Upstream says C99 is required (during a discussion about README not
specifying prereqs).
|

Upstream does not provide NEWS. Skimming over 1300 lines of
ChangeLog, this release contains mostly bufixes, speed improvemnents,
and other minor improvements.
This commit drops 5 patches for CVEs. These patches all appear to
have been taken from the upstream repo.
One CVE remains:

MAJOR CHANGES:
Optional support for using libdeflate is added.
Many of the tools now support a memory usage limit.
CHANGES IN LIBTIFF:
A great many issues discovered by fuzzers (via oss-fuzz and other reports) have been addressed.
EXIF 2.32 and GPS tags and functionality have been upgraded:
Existing EXIF field definition of tags are upgraded to EXIF version 2.3.2
EXIF-GPS structure, tags and access functions are added as special CustomDirectory (like it was done for EXIF).
Reading error for FileSource and SceneType tags corrected.
Make TIFFTAG_CFAPATTERN variable count.
Cmake configuration fixes for big-endian targets.
Added support for optional building against libdeflate for faster Zip/Deflate compression/decompression.
We now have 2 kinds of builds with the Zip/Deflate codec:
zlib only
zlib + libdeflate
Speed improvements in the 35%-50% range can be expected when libdeflate is used. Compression level up to 12 is now supported (capped to 9 when zlib is used). Still requires zlib for situations where libdeflate cannot be used (that is for scanline access, since libdeflate has no streaming mode)
Pseudo-tag TIFFTAG_DEFLATE_SUBCODEC=DEFLATE_SUBCODEC_ZLIB/DEFLATE_SUBCODEC_LIBDEFLATE is added to control which subcodec (zlib or libdeflate) should be used (it defaults of course to libdeflate, when it is available). This is mostly aimed at being used on the writing side, to be able to reproduce output of previous libtiff versions at a binary level, in situations where this would be really needed. Or as a safety belt in case there would be unforeseen issues with using libdeflate. It can be used to know when libdeflate is available at runtime (DEFLATE_SUBCODEC_LIBDEFLATE will be the default value in that situation).
Of course, deflate codestreams produced by libdeflate can be read by zlib, and vice-versa.
CHANGES IN THE TOOLS:
A great many issues discovered by fuzzers (via oss-fuzz and other reports) have been addressed.
ppm2tiff: support any bps value from 1 to 16.
tiff2ps, tiff2rgba: A default memory limit is now enforced (256MiB) and a '-M' option is added to allow the user to adjust the limit.
tiff2pdf, tiffcp: A default memory limit is now enforced (256MiB) and a '-m' option is added to allow the user to adjust the limit.
tiffcrop: A default memory limit is now enforced (256MiB) and a '-k' option is added to allow the user to adjust the limit.
tiff2pdf: fix "raw" copy of Deflate streams.
tiff2pdf.c: properly calculate datasize when saving to JPEG YCbCr
tiffcp: disable strip chopping when trying to convert to JBIG compression
|

We don't want it to randomly pick up system libwebp on Linux.
If there is a use case for webp compression here it should use the
pkgsrc library.

Upstream changes are basically minor improvements and bugfixes.
Specifically upstream states that there are no ABI changes.
Multiple security bugs are fixed due to fuzzing; patches are dropped
because they were backported from upstream.

Bump PKGREVISION.
|

It has been a year since the previous release. This is the first
release made from the Git repository at
https://gitlab.com/libtiff/libtiff using a collaborative process.
Since the previous release, a number of security issues have been
fixed, and some significant new features have been added.
This release adds support for Zstd and WebP compression algorithms.
In their own way, each of these compression algorithms is highly
complimentary to TIFF.
Zstd provides improved compression and decompression speed vs zlib's
Deflate as well as a broader range of compression ratios. Zstd is
developed by Facebook and the implementation continues to be improved.
WebP is optimized for small/medium 8-bit images while offering
improved compression performance vs traditional JPEG. WebP works well
in strips or tiles to compress large images down to very small files,
while preserving a good looking image. WebP is developed by Google,
and its implementation continues to be improved.
Due to Adobe's TIFF tag registration interface going off-line, we have
had to assign our own tags for Zstd and WebP.

