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.

SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample
!= 8 * libtiff/tif_next.c: in the "run mode", use tilewidth for tiled images
instead of imagewidth to avoid crash * tools/bmp2tiff.c: fix crash due to int
overflow related to input BMP dimensions * tools/tiff2pdf.c: fix crash due to
invalid tile count (should likely be checked by libtiff too). Detect invalid
settings of BitsPerSample/SamplesPerPixel for CIELAB / ITULAB *
tools/tiffcrop.c: fix crash due to invalid TileWidth/TileHeight *
