- Upgrade to upstream release 4.0.9
* Changes in the software configuration:
+ test/Makefile.am: Add some tests for tiff2bw.
+ .appveyor.yml, .travis.yml, build/travis-ci: apply patches
0001-ci-Travis-script-improvements.patch and
0002-ci-Invoke-helper-script-via-shell.patch by Roger Leigh
+ .travis.yml, build/travis-ci: new files from
0001-ci-Add-Travis-support-for-Linux-builds-with-Autoconf.patch
by Roger Leigh. This patch adds support for the Travis-CI
service.
+ .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.
+ test/tiffcp-lzw-compat.sh, test/images/quad-lzw-compat.tiff:
new files to test old-style LZW decompression
+ test/common.sh, Makefile.am, CMakeList.txt: updated with above
+ test/Makefile.am: add missing reference to
images/quad-lzw-compat.tiff to fix "make distcheck". Patch by
Roger Leigh
+ 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
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1844
+ libtiff/tif_getimage.c: initYCbCrConversion(): stricter
validation for refBlackWhite coefficients values. To avoid
invalid float->int32 conversion (when refBlackWhite[0] ==
2147483648.f) Fixes
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1907
+ 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
0063-Handle-properly-CODEC-specific-tags.patch
(http://bugzilla.maptools.org/show_bug.cgi?id=2580) by Raphaël
Hertzog.

http://bugzilla.maptools.org/show_bug.cgi?id=2433
+ 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
copy.
+ 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.
(https://trac.osgeo.org/gdal/ticket/6924)
+ 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.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2215
+ libtiff/tif_getimage.c: avoid many (harmless) unsigned int
overflows.
+ 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
TIFF_NOSANITIZE_UNSIGNED_INT_OVERFLOW
+ libtiff/tif_dirread.c: avoid unsigned int overflow in
EstimateStripByteCounts()
+ 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
http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf
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
http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf
This limitation may be overriden by setting the
LIBTIFF_ALLOW_LARGE_LIBJPEG_MEM_ALLOC environment variable, or
recompiling libtiff with a custom value of
TIFF_LIBJPEG_LARGEST_MEM_ALLOC macro.
+ libtiff/tif_jbig.c: fix memory leak in error code path of
JBIGDecode()
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2706
(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
2017-05-10)
+ libtiff/tif_getimage.c: use
_TIFFReadEncodedStripAndAllocBuffer(). Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2708 and
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2433
+ 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.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2712
+ 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
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2454
+ 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().
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2470
+ 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
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2554
+ 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
instance.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2713
+ tools/tiff2pdf.c: prevent heap buffer overflow write in "Raw"
mode on PlanarConfig=Contig input images. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2715
+ libtiff/tif_read.c: TIFFFillStrip() / TIFFFillTile().
Complementary fix for
http://bugzilla.maptools.org/show_bug.cgi?id=2708 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
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2350
+ 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
http://bugzilla.maptools.org/show_bug.cgi?id=2675
(CVE-2017-12944, bsc#1054594)
+ libtiff/tif_luv.c: LogLuvInitState(): avoid excessive memory
allocation when RowsPerStrip tag is missing. Fixes
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2683
+ 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
http://bugzilla.maptools.org/show_bug.cgi?id=2637 and
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2691
+ libtiff/tif_luv.c: further reduce memory requirements for
temporary buffer when RowsPerStrip >= image_length in
LogLuvInitState() and LogL16InitState(). Fixes
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2700
+ libtiff/tif_dirwrite.c: replace assertion related to not
finding the SubIFD tag by runtime check (in
TIFFWriteDirectorySec()) Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2727
+ 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
http://bugzilla.maptools.org/show_bug.cgi?id=2728
+ 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.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2726
+ libtiff/tif_dirread.c: add NULL check to avoid likely false
positive null-pointer dereference warning by CLang Static
Analyzer.
+ libtiff/libtiff.def: add TIFFReadRGBAStripExt and
TIFFReadRGBATileExt Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2735
+ libtiff/tif_jpeg.c: add compatibility with libjpeg-turbo
1.5.2 that honours max_memory_to_use > 0. Cf
https://github.com/libjpeg-turbo/libjpeg-turbo/issues/162
+ libtiff/tif_getimage.c: avoid floating point division by zero
in initCIELabConversion() Fixes
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3733
* Changes in the tools:
+ tools/tiff2pdf.c: prevent heap buffer overflow write in "Raw"
mode on PlanarConfig=Contig input images. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2715
+ 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 fstrba@suse.com
- Upgrade to upstream release 4.0.8
* libtiff/tif_getimage.c, libtiff/tif_open.c

invalidPrintfArgType_uint warnings)
* libtiff/tif_read.c, libtiff/tiffiop.h

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

upper level read routines treat it accordingly. (linked to the
test case of 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. Fixes

+ 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.

* 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

there is only one sample per pixel. Avoid potential invalid
memory write on corrupted/unexpected images when using the
TIFFRGBAImageBegin() interface

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()). Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2587
(CVE-2016-9273, bsc#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