Subject: [PATCH 1/1] JBIG: fix potential out-of-bounds write in JBIGDecode()
JBIGDecode doesn't check if the user provided buffer is large enough
to store the JBIG decoded image, which can potentially cause out-of-bounds
write in the buffer.
This issue was reported and analyzed by Thomas Dullien.
Also fixes a (harmless) potential use of uninitialized memory when
tif->tif_rawsize > tif->tif_rawcc
And in case libtiff is compiled with CHUNKY_STRIP_READ_SUPPORT, make sure
that whole strip data is provided to JBIGDecode()
The last part (CHUNKY_STRIP_READ_SUPPORT) was adapted by myself to fit
the libtiff release.

Pkgsrc changes:
* Adapt PLIST, remove patches for now-integrated bugfixes.
As the release announcement says:
All of the changes are bug and security fixes.
Upstream changes:
CHANGES IN LIBTIFF:
* 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. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2596
* 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. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2604
* libtiff/tif_strip.c: revert the change in TIFFNumberOfStrips()
done for http://bugzilla.maptools.org/show_bug.cgi?id=2587 /
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. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2608.
* 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. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2611
* 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. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2636
* 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 TIFFRGBAImageBegin(). Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2627
* 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. Related
to https://trac.osgeo.org/gdal/ticket/6757
* libtiff/tif_jpeg.c: avoid integer division by zero in
JPEGSetupEncode() when horizontal or vertical sampling is set
to 0. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2653
* libtiff/tif_dirwrite.c: in TIFFWriteDirectoryTagCheckedRational,
replace assertion by runtime check to error out if passed value
is strictly negative. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2535
* libtiff/tif_dirread.c: avoid division by floating point 0 in
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. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2644
* 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. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2643
http://bugzilla.maptools.org/show_bug.cgi?id=2642
http://bugzilla.maptools.org/show_bug.cgi?id=2646
http://bugzilla.maptools.org/show_bug.cgi?id=2647
* libtiff/tif_jpeg.c: validate BitsPerSample in JPEGSetupEncode()
to avoid undefined behaviour caused by invalid shift exponent.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2648
* libtiff/tif_read.c: avoid potential undefined behaviour on signed
integer addition in TIFFReadRawStrip1() in isMapped() case.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2650
* libtiff/tif_getimage.c: add explicit uint32 cast in putagreytile
to avoid UndefinedBehaviorSanitizer warning. Patch by Nicolás
Peña. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2658
* libtiff/tif_read.c: TIFFReadBufferSetup(): use _TIFFcalloc() to
zero initialize tif_rawdata. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2651
* libtiff/tiffio.h, tif_unix.c, tif_win32.c, tif_vms.c: add _TIFFcalloc()
* libtiff/tif_luv.c, tif_lzw.c, tif_packbits.c: return 0 in Encode
functions instead of -1 when TIFFFlushData1() fails. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2130
* libtiff/tif_ojpeg.c: fix leak in OJPEGReadHeaderInfoSecTablesQTable,
OJPEGReadHeaderInfoSecTablesDcTable and
OJPEGReadHeaderInfoSecTablesAcTable when read fails. Patch by
Nicolás Peña. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2659
* libtiff/tif_jpeg.c: only run JPEGFixupTagsSubsampling() if the
YCbCrSubsampling tag is not explicitly present. This helps a
bit to reduce the I/O amount when the tag is present (especially
on cloud hosted files).
* libtiff/tif_lzw.c: in LZWPostEncode(), increase, if necessary,
the code bit-width after flushing the remaining code and before
emitting the EOI code. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=1982
* libtiff/tif_pixarlog.c: fix memory leak in error code path of
PixarLogSetupDecode(). Patch by Nicolás Peña. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2665
* libtiff/tif_fax3.c, tif_predict.c, tif_getimage.c: fix GCC 7
-Wimplicit-fallthrough warnings.
* libtiff/tif_dirread.c: fix memory leak in non DEFER_STRILE_LOAD
mode (ie default) when there is both a StripOffsets and TileOffsets
tag, or a StripByteCounts and TileByteCounts Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2689
* libtiff/tif_ojpeg.c: fix potential memory leak in
OJPEGReadHeaderInfoSecTablesQTable, OJPEGReadHeaderInfoSecTablesDcTable
and OJPEGReadHeaderInfoSecTablesAcTable Patch by Nicolás Peña.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2670
* libtiff/tif_fax3.c: avoid crash in Fax3Close() on empty file.
Patch by Alan Coopersmith + complement by myself. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2673
* libtiff/tif_read.c: TIFFFillStrip(): add limitation to the number
of bytes read in case td_stripbytecount[strip] is bigger than
reasonable, so as to avoid excessive memory allocation.
* libtiff/tif_zip.c, tif_pixarlog.c, tif_predict.c: fix memory
leak when the underlying codec (ZIP, PixarLog) succeeds its
setupdecode() method, but PredictorSetup fails. Credit to OSS-Fuzz
(locally run, on GDAL)
* libtiff/tif_read.c: TIFFFillStrip() and TIFFFillTile(): avoid
excessive memory allocation in case of shorten files. Only
effective on 64 bit builds and non-mapped cases. Credit to
OSS-Fuzz (locally run, on GDAL)
* libtiff/tif_read.c: TIFFFillStripPartial() / TIFFSeek(), avoid
potential integer overflows with read_ahead in CHUNKY_STRIP_READ_SUPPORT
mode. Should especially occur on 32 bit platforms.
* libtiff/tif_read.c: TIFFFillStripPartial(): avoid excessive
memory allocation in case of shorten files. Only effective on
64 bit builds. Credit to OSS-Fuzz (locally run, on GDAL)
* libtiff/tif_read.c: update tif_rawcc in CHUNKY_STRIP_READ_SUPPORT
mode with tif_rawdataloaded when calling TIFFStartStrip() or
TIFFFillStripPartial(). This avoids reading beyond tif_rawdata
when bytecount > tif_rawdatasize. Fixes

