+Patch copied from upstream CVS. 3rd-party Git reference:
+https://github.com/vadz/libtiff/commit/4d4fa0b68ae9ae038959ee4f69ebe288ec892f06
+
+2017-06-01 Even Rouault <even.rouault at spatialys.com>
+
+* libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
+and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
+codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
+to behave differently depending on whether the codec is enabled or not, and
+thus can avoid stack based buffer overflows in a number of TIFF utilities
+such as tiffsplit, tiffcmp, thumbnail, etc.
+Patch derived from 0063-Handle-properly-CODEC-specific-tags.patch
+(http://bugzilla.maptools.org/show_bug.cgi?id=2580) by Raphaël Hertzog.
