|
1e2eb650 | 2022-03-07 10:13:29 | Documentation, whitespace. | |
 |

335224be | 2022-03-03 16:33:40 | [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 | |
|
034e5dbf | 2022-02-22 20:37:43 | [psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259 | |
 |
bcdfa386 | 2022-02-20 23:55:32 | [cmake] Drop the support of CMake 2.x. * CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer. The issue #1059 reports the difficulty to support both of CMake 2.x and newer one by single CMakeLists.txt without the inflation of cmake_policy() workarounds. For better maintainability, the support of CMake 2.x is dropped. | |
|
6c5522c6 | 2022-02-19 13:37:07 | * src/bdf/README: Updated. | |
|
ca46bc0c | 2022-02-19 13:34:05 | * builds/mac/ftmac.c, src/base/ftmac.c: s|FT_MAC_H|<freetype/ftmac.h>|. | |
|
5b26e92a | 2022-02-19 05:26:53 | src/sfnt/ttkern.c (tt_face_load_kern): Micro-optimize. A kerning table can be handled by binary search if it has equal entries. Fixes #1132. | |
|
20ec99be | 2022-02-17 13:35:52 | [builds/windows] Add support for legacy UWP builds. * builds/windows/ftsystem.c: Add neccessary macro substitutions to enable strict UWP builds. See !141. Co-authored-by: Alexei Podtelezhnikov <apodtele@gmail.com> | |
|
01d4deb0 | 2022-02-16 14:21:00 | ftmm.h: Minor documentation improvement. | |
 |
00ae29fc | 2022-02-12 23:42:08 | [pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value. Before the change, the hinting engine frequently confused horizontal stem and serif hints making some stems too thin and some serifs too thick. The value was tuned using serif fonts from the URW+ base 35 collection. * src/pshinter/pshalgo.c [PSH_STRONG_THRESHOLD_MAXIMUM]: s/30/12/. | |
|
5a53e51b | 2022-02-12 07:58:43 | t1tables.h: Documentation improvements. | |
|
c67ecb8c | 2022-02-12 07:52:57 | t1tables.h: Whitespace. | |
|
338b4e88 | 2022-02-11 19:32:49 | [type42] Fix `FT_Get_PS_Font_Private` for this format. Since Type42 fonts don't have a 'Private' dictionary, the return value should be `FT_Err_Invalid_Argument`. * src/type42/t42drivr.c (t42_ps_get_font_private): Removed. (t42_service_ps_info): Updated. | |
|
1680885a | 2022-02-09 16:41:07 | [pshinter] Clear reused mask. In PS hinter, memory allocations persist until the module is done. Therefore, we have to clear reused masks. * src/pshinter/pshrec.c (ps_mask_table_alloc): Clear reused mask. | |
|
0447df71 | 2022-02-09 15:04:58 | [pshinter] Use unsigned indices. This reduces casting and eliminates some checks. * src/pshinter/pshrec.c (ps_mask_test_bit, ps_mask_table_merge, ps_dimension_add_t1stem, ps_hints_t1stem3): Updated. (ps_dimension_add_counter): Updated, unnecessary checks removed. | |
|
ed0e2e76 | 2022-02-08 16:35:14 | [pshinter] Fix mask merging. We forgot to update the number of bits when merging a larger mask into a smaller one. This fix might have rendering effects. * src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number of bits from a larger mask. There is no need to zero unused bits, already zeroed during allocation. (ps_mask_clear_bit): Removed. (ps_mask_ensure): Minor. | |
|
7c6b2f20 | 2022-02-08 14:37:34 | [pshinter] Revise the hint table handling. * src/pshinter/pshrec.c (ps_hint_table_ensure): Remove redundant size check; avoid array zeroing because it is fully initialized when used. (ps_hint_table_alloc): Fix off-by-one comparison and remove another zeroing of the array elements. | |
|

|
8e39e42e | 2022-02-02 11:35:14 | [psaux] Revise `PS_Table` handling. The old impleemntation was not using `FT_REALLOC`, buing too careful with the offset rebasing. It shoudl be safe to rely on the base movements. * src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine into... (ps_table_realloc): ... this function based on `FT_REALLOC`. (ps_table_done): Simplified. (ps_table_add): Updated. | |

|
35740aa6 | 2022-01-28 12:04:36 | [cmake] Check the availability of `bzip2.pc'. (CMakeLists.txt): Check the availability of `bzip2.pc'. * If `bzip2.pc' is available, Requires.private should include bzip2, but Libs.private should not include -lbz2. * If `bzip2.pc' is unavailable, Requires.private cannot include bzip2, but Libs.private should include -lbz2. Fix #897. | |
|
fa226478 | 2022-01-28 15:20:12 | * unix/configure.raw: We need 'librsvg' version 2.46.0 or newer. Older versions don't have function `rsvg_handle_get_intrinsic_dimensions`. | |