to OSS-Fuzz
* libtiff/tif_pixarlog.c, tif_luv.c: avoid potential int32 overflows
in multiply_ms() and add_ms(). Fixes

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1563
Credit to OSS-Fuzz
* libtiff/tif_luv.c: LogL16InitState(): avoid excessive memory
allocation when RowsPerStrip tag is missing. Credit to OSS-Fuzz
(locally run, on GDAL)
* libtiff/tif_lzw.c: update dec_bitsleft at beginning of LZWDecode(),
and update tif_rawcc at end of LZWDecode(). This is needed to
properly work with the latest chnges in tif_read.c in
CHUNKY_STRIP_READ_SUPPORT mode.
* libtiff/tif_pixarlog.c: PixarLogDecode(): resync tif_rawcp with
next_in and tif_rawcc with avail_in at beginning and end of
function, similarly to what is done in LZWDecode(). Likely needed
so that it works properly with latest chnges in tif_read.c in
CHUNKY_STRIP_READ_SUPPORT mode. But untested...
* libtiff/tif_getimage.c: initYCbCrConversion(): add basic validation
of luma and refBlackWhite coefficients (just check they are not
NaN for now), to avoid potential float to int overflows. Fixes
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1663 Credit
to OSS Fuzz
* libtiff/tif_read.c: _TIFFVSetField(): fix outside range cast of
double to float. Credit to Google Autofuzz project

