This document provides a summary of significant changes made to the
software between the previous and current versions (see
above). A fully-detailed change summary is provided by the ChangeLog file
included in the release package and by the Git commit history:
Major changes¶
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.
Software configuration changes¶
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: correctly set default value of 'lzma' option when liblzma is detected (issue #482)
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 (issue #443)
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
cmake: libtiffxx is static on win32
Fix build in tif_lzw.c
CMake: Add options for disabling tools, tests, contrib and docs.
Library changes¶
New/improved functionalities:
Addition of an open option concept with the new functions
TIFFOpenExt(),TIFFOpenWExt(),TIFFFdOpenExt(),TIFFClientOpenExt(),TIFFOpenOptionsAlloc(),TIFFOpenOptionsFree()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()Leveraging above mentioned open option concept, addition of a new capability to specify per-TIFF handle re-entrant error and warning callbacks with
TIFFOpenOptionsSetErrorHandlerExtR()andTIFFOpenOptionsSetWarningHandlerExtR()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.
API/ABI breaks:
tdir_t type updated to uint32_t. This type is now used for the return value of
TIFFCurrentDirectory()andTIFFNumberOfDirectories(), and as the argument ofTIFFSetDirectory()andTIFFUnlinkDirectory()
Bug fixes:
TIFFWriteRawStrip(): restore capabilities to append data in the current strip (issue #489)
_TIFFReadEncodedTileAndAllocBuffer(): avoid excessive memory allocation on broken files (issue #479)
TIFFReadRGBATileExt(): fix (unsigned) integer overflow on strips/tiles > 2 GB (oss-fuzz #53137)
Replace sprintf calls with snprintf to fix warnings on macOS 13 SDK
Added warning messages for FIELD_IGNORE tags for writing and for TIFF_SETGET_UNDEFINED for reading added. (issue #438)
tif_dirinfo.c: fix TIFFTAG_CLIPPATH tag declaration (issue #439)
tif_dirinfo.c: fix TIFFTAG_COMPRESSION and _BITSPERSAMPLE tag declaration (issue #364)
Revised handling of TIFFTAG_INKNAMES and related TIFFTAG_NUMBEROFINKS value (issue #149, issue #150, issue #152, issue #168, issue #250, issue #269,:issue:398, CVE-2022-3599, issue #456)
TIFFAdvanceDirectory(): fix unsigned-integer-overflow in mapped case (oss-fuzz #52309)
Improved/fixes IFD-Loop Handling (issue #455).
Update getimage to support large raster images.
Presetting of default tag values extended (e.g. PlanarConfig). (issue #449)
Deal with RichTIFFIPTC tag written with LONG type (issue #225)
TIFFSetValue(): Writing IFD8 & LONG8 tags to ClassicTIFF corrected (issue #442)
tif_jpeg.c: allow to pass -DEXPECTED_JPEG_LIB_VERSION=number to do optional compile-time version check
TIFFReadFromUserBuffer(): fix clearing of TIFF_CODERSETUP flag that could cause issues with reading JPEG compressed files
_TIFFCheckFieldIsValidForCodec(): return FALSE when passed a codec-specific tag and the codec is not configured (issue #433, issue #486, CVE-2022-34526)
Add basic 16 bit cielab support.
WEBP codec: avoid temporary buffer and memcpy() on whole tile/strip decoding
tif_predict.c: make horAcc8() work with icc (ICC) 2021.6.0 20220226 -O2
Tools changes¶
New/improved functionality:
tiffinfo: Updated to parse through SubIFDs and show their tags.
Bug fixes:
tiffcrop: add check if (bps != 1) in writeSingleSection() (issue #169)
tiffcrop: Fix too many 'mode' options on command line (issue #470 and issue #450)
tiffcrop: Fix memory allocation to require a larger buffer (issue #271, issue #381, issue #386, issue #388, issue #389, issue #435, CVE-2022-3570, CVE-2022-3598)
tiffcrop: disable incompatibility of -Z, -X, -Y, -z options with any PAGE_MODE_x option (issue #411, CVE-2022-3627, issue #413, CVE-2022-3597, issue #426, CVE-2022-3626)
tiffcrop: -S option mutually exclusive (issue #349, issue #414, issue #422, issue #423, issue #424)
