Libpng 1.4.22 - 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-1.4.22.tar.xz (LZMA-compressed, recommended) libpng-1.4.22.tar.gz Source files with CRLF line endings (for Windows), without the "configure" script lpng1422.7z (LZMA-compressed, recommended) lpng1422.zip Other information: libpng-1.4.22-README.txt libpng-1.4.22-LICENSE.txt libpng-1.4.22-*.asc (armored detached GPG signatures) Changes since the last public release (1.4.21): Added PNGMINUS_UNUSED macro to contrib/pngminus/p*.c and added missing parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse). Compute a larger limit on IDAT because some applications write a deflate buffer for each row (Bug report by Andrew Church). 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). 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.
