libtiff6-4.6.0-150600.1.4 RPM for ppc64le

From OpenSuSE Leap 15.6 for ppc64le

Name: libtiff6 Distribution: SUSE Linux Enterprise 15
Version: 4.6.0 Vendor: SUSE LLC <>
Release: 150600.1.4 Build date: Thu May 9 18:14:45 2024
Group: System/Libraries Build host: xinomavro
Size: 728961 Source RPM: tiff-4.6.0-150600.1.4.src.rpm
Summary: The Tiff Library (with JPEG and compression support)
This package includes the tiff libraries. To link a program with
libtiff, you will have to add -ljpeg and -lz to include the necessary
libjpeg and libz in the linking process.






* Fri Sep 15 2023
  - Update to version 4.6.0:
    * API/ABI breaks: none
    * 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
    * Fix TransferFunction writing of only two transfer functions.
    * TIFFReadDirectoryCheckOrder: avoid integer overflow. When it occurs,
      it should be harmless in practice though
    * tiffcp: remove -i option (ignore errors)
    * 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:
      + fax2ps
      + fax2tiff
      + pal2rgb
      + ppm2tiff
      + raw2tiff
      + rgb2ycbcr
      + thumbnail
      + tiff2bw
      + tiff2rgba
      + tiffcmp
      + tiffcrop
      + tiffdither
      + tiffgt
      + tiffmedian
      + tiff2ps
      + tiff2pdf
  - Remove no longer needed tiff-4.0.3-compress-warning.patch.
* Tue Jun 20 2023
  - Update to version 4.5.1:
    * Definition of tags reformatted (clang-format off) for better readability of tag comments in tiff.h and tif_dirinfo.c
    * Do not install libtiff-4.pc when tiff-install is reset.
    * Add versioninfo resource files for DLL and tools compiled with Windows MSVC and MINGW.
    * Disable clang-formatting for and because sensitive for CMake scripts.
    * CMake: make WebP component name compatible with upstream ConfigWebP.cmake
    * CMake: make Findliblzma with upstream CMake config file
    * CMake: FindDeflate.cmake: fix several errors (issue #526).
    * CMake: FindLERC.cmake: version string return added.
    * CMake: export TiffConfig.cmake and TiffConfigVersion.cmake files
    * Hardcode HOST_FILLORDER to FILLORDER_LSB2MSB and make 'H' flag of TIFFOpen() to warn and an alias of FILLORDER_MSB2LSB. tif_lerc.c: use WORDS_BIGENDIAN instead of HOST_BIGENDIAN.
    * Optimize relative seeking within TIFFSetDirectory() by using the learned list of IFD offsets.
    * Improve internal IFD offset and directory number map handling.
    * Behavior of TIFFOpen() mode "r+" in the Windows implementation adjusted to that of Linux.
    * TIFFDirectory td_fieldsset type changed from unsigned long, which can be 32 or 64 bits, to uint32_t (fixes issue #484).
    * tif_ojpeg.c: checking for division by zero (fixes issue #554).
    * LZWDecode(): avoid crash when trying to read again from a strip whith a missing end-of-information marker (fixes issue #548).
    * Fixed runtime error: applying zero offset to null pointer in countInkNamesString().
    * Fixing crash in TIFFUnlinkDirectory() when called with directory number zero ("TIFFUnlinkDirectory(0)") as well as fixing incorrect behaviour when unlinking the first directory.
    * tif_luv: check and correct for NaN data in uv_encode() (issue #530).
    * TIFFClose() avoid NULL pointer dereferencing (issue #515).
    * tif_hash_set.c: include tif_hash_set.h after tif_config.h to let a chance for GDAL symbol renaming trick.
    * Fax3: fix failure to decode some fax3 number_of_images and add test for Fax3 decoding issues (issue #513).
    * TIFFSetDirectory() and TIFFWriteDirectorySec() avoid harmless unsigned-integer-overflow (due to gdal oss-fuzz #54311 and #54343).
    * tif_ojpeg.c: fix issue #554 by checking for division by zero in OJPEGWriteHeaderInfo().
    * LZWDecode(): avoid crash when trying to read again from a strip whith a missing end-of-information marker (issue #548).

