-Changes since the last public release (1.6.31):
- Avoid possible NULL dereference in png_handle_eXIf when benign_errors
- are allowed. Avoid leaking the input buffer "eXIf_buf".
- Eliminated png_ptr->num_exif member from pngstruct.h and added num_exif
- to arguments for png_get_eXIf() and png_set_eXIf().
- Added calls to png_handle_eXIf(() in pngread.c and png_write_eXIf() in
- pngwrite.c, and made various other fixes to png_write_eXIf().
- Changed name of png_get_eXIF and png_set_eXIf() to png_get_eXIf_1() and
- png_set_eXIf_1(), respectively, to avoid breaking API compatibility
- with libpng-1.6.31.
- Updated contrib/libtests/pngunknown.c with eXIf chunk.
- Initialized btoa[] in pngstest.c
- Stop memory leak when returning from png_handle_eXIf() with an error
- (Bug report from the OSS-fuzz project).
- Replaced local eXIf_buf with info_ptr-eXIf_buf in png_handle_eXIf().
- Update libpng.3 and libpng-manual.txt about eXIf functions.
- Restored png_get_eXIf() and png_set_eXIf() to maintain API compatability.
- Removed png_get_eXIf_1() and png_set_eXIf_1().
- Check length of all chunks except IDAT against user limit to fix an
- OSS-fuzz issue.
- Check length of IDAT against maximum possible IDAT size, accounting
- for height, rowbytes, interlacing and zlib/deflate overhead.
- Restored png_get_eXIf_1() and png_set_eXIf_1(), because strlen(eXIf_buf)
- does not work (the eXIf chunk data can contain zeroes).
- Require cmake-2.8.8 in CMakeLists.txt. Revised symlink creation,
- no longer using deprecated cmake LOCATION feature (Clifford Yapp).
- Fixed five-byte error in the calculation of IDAT maximum possible size.
- Moved chunk-length check into a png_check_chunk_length() private
- function (Suggested by Max Stepin).
- Moved bad pngs from tests to contrib/libtests/crashers
- Moved testing of bad pngs into a separate tests/pngtest-badpngs script
- Added the --xfail (expected FAIL) option to pngtest.c. It writes XFAIL
- in the output but PASS for the libpng test.
- Require cmake-3.0.2 in CMakeLists.txt (Clifford Yapp).
- Fix "const" declaration info_ptr argument to png_get_eXIf_1() and the
- num_exif argument to png_get_eXIf_1() (Github Issue 171).
- Added "eXIf" to "chunks_to_ignore[]" in png_set_keep_unknown_chunks().
- Added huge_IDAT.png and empty_ancillary_chunks.png to testpngs/crashers.
- Make pngtest --strict, --relax, --xfail options imply -m (multiple).
- Removed unused chunk_name parameter from png_check_chunk_length().
- Relocated setting free_me for eXIf data, to stop an OSS-fuzz leak.
- Initialize profile_header[] in png_handle_iCCP() to fix OSS-fuzz issue.
- Initialize png_ptr->row_buf[0] to 255 in png_read_row() to fix OSS-fuzz UMR.
- Attempt to fix a UMR in png_set_text_2() to fix OSS-fuzz issue.
- Increase minimum zlib stream from 9 to 14 in png_handle_iCCP(), to account
- for the minimum 'deflate' stream, and relocate the test to a point
- after the keyword has been read.
- Check that the eXIf chunk has at least 2 bytes and begins with "II" or "MM".
- Added a set of "huge_xxxx_chunk.png" files to contrib/testpngs/crashers,
- one for each known chunk type, with length = 2GB-1.
- Check for 0 return from png_get_rowbytes() and added some (size_t) typecasts
- in contrib/pngminus/*.c to stop some Coverity issues (162705, 162706,
- and 162707).
- Renamed chunks in contrib/testpngs/crashers to avoid having files whose
- names differ only in case; this causes problems with some platforms
- (github issue #172).
- Added contrib/oss-fuzz directory which contains files used by the oss-fuzz
- project (https://github.com/google/oss-fuzz/tree/master/projects/libpng).
+Changes since the last public release (1.6.33):
+ Removed contrib/pngsuite/i*.png; some of these were incorrect and caused
+ test failures.
