Werner Lemberg 58b61b6e 2015-10-13T18:26:18 [pcf] Quickly exit if font index < 0. Similar to other font formats, this commit makes the parser no longer check the whole PCF file but only the header and the TOC if we just want to get the number of available faces (and a proper recognition of the font format). * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated.

Werner Lemberg 8de39a79 2015-10-10T13:34:11 [sfnt] Fix infinite loops with broken cmaps (#46167). * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next): Take care of border condidions (i.e., if the loops exit naturally).
Werner Lemberg da34673e 2015-10-10T10:21:27 [truetype] More sanity tests for GX handling. These tests should mainly help avoid unnecessarily large memory allocations in case of malformed fonts. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas): Check number of points against stream size. (ft_var_load_avar): Check `pairCount' against table length. (ft_var_load_gvar): Check `globalCoordCount' and `glyphCount' against table length.

Alexei Podtelezhnikov 6eb6158d 2015-10-06T22:39:54 [smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation.
Werner Lemberg 066a4913 2015-10-06T07:55:32 [cff] Return correct PS names from pure CFF (#46130). * src/cff/cffdrivr.c (cff_get_ps_name): Use SFNT service only for SFNT.

Werner Lemberg b260dc9f 2015-10-04T07:39:22 [bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_input), src/gzip/ftgzip.c (ft_gzip_file_fill_input): In case of an error, adjust the limit to avoid copying uninitialized memory.
Werner Lemberg 53838ce0 2015-10-03T21:12:25 [bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_output), src/gzip/ftgzip.c (ft_gzip_file_fill_output): In case of an error, adjust the limit to avoid copying uninitialized memory.
Alexei Podtelezhnikov e2dae8fe 2015-10-01T22:03:34 [smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove never used fields.
Werner Lemberg 90e437e3 2015-10-01T20:00:27 [sfnt] Make `tt_cmap4_char_map_linear' more robust (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Take care of border conditions (i.e., if the loop exits naturally).
Werner Lemberg feb1f138 2015-10-01T17:39:31 CHANGES: Updated.
Werner Lemberg fab67b85 2015-10-01T16:47:05 * src/autofit/afranges.c (af_deva_nonbase_uniranges): Fix ranges. They should be a subset of `af_deva_uniranges'.

Werner Lemberg dbd04269 2015-09-30T17:52:42 [autofit] Replace `no-base' with `non-base'. * src/autofit/*: Do it.
Werner Lemberg 2ff83a5c 2015-09-30T14:44:29 [sfnt] Rewrite `tt_cmap4_char_map_linear' (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Add code to better skip invalid segments. If searching the next character, provide a more efficient logic to speed up the code.

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.

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.

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.