      + tiff-CVE-2022-48281.patch
* Wed Jan 04 2023
  - Update to 4.5.0:
    * tdir_t type updated to uint32_t. This type is now used for the return
      value of TIFFCurrentDirectory() and TIFFNumberOfDirectories(), and as
      the argument of TIFFSetDirectory() and TIFFUnlinkDirectory()
    * Addition of an open option concept with the new functions TIFFOpenExt(),
      TIFFOpenWExt(), TIFFFdOpenExt(), TIFFClientOpenExt(), TIFFOpenOptionsAlloc(),
    * Leveraging above mentioned open option concept, addition of a new capability
      to limit the size of a single dynamic memory allocation done by the library
      with TIFFOpenOptionsSetMaxSingleMemAlloc()
    * Related to IFD-Loop detection refactoring, the number of IFDs that libtiff
      can browse through has been extended from 65535 to 1048576. This value is
      a build-time setting that can be configured with CMake's TIFF_MAX_DIR_COUNT
      variable or autoconf's --with-max-dir-count option.
    * Whole code base reformatting of .c/.h files using new .clang-format format
    * Documentation changed from static HTML and man pages to
      Restructured Text (rst). HTML and man pages are now build artifacts.
    * SONAME version bumped to 6 due to changes in symbol versioning.
    * autoconf/cmake: detect (not yet released) libjpeg-turbo 2.2 to take into
      its capability of handling both 8-bit JPEG and 12-bit JPEG in a single build.
    * autoconf/cmake: detect sphinx-build to build HTML and man pages
    * CMakeLists.txt: fix warning with -Wdev

    * CMake: Moved linking of CMath::CMath into CMath_LIBRARY check.
    * Fix CMake build to be compatible with FetchContent.
    * cmake: Correct duplicate definition of _CRT_SECURE_NO_WARNINGS
    * cmake: Fixes for Visual Studio 2022.
    * Adds Requires.private generation so that pkg-config can correctly find
      the dependencies of libtiff.
    * Fix dependency on libm on Android
    * Fix build in tif_lzw.c
    * CMake: Add options for disabling tools, tests, contrib and docs.
    * tiffcrop: Fix memory allocation to require a larger buffer (CVE-2022-3570, CVE-2022-3598)
    * tiffcrop: disable incompatibility of -Z, -X, -Y, -z options with any PAGE_MODE_x option
      (CVE-2022-3627, CVE-2022-3597, CVE-2022-3626)
    * tiffcrop: fix floating-point exception (CVE-2022-2056, CVE-2022-2057, CVE-2022-2058)
    * _TIFFCheckFieldIsValidForCodec(): return FALSE when passed a codec-specific tag
      and the codec is not configured (CVE-2022-34526)
    * Revised handling of TIFFTAG_INKNAMES and related TIFFTAG_NUMBEROFINKS value (CVE-2022-3599)
    * tiffcrop: -S option mutually exclusive (CVE-2022-2519, CVE-2022-2520, CVE-2022-2521)

      by Roger Leigh. This patch adds support for the Travis-CI
      + .appveyor.yml: new file from
      0002-ci-Add-AppVeyor-support.patch by Roger Leigh (sent to
      mailing list on 2017-06-08) This patch adds a .appveyor.yml
      file to the top-level. This allows one to opt in to having a
      branch built on Windows with Cygwin, MinGW and MSVC
      automatically when a branch is pushed to GitHub, GitLab,
      BitBucket or any other supported git hosting service.
      + CMakeLists.txt, test/CMakeLists.txt,
      test/TiffTestCommon.cmake: apply patch
      0001-cmake-Improve-Cygwin-and-MingGW-test-support.patch from
      Roger Leigh. This patch makes the CMake build system support
      running the tests with MinGW or  Cygwin.

