+
+The patch (https://codereview.chromium.org/2284063002) for Issue 618267

+[libtiff] Validate refblackwhite values
+
+The td_refblackwhite value is currently assigned without validation. This
+may pose an issue as the image can specify the value as nan. This will cause
+problems later when we use the nan in calcluations.
+
+This CL validates each of the float values are not nan and if they are sets
+them to the default provided by the TIFF spec v6.
