- update to 1.6.30: Revised documentation of png_get_error_ptr() in the libpng manual. Document need to check for integer overflow when allocating a pixel buffer for multiple rows in contrib/gregbook, contrib/pngminus, example.c, and in the manual (suggested by Jaeseung Choi). This is similar to the bug reported against pngquant in CVE-2016-5735. Check for integer overflow in contrib/visupng and contrib/tools/genpng. Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt. Avoid writing an empty IDAT when the last IDAT exactly fills the compression buffer (bug report by Brian Baird). This bug was introduced in libpng-1.6.0. Add a reference to the libpng.download site in README.

- update to 1.6.29: Moved SSE2 optimization code into the main libpng source directory. Configure libpng with "configure --enable-intel-sse" or compile libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it. Added code for PowerPC VSX optimisation (Vadim Barkov). Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).

- update to 1.6.26: Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo, bugfix by John Bowler). Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL has allocated memory that libpng needs to free. Issue a png_benign_error instead of a png_error on ADLER32 mismatch while decoding compressed data chunks. Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and pngrutil.c. If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE, ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs. Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error(). Updated the documentation about CRC and ADLER32 handling. Fixed offsets in contrib/intel/intel_sse.patch Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h to avoid a signed/unsigned compare in the preprocessor. Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to optionally avoid ADLER32 evaluation.

- update to 1.6.24: Avoid potential overflow of the PNG_IMAGE_SIZE macro. Correct filter heuristic overflow handling. Use a more efficient absolute value calculation on SSE2. Added pngcp. etc. see ANNOUNCE - Update to new upstream release 1.6.23 * Fixes a potential memleak in png_set_tRNS. * Fixed the progressive reader to handle empty first IDAT chunk properly. * Added tests in pngvalid.c to check zero-length IDAT chunks in various positions. * Fixed the sequential reader to handle these more robustly. * Corrected progressive read input buffer in pngvalid.c. * Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch. * Fixed undefined behavior in png_push_save_buffer(). Do not call memcpy() with a null source, even if count is zero. * Fixed bad link to RFC2083 in png.5.

- update to 1.6.22: Added a png_image_write_to_memory() API and a number of assist macros to allow an application that uses the simplified API write to bypass stdio and write directly to memory. Relaxed limit checks on gamma values in pngrtran.c. As suggested in the comments gamma values outside the range currently permitted by png_set_alpha_mode are useful for HDR data encoding. These values are already permitted by png_set_gamma so it is reasonable caution to extend the png_set_alpha_mode range as HDR imaging systems are starting to emerge. Restored "& 0xff" in png_save_uint_16() and png_save_uint_32() that were accidentally removed from libpng-1.6.17. Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h (Robert C. Seacord). Added INTEL-SSE2 support (Mike Klein and Matt Sarett, Google, Inc.). SSE filter speed improvements for bpp=3: memcpy-free implementations of load3() / store3(). Added PNG_FAST_FILTERS macro (defined as PNG_FILTER_NONE|PNG_FILTER_SUB|PNG_FILTER_UP).

- update to 1.6.20: Avoid potential pointer overflow/underflow in png_handle_sPLT() and png_handle_pCAL() (Bug report by John Regehr). Fixed incorrect implementation of png_set_PLTE() that uses png_ptr not info_ptr, that left png_set_PLTE() open to the CVE-2015-8126 vulnerability. Backported tests from libpng-1.7.0beta69. Fixed an error in handling of bad zlib CMINFO field in pngfix, found by American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't immediately fault a bad CMINFO field; instead a 'too far back' error happens later (at least some times). pngfix failed to limit CMINFO to the allowed values but then assumed that window_bits was in range, triggering an assert. The bug is mostly harmless; the PNG file cannot be fixed. In libpng 1.6 zlib initialization was changed to use the window size in the zlib stream, not a fixed value. This causes some invalid images, where CINFO is too large, to display 'correctly' if the rest of the data is valid. This provides a workaround for zlib versions where the error arises (ones that support the API change to use the window size in the stream).

- update to 1.6.19: Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c Fixed uninitialized variable in contrib/gregbook/rpng2-x.c Fixed the recently reported 1's complement security issue. Fixed png_save_int_32 when int is not 2's complement by replacing the value that is illegal in the PNG spec, in both signed and unsigned values, with 0. etc., see ANNOUNCE and CHANGES for details - removed: libpng-rgb_to_gray-checks.patch (upstreamed)

- Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. + libpng-rgb_to_gray-checks.patch - updated to 1.6.17: Corrected the width limit calculation in png_check_IHDR(). Removed user limits from pngfix. Also pass NULL pointers to png_read_row to skip the unnecessary row de-interlace stuff. Implement previously untested cases of libpng transforms in pngvalid.c Fixed byte order in 2-byte filler, in png_do_read_filler(). Made the check for out-of-range values in png_set_tRNS() detect values that are exactly 2^bit_depth, and work on 16-bit platforms. Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47. Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and pngset.c to avoid warnings about dead code. Do not build png_product2() when it is unused. Display user limits in the output from pngtest. Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column and 1-million-row default limits in pnglibconf.dfa, that can be reset by the user at build time or run time. This provides a more robust defense against DOS and as-yet undiscovered overflows. Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default. Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins). Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block of png.h. Free the unknown_chunks structure even when it contains no data. Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha value was wrong. It's not clear if this affected the final stored value; in the obvious code path the upper and lower 8-bits of the alpha value were identical and the alpha was truncated to 8-bits rather than dividing by 257 (John Bowler).