      + nmake.opt: support a DEBUG=1 option, so as to adjust OPTFLAGS
      and use /MDd runtime in debug mode.
    * Changes in libtiff:
      + libtiff/tif_color.c: TIFFYCbCrToRGBInit(): stricter clamping
      to avoid int32 overflow in TIFFYCbCrtoRGB(). Fixes
      + libtiff/tif_getimage.c: initYCbCrConversion(): stricter
      validation for refBlackWhite coefficients values. To avoid
      invalid float->int32 conversion (when refBlackWhite[0] ==
      2147483648.f) Fixes
      + libtiff/tif_dirinfo.c, tif_dirread.c: add
      _TIFFCheckFieldIsValidForCodec(), and use it in
      TIFFReadDirectory() so as to ignore fields whose tag is a
      codec-specified tag but this codec is not enabled. This avoids
      TIFFGetField() to behave differently depending on whether the
      codec is enabled or not, and thus can avoid stack based buffer
      overflows in a number of TIFF utilities such as tiffsplit,
      tiffcmp, thumbnail, etc. Patch derived from
      ( by Raphaƫl
      (CVE-2016-10095, bsc#1017690)
      (CVE-2015-7554, bsc#960341)
      (CVE-2016-5318, bsc#983436)
      (CVE-2014-8128, bsc#969783)
      + libtiff/tif_swab.c: if DISABLE_CHECK_TIFFSWABMACROS is
      defined, do not do the #ifdef TIFFSwabXXX checks. Make it
      easier for GDAL to rename the symbols of its internal libtiff
      + libtiff/tif_dirread.c: fix regression of libtiff 4.0.8 in
      ChopUpSingleUncompressedStrip() regarding update of newly
      single-strip uncompressed files whose bytecount is 0. Before
      the change of 2016-12-03, the condition bytecount==0 used to
      trigger an early exit/disabling of strip chop. Re-introduce
      that in update mode. Otherwise this cause later incorrect
      setting for the value of StripByCounts/StripOffsets.
      + libtiff/tif_dirread.c: TIFFFetchStripThing(): limit the
      number of items read in StripOffsets/StripByteCounts tags to
      the number of strips to avoid excessive memory allocation.
      + libtiff/tif_getimage.c: avoid many (harmless) unsigned int
      + libtiff/tif_fax3.c: avoid unsigned int overflow in
      Fax3Encode2DRow(). Could potentially be a bug with huge rows.
      + libtiff/tif_jpeg.c: avoid (harmless) unsigned int overflow on
      tiled images.
      + libtiff/tif_dirread.c: avoid unsigned int overflow in
      EstimateStripByteCounts() and BYTECOUNTLOOKSBAD when file is
      too short.
      + libtiff/tif_predict.c: decorate legitimate functions where
      unsigned int overflow occur with
      + libtiff/tif_dirread.c: avoid unsigned int overflow in
      + libtiff/tiffiop.h: add TIFF_NOSANITIZE_UNSIGNED_INT_OVERFLOW
      macro to disable CLang warnings raised by
    - fsanitize=undefined,unsigned-integer-overflow
      + libtiff/tif_jpeg.c: add anti-denial of service measure to
      avoid excessive CPU consumption on progressive JPEGs with a
      huge number of scans. See
      Note: only affects libtiff since 2014-12-29 where support of
      non-baseline JPEG was added.
      + libtiff/tif_jpeg.c: error out at decoding time if anticipated
      libjpeg memory allocation is above 100 MB. libjpeg in case of
      multiple scans, which is allowed even in baseline JPEG, if
      components are spread over several scans and not
      interleavedin a single one, needs to allocate memory (or
      backing store) for the whole strip/tile. See
      This limitation may be overriden by setting the
