Subject: [PATCH] * libtiff/tif_dirread.c: modify
ChopUpSingleUncompressedStrip() to instanciate compute ntrips as
TIFFhowmany_32(td->td_imagelength, rowsperstrip), instead of a logic based on
the total size of data. Which is faulty is the total size of data is not
sufficient to fill the whole image, and thus results in reading outside of
the StripByCounts/StripOffsets arrays when using TIFFReadScanline(). Reported
by Agostino Sarubbo. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2608.
* libtiff/tif_strip.c: revert the change in TIFFNumberOfStrips() done
for http://bugzilla.maptools.org/show_bug.cgi?id=2587 / CVE-2016-9273 since
the above change is a better fix that makes it unnecessary.
