It sometimes produced too small of a window. - Reject all iCCP chunks after the first, even if the first one is invalid. - Added palette-index checking. Issue a png_benign_error() if an invalid - index is found. - Revised example.c to put text strings in a temporary character array - instead of directly assigning string constants to png_textp members. - This avoids compiler warnings when -Wwrite-strings is enabled. - Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice. - Revised png_set_text_2() to avoid potential memory corruption (fixes - CVE-2011-3048). + Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h + 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. + Added testing of png_set_packing() to pngvalid.c + Regenerated configure scripts in the *.tar distributions with libtool-2.4.4 + 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). + Rebuilt configure scripts with automake-1.15 and libtool-2.4.6 + Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block + of png.h. + Avoid runtime checks when converting integer to png_byte with + Visual Studio (Sergey Kosarevsky) + Removed some comments that the configure script did not handle + properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt. + Free the unknown_chunks structure even when it contains no data. + Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF + for consistency, and remove some useless tests (Alexey Petruchik). + Remove pnglibconf.h, pnglibconf.c, pnglibconf.pre, pnglibconf.dfn, + and pnglibconf.out instead of pnglibconf.* in "make clean" (Cosmin). + 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).