      LIBTIFF_ALLOW_LARGE_LIBJPEG_MEM_ALLOC environment variable, or
      recompiling libtiff with a custom value of
      + libtiff/tif_jbig.c: fix memory leak in error code path of
      (CVE-2017-9936, bsc#1046073)
      + libtiff/tif_dirread.c: in TIFFReadDirEntryFloat(), check that
      a double value can fit in a float before casting.
      + libtiff/tiffiop.h, libtiff/tif_jpeg.c, libtiff/tif_jpeg_12.c,
      libtiff/tif_read.c: make TIFFReadScanline() works in
      CHUNKY_STRIP_READ_SUPPORT mode with JPEG stream with multiple
      scans. Also make configurable through a
      LIBTIFF_JPEG_MAX_ALLOWED_SCAN_NUMBER environment variable the
      maximum number of scans allowed. Defaults to 100.
      + libtiff/tif_read.c: TIFFFillTile(): add limitation to the
      number of bytes read in case td_stripbytecount[strip] is
      bigger than reasonable, so as to avoid excessive memory
      allocation (similarly to what was done for TIFFFileStrip() on
      + libtiff/tif_getimage.c: use
      _TIFFReadEncodedStripAndAllocBuffer(). Fixes and
      + libtiff/tif_read.c, tiffiop.h: add a
      _TIFFReadEncodedStripAndAllocBuffer() function, variant of
      TIFFReadEncodedStrip() that allocates the decoded buffer only
      after a first successful TIFFFillStrip(). This avoids
      excessive memory allocation on corrupted files.
      + libtiff/tif_dirwrite.c: in TIFFWriteDirectoryTagCheckedXXXX()
      functions associated with LONG8/SLONG8 data type, replace
      assertion that the file is BigTIFF, by a non-fatal error.
      + libtiff/tif_read.c: TIFFStartTile(): set tif_rawcc to
      tif_rawdataloaded when it is set. Similarly to
      TIFFStartStrip(). This issue was revealed by the change of
      2017-06-30 in TIFFFileTile(), limiting the number of bytes
      read. But it could probably have been hit too in
      CHUNKY_STRIP_READ_SUPPORT mode previously. Fixes
      + libtiff/tif_error.c, tif_warning.c: correctly use va_list
      when both an old-style and new-style warning/error handlers
      are installed. Patch by Paavo Helde (sent on the mailing list)
      + libtiff/tif_getimage.c: use _TIFFReadTileAndAllocBuffer().
      + libtiff/tif_read.c, tiffiop.h: add a
      _TIFFReadEncodedTileAndAllocBuffer() and
      _TIFFReadTileAndAllocBuffer() variants of
      TIFFReadEncodedTile() and TIFFReadTile() that allocates the
      decoded buffer only after a first successful TIFFFillTile().
      This avoids excessive memory allocation on corrupted files.
      + libtiff/tif_pixarlog.c: avoid excessive memory allocation on
      decoding when RowsPerStrip tag is not defined (and thus
      td_rowsperstrip == UINT_MAX) Fixes
      + libtiff/tif_lzw.c: fix 4.0.8 regression in the decoding of
      old-style LZW compressed files.
      + libtiff/tif_lzw.c: fix potential out-of-buffer read on 1-byte
      LZW strips. Crashing issue only on memory mapped files, where
      the strip offset is the last byte of the file, and the file
      size is a multiple of one page size on the CPU architecture
      (typically 4096)
      + libtiff/tif_dir.c: avoid potential null pointer dereference
      in _TIFFVGetField() on corrupted TIFFTAG_NUMBEROFINKS tag
      + tools/tiff2pdf.c: prevent heap buffer overflow write in "Raw"
      mode on PlanarConfig=Contig input images. Fixes
      + libtiff/tif_read.c: TIFFFillStrip() / TIFFFillTile().
      Complementary fix for in the
