- Update from version 4.5.1 to 4.6.0
- Update of rootfile

- Changelog
4.6.0
Major changes warning
This version removes a big number of utilities that have suffered from lack of
maintenance over the years and were the source of various reported security
issues. See "Removed functionality" below for the list of removed utilities.
Starting with libtiff v4.6.0, the source code for most TIFF tools
(except tiffinfo, tiffdump, tiffcp and tiffset) was discontinued, due to the
lack of contributors able to address reported security issues. tiff2ps and
tiff2pdf source code has been moved in a unsupported category, no longer built
by default, but are still part of the the source distribution. Other retired
utilities are in a archive/ directory, only available in the libtiff git
repository. Issues related to unsupported and archived tools will no longer be
accepted in the libtiff bug tracker.
Software configuration changes
TiffConfig.cmake.in: set TIFF_INCLUDE_DIR, TIFF_INCLUDE_DIRS and
TIFF_LIBRARIES for compatibility with FindTIFF.cmake as shipped by CMake
(fixes issue #589)
Update CMake and autoconf scripts to consistently update LibTIFF version
defines and references in various files when version definition in
configure.ac has been changed.
Move in tiffvers.h from libtiff source directory to libtiff build
directory.
Remove unused version information from tif_config.h
With every CMake build the version defines (e.g. 4.5.1) within tiffvers.h
are consistently updated from configure.ac. The version release-date is
taken from file RELEASE-DATE.
The files VERSION and RELEASE-DATE are only updated with a special CMake
target build: cmake --build . --target tiff_release.
For autotools, version information is updated from configure.ac with
./autogen.sh. LIBTIFF_RELEASE_DATE is taken form file RELEASE-DATE.
./configure generates tiffvers.h with the cached version information and
LIBTIFF_RELEASE_DATE.
"make release" updates tiffvers.h and VERSION file with cached version
info and RELEASE-DATE file and tiffves.h with the current date.
CMake: fix build with -Dstrip-chopping=off (fixes issue #600)
Library changes
New/improved functionalities:
Fix using __attribute__ libtiff with clang-for-windows
Bug fixes:
WebP decoder: validate WebP blob width, height, band count against TIFF
parameters to avoid use of uninitialized variable, or decoding corrupted
content without explicit error (fixes issue #581, issue #582).
WebP codec: turn exact mode when creating lossless files to avoid altering
R,G,B values in areas where alpha=0
(https://github.com/OSGeo/gdal/issues/8038)
Fix TransferFunction writing of only two transfer functions.
TIFFReadDirectoryCheckOrder: avoid integer overflow. When it occurs, it
should be harmless in practice though
(https://gitlab.com/libtiff/libtiff/-/merge_requests/512)
Documentation
TiffField functions documentation updated with return behaviour for not
defined tags and determination of write-/read-count size.
Tools changes
Removed functionality:
The following tools are no longer compiled and have been moved to
archive/tools:
fax2ps
fax2tiff
pal2rgb
ppm2tiff
raw2tiff
rgb2ycbcr
thumbnail
tiff2bw
tiff2rgba
tiffcmp
tiffcrop
tiffdither
tiffgt
tiffmedian
The following tools are no longer compiled by default: tiff2ps and tiff2pdf.
They have been moved to tools/unsupported. They can be built by setting
--enable-tools-unsupported for autoconf, or -Dtiff-tools-unsupported for
CMake, but as the name imply, they are no longer supported by upstream.
Packagers are suggested not to enable those options.
tiffcp: remove -i option (ignore errors), because almost all fuzzer issues
were consequential errors from ignored errors because of the "-i" option.
Bug fixes:
tiffset: fix#597: warning: comparison of integer expressions of different
signedness. (fixes issue #597)
tiffcp: fix memory corruption (overflow) on hostile images (fixes issue #591)
Test changes
Add missing test_write_read_tags.c and test_transferfunction_write_read.c in
tarball (fixes issue #585) and correct "long" issue.
Don't use "long" because can be int32_t or int64_t, depending on compiler
and system.
Changes to contributed and unsupported tools
raw2tiff: fix integer overflow and bypass of the check (fixes issue #592)

libtiff, therefore this library has to become a part of the
core distribution too.
