    Description:

    This update for tiff to version 4.0.8 fixes a several bugs and security
    issues:

    These security issues were fixed:

    - CVE-2017-7595: The JPEGSetupEncode function allowed remote attackers to
    cause a denial of service (divide-by-zero error and application crash)
    via a crafted image (bsc#1033127).
    - CVE-2016-10371: The TIFFWriteDirectoryTagCheckedRational function
    allowed remote attackers to cause a denial of service (assertion failure
    and application exit) via a crafted TIFF file (bsc#1038438).
    - CVE-2017-7598: Error in tif_dirread.c allowed remote attackers to cause
    a denial of service (divide-by-zero error and application crash) via a
    crafted image (bsc#1033118).
    - CVE-2017-7596: Undefined behavior because of floats outside their
    expected value range, which allowed remote attackers to cause a denial
    of service (application crash) or possibly have unspecified other impact
    via a crafted image (bsc#1033126).
    - CVE-2017-7597: Undefined behavior because of floats outside their
    expected value range, which allowed remote attackers to cause a denial
    of service (application crash) or possibly have unspecified other impact
    via a crafted image (bsc#1033120).
    - CVE-2017-7599: Undefined behavior because of shorts outside their
    expected value range, which allowed remote attackers to cause a denial
    of service (application crash) or possibly have unspecified other impact
    via a crafted image (bsc#1033113).
    - CVE-2017-7600: Undefined behavior because of chars outside their
    expected value range, which allowed remote attackers to cause a denial
    of service (application crash) or possibly have unspecified other impact
    via a crafted image (bsc#1033112).
    - CVE-2017-7601: Because of a shift exponent too large for 64-bit type
    long undefined behavior was caused, which allowed remote attackers to
    cause a denial of service (application crash) or possibly have
    unspecified other impact via a crafted image (bsc#1033111).
    - CVE-2017-7602: Prevent signed integer overflow, which allowed remote
    attackers to cause a denial of service (application crash) or possibly
    have unspecified other impact via a crafted image (bsc#1033109).
    - CVE-2017-7592: The putagreytile function had a left-shift undefined
    behavior issue, which might allowed remote attackers to cause a denial
    of service (application crash) or possibly have unspecified other impact
    via a crafted image (bsc#1033131).
    - CVE-2017-7593: Ensure that tif_rawdata is properly initialized, to
    prevent remote attackers to obtain sensitive information from process
    memory via a crafted image (bsc#1033129).
    - CVE-2017-7594: The OJPEGReadHeaderInfoSecTablesDcTable function allowed
    remote attackers to cause a denial of service (memory leak) via a
    crafted image (bsc#1033128).
    - CVE-2017-9403: Prevent memory leak in function
    TIFFReadDirEntryLong8Array, which allowed attackers to cause a denial of
    service via a crafted file (bsc#1042805).
    - CVE-2017-9404: Fixed memory leak vulnerability in function
    OJPEGReadHeaderInfoSecTablesQTable, which allowed attackers to cause a
    denial of service via a crafted file (bsc#1042804).

    These various other issues were fixed:

    - Fix uint32 overflow in TIFFReadEncodedStrip() that caused an integer
    division by zero. Reported by Agostino Sarubbo.
    - 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.
    - 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()
    - make OJPEGDecode() early exit in case of failure in OJPEGPreDecode().
    This will avoid a divide by zero, and potential other issues.
    - fix misleading indentation as warned by GCC.
    - 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.
    - add TIFFReadRGBAStripExt() and TIFFReadRGBATileExt() variants
    of the functions without ext, with an extra argument to control the
    stop_on_error behaviour.
    - fix potential memory leaks in error code path of TIFFRGBAImageBegin().
    - 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.
    - add _TIFFcalloc()
    - return 0 in Encode functions instead of -1 when TIFFFlushData1() fails.
    - 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).
    - in LZWPostEncode(), increase, if necessary, the code bit-width after
    flushing the remaining code and before emitting the EOI code.
    - fix memory leak in error code path of PixarLogSetupDecode().
    - fix potential memory leak in OJPEGReadHeaderInfoSecTablesQTable,
    OJPEGReadHeaderInfoSecTablesDcTable and
    OJPEGReadHeaderInfoSecTablesAcTable
    - avoid crash in Fax3Close() on empty file.
    - 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.
    - fix memory leak when the underlying codec (ZIP, PixarLog) succeeds its
    setupdecode() method, but PredictorSetup fails.
    - TIFFFillStrip() and TIFFFillTile(): avoid excessive memory allocation in
    case of shorten files. Only effective on 64 bit builds and non-mapped
    cases.
    - TIFFFillStripPartial() / TIFFSeek(), avoid potential integer
    overflows with read_ahead in CHUNKY_STRIP_READ_SUPPORT mode.
    - avoid excessive memory allocation in case of shorten files. Only
    effective on 64 bit builds.
    - update tif_rawcc in CHUNKY_STRIP_READ_SUPPORT mode with
    tif_rawdataloaded when calling TIFFStartStrip() or
    TIFFFillStripPartial().
    - avoid potential int32 overflow in TIFFYCbCrToRGBInit() Fixes
    - avoid potential int32 overflows in multiply_ms() and add_ms().
    - fix out-of-buffer read in PackBitsDecode() Fixes
    - LogL16InitState(): avoid excessive memory allocation when RowsPerStrip
    tag is missing.
    - 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.
    - 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.
    - initYCbCrConversion(): add basic validation of luma and refBlackWhite
    coefficients (just check they are not NaN for now), to avoid potential
    float to int overflows.
    - _TIFFVSetField(): fix outside range cast of double to float.
    - initYCbCrConversion(): check luma[1] is not zero to avoid division by
    zero
    - _TIFFVSetField(): fix outside range cast of double to float.
    - initYCbCrConversion(): check luma[1] is not zero to avoid division by
    zero.
    - initYCbCrConversion(): stricter validation for refBlackWhite
    coefficients values.
    - avoid uint32 underflow in cpDecodedStrips that can cause various issues,
    such as buffer overflows in the library.
    - fix readContigStripsIntoBuffer() in -i (ignore) mode so that the output
    buffer is correctly incremented to avoid write
    outside bounds.
    - add 3 extra bytes at end of strip buffer in
    readSeparateStripsIntoBuffer() to avoid read outside of heap allocated
    buffer.
    - fix integer division by zero when BitsPerSample is missing.
    - fix null pointer dereference in -r mode when the image has no
    StripByteCount tag.
    - avoid potential division by zero is BitsPerSamples tag is missing.
    - when TIFFGetField(, TIFFTAG_NUMBEROFINKS, ) is called, limit the return
    number of inks to SamplesPerPixel, so that code that parses ink names
    doesn't go past the end of the buffer.
    - avoid potential division by zero is BitsPerSamples tag is missing.
    - fix uint32 underflow/overflow that can cause heap-based buffer
    overflow.
    - replace assert( (bps % 8) == 0 ) by a non assert check.
    - fix 2 heap-based buffer overflows (in PSDataBW and PSDataColorContig).
    - prevent heap-based buffer overflow in -j mode on a paletted image.
    - fix wrong usage of memcpy() that can trigger unspecified behaviour.
    - avoid potential invalid memory read in t2p_writeproc.
    - avoid potential heap-based overflow in t2p_readwrite_pdf_image_tile().
    - remove extraneous TIFFClose() in error code path, that caused double
    free.
    - error out cleanly in cpContig2SeparateByRow and cpSeparate2ContigByRow
    if BitsPerSample != 8 to avoid heap based overflow.
    - avoid integer division by zero.
    - call TIFFClose() in error code paths.
    - emit appropriate message if the input file is empty.
    - close TIFF handle in error code path.