      isMapped() case, so as to avoid excessive memory allocation
      when we need a temporary buffer but the file is truncated.
      + libtiff/tif_read.c: in TIFFFetchStripThing(), only grow the
      arrays that hold StripOffsets/StripByteCounts, when they are
      smaller than the expected number of striles, up to 1 million
      striles, and error out beyond. Can be tweaked by setting the
      environment variable LIBTIFF_STRILE_ARRAY_MAX_RESIZE_COUNT.
      This partially goes against a change added on 2002-12-17 to
      accept those arrays of wrong sizes, but is needed to avoid
      denial of services. Fixes
      + libtiff/tif_read.c: add protection against excessive memory
      allocation attempts in TIFFReadDirEntryArray() on short files.
      Effective for mmap'ed case. And non-mmap'ed case, but
      restricted to 64bit builds. Fixes
      (CVE-2017-12944, bsc#1054594)
      + libtiff/tif_luv.c: LogLuvInitState(): avoid excessive memory
      allocation when RowsPerStrip tag is missing. Fixes
      + libtiff/tif_getimage.c: gtTileContig() and gtTileSeparate():
      properly break from loops on error when stoponerr is set,
      instead of going on iterating on row based loop.
      + libtiff/tif_getimage.c: fix fromskew computation when
      to-be-skipped pixel number is not a multiple of the horizontal
      subsampling, and also in some other cases. Impact
      putcontig8bitYCbCr44tile, putcontig8bitYCbCr42tile,
      putcontig8bitYCbCr41tile, putcontig8bitYCbCr21tile and
      putcontig8bitYCbCr12tile Fixes and
      + libtiff/tif_luv.c: further reduce memory requirements for
      temporary buffer when RowsPerStrip >= image_length in
      LogLuvInitState() and LogL16InitState(). Fixes
      + libtiff/tif_dirwrite.c: replace assertion related to not
      finding the SubIFD tag by runtime check (in
      TIFFWriteDirectorySec()) Fixes
      + libtiff/tif_dirwrite.c: replace assertion to tag value not
      fitting on uint32 when selecting the value of SubIFD tag by
      runtime check (in TIFFWriteDirectoryTagSubifd()). Fixes
      + libtiff/tif_jpeg.c: accept reading the last strip of a JPEG
      compressed file if the codestream height is larger than the
      truncated height of the strip. Emit a warning in this
      situation since this is non compliant.
      + libtiff/tiffiop.h, tif_aux.c: redirect SeekOK() macro to a
      _TIFFSeekoK() function that checks if the offset is not
      bigger than INT64_MAX, so as to avoid a -1 error return code
      of TIFFSeekFile() to match a required seek to UINT64_MAX/-1.
      + libtiff/tif_dirread.c: add NULL check to avoid likely false
      positive null-pointer dereference warning by CLang Static
      + libtiff/libtiff.def: add TIFFReadRGBAStripExt and
      TIFFReadRGBATileExt Fixes
      + libtiff/tif_jpeg.c: add compatibility with libjpeg-turbo
      1.5.2 that honours max_memory_to_use > 0. Cf
      + libtiff/tif_getimage.c: avoid floating point division by zero
      in initCIELabConversion() Fixes
    * Changes in the tools:
      + tools/tiff2pdf.c: prevent heap buffer overflow write in "Raw"
      mode on PlanarConfig=Contig input images. Fixes
      + tools/tiffset.c: fix setting a single value for the
      ExtraSamples tag (and other tags with variable number of
      values). So 'tiffset -s ExtraSamples 1 X'. This only worked
      when setting 2 or more values, but not just one.
