An exploitable heap-based buffer overflow exists in the handling of TIFF images in LibTIFF's TIFF2PDF tool. A crafted TIFF document can lead to a heap-based buffer overflow resulting in remote code execution. Vulnerability can be triggered via a saved TIFF file delivered by other means.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtiff: Heap-based buffer over-read in bmp2tiff (CVE-2017-9117)

  - LibTIFF prior to 4.0.4, as used in Apple iOS before 8.4 and OS X before 10.10.4 and other products, allows     remote attackers to cause a denial of service (out-of-bounds write) via a crafted TIFF image.
    (CVE-2014-8128)

  - Integer overflow in tools/bmp2tiff.c in LibTIFF before 4.0.4 allows remote attackers to cause a denial of     service (heap-based buffer over-read), or possibly obtain sensitive information from process memory, via     crafted width and length values in RLE4 or RLE8 data in a BMP file. (CVE-2015-8870)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtiff: Heap-based buffer over-read in bmp2tiff (CVE-2017-9117)

  - LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a     crafted TIFF image to the (1) checkInkNamesString function in tif_dir.c in the thumbnail tool, (2)     compresscontig function in tiff2bw.c in the tiff2bw tool, (3) putcontig8bitCIELab function in     tif_getimage.c in the tiff2rgba tool, LZWPreDecode function in tif_lzw.c in the (4) tiff2ps or (5)     tiffdither tool, (6) NeXTDecode function in tif_next.c in the tiffmedian tool, or (7)     TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool.

This update for tiff fixes the following issues :

  - CVE-2016-9453: The t2p_readwrite_pdf_image_tile function     allowed remote attackers to cause a denial of service     (out-of-bounds write and crash) or possibly execute     arbitrary code via a JPEG file with a TIFFTAG_JPEGTABLES     of length one (bsc#1011107).

  - CVE-2016-5652: An exploitable heap-based buffer overflow     existed in the handling of TIFF images in the TIFF2PDF     tool. A crafted TIFF document can lead to a heap-based     buffer overflow resulting in remote code execution.
    Vulnerability can be triggered via a saved TIFF file     delivered by other means (bsc#1007280).

  - CVE-2017-11335: There is a heap-based buffer overflow in     tools/tiff2pdf.c via a PlanarConfig=Contig image, which     caused a more than one hundred bytes out-of-bounds write     (related to the ZIPDecode function in tif_zip.c). A     crafted input may lead to a remote denial of service     attack or an arbitrary code execution attack     (bsc#1048937).

  - CVE-2016-9536: tools/tiff2pdf.c had an out-of-bounds     write vulnerabilities in heap allocated buffers in     t2p_process_jpeg_strip(). Reported as MSVR 35098, aka     't2p_process_jpeg_strip heap-buffer-overflow.'     (bsc#1011845)

  - CVE-2017-9935: In LibTIFF, there was a heap-based buffer     overflow in the t2p_write_pdf function in     tools/tiff2pdf.c. This heap overflow could lead to     different damages. For example, a crafted TIFF document     can lead to an out-of-bounds read in TIFFCleanup, an     invalid free in TIFFClose or t2p_free, memory corruption     in t2p_readwrite_pdf_image, or a double free in     t2p_free. Given these possibilities, it probably could     cause arbitrary code execution (bsc#1046077).

  - CVE-2017-17973: There is a heap-based use-after-free in     the t2p_writeproc function in tiff2pdf.c. (bsc#1074318)

  - CVE-2015-7554: The _TIFFVGetField function in tif_dir.c     allowed attackers to cause a denial of service (invalid     memory write and crash) or possibly have unspecified     other impact via crafted field data in an extension tag     in a TIFF image (bsc#960341).

  - CVE-2016-5318: Stack-based buffer overflow in the
    _TIFFVGetField function allowed remote attackers to     crash the application via a crafted tiff (bsc#983436).

  - CVE-2016-10095: Stack-based buffer overflow in the
    _TIFFVGetField function in tif_dir.c allowed remote     attackers to cause a denial of service (crash) via a     crafted TIFF file (bsc#1017690,).

  - CVE-2016-10268: tools/tiffcp.c allowed remote attackers     to cause a denial of service (integer underflow and     heap-based buffer under-read) or possibly have     unspecified other impact via a crafted TIFF image,     related to 'READ of size 78490' and     libtiff/tif_unix.c:115:23 (bsc#1031255)

  - An overlapping of memcpy parameters was fixed which     could lead to content corruption (bsc#1017691).

  - Fixed an invalid memory read which could lead to a crash     (bsc#1017692).

  - Fixed a NULL pointer dereference in TIFFReadRawData     (tiffinfo.c) that could crash the decoder (bsc#1017688).

Multiple vulnerabilities have been discovered in the libtiff library and the included tools tiff2rgba, rgb2ycbcr, tiffcp, tiffcrop, tiff2pdf and tiffsplit, which may result in denial of service, memory disclosure or the execution of arbitrary code.

There were additional vulnerabilities in the tools bmp2tiff, gif2tiff, thumbnail and ras2tiff, but since these were addressed by the libtiff developers by removing the tools altogether, no patches are available and those tools were also removed from the tiff package in Debian stable. The change had already been made in Debian stretch before and no applications included in Debian are known to rely on these scripts.
If you use those tools in custom setups, consider using a different conversion/thumbnailing tool.

The tiff library and tools were updated to version 4.0.7 fixing various bug and security issues.

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.

Version 4.0.2-6+deb7u7 introduced changes that resulted in libtiff being unable to write out tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

This problem manifested itself with errors like those: $ tiffcp -r 16
-c jpeg sample.tif out.tif _TIFFVGetField: out.tif: Invalid tag 'Predictor' (not supported by codec). _TIFFVGetField: out.tif: Invalid tag 'BadFaxLines' (not supported by codec). tiffcp:
tif_dirwrite.c:687: TIFFWriteDirectorySec: Assertion `0' failed.

For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u10.

We recommend that you upgrade your tiff packages.
