Libpng 1.6.33 - September 28, 2017 This is a public release of libpng, intended for use in production codes. Files available for download: Source files with LF line endings (for Unix/Linux) and with a "configure" script libpng-1.6.33.tar.xz (LZMA-compressed, recommended) libpng-1.6.33.tar.gz Source files with CRLF line endings (for Windows), without the "configure" script lpng1633.7z (LZMA-compressed, recommended) lpng1633.zip Other information: libpng-1.6.33-README.txt libpng-1.6.33-LICENSE.txt libpng-1.6.33-*.asc (armored detached GPG signatures) Changes since the last public release (1.6.32): Added PNGMINUS_UNUSED macro to contrib/pngminus/p*.c and added missing parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse). Fixed off-by-one error in png_do_check_palette_indexes() (Bug report by Mick P., Source Forge Issue #269). Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc to fix shortlived oss-fuzz issue 3234. Compute a larger limit on IDAT because some applications write a deflate buffer for each row (Bug report by Andrew Church). Use current date (DATE) instead of release-date (RDATE) in last changed date of contrib/oss-fuzz files. Enabled ARM support in CMakeLists.txt (Bernd Kuhls). Fixed incorrect typecast of some arguments to png_malloc() and png_calloc() that were png_uint_32 instead of png_alloc_size_t (Bug report by "irwir" in Github libpng issue #175). Use pnglibconf.h.prebuilt when building for ANDROID with cmake (Github issue 162, by rcdailey). Initialize memory allocated by png_inflate to zero, using memset, to stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2() due to truncated iTXt or zTXt chunk. Initialize memory allocated by png_read_buffer to zero, using memset, to stop an oss-fuzz "use of uninitialized value" detection in png_icc_check_tag_table() due to truncated iCCP chunk. Removed a redundant test (suggested by "irwir" in Github issue #180). Added an interlaced version of each file in contrib/pngsuite. Relocate new memset() call in pngrutil.c. Removed more redundant tests (suggested by "irwir" in Github issue #180). Add support for loading images with associated alpha in the Simplified API (Samuel Williams). Revert contrib/oss-fuzz/libpng_read_fuzzer.cc to libpng-1.6.32 state. Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc Add end_info structure and png_read_end() to the libpng fuzzer.