      + tools/fax2tiff.c (_FAX_Client_Data): Pass FAX_Client_Data as
      the client data. This client data is not used at all at the
      moment, but it makes the most sense. Issue that the value of
      client_data.fd was passed where a pointer is expected.
      + tools/tiff2pdf.c (t2p_sample_realize_palette): Fix possible
      arithmetic overflow in bounds checking code and eliminate
      comparison between signed and unsigned type.
      + tools/tiff2bw.c (main): Free memory allocated in the tiff2bw
      program. This is in response to the report associated with
      CVE-2017-16232, bsc#1069213 but does not solve the extremely
      high memory usage with the associated POC file.
* Tue Jun 20 2017
  - Upgrade to upstream release 4.0.8
    * libtiff/tif_getimage.c, libtiff/tif_open.c
      + add parenthesis to fix cppcheck clarifyCalculation warnings
    * libtiff/tif_predict.c, libtiff/tif_print.c
      + fix printf unsigned vs signed formatting (cppcheck
      invalidPrintfArgType_uint warnings)
    * libtiff/tif_read.c, libtiff/tiffiop.h
      + fix uint32 overflow in TIFFReadEncodedStrip() that caused an
      integer division by zero. Reported by Agostino Sarubbo.
    * libtiff/tif_pixarlog.c, libtiff/tif_luv.c
      + fix heap-based buffer overflow on generation of PixarLog / LUV
      compressed files, with ColorMap, TransferFunction attached and
      nasty plays with bitspersample. The fix for LUV has not been
      tested, but suffers from the same kind of issue of PixarLog.
      Reported by Agostino Sarubbo.
    * libtiff/tif_strip.c
      + revert the change in TIFFNumberOfStrips() done for /
      CVE-2016-9273 since the above change is a better fix that
      makes it unnecessary.
    * libtiff/tif_dirread.c
      + modify ChopUpSingleUncompressedStrip() to instanciate compute
      ntrips as TIFFhowmany_32(td->td_imagelength, rowsperstrip),
      instead of a logic based on the total size of data. Which is
      faulty is the total size of data is not sufficient to fill the
      whole image, and thus results in reading outside of the
      StripByCounts/StripOffsets arrays when using
      TIFFReadScanline(). Reported by Agostino Sarubbo.
    * libtiff/tif_ojpeg.c
      + make OJPEGDecode() early exit in case of failure in
      OJPEGPreDecode(). This will avoid a divide by zero, and
      potential other issues. Reported by Agostino Sarubbo.
    * libtiff/tif_write.c
      + fix misleading indentation as warned by GCC.
    * libtiff/tif_fax3.h
      + revert change done on 2016-01-09 that made Param member of
      TIFFFaxTabEnt structure a uint16 to reduce size of the
      binary. It happens that the Hylafax software uses the tables
      that follow this typedef (TIFFFaxMainTable, TIFFFaxWhiteTable,
      TIFFFaxBlackTable), although they are not in a public libtiff
      header. Raised by Lee Howard.
    * libtiff/tiffio.h, libtiff/tif_getimage.c
      + add TIFFReadRGBAStripExt() and TIFFReadRGBATileExt() variants
      of the functions without ext, with an extra argument to control
      the stop_on_error behaviour.
    * libtiff/tif_getimage.c
      + fix potential memory leaks in error code path of
    * libtiff/tif_jpeg.c
      + increase libjpeg max memory usable to 10 MB instead of libjpeg
      1MB default. This helps when creating files with "big" tile,
      without using libjpeg temporary files.

