Fix heap buffer overflow in tiffcp when parsing number of inks:
http://bugzilla.maptools.org/show_bug.cgi?id=2599
2016-12-03 Even Rouault <even.rouault at spatialys.com>
* tools/tif_dir.c: when TIFFGetField(, TIFFTAG_NUMBEROFINKS, ) is
called,
limit the return number of inks to SamplesPerPixel, so that code that
parses
ink names doesn't go past the end of the buffer.
Reported by Agostino Sarubbo.