MAJOR CHANGES:
• The libtiff tools bmp2tiff, gif2tiff, ras2tiff, sgi2tiff, sgisv, and ycbcr
are completely removed from the distribution. These tools were written in
the late 1980s and early 1990s for test and demonstration purposes. In some
cases the tools were never updated to support updates to the file format,
or the file formats are now rarely used. In all cases these tools increased
the libtiff security and maintenance exposure beyond the value offered by
the tool.
CHANGES IN LIBTIFF:
• libtiff/tif_dirread.c: in TIFFFetchNormalTag(), do not dereference NULL
pointer when values of tags with TIFF_SETGET_C16_ASCII /
TIFF_SETGET_C32_ASCII access are 0-byte arrays. Fixes http://
bugzilla.maptools.org/show_bug.cgi?id=2593 (regression introduced by
previous fix done on 2016-11-11 for CVE-2016-9297). Reported by Henri Salo.
Assigned as CVE-2016-9448
• libtiff/tif_aux.c: fix crash in TIFFVGetFieldDefaulted() when requesting
Predictor tag and that the zip/lzw codec is not configured. Fixes http://
bugzilla.maptools.org/show_bug.cgi?id=2591
• libtiff/tif_dirread.c: in TIFFFetchNormalTag(), make sure that values of
tags with TIFF_SETGET_C16_ASCII / TIFF_SETGET_C32_ASCII access are null
terminated, to avoid potential read outside buffer in _TIFFPrintField().
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2590
• libtiff/tif_dirread.c: reject images with OJPEG compression that have no
TileOffsets/StripOffsets tag, when OJPEG compression is disabled. Prevent
null pointer dereference in TIFFReadRawStrip1() and other functions that
expect td_stripbytecount to be non NULL. Fixes http://bugzilla.maptools.org
/show_bug.cgi?id=2585
• 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
http://bugzilla.maptools.org/show_bug.cgi?id=2587 (CVE-2016-9273)
• libtiff/tif_predict.h, libtiff/tif_predict.c: Replace assertions by runtime
checks to avoid assertions in debug mode, or buffer overflows in release
mode. Can happen when dealing with unusual tile size like YCbCr with
subsampling. Reported as MSVR 35105 by Axel Souchet & Vishal Chauhan from
the MSRC Vulnerabilities & Mitigations
• libtiff/tif_dir.c: discard values of SMinSampleValue and SMaxSampleValue
when they have been read and the value of SamplesPerPixel is changed
afterwards (like when reading a OJPEG compressed image with a missing
SamplesPerPixel tag, and whose photometric is RGB or YCbCr, forcing
SamplesPerPixel being 3). Otherwise when rewriting the directory (for
example with tiffset, we will expect 3 values whereas the array had been
allocated with just one), thus causing a out of bound read access. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2500 (CVE-2014-8127,
duplicate: CVE-2016-3658)
• libtiff/tif_dirwrite.c: avoid null pointer dereference on td_stripoffset
when writing directory, if FIELD_STRIPOFFSETS was artificially set for a
hack case in OJPEG case. Fixes http://bugzilla.maptools.org/show_bug.cgi?id
=2500 (CVE-2014-8127, duplicate: CVE-2016-3658)
• libtiff/tif_getimage.c (TIFFRGBAImageOK): Reject attempts to read floating
point images.
• 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."
• libtiff/tif_pixarlog.c: fix out-of-bounds write vulnerabilities in heap
allocated buffers. Reported as MSVR 35094. Discovered by Axel Souchet and
Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.
• 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.
Discovered by Axel Souchet & Vishal Chauhan & Suha Can from the MSRC
Vulnerabilities & Mitigations team.
• libtiff/tif_pixarlog.c: Fix write buffer overflow in PixarLogEncode if more
input samples are provided than expected by PixarLogSetupEncode. Idea based
on libtiff-CVE-2016-3990.patch from libtiff-4.0.3-25.el7_2.src.rpm by
Nikola Forro, but with different and simpler check. (bugzilla #2544)
• libtiff/tif_read.c: Fix out-of-bounds read on memory-mapped files in
TIFFReadRawStrip1() and TIFFReadRawTile1() when stripoffset is beyond
tmsize_t max value (reported by Mathias Svensson)
• libtiff/tif_read.c: make TIFFReadEncodedStrip() and TIFFReadEncodedTile()
directly use user provided buffer when no compression (and other
conditions) to save a memcpy()
• libtiff/tif_write.c: make TIFFWriteEncodedStrip() and TIFFWriteEncodedTile
() directly use user provided buffer when no compression to save a memcpy
