c357fb70b5 [lbipng15] Fixed the recently reported 1's complement security issue by 
replacing the value that is illegal in the PNG spec, in both signed and
  unsigned values, with 0. Illegal unsigned values (anything greater than or
  equal to  0x80000000) can still pass through, but since these are not illegal
  in ANSI-C (unlike 0x80000000 in the signed case) the checking that
  occurs later can catch them (John Bowler).

Safely convert num_bytes to a png_byte in png_set_sig_bytes() (Robert
  Seacord).

71fcb39efc [libpng15] Merged pngvalid and pngtest from libpng-1.5; made compressed chunks 
after IDAT work with the progressive read code (this is a minor and
somewhat ugly fix-up; the proper fix is in 1.6).

ec89c54e42 [libpng16] Choose to use windowBits==15 or the zlib header setting via the 
benign-errors setting.  If benign errors are allowed, then ignore
the windowBits setting in the zlib header.
Zlib-1.2.8 and earlier don't allow us to decrease the windowBits, so
undid the improvement in beta04.
