Also from Tiff Rev. 6.0:

3 = SHORT 16-bit (2-byte) unsigned integer
4 = LONG 32-bit (4-byte) unsigned integer

StripByteCounts
For each strip, the number of bytes in the strip after compression
Tag = 279 (117.H)
Type = SHORT or LONG
...

StripOffsets
For each strip, the byte offset of that strip
Tag = 279 (117.H)
Type = SHORT or LONG
...

This rather clearly sets the data offset pointers and counters as unsigned, and the limit as 4 GB.
