Major bugfixes:
* Fixed encode from dwg and json for many objects: missing size and bitsize
recalculation for objects with strings and DD types. (GH #322, #326)
* dwgadd: Fixed the pspace command. (GH #319)
* Missed all binary DXF groups 0. Still not working, but added to oss-fuzz.
* Support older gperf, older than 3.1. eg. macOS
LibreDWG version 0.12.3 - 2021/02/26 - beta:
Minor bugfixes:
* Fixed many more minor fuzzer errors, detected with the new llvmfuzz.
* Harmonize UBSAN access for unaligned shorts (unicode strings).
Wrong only with UBSAN or HAVE_ALIGNED_ACCESS_REQUIRED.
* Fix dwg2dxf/dxf2dwg uppercase extension problem (Windows) (GH #311).
* Fix section_string_stream offset for r2010 beta 2 (many public samples) (GH #318)
Minor features:
* Added google oss-fuzz integration, by David Korczynski (PR #316)
libredwg is now fuzzed twice daily.
* Added examples/llvmfuzz for libfuzzer and the google oss-fuzz service.
LibreDWG version 0.12.2 - 2021/02/23 - beta:
Minor bugfixes:
* Fixed extending the write buffer for the 2 CRC bytes. Occurs very
seldomly (GH #315)
LibreDWG version 0.12.1 - 2021/01/31 - beta:
Major bugfixes:
* fixed dwg_bmp() and dwgbmp for >= r2004. Wrong dat offset.
* Fixed EED with code 3 for layer handles. (Fixes GH #310, shanzhugit)
* Fixed bit_convert_TU utf8 conversion with ubsan, wrong endian-ness.
Various fuzzing errors detected and fuzzed by Chew Kin Zhong (See GH #304):
* Fix possible null-deref with broken DWG's in dwg_get_first_object.
* Fix possible null-deref with broken DWG's in dwg_find_class with empty
CLASS.dxfname. (GH #309)
* Fix possible null-deref with broken DWG's in dwglayers with empty
LAYER.name. (GH #308)
* Fix short integer overflow in EED checks when decoding malcrafted DWG's,
which also led to encode buffer overflows. (GH #307)
* Fix possible null-derefs with broken DWG's in json export. (GH #306)
* Fix possible null-deref with broken DWG's in dwg_next_entity iterator. (GH #305)
* Fix wrong TFF overflow check for static strings, where we cannot set
the string nor the size. (GH #304)
* Fix heap-overflows and invalid free's when decoding broken 3DSOLID's
in malcrafted DWG's. Only accept version 1 and 2. (GH #304)
Minor features:
* Added string converters with known TU sizes: bit_TU_to_utf8_len, bit_read_TU_len.