().
• libtiff/tif_luv.c: validate that for COMPRESSION_SGILOG and
PHOTOMETRIC_LOGL, there is only one sample per pixel. Avoid potential
invalid memory write on corrupted/unexpected images when using the
TIFFRGBAImageBegin() interface (reported by Clay Wood)
• libtiff/tif_pixarlog.c: fix potential buffer write overrun in
PixarLogDecode() on corrupted/unexpected images (reported by Mathias
Svensson) (CVE-2016-5875)
• libtiff/libtiff.def: Added _TIFFMultiply32 and _TIFFMultiply64 to
libtiff.def
• libtiff/tif_config.vc.h (HAVE_SNPRINTF): Add a '1' to the HAVE_SNPRINTF
definition.
• libtiff/tif_config.vc.h (HAVE_SNPRINTF): Applied patch by Edward Lam to
define HAVE_SNPRINTF for Visual Studio 2015.
• libtiff/tif_dirread.c: when compiled with DEFER_STRILE_LOAD, fix
regression, introduced on 2014-12-23, when reading a one-strip file without
a StripByteCounts tag. GDAL #6490
• libtiff/*: upstream typo fixes (mostly contributed by Kurt Schwehr) coming
from GDAL internal libtiff
• libtiff/tif_fax3.h: make Param member of TIFFFaxTabEnt structure a uint16
to reduce size of the binary.
• libtiff/tif_read.c, tif_dirread.c: fix indentation issues raised by GCC 6
-Wmisleading-indentation
• libtiff/tif_pixarlog.c: avoid zlib error messages to pass a NULL string to
%s formatter, which is undefined behaviour in sprintf().
• libtiff/tif_next.c: fix potential out-of-bound write in NeXTDecode()
triggered by http://lcamtuf.coredump.cx/afl/vulns/libtiff5.tif (bugzilla #
2508)
• libtiff/tif_luv.c: fix potential out-of-bound writes in decode functions in
non debug builds by replacing assert()s by regular if checks (bugzilla #
2522). Fix potential out-of-bound reads in case of short input data.
• libtiff/tif_getimage.c: fix out-of-bound reads in TIFFRGBAImage interface
in case of unsupported values of SamplesPerPixel/ExtraSamples for LogLUV /
CIELab. Add explicit call to TIFFRGBAImageOK() in TIFFRGBAImageBegin(). Fix
CVE-2015-8665 reported by limingxing and CVE-2015-8683 reported by zzf of
Alibaba.
• libtiff/tif_dirread.c: workaround false positive warning of Clang Static
Analyzer about null pointer dereference in TIFFCheckDirOffset().
• libtiff/tif_fax3.c: remove dead assignment in Fax3PutEOLgdal(). Found by
Clang Static Analyzer
• libtiff/tif_dirwrite.c: fix truncation to 32 bit of file offsets in
TIFFLinkDirectory() and TIFFWriteDirectorySec() when aligning directory
offsets on a even offset (affects BigTIFF). This was a regression of the
changeset of 2015-10-19.
• libtiff/tif_write.c: TIFFWriteEncodedStrip() and TIFFWriteEncodedTile()
should return -1 in case of failure of tif_encodestrip() as documented
• libtiff/tif_dumpmode.c: DumpModeEncode() should return 0 in case of failure
so that the above mentionned functions detect the error.
• libtiff/*.c: fix MSVC warnings related to cast shortening and assignment
within conditional expression
• libtiff/*.c: fix clang -Wshorten-64-to-32 warnings
• libtiff/tif_dirread.c: prevent reading ColorMap or TransferFunction if
BitsPerPixel > 24, so as to avoid huge memory allocation and file read
attempts
• libtiff/tif_dirread.c: remove duplicated assignment (reported by Clang
static analyzer)
• libtiff/tif_dir.c, libtiff/tif_dirinfo.c, libtiff/tif_compress.c, libtiff/
tif_jpeg_12.c: suppress warnings about 'no previous declaration/prototype'
• libtiff/tiffiop.h, libtiff/tif_dirwrite.c: suffix constants by U to fix
'warning: negative integer implicitly converted to unsigned type' warning
(part of -Wconversion)
• libtiff/tif_dir.c, libtiff/tif_dirread.c, libtiff/tif_getimage.c, libtiff/
tif_print.c: fix -Wshadow warnings (only in libtiff/)
CHANGES IN THE TOOLS:
• tools/Makefile.am: The libtiff tools bmp2tiff, gif2tiff, ras2tiff,
sgi2tiff, sgisv, and ycbcr are completely removed from the distribution.
The libtiff tools rgb2ycbcr and thumbnail are only built in the build tree
for testing. Old files are put in new 'archive' subdirectory of the source
repository, but not in distribution archives. These changes are made in
order to lessen the maintenance burden.
• tools/tiff2pdf.c: avoid undefined behaviour related to overlapping of
source and destination buffer in memcpy() call in t2p_sample_rgbaa_to_rgb()
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2577

