Tiff was updated to version 4.0.7. This update fixes the following issues:

* libtiff/tif_aux.c
+ Fix crash in TIFFVGetFieldDefaulted() when requesting
Predictor tag and that the zip/lzw codec is not configured.
(http://bugzilla.maptools.org/show_bug.cgi?id=2591)
* libtiff/tif_compress.c
+ Make TIFFNoDecode() return 0 to indicate an error and make
upper level read routines treat it accordingly.
(http://bugzilla.maptools.org/show_bug.cgi?id=2517)
* 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.
(CVE-2014-8127, boo#914890, duplicate: CVE-2016-3658, boo#974840)
* 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.
(CVE-2016-9448, boo#1011103)
+ 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().
(CVE-2016-9297, boo#1010161)
+ Prevent reading ColorMap or TransferFunction if
BitsPerPixel > 24, so as to avoid huge memory allocation and
file read attempts
+ 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.
(http://bugzilla.maptools.org/show_bug.cgi?id=2585)
+ When compiled with DEFER_STRILE_LOAD, fix regression, when
reading a one-strip file without a StripByteCounts tag.
+ Workaround false positive warning of Clang Static Analyzer
about null pointer dereference in TIFFCheckDirOffset().
* 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
(CVE-2014-8127, boo#914890, duplicate: CVE-2016-3658,
boo#974840)
+ Fix truncation to 32 bit of file offsets in TIFFLinkDirectory()
and TIFFWriteDirectorySec() when aligning directory offsets on
an even offset (affects BigTIFF).
* libtiff/tif_dumpmode.c
+ DumpModeEncode() should return 0 in case of failure so that
the above mentionned functions detect the error.
* libtiff/tif_fax3.c
+ remove dead assignment in Fax3PutEOLgdal().
* libtiff/tif_fax3.h
+ make Param member of TIFFFaxTabEnt structure a uint16 to
reduce size of the binary.
* 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 and CVE-2015-8683.
+ TIFFRGBAImageOK: Reject attempts to read floating point images.
* 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
(http://bugzilla.maptools.org/show_bug.cgi?id=2522). Fix
potential out-of-bound reads in case of short input data.
+ 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
* libtiff/tif_next.c
+ Fix potential out-of-bound write in NeXTDecode()
(http://bugzilla.maptools.org/show_bug.cgi?id=2508)
* libtiff/tif_pixarlog.c
+ Avoid zlib error messages to pass a NULL string to %s
formatter, which is undefined behaviour in sprintf().
+ Fix out-of-bounds write vulnerabilities in heap allocated
buffers. Reported as MSVR 35094.
+ Fix potential buffer write overrun in PixarLogDecode() on
corrupted/unexpected images (CVE-2016-5875, boo#987351)
* libtiff/tif_predict.c
+ PredictorSetup: Enforce bits-per-sample requirements of
floating point predictor (3).
(CVE-2016-3622, boo#974449)
* 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.
* 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
+ Make TIFFReadEncodedStrip() and TIFFReadEncodedTile() directly
use user provided buffer when no compression (and other
conditions) to save a memcpy().
* 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()).
(CVE-2016-9273, boo#1010163)
* 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.
+ Make TIFFWriteEncodedStrip() and TIFFWriteEncodedTile()
directly use user provided buffer when no compression to save
a memcpy().
+ TIFFWriteEncodedStrip() and TIFFWriteEncodedTile() should
return -1 in case of failure of tif_encodestrip() as documented
* tools/fax2tiff.c
+ Fix segfault when specifying -r without argument.
(http://bugzilla.maptools.org/show_bug.cgi?id=2572)
* 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/tiff2bw.c
+ Fix weight computation that could result of color value
overflow (no security implication). Fix
http://bugzilla.maptools.org/show_bug.cgi?id=2550.
* tools/tiff2pdf.c
+ Avoid undefined behaviour related to overlapping of source and
destination buffer in memcpy() call in
t2p_sample_rgbaa_to_rgb()
(http://bugzilla.maptools.org/show_bug.cgi?id=2577)
+ Fix out-of-bounds write vulnerabilities in heap allocate buffer
in t2p_process_jpeg_strip(). Reported as MSVR 35098.
+ Fix potential integer overflows on 32 bit builds in
t2p_read_tiff_size()
(http://bugzilla.maptools.org/show_bug.cgi?id=2576)
+ Fix read -largely- outsize of buffer in
t2p_readwrite_pdf_image_tile(), causing crash, when reading a
JPEG compressed image with TIFFTAG_JPEGTABLES length being one.
(CVE-2016-9453, boo#1011107)
+ Fix write buffer overflow of 2 bytes on JPEG compressed images.
Also prevents writing 2 extra uninitialized bytes to the file
stream.
(TALOS-CAN-0187, CVE-2016-5652, boo#1007280)
* tools/tiffcp.c
+ Fix out-of-bounds write on tiled images with odd tile width vs
image width. Reported as MSVR 35103.
+ Fix read of undefined variable in case of missing required
tags. Found on test case of MSVR 35100.
* tools/tiffcrop.c
+ Avoid access outside of stack allocated array on a tiled
separate TIFF with more than 8 samples per pixel.
(CVE-2016-5321, CVE-2016-5323, boo#984813, boo#984815)
+ Fix memory leak in (recent) error code path.
+ Fix multiple uint32 overflows in writeBufferToSeparateStrips(),
writeBufferToContigTiles() and writeBufferToSeparateTiles()
that could cause heap buffer overflows.
(http://bugzilla.maptools.org/show_bug.cgi?id=2592)
+ Fix out-of-bound read of up to 3 bytes in
readContigTilesIntoBuffer(). Reported as MSVR 35092.
+ Fix read of undefined buffer in readContigStripsIntoBuffer()
due to uint16 overflow. Reported as MSVR 35100.
+ Fix various out-of-bounds write vulnerabilities in heap or
stack allocated buffers. Reported as MSVR 35093, MSVR 35096
and MSVR 35097.
+ readContigTilesIntoBuffer: Fix signed/unsigned comparison
warning.
* tools/tiffdump.c
+ Fix a few misaligned 64-bit reads warned by -fsanitize
+ ReadDirectory: Remove uint32 cast to_TIFFmalloc() argument
which resulted in Coverity report. Added more mutiplication
overflow checks
* tools/tiffinfo.c
+ Fix out-of-bound read on some tiled images.
(http://bugzilla.maptools.org/show_bug.cgi?id=2517)
+ TIFFReadContigTileData: Fix signed/unsigned comparison warning.
+ TIFFReadSeparateTileData: Fix signed/unsigned comparison
warning.
