sgisv, and ycbcr are completely removed from the distribution.

These tools were written in the late 1980s and early 1990s for
|
|
Packit |
85355f |
test and demonstration purposes. In some cases the tools were
|
|
Packit |
85355f |
never updated to support updates to the file format, or the
|
|
Packit |
85355f |
file formats are now rarely used. In all cases these tools
|
|
Packit |
85355f |
increased the libtiff security and maintenance exposure beyond
|
|
Packit |
85355f |
the value offered by the tool.

that values of tags with TIFF_SETGET_C16_ASCII /

85355f |
that have no TileOffsets/StripOffsets tag, when OJPEG

libtiff/tif_dir.c: discard values of SMinSampleValue and

Packit |
85355f |
SMaxSampleValue when they have been read and the value of

Packit |
85355f |
SamplesPerPixel is changed afterwards (like when reading a

Packit |
85355f |
OJPEG compressed image with a missing SamplesPerPixel tag, and
|

Packit |
85355f |
whose photometric is RGB or YCbCr, forcing SamplesPerPixel
|
|
Packit |
85355f |
being 3). Otherwise when rewriting the directory (for example
|
|
Packit |
85355f |
with tiffset, we will expect 3 values whereas the array had
|

Packit |
85355f |

Packit |
85355f |
practice outside of the odd behaviour of t2p_seekproc() of

check the return value of TIFFFlushData1() in places where it
