Sorry, they are from the following imagetestsuite archive, not the above ZaaLabs one:
Images here are eccentric. Inspection by human eyeballs is not effective.
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.
