68fb4789	2015-11-15T13:06:48	* src/autofit/afhints.c (af_get_segment_index): Fix it. The old code was too simple, returning invalid values in most cases where a segment crosses the contour start.

bcf618b2	2015-11-02T06:50:49	[ftfuzzer] Add support for multiple files (patch #8779). Currently, libFuzzer only supports mutation of a single file. We circumvent this problem by using an uncompressed tar archive as multiple-file input for the fuzzer. This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; a constructed tarball should contain a font file as the first element, and files to be attached as further elements. * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. (archive_read_entry_data, parse_data): New functions. (LLVMFuzzerTestOneInput): Updated. * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom mutator for libFuzzer that can mutate tarballs in a sensible way.

(tt_sbit_decoder_load_compound): Add argument for recursion depth. Increase recursion counter for recursive call. (tt_sbit_decoder_load_image): Add argument for recursion depth. Check recurse depth. (tt_face_load_sbit_image): Updated.

7f00fa64	2015-10-25T10:59:59	[autofit] Improve tracing. * src/autofit/afhints.c (af_print_idx, af_get_segment_index, af_get_edge_index): New functions. (af_glyph_hints_dump_points): Remove unnecessary `\|', `[', and `]'. Add segment and edge index for each point. Slightly change printing order of some elements. Don't print `-1' but `--' for missing elements. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove unnecessary `\|', `[', and `]'. Don't print `-1' but `--' for missing elements.

f1c93439	2015-10-22T10:11:23	[cff] Avoid overflow/module arithmetic. This modifies the addition of subroutine number to subroutine bias from unsigned to signed, but does not change any results. * src/cff/cf2ft.c (cf2_initGlobalRegionBuffer, cf2_initLocalRegionBuffer): Change variable names from (unsigned) `idx' to (signed) `subrNum', since it is not an index until after the bias is added. * src/cff/cf2ft.h: Updated. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: Updated similarly.
59ae73fe	2015-10-22T09:26:00	[cid] Better check of `SubrCount' dictionary entry (#46272). * src/cid/cidload.c (cid_face_open): Add more sanity tests for `fd_bytes', `gd_bytes', `sd_bytes', and `num_subrs'.

3eccc3a3	2015-10-20T22:31:57	[cid] Add a bunch of safety checks. * src/cid/cidload.c (parse_fd_array): Check `num_dicts' against stream size. (cid_read_subrs): Check largest offset against stream size. (cid_parse_dict): Move safety check to ... (cid_face_open): ... this function.

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.

2015-11-02T06:50:49

[ftfuzzer] Add support for multiple files (patch #8779). Currently, libFuzzer only supports mutation of a single file. We circumvent this problem by using an uncompressed tar archive as multiple-file input for the fuzzer. This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; a constructed tarball should contain a font file as the first element, and files to be attached as further elements. * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. (archive_read_entry_data, parse_data): New functions. (LLVMFuzzerTestOneInput): Updated. * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom mutator for libFuzzer that can mutate tarballs in a sensible way.

[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. Exit quickly if face_index < 0. * src/pcfread.c (pcf_load_font): Add `face_index' argument. Exit quickly if face_index < 0. * src/pcf/pcf.h: Updated.

(FT_Global): New class. Use it to provide a global constructor and destructor for the `FT_Library' object. (setIntermediateAxis): New function to select an (arbitrary) instance. (LLVMFuzzerTestOneInput): Loop over all faces and named instances. Also call `FT_Set_Char_Size'.

[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.
