-05-09 07:15:53 | * src/smooth/ftgrays.c (FT_SSE2): Don't define for VMS. | |
|
e02a40a4 | 2023-05-08 20:12:26 | * src/cff/cffdrivr.c (cff_glyph_load): Fix guard for `size`. This was forgotten to change in commit 2b54eba36b (in May 2004). Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=58739 | |
|
5edd6d52 | 2023-05-08 07:22:59 | Minor compiler warning fixes. * src/autofit/afcjk.c (af_cjk_get_standard_widths), src/autofit/aflatin.c (af_latin_get_standard_widths): Use `FT_CALLBACK_DEF`. * src/cff/cffparse.c (cff_parser_run): Initialize and fix allocation of `q`. | |

It is equivalent to `ftc_gnode_compare` and becomes completely meaningless with fixed signatures. Update all callers. * src/cache/ftcsbits.c, src/cache/ftcsbits.h (FTC_SNode_Compare): Remove redundant function.

c8a24209 | 2023-04-27 11:40:46 | [truetype] Fix PostScript name handling for variation fonts. A variation font's PostScript name of a named instance is usually different from the PostScript name of an unnamed instance. However, if a change between a named instance and an unnamed instance with exactly the same design axis values happened, it was possible that the PostScript name wasn't correctly updated. This commit reorganizes the code to handle this issue within the top-level API functions, using a new service to trigger recomputation of the PostScript name. * include/freetype/internal/services/svmm.h (FT_Construct_PS_Name_Func): New typedef. (FT_Service_MultiMasters): New field `construct_ps_name`. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/base/ftmm.c (FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Call `mm->construct_ps_name` to handle `postscript_name`.

6713b1e4 | 2023-04-26 12:03:04 | [truetype] Fix deactivation of variation font handling. According to the documentation, the functions `FT_Set_Named_Instance`, `FT_Set_MM_Design_Coordinates`, `FT_Set_Var_Design_Coordinates`, and `FT_Set_Var_Blend_Coordinates` can unset the `FT_FACE_FLAG_VARIATION` flag. (The same is true for `FT_Set_MM_WeightVector` but this information was accidentally omitted from the documentation.) However, if a call of these functions didn't change the axis values this could fail because internal shortcuts exited too early. This commit reorganizes the code to handle `FT_FACE_FLAG_VARIATION` in the top-level API functions, also taking care of the issue at hand. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_MM_WeightVector, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Handle `FT_FACE_FLAG_VARIATION`. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design, TT_Set_Named_Instance) Don't handle `FT_FACE_FLAG_VARIATION`. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_WeightVector, T1_Set_MM_Design): Ditto. * src/cff/cffobjs.c (cff_face_init): Use `FT_Set_Named_Instance` instead of low-level functions. * src/truetype/ttobjs.c (tt_face_init): Ditto. | |

be15811c | 2023-05-03 01:31:37 | [t1cid] Improve cid_get_cid_from_glyph_index(). Update cid_get_cid_from_glyph_index() to return an error and CID=0 in the case that the specified glyph index points to an invalid entry. cidgload.h (cid_compute_fd_and_offsets): Declare new helper function to set the fd_select and 2 offsets to access the glyph description data. cidgload.c (cid_compute_fd_and_offsets): Move the part loading fd_select and 2 offsets from cid_load_glyph() to here. If the loaded parameters are broken, return the Invalid_Offset error. This function does not load the glyph data, only fills these parameters. (cid_load_glyph): Use new helper function in above. cidriver.c (cid_get_cid_from_glyph_index): Check whether the requested glyph index points to a valid entry, by calling cid_compute_fd_and_offsets(). If it is valid, fill the cid by the glyph index (=CID). If it is invalid, return an error and fill the cid by 0. | |

966ff5a5 | 2023-04-28 15:25:20 | * src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash. The situation can happen if `FT_New_Face` (or one of its siblings) is called with a negative index to get the number of contained faces, followed immediately by a call to `FT_Get_Postscript_Name`. While this is not a valid use of the FreeType library there is no need for a crash. Fixes #1219. | |

f312b340 | 2023-04-22 02:11:21 | [t1cid] Change the trace messages of the charstrings retrieval errors. The t1cid driver catches 3 types of errors in the charstrings retrieval; A) The invalid FD number, there are 2 subtypes; A-1) FD number is the maximum number fitting to FDBytes. A-2) FD number is greater than num_dicts. B) Declared length is overrunning. C) Declared length is invalid (its end is before its head). Considering that some widely distributed fonts (e.g., "CJKV" book by O'Reilly) have A-1 errors in the unimplemented glyphs, the trace level for A-1 is calmed to level 1. The errors A-2, B, and C would be irregular; their trace levels are kept at level 0, but the updated trace messages include the CID number. | |

