libpng-1.0.40 and libpng-1.2.32 are available from ftp://ftp.simplesystems.org/pub/png/src/ and from http://libpng.sf.net, which seems to be broken right now but you can go directly to the download page at http://sourceforge.net/project/showfiles.php?group_id=5624 This release fixes a new bug that causes a crash when reading multiple zTXt chunks.
