It is possible to craft a TIFF document where the IFD list is circular,
leading to an infinite loop while traversing the chain. The libtiff
directory reader has a failsafe that will break out of this loop after
reading 65535 directory entries, but it will continue processing,
consuming time and resources to process what is essentially a bogus TIFF
document.
This change fixes the above behavior by breaking out of processing when
a TIFF document has >= 65535 directories and terminating with an error.

with BSD make and to make use of cmake in 'distcheck' target

libtiff mailing list on Mon, 22 Jun 2015 21:21:01 +0100. Several
corrections to ensure that the autotools build still works were
added by me. I have not yet tested the build using 'cmake' or
MSVC with 'nmake'.
some TIFF/FX support in libtiff. Add the tag definitions to
tiff.h. Add the related TIFF field definitions to tif_dirinfo.c,
and also fixes an error in a comment. Adds the photometric values
to tif_print.c, and fixes a bug. These changes are by Steve
Underwood.
* libtiff/tif_write.c: Fix bug rewriting image tiles in a
the run-time target whereas target is used to specify the final
output target if the package is a build tool (like a compiler),
which libtiff is not. Resolves libtiff bug 2307 "Use
AC_CANONICAL_HOST macro".
* libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of
buffer due to integer overflow in TIFFroundup() and several other
potential overflows. In conjunction with the fix to TIFFhowmany(),
fixes CVE-2010-1411.
* libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
result in an integer overflow. This causes TIFFroundup() to also
return zero if there would be an integer overflow.
libtool 2.2.6. Enabled support for silent build rules
(--enable-silent-rules or 'make V=0') and colorized tests.
* html/{index.html, v3.9.0.html}: Update for 3.9.0 release.

* configure.ac: Add configure support for determining sized types
in a portable way and performing necessary substitutions in
tif_config.h and tiffconf.h. Updated tiff.h to use the new
definitions.
