Please unblock package tiff
This is a very localized patch to the tiffcp utility (doesn't even
affect the tiff library) to fix a potential crash, fixing RC bug
#741451. The originated from upstream where it was based on a fix
previously submitted by the original reporter.
(include/attach the debdiff against the package in testing)

+Description: fix for Debian bug #741451
+ tiffcp crashes when converting JPEG-encoded TIFF to a different
+ encoding (like none or lzw). For example this will probably fail:
+ .
+ tiffcp -c none jpeg_encoded_file.tif output.tif
+ .
+ The reason is that when the input file contains JPEG data,
+ the tiffcp code forces conversion to RGB space. However,
+ the output normally inherits YCbCr subsampling parameters
+ from the input, which leads to a smaller working buffer
+ than necessary. The buffer is subsequently overrun inside
+ cpStripToTile() (called from writeBufferToContigTiles).
+ Note that the resulting TIFF file would be scrambled even
+ if tiffcp wouldn't crash, since the output file would contain
+ RGB data intepreted as subsampled YCbCr values.
+ .
+ This patch fixes the problem by forcing RGB space on the output
+ TIF if the input is JPEG-encoded and output is *not* JPEG-encoded.
