fbe2fe4c | 2017-05-29 13:29:28 | Handle some integer overflow run-time errors (#46149, #48979). This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. | |
|
2e4188d8 | 2017-05-28 07:46:22 | [cff] s/cf2_floatToFixed/cf2_doubleToFixed/. The new name better describes what the macro actually does; additionally, we don't need a trailing `f' for literals (there was only a single such instance in the code, but this caused a clang warning because the macro itself uses `double' literals). * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, src/cff/cf2font.c, src/cff/cf2hints.c: Updated. | |
|
93572190 | 2017-05-28 07:20:09 | Fix negation of INT_MIN and LONG_MIN (#46149). * src/base/ftcalc.c (FT_MOVE_SIGN): Add argument to pass unsigned value, to be used as the result. (FT_MulDiv, FT_MulDiv_No_Round, FT_DivFix, FT_MulFix, FT_Vector_NormLen): Updated. | |
|
a9331c0f | 2017-05-27 15:50:25 | [truetype] Fix handling of design coordinates (#51127). * src/truetype/ttgxvar.c (tt_set_mm_blend): Compute all design coordinates if we have to create the `blends->coord' array. (TT_Get_MM_Blend, TT_Get_Var_Design): Select default instance coordinates if no instance is selected yet. | |
|
082f2faf | 2017-05-24 07:40:46 | [bdf, pcf] Support ISO646.1991-IRV character encoding (aka ASCII). Problem reported by Marek Kašík <mkasik@redhat.com>, cf. https://bugzilla.redhat.com/show_bug.cgi?id=1451795 * src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdrivr.c (PCF_Face_Init): Implement it. | |
 |
a0455468 | 2017-05-20 07:28:46 | [truetype] Always use interpreter v35 for B/W rendering (#51051). * src/truetype/ttgload.c (tt_loader_init) [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Adjust `subpixel_hinting_lean', `grayscale_cleartype', and `vertical_lcd_lean' accordingly. * src/truetype/ttinterp.c (Ins_GETINFO): Updated. (TT_RunIns): Update `backward_compatibility' flag. | |
 |
ab2599ea | 2017-05-20 00:35:21 | [smooth] Implement minimal dynamic padding for LCD filtering. Extra bitmap padding for LCD filtering depends on the filter. The default 5-tap filter needs 2 extra subpixels. The light 3-tap filter needs only 1 extra subpixel. This space could be already available due to rounding. In order to optimize the padding, we now expand CBox for the given filter weights before rounding. This change breakes current Skia (and Firefox). * include/freetype/internal/ftobjs.h (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Remove `lcd_extra' field. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights, FT_Library_SetLcdFilter): Remove `lcd_extra' initializations. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Implement dymanic LCD padding. | |

|
a7f276a2 | 2017-05-15 00:25:37 | [autofit] Make autohint warping NORMAL option. This moves warping option from LIGHT to NORMAL mode. This makes LIGHT truly void of hinting in x-direction, with left side bearing never changed and right side bearing only altered by advance rounding. Therefore, LIGHT is now ready to return fractional advance. As a NORMAL option, warping substitutes normal hinting. * src/autofit/afcjk.c (af_cjk_hints_apply): Updated. * src/autofit/aflatin.c (af_latin_hints_apply): Updated. * src/autofit/aflatin2.c (af_latin2_hints_apply): Updated. * src/autofit/afloader.c (af_loader_load_glyph): Handle warping phantom points as normal. | |

60bf264e | 2017-05-02 14:38:54 | [truetype] Make `IUP' gvar deltas do the same as Apple (#50832). When points are not touched by gvar interpolation deltas, FreeType gave a slightly different result than Apple's CoreText. The OpenType working group will update the specification to document the following behaviour: If the two points with deltas to the `left' and `right' of the untouched point have the same coordinate, then the inferred delta for the untouched point should be zero. * src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new behaviour. | |

5aa6716a | 2017-04-22 13:27:21 | Add new `slight' auto-hinting mode. This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backwards compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. (FT_RENDER_MODE_SLIGHT): New render mode. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add `autohint_mode' and `autohint_metrics' fields. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): Updated. * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use `autohint_metrics'. (af_loader_load_glyph): s/internal/slot_internal/. Initialize `autohint_metrics' and `autohint_mode' depending on current auto-hint mode. Use `autohint_metrics'.

(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. | |
|
e7b01304 | 2017-04-02 22:01:47 | [autofit] Disable metrics adjustment for `FT_LOAD_TARGET_LCD'. * src/autofit/aflatin.c (af_latin_hints_init): Updated. * src/autofit/aflatin2.c (af_latin2_hints_init): Ditto. | |

|
bcc74f4d | 2017-03-30 13:14:43 | [truetype] Allow linear scaling for unhinted rendering (#50470). * 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. | |
|
1ede3674 | 2017-03-30 00:26:31 | [truetype] Fix thinko related to PS name of default named instance. * src/truetype/ttgxvar.c (TT_Get_MM_Var): `strid' and `psid' are name ID values, not indices into the array of name entries. | |
|
4c1b5dc1 | 2017-03-27 21:00:17 | s/index/idx/ where appropriate. | |
|
208e712d | 2017-03-27 20:56:23 | [cid, truetype] Don't use `index' as a variable name. 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. | |
 |
565f5a7d | 2017-03-27 09:19:14 | [sfnt] Minor improvement for handling kern tables. * 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.

|
f958c48e | 2017-03-24 09:15:10 | [psaux] Better protect `flex' handling. Reported as 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. | |
|
913f436d | 2017-03-23 18:37:06 | [sfnt] Fix check for default named instance. * src/sfnt/sfobjs.c (sfnt_init_face): A `fixed' number needs four bytes, not two... | |
|
67ff7664 | 2017-03-23 12:41:30 | Make MM fonts work (again). * 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. | |
|
683e3ad9 | 2017-03-21 19:49:11 | [truetype] Some variable renamings. 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/.

|
3e79254a | 2017-03-18 10:06:15 | * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#50573). The problematic font that exceeds the old limit is Lato-Regular, version 2.007, containing bytecode generated by a buggy version of ttfautohint. | |
|
13fa85a2 | 2017-03-18 09:42:58 | [truetype] Another limitation for bytecode loop count maximum. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=900 * src/truetype/ttinterp.c (TT_RunIns): Limit `loopcall_counter_max' by number of glyphs also. | |
|
ab840e6a | 2017-03-18 08:50:42 | [ftfuzzer] Minor improvement. * src/tools/ftfuzzer/ftfuzzer.cc: Don't set intermediate axis if bitmap strikes are active. | |
