Here are the details from the Slackware 12.0 ChangeLog:
+--------------------------+
patches/packages/libpng-1.2.27-i486-1_slack12.0.tgz:
 Upgraded to libpng-1.2.27.
 This fixes various bugs, the most important of which have to do with the
 handling of unknown chunks containing zero-length data. Processing a PNG
 image that contains these could cause the application using libpng to crash
 (possibly resulting in a denial of service), could potentially expose the
 contents of uninitialized memory, or could cause the execution of arbitrary
 code as the user running libpng (though it would probably be quite difficult
 to cause the execution of attacker-chosen code). We recommend upgrading the
 package as soon as possible.