      bsc#1038438, CVE-2016-10371
    * libtiff/tif_dirread.c

      TIFFReadDirEntryCheckedRational() and
      TIFFReadDirEntryCheckedSrational(), and return 0 in that case
      (instead of infinity as before presumably) Apparently some
      sanitizers do not like those divisions by zero.
      bsc#1033118, CVE-2017-7598
    * libtiff/tif_dir.c, tif_dirread.c, tif_dirwrite.c
      + implement various clampings of double to other data types to
      avoid undefined behaviour if the output range isn't big enough
      to hold the input value.

      Idea based on libtiff-CVE-2016-3990.patch from

      check. (,
    * libtiff/tif_predict.c
      + PredictorSetup: Enforce bits-per-sample requirements of
      floating point predictor (3). Fixes CVE-2016-3622 "Divide By
      Zero in the tiff2rgba tool." (bsc#974449)
    * libtiff/tif_predict.h, libtiff/tif_predict.c

      when dealing with unusual tile size like YCbCr with
      subsampling. Reported as MSVR 35105.
    * libtiff/tif_read.c

    * libtiff/tif_strip.c
      + Make TIFFNumberOfStrips() return the td->td_nstrips value when
      it is non-zero, instead of recomputing it. This is needed in
      TIFF_STRIPCHOP mode where td_nstrips is modified. Fixes a read
      outsize of array in tiffsplit (or other utilities using
      TIFFNumberOfStrips()). Fixes

    * libtiff/tif_write.c
      + Fix issue in error code path of TIFFFlushData1() that didn't
      reset the tif_rawcc and tif_rawcp members. I'm not completely
      sure if that could happen in practice outside of the odd
      behaviour of t2p_seekproc() of tiff2pdf). The report points
      that a better fix could be to check the return value of
      TIFFFlushData1() in places where it isn't done currently, but
      it seems this patch is enough. Reported as MSVR 35095.

      directly use user provided buffer when no compression to save
      a memcpy().

    * tiff-4.0.6-CVE-2015-7554.patch
    - fix CVE-2015-7554: Out-of-bounds Write in the thumbnail and
      tiffcmp tools (upsteam bug #2499) [bsc#960341]
* Mon Jan 11 2016
  - Added patch:
    * tiff-4.0.4-uninitialized_mem_NeXTDecode.patch
    - fix uninitialized memory in NeXTDecode (upstream bug #2508)
* Tue Dec 08 2015
  - Update to version 4.0.6
    * Supports CMake 2.8.9 and later.
    * Add missing file which wasn't being distributed, causing unit
      tests to fail.
    * Make shared/static library building configurable.
    * CMake reads all version information directly from
      to avoid duplication of values.
    * CMake builds are now included in 'distcheck' target.
    * Autotools 'make distcheck' now tests the CMake-based build if
      CMake is available.
    * Fixes to avoid undefined behaviour of signed types (C standard
    * Fixes to avoid possible isses when casting to unsigned char.
    * Fixes to avoid undefined behaviour with shifts.
    * Fix generation of output with 16 bit or 32 bit integer, when
      byte swapping is needed, in horizontal predictor (#2521).
    * Fix decoding when there is a single pixel to decode
      (unlikely case...) and byte swapping is involved.
    * Add add explicit masking with 0xff before casting to uchar in
      floating-point horizontal differencing and accumulation routines.
    * Eliminate requirement for and use of 64-bit constant values.
    * tiffgt : Silence glut API deprecation warnings on MacOS X.
    * fax2ps : Detect failure to write to temporary file.
  - Changes from version 4.0.5
    * Support for configure/build using CMake.
    * Support for large (> 2GB) files under Microsoft Windows.
    * Configuration and building using CMake is now supported under
      Microsoft Windows and on Unix-type systems.
    * Test for and use fseeko() if it is available. This allows supporting
      large files on Unix-type systems with a 32-bit 'long' type and a
      64-bit 'off_t' type.
    * tiffiop.h: Macros added to use 64-bit equivalents for all standard
      I/O and POSIX APIs used by libtiff and its tools which are limited
      to 2GB in Windows builds. Note that these 64-bit equivalents were
      introduced by the CRT provided with Visual Studio 2005 and if the
      necessary CRT is not installed on the target computer, the program
      will not run. The wrapper macros will not be activated unless the
      definition _MSC_VER is at least 1400 or __MSVCRT_VERSION__ is at
      least 0x800.
    * tif_unix.c: Updated to support large files under Microsoft Windows.
      This makes tif_unix.c a completely viable candidate for use under
      Windows (in spite of its name) if the CRT is modern enough. Please
      note that tif_win32.c already supported large files, but only
      'tiffinfo' and 'tiffdump' made any provision to support large files
      under Windows.
    * _tiffReadProc() and _tiffWriteProc() are modified to chunk I/O to a
      maximum size of 2GB for extremely large I/O requests. This surmounts
      limitations in the Microsoft Windows read() and write() APIs (which
      are limited to the range of a 32-bit 'int'), and may avoid poor
      behavior with extremely large I/O requests on other systems.
    * Updated to use I/O wrapper macros from tiffiop.h in order to
      support large files under Microsoft Windows.
