The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3212-1 advisory.

    It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system     were tricked into opening a specially crafted image, a remote attacker could crash the application,     leading to a denial of service, or possibly execute arbitrary code with user privileges.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

Multiple memory corruption issues have been identified in libtiff and its associated tools.
