Subject: [PATCH] * tools/tiff2rgba.c: Fix integer overflow in size of
 allocated buffer, when -b mode is enabled, that could result in out-of-bounds
 write. Based initially on patch tiff-CVE-2016-3945.patch from
 libtiff-4.0.3-25.el7_2.src.rpm by Nikola Forro, with correction for invalid
 tests that rejected valid files.

CVE: CVE-2016-3945

 simpler check. (bugzilla #2544)
