Fixed off-by-one error in png_do_check_palette_indexes() (Bug report by Mick P., Source Forge Issue #269). Version 1.6.33beta02 [September 3, 2017] 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). Version 1.6.33beta03 [September 14, 2017] 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). Version 1.6.33rc01 [September 20, 2017] 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). Version 1.6.33rc02 [September 22, 2017] 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).
