libpng-1.0.25 and libpng-1.2.17 are available at

These releases fix a vulnerability in png_handle_tRNS() by which
a malformed PNG file can crash a libpng application.  The bug has
existed since libpng-0.90.  The vulnerability is identified as
CVE-2007-2445 and CERT VU#684664.


Merging the changes was easy; it will be included in 1.40.4.
