suzuki toshiya fb5268cf 2015-09-28T02:01:43 [base] Fix a leak by broken sfnt-PS or resource fork (#46028). open_face_from_buffer() frees passed buffer if valid font is not found. But if copying to the buffer is failed, the allocated buffer should be freed within the caller. * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free the buffer `sfnt_ps' if an error caused before calling open_face_from_buffer(). (Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if an error caused before calling open_face_from_buffer();
suzuki toshiya 8a05d250 2015-09-28T01:40:21 [mac] Fix buffer size calculation for LWFN font. * src/base/ftmac.c (read_lwfn): Cast post_size to FT_ULong to prevent confused copy by too large chunk size.

Werner Lemberg 2439c515 2015-09-25T16:54:28 [type1] Protect against invalid number of glyphs (#46029). * src/type1/t1load.c (parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream.
Werner Lemberg 5339c75e 2015-09-24T13:39:44 [sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs.
Werner Lemberg c409eb18 2015-09-24T12:39:38 [base, sfnt] Better checks for invalid cmaps (1/2). * src/base/ftobjs.c (FT_Get_Char_Index): Don't return out-of-bounds glyph indices. (FT_Get_First_Char): Updated. * src/sfnt/ttcmap.c (tt_cmap6_char_next): Don't return character codes greater than 0xFFFF. (tt_cmap8_char_index): Avoid integer overflow in computation of glyph index.

Werner Lemberg cbdf13e5 2015-09-24T12:14:38 Formatting, documentation improvements.
suzuki toshiya e982f5b7 2015-09-21T23:07:22 [base] Check too long POST and sfnt resource (#45919). * src/base/ftbase.h (FT_MAC_RFORK_MAX_LEN): Maximum length of the resource fork for Mac OS. The resource fork larger than 16 MB can be written but could not be handled correctly, at least in Carbon routine. See https://support.microsoft.com/en-us/kb/130437 * src/base/ftobjs.c (Mac_Read_POST_Resource): No need `0x' for `%p' formatter. * src/base/ftbase.c (Mac_Read_POST_Resource): Check the fragment and total size of the concatenated POST resource before buffer allocation. (Mac_Read_sfnt_Resource): Check the declared size of sfnt resource before buffer allocation. * src/base/ftmac.c (read_lwfn, FT_New_Face_From_SFNT): Check the total resource size before buffer allocation.
Werner Lemberg 730b6d74 2015-09-19T12:41:12 [sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.
Werner Lemberg cb7a5122 2015-09-19T07:58:03 [pcf] Improve `FT_ABS' fix from 2015-09-17 (#45999). * src/pcf/pcfread.c (pcf_load_font): Do first the cast to FT_Short, then take the absolute value. Also apply FT_ABS to `height'.
Werner Lemberg f28c95c4 2015-09-17T19:30:26 [type42] Fix memory leak (#45989). * src/type42/t42parse.c (t42_parse_charstrings): Allow only a single `CharStrings' array.
Werner Lemberg 4942c2bb 2015-09-17T17:56:53 [psaux] Fix memory leak (#45986). * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_MM_BBOX>: Free `temp' in case of error.

Werner Lemberg 7962a15d 2015-09-14T00:38:26 [type1] Fix another potential buffer overflow (#45955). * src/type1/t1parse (T1_Get_Private_Dict): Assure that check for `eexec' doesn't exceed `limit'.
Werner Lemberg ff7d6404 2015-09-13T23:53:16 Replace `mkinstalldirs' with AC_PROG_MKDIR_P. * builds/unix/mkinstalldirs: Removed, no longer needed. * builds/unix/configure.raw: Call `AC_PROG_MKDIR_P'. Update pwd call for `$INSTALL'. * builds/unix/unix-def.in (MKINSTALLDIRS): Use `@MKDIR_P@'. * autogen.sh: Updated.

