Thanks for the heads-up about these test images.

Using GraphicsMagick with libtiff 3.9.5 as provided with Ubuntu 12.04, 
I do see a small number of files which elicit valgrind reports.  Some 
of these seem to be due activities in libtiff while others could be 
due to some weakness in GraphicsMagick.  The situation does not look 
terrible.

I will install latest CVS libtiff on this system and re-run 
GraphicsMagick under valgrind.

While it is desireable that the libtiff utilities be reasonably secure 
(especially those which are heavily used), the focus of most users is 
on the library itself.

Bob
