- version update to 1.6.43
* Fixed the row width check in png_check_IHDR().
This corrected a bug that was specific to the 16-bit platforms,
and removed a spurious compiler warning from the 64-bit builds.
(Reported by Jacek Caban; fixed by John Bowler)
* Added eXIf chunk support to the push-mode reader in pngpread.c.
(Contributed by Chris Blume)
* Added contrib/pngexif for the benefit of the users who would like
to inspect the content of eXIf chunks.
* Added contrib/conftest/basic.dfa, a basic build-time configuration.
(Contributed by John Bowler)
* Fixed a preprocessor condition in pngread.c that broke build-time
configurations like contrib/conftest/pngcp.dfa.
(Contributed by John Bowler)
* Added CMake build support for LoongArch LSX.
(Contributed by GuXiWei)
* Fixed a CMake build error that occurred under a peculiar state of the
dependency tree. This was a regression introduced in libpng-1.6.41.
(Contributed by Dan Rosser)
* Marked the installed libpng headers as system headers in CMake.
(Contributed by Benjamin Buch)
* Updated the build support for RISCOS.
(Contributed by Cameron Cawley)
* Updated the makefiles to allow cross-platform builds to initialize
conventional make variables like AR and ARFLAGS.
* Added various improvements to the CI scripts in areas like version
consistency verification and text linting.
* Added version consistency verification to pngtest.c also.

missing parenthesis in contrib/pngminus/pnm2png.c

changed date of contrib/oss-fuzz files.

memset, to stop an oss-fuzz "use of uninitialized value"

memset, to stop an oss-fuzz "use of uninitialized value"

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
* Replaced local eXIf_buf with info_ptr-eXIf_buf in png_handle_eXIf().

* 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 (Fixes CVE-2017-12652)
* 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).
* Revised symlink creation, no longer using deprecated cmake
LOCATION feature
* Fixed five-byte error in the calculation of IDAT maximum
possible size.
* Moved chunk-length check into a png_check_chunk_length()
private function
* Moved bad pngs from tests to contrib/libtests/crashers
* Moved testing of bad pngs into a separate
tests/pngtest-badpngs script

writes XFAIL in the output but PASS for the libpng test.
* Require cmake-3.0.2 in CMakeLists.txt
* Fix "const" declaration info_ptr argument to png_get_eXIf_1()
and the num_exif argument to png_get_eXIf_1()
* 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
* Added contrib/oss-fuzz directory which contains files used by
the oss-fuzz project