|
e34a860a | 2022-01-27 11:50:12 | Document `FT_Outline_Decompose` degenerate segments. `FT_Outline_Decompose` does not filter out and can return degenerate segments in an outline. This can be surprising when attemping to stroke such an outline. Clarify the existing documentation on this matter to cover all forms of degeneracy (without specifying exactly how they will be reported), why they might arise, and better explain in what cases they may be an issue. * include/freetype/ftoutlin.h (FT_Outline_Decompose): update documentation. Fixes #952. | |
 |
ab1c98ac | 2022-01-27 15:23:47 | Fix sdf computation while `USE_SQUARED_DISTANCES`. Function `map_fixed_to_sdf` expects spread to be absolute and not squared. * src/sdf/ftbsdf.c (finalize_sdf): Pass absolute spread while `map_fixed_to_sdf`. * src/sdf/ftsdf.c (sdf_generate_bounding_box): Ditto. | |
 |
3d77756e | 2022-01-27 08:34:48 | [sfnt] Improve sRGB constants. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Use slightly more precise values. Fixes #1018. | |

|
6a8e95b7 | 2022-01-25 08:49:41 | Update documentation for `FT_LOAD_COLOR`. | |
|
5e9caaee | 2022-01-24 12:19:20 | [pshinter] Ensure all point flags are initialized. Only off curve point flags were fully initialized. * src/pshinter/pshalgo.c (psh_glyph_init): always initialize flags. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43930 | |

|
06c1a25e | 2021-12-25 17:59:42 | Add flag `FT_CONFIG_OPTION_SVG`. This flag is going to be used to conditionally compile support for OT-SVG glyphs. FreeType will do the parsing and rely on external hooks for rendering of OT-SVG glyphs. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_SVG): New flag. | |

|
054782c4 | 2022-01-19 22:14:06 | [base] Undefined scale means no scale. It might be surprising that FreeType does not have default ppem and the size has to be set explicitly or face undefined behavior with undefined variables and errors. This offers an alternative to missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined behavior is bettr than undefined one. This is alternative to !132 and discussed in https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708 * src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale. * include/freetype/freetype.h: Document it. | |

6ee89519 | 2022-01-12 15:12:53 | [bzip2] Reset bzip stream on any error. According to the bzip documentation it is undefined what will happen if `BZ2_bzDecompress` is called on a `bz_stream` it has previously returned an error against. If `BZ2_bzDecompress` returns anything other than `BZ_OK` the only valid next action is `BZ2_bzDecompressEnd`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43564 * src/bzip2/ftbzip2.c (FT_BZip2FileRec_): Add `reset` to track the need to reset the stream. (ft_bzip2_file_init): Initialize `reset` to 0. (ft_bzip2_file_reset): Set `reset` to 0 after resetting. (ft_bzip2_file_fill_output): Set `reset` to 1 when `BZ2_bzDecompress` returns anything other than `BZ_OK`. | |

f1d3b9f1 | 2022-01-11 17:15:35 | Revert "[bzip2] Avoid use of uninitialized memory." This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6. The original commit did avoid the use of uninitialized memory. However, it appears that the original commit is no longer required. The underlying issue was resolved by a change in freetype2-testing "Build bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so bzip2 writes were not tracked or considered initialized. Clearing `buffer` in the original commit allowed msan to see the `buffer` content initialized once in FreeType code, but msan saw no writes into buffer from bzip2. With bzip2 now built with msan, the bzip2 writes are properly instrumented and msan sees the bzip2 writes into the buffer. As a result the original commit can be safely reverted to allow for better detection of other uninitialized data scenarios. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`.

e838c37c | 2022-01-11 11:14:32 | [type42] Track how much type42 ttf data is available. Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header data which it expects `t42_parse_sfnts` to fill out from /sfnts data. However, there is no guarantee that `t42_parse_sfnts` will actually be called while parsing the type42 data as the /sfnts array may be missing or very short. This is also confusing behavior as it means `T42_Open_Face` is tightly coupled to the implementation of the very distant `t42_parse_sfnts` code which requires at least 12 bytes to already be reserved in `face->ttf_data`. `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how much space is reserved for ttf data instead of traking how much data has actually been written into `face->ttf_data`. It will also act strangely in the presense of multiple /sfnts arrays. * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized to NULL. Free `ttf_data` on error. * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and set it to the actual number of bytes read. Ensure `ttf_data` is freed if there are multiple /sfnts arrays or there are any errors. | |