Werner Lemberg e3058617 2015-09-13T08:41:43 [type1] Fix potential buffer overflow (#45923). * src/type1/t1parse.c (T1_Get_Private_Dict): Assure `cur' doesn't point to end of file buffer.
Werner Lemberg e40e8b33 2015-09-13T08:05:50 [gzip] Fix access of small compressed files (#45937). * src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak. (ft_gzip_get_uncompressed_file): Correct byte order while reading unsigned long value. Without this change, the whole optimization of accessing small files in `FT_Stream_OpenGzip' is never executed! As a consequence, access to PCF files in general (which are normally small files) should be much improved now as originally intended.
Werner Lemberg db5a4a9a 2015-09-12T08:32:55 [psaux] Fix potential buffer overflow (#45922). * src/psaux/psobjs.c (ps_parser_skip_PS_token): If a token is enclosed in balanced expressions, ensure that the cursor position doesn't get larger than the current limit.

Wojciech Mamrak 822acb02 2015-09-09T07:59:10 * src/base/ftcalc.c (FT_CeilFix, FT_FloorFix): Normalize. This commit makes the functions behave as expected, this is, rounding towards plus or minus infinity.
Wojciech Mamrak 5578199a 2015-09-09T07:52:17 Minor documentation corrections.
Alexei Podtelezhnikov b002f688 2015-09-07T13:47:36 * src/smooth/ftgrays.c (gray_render_line): Simplify clipping.
Alexei Podtelezhnikov 5a6dc872 2015-09-04T23:14:46 [raster,smooth] Microoptimizations. * src/raster/ftraster.c (Insert_Y_Turn, Finalize_Profile_Table, Beziier_Up, ): Use do-while loops. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line, gray_convert_glyph): Ditto.
Alexei Podtelezhnikov a9f6f04e 2015-09-04T22:28:13 [autofit] Missing piece.
Werner Lemberg d3cba0ed 2015-09-04T10:28:53 [autofit] Redesign code ranges (2/2). This commit adds two fallback scripts (`latb', `latp') and implements support for the no-base character ranges introduced in the previous commit. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `script_uni_nobase_ranges' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and `latp' fallback scripts. * src/autofit/afblue.dat: Add blue zones for Latin subscript and superscript fallback scripts. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base characters.

Werner Lemberg 696b7126 2015-09-04T10:10:59 [autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.
Werner Lemberg 8cbbcf6b 2015-09-03T06:47:30 [autofit] Pass glyph index to hinting function. No functionality change yet. * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Pass glyph index. * src/autofit/afcjk.c, src/autofit/afcjk.h (af_cjk_hints_apply), src/autofit/afdummy.c (af_dummy_hints_apply), src/autofit/afindic.c (af_indic_hints_apply), src/autofit/aflatin.c (af_latin_hints_apply), src/autofit/aflatin2.c (af_latin2_hints_apply), src/autofit/afloader.c (af_loader_load_g): Updated.
Werner Lemberg 40103a3a 2015-08-31T08:51:52 [autofit] Code clean-up. * src/autofit/afglobal.h (AF_STYLE_MASK): New macro. (AF_STYLE_UNASSIGNED): Use AF_STYLE_MASK for definition. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Updated.
Werner Lemberg 87c81f04 2015-08-30T10:35:21 [autofit] Make glyph style array use 16bit values. * include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use `FT_UShort' for `map' field. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage, af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h (af_get_coverage): Use FT_UShort for `glyph_styles' array. * src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to 16 bits. (AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.

Werner Lemberg 14d6b5d7 2015-08-13T15:22:17 [truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks.

Alexei Podtelezhnikov 4a466865 2015-08-12T23:45:40 [type1,cff,cid] Streamline font matrix application. * src/type1/t1gload.c (T1_Load_Glyph): Directly modify advances only if font matrix is not trivial. * src/cff/cffgload.c (cff_slot_load): Ditto. * sff/cid/cidgload.c (cid_slot_load_glyph): Ditto for advances and the entire outline.
Werner Lemberg 7ebe6ac8 2015-08-11T06:47:25 [builds/unix] Minor. * builds/unix/configure.raw: s/lib{priv,staticconf}/libs{priv,staticconf}/ for orthogonality with similarly named uppercase variables.
Alexei Podtelezhnikov a37da21a 2015-08-10T23:05:02 [type1,cid,type42] Minor improvements. * src/type1/t1load.c (t1_parse_font_matrix): Scale units per EM only when necessary.

Werner Lemberg bd75a517 2015-08-08T08:39:45 [type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.
Werner Lemberg e5f44693 2015-08-08T07:45:03 [type42] Minor clean-up. * src/type42/t42parse.c (t42_parse_font_matrix): Remove unused variable.