writeBufferToSeparateStrips(), writeBufferToContigTiles() and
writeBufferToSeparateTiles() that could cause heap buffer overflows.
Reported by Henri Salo from Nixu Corporation. Fixes http://
bugzilla.maptools.org/show_bug.cgi?id=2592
• tools/tiffcrop.c: fix out-of-bound read of up to 3 bytes in
readContigTilesIntoBuffer(). Reported as MSVR 35092 by Axel Souchet &
Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.
• tools/tiff2pdf.c: fix write buffer overflow of 2 bytes on JPEG compressed
images. Reported by Tyler Bohan of Cisco Talos as TALOS-CAN-0187 /
CVE-2016-5652. Also prevents writing 2 extra uninitialized bytes to the
file stream.
• tools/tiffcp.c: fix out-of-bounds write on tiled images with odd tile width
vs image width. Reported as MSVR 35103 by Axel Souchet and Vishal Chauhan
from the MSRC Vulnerabilities & Mitigations team.
• tools/tiff2pdf.c: fix read -largely- outsize of buffer in
t2p_readwrite_pdf_image_tile(), causing crash, when reading a JPEG

Vulnerabilities & Mitigations team.
• tools/tiff2pdf.c: fix out-of-bounds write vulnerabilities in heap allocate
buffer in t2p_process_jpeg_strip(). Reported as MSVR 35098. Discovered by
Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities & Mitigations
team.
• tools/tiff2bw.c: fix weight computation that could result of color value
overflow (no security implication). Fix bugzilla #2550. Patch by Frank
Freudenberg.

Changelog:
2015-06-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff 4.0.4 released.
* configure.ac: Add a HAVE_FOO Automake conditional for each
add-on library.
* test/Makefile.am (JPEG_DEPENDENT_CHECK_PROG): raw_decode
requires JPEG support to compile. Use Automake conditional to
only include it when JPEG support is available.
* html/build.html: Try to improve the nmake-based VC++ build
description.
* libtiff/tiffconf.vc.h: Build fixes based on testing.
* libtiff/tif_config.vc.h: Build fixes based on testing.
* libtiff/libtiff.def: TIFFRasterScanline does not exist so remove
export for it.
2015-06-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_config.vc.h: Make adjustments to match the new
definitions that configure produces, including for WIN64. Still
needs to be tested.
* configure.ac: For 64-bit MinGW, fix SSIZE_FORMAT formatting
specifier. 64-bit MinGW supports 'long long' but support for
'lld' is not assured by the run-time DLLs and so GCC warns.
Add TIFF_SIZE_T and TIFF_SIZE_FORMAT to provide a type definition
and printf format specifier to deal with printing values of
'size_t' type. In particular, this was necessary for WIN64.
Added a configure test for if the system headers provide 'optarg'
(normal case) and block out the many explicit 'extern' statements
in the utilities. This was found to be necessary under Windows
when getopt is in a DLL and the symbols are already imported with
dllimport via standard header files.
* test/raw_decode.c (XMD_H): Avoid conflicting typedefs for INT32
and boolean in MinGW build due to including jpeglib.h.
* test/rewrite_tag.c (main): Fix problem with location of variable
declaration.
* libtiff/libtiff.def: Added exports for TIFFGetConfiguredCODECs,
TIFFReadRGBAImageOriented, TIFFSetCompressionScheme,
TIFFSwabArrayOfTriples, TIFFVGetFieldDefaulted, _TIFFCheckRealloc,
TIFFRasterScanline, TIFFSetErrorHandlerExt,
TIFFSetWarningHandlerExt, TIFFNumberOfDirectories,
TIFFCreateCustomDirectory, TIFFCreateEXIFDirectory,
TIFFWriteCustomDirectory, _TIFFRewriteField as recommended by
Roger Leigh and justified by use in libtiff tests, documentation,
and changelog notes. Also sorted symbol list and removed
duplicate entries.
2015-06-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_getimage.c: Fix four Coverity issues related to
unintended sign extension.

2015-06-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_jpeg.c (JPEGDecode): Split JPEGDecode() into two
clean implementations in order to avoid pre-processor hell. Only
one of the implementations is used in a given build.
2015-06-08 Even Rouault <even.rouault at spatialys.com>