c4fe77c3 | 2023-04-17 11:17:16 | [truetype] tt_size_reset_height to take FT_Size The `MetricsVariations` `FT_Size_Reset_Func` is defined to take an `FT_Size`. Because `tt_size_reset_height` is to be used as such a function, it must also take an `FT_Size` instead of a `TT_Size`. Even though the pointers passed will be the same at runtime, calling a function through a pointer of a different type from the original function pointer type is undefined behavior. This may be caught at runtime by Control Flow Integrity with something like clang's `cfi-icall`. Issue: https://crbug.com/1433651 * src/truetype/ttobjs.h (tt_size_reset_height): take `FT_Size` * src/truetype/ttobjs.c (tt_size_reset_height): take `FT_Size` and update documentation | |

e78e2d29 | 2023-04-06 11:16:29 | [sfnt, truetype] Add `size_reset` to `MetricsVariations`. This is a generalization of commit ``` commit e6699596af5c5d6f0ae0ea06e19df87dce088df8 Author: Werner Lemberg <wl@gnu.org> Date: Thu Feb 2 11:38:04 2017 +0100 [truetype] Fix MVAR post-action handling. ``` It is also possible for plain `CFF ` style fonts to contain an `fvar` and `MVAR` table and use `cff_metrics_adjust`. `tt_size_reset` should only be called with `TT_Size` and never with `CFF_Size`. Allow the "metrics-variations" service to specify the correct function (if any) to reset `FT_Size`s after adjusting metrics. * src/truetype/ttobjs.c (tt_size_reset): Split off some functionality into... (tt_size_reset_height): ... this new function. * src/truetype/ttdriver.c (tt_service_metrics_variations): Add `size_reset`. (tt_size_select, tt_size_request): Updated. * src/truetype/ttobjs.h: Updated. * include/freetype/internal/services/svmetric.h (MetricsVariations): Add `size_reset`. (FT_DEFINE_SERVICE_METRICSVARIATIONSREC): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec_): Rename `var` to `tt_var` and add `face_var`. * src/cff/cffdrivr.c (cff_service_metrics_variations): Add `size_reset`. (cff_hadvance_adjust, cff_metrics_adjust): Updated. * src/cff/cffobjs.c (cff_face_init): Use `face_var`. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `face_var`. * src/sfnt/ttmtx.c (tt_face_get_metrics): Use `tt_var`. * src/truetype/ttgxvar.c (tt_size_reset_iterator): Renamed to... (ft_size_reset_iterator): ... this new function. Call `size_reset`. (tt_apply_mvar): Pass `size_reset` to `ft_size_reset_iterator`. Fixes #1211 | |

1a4c18f7 | 2023-04-10 15:30:43 | Align `char_next` return types.

d2544433 | 2023-04-08 23:15:41 | [sfnt] Clean up CMAP{4,12,13} handling. This moves the charcode overflow checks upstream and turns some while-loops into the do-while ones to avoid the uninitialized warnings. This should slightly reduce the number of checks and jumps. * src/sfnt/ttcmap.c (tt_cmap{4,12,13}_next, tt_cmap{4.12.13}_char_map_linear): Remove the charcode overflow check. (tt_cmap{4,12,13}_char_map_binary): Ditto and use do-while. (tt_cmap{12,13}_char_next): Add the overflow check. | |

|
9597a62b | 2023-04-01 22:34:30 | [sfnt] Consolidate POST version 2.0 and 2.5 (pt 1). The deprecated POST version 2.5 can be handled using the data structures of version 2.0. The goal is to reduce the footprint. * include/freetype/internal/tttypes.h (TT_Post_Names): Absorb and... (TT_Post_20, TT_Post_25): ... remove these structures. src/sfnt/ttpost.c (load_post_names, tt_face_get_ps_name, tt_face_free_ps_names, load_format_20): Updated accordingly. (load_format_25): ditto and convert offsets to glyph indices. | |

|
4f0a55d1 | 2023-03-19 10:13:52 | [cff] Rework the stream limit checks. The old stream limit checks, before 6986ddac1ece, were good but pointless for the crafted t2_strings. Checking limits there is not necessary as they are created to hold all data. By using two conditions, we can detect the actual crossing of the stream boundary as appropriate for the stream pointer only. The t2_strings parsing will not be triggering these checks. * src/cff/cffparse.c (cff_parser_within_limits): Removed. (cff_parse_real, cff_parse_integer): Redesign the stream limit check. (cff_parse_num, do fixed, cff_parse_fixed_dynamic): Update callers. |