Werner Lemberg ff406e2e 2015-08-06T07:34:50 [autofit] Improve Arabic hinting. Problem reported by Titus Nemeth <tn@tntypography.eu> (by using ttfautohint). * src/autofit/afblue.dat: Add neutral blue zone for the tatweel character. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
Alexei Podtelezhnikov 98e8e999 2015-08-06T00:06:14 [truetype] Clean up types. * src/truetype/ttobjs.c (TT_Size): Move declaration from here. * include/freetype/internal/tttypes.h (TT_Size): ... to here. (TT_LoaderRec): Switch to appropriate types for `face' and `size'. * src/truetype/ttgload.c: Remove corresponding type casts. * src/truetype/ttsubpix.c: Ditto.
Werner Lemberg 15e2a4f7 2015-08-05T21:53:50 [autofit] Improve recognition of flat vs. rounded segments. Lower the flatness threshold from upem/8 to upem/14, making the auto-hinter accept shorter elements. Synchronize flat/round stem selection algorithm with blue zone code. * src/autofit/aflatin.c (FLAT_THRESHOLD): New macro. (af_latin_metrics_init_blues): Use it. (af_latin_hints_compute_segments): Collect information on maximum and minimum coordinates of `on' points; use this to add a constraint for the flat/round decision similar to `af_latin_metrics_init_blues'.
Werner Lemberg eb22ef26 2015-08-04T06:50:04 Another left-shift bug (#45681). * src/base/ftobjs.c (IsMacBinary): Only accept positive values for `dlen'.
Alexei Podtelezhnikov 7e6c321a 2015-08-03T23:26:13 [base] Fix `ft_corner_orientation'. Remove casting from `FT_Long' to `FT_Int' that might change the sign of the return value and make it faster too. * src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay with 32-bit arithmetic when safe. Use plain math on 64-bit systems. * src/pshinter/pshalgo.c: Remove old unused code.
Werner Lemberg 8dfc7601 2015-08-03T12:23:30 * src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Fix crash for composite glyphs having a depth greater than 1.
Werner Lemberg ca6a5cf4 2015-08-03T08:51:18 Fix typo in clang bug from 2015-07-31 (#45678). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Fix inequality.
Werner Lemberg a82c45d5 2015-08-02T18:35:49 * CMakeLists.txt: Improve shared library support. Based on a patch from John Cary <cary@txcorp.com>.
Werner Lemberg 682c2719 2015-08-02T15:46:26 * builds/unix/freetype-config.in (enable_shared): Remove. Unused.

Werner Lemberg 70e9d815 2015-08-02T09:42:12 Fix more invalid left-shifts. * src/pfr/pfrgload.c (pfr_glyph_load_compound): Use multiplication, not left-shift. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Use multiplication, not left-shift.
Werner Lemberg 6343ba22 2015-08-01T07:53:48 Fix some bugs found by clang's `-fsanitize=undefined' (#45661). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Only accept positive values from header. Check overflow. * src/base/ftoutln.c (SCALED): Correctly handle left-shift of negative values. * src/bdf/bdf.h (_bdf_glyph_modified, _bdf_set_glyph_modified, _bdf_clear_glyph_modified): Use unsigned long constant. * src/bdf/bdfdrivr.c (BDF_Size_Select, BDF_Glyph_Load): Don't left-shift values that can be negative. * src/pcf/pcfdrivr.c (PCF_Size_Select, PCF_Glyph_Load): Don't left-shift values that can be negative. * src/raster/ftraster.c (SCALED): Correctly handle left-shift of negative values. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Don't left-shift values that can be negative. * src/truetype/ttgload.c (TT_Load_Composite_Glyph, compute_glyph_metrics, load_sbit_image): Don't left-shift values that can be negative.
Werner Lemberg 5d1b8ab4 2015-07-31T21:49:07 Define FT_LONG_MAX. * include/freetype/config/ftstdlib.h (FT_LONG_MAX): New macro. * src/cff/cf2arrst.c (cf2_arrstack_setNumElements): Use it.
Alexei Podtelezhnikov 2b07a5ae 2015-07-28T23:14:30 * src/base/ftcalc.c (FT_Vector_NormLen): Clarify.
Werner Lemberg a50a0458 2015-07-28T07:37:19 Minor.
