"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has libtiff packages installed that are affected
by multiple vulnerabilities:

  - Buffer overflow in the readextension function in
    gif2tiff.c in LibTIFF 4.0.6 allows remote attackers to
    cause a denial of service (application crash) via a
    crafted GIF file. (CVE-2016-3186)

  - Heap-based buffer overflow in the
    cpSeparateBufToContigBuf function in tiffcp.c in LibTIFF
    4.0.9 allows remote attackers to cause a denial of
    service (crash) or possibly have unspecified other
    impact via a crafted TIFF file. (CVE-2018-12900)

  - The TIFFWriteDirectorySec() function in tif_dirwrite.c
    in LibTIFF through 4.0.9 allows remote attackers to
    cause a denial of service (assertion failure and
    application crash) via a crafted file, a different
    vulnerability than CVE-2017-13726. (CVE-2018-10963)

  - TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a
    heap-based buffer over-read, as demonstrated by
    bmp2tiff. (CVE-2018-10779)

  - In LibTIFF 4.0.9, a heap-based buffer overflow occurs in
    the function LZWDecodeCompat in tif_lzw.c via a crafted
    TIFF file, as demonstrated by tiff2ps. (CVE-2018-8905)

  - A NULL Pointer Dereference occurs in the function
    TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when
    using the tiffinfo tool to print crafted TIFF
    information, a different vulnerability than
    CVE-2017-18013. (This affects an earlier part of the
    TIFFPrintDirectory function that was not addressed by
    the CVE-2017-18013 patch.) (CVE-2018-7456)

  - An issue was discovered in LibTIFF 4.0.9. There is a
    int32 overflow in multiply_ms in tools/ppm2tiff.c, which
    can cause a denial of service (crash) or possibly have
    unspecified other impact via a crafted image file.
    (CVE-2018-17100)

  - An issue was discovered in LibTIFF 4.0.9. There are two
    out-of-bounds writes in cpTags in tools/tiff2bw.c and
    tools/pal2rgb.c, which can cause a denial of service
    (application crash) or possibly have unspecified other
    impact via a crafted image file. (CVE-2018-17101)

  - LibTIFF 4.0.9 (with JBIG enabled) decodes arbitrarily-
    sized JBIG into a buffer, ignoring the buffer size,
    which leads to a tif_jbig.c JBIGDecode out-of-bounds
    write. (CVE-2018-18557)

  - An issue was discovered in LibTIFF 4.0.9. There is a
    NULL pointer dereference in the function LZWDecode in
    the file tif_lzw.c. (CVE-2018-18661)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version

"According to the versions of the libtiff packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - ** DISPUTED ** LibTIFF 4.0.8 has multiple memory leak
    vulnerabilities, which allow attackers to cause a
    denial of service (memory consumption), as demonstrated
    by tif_open.c, tif_lzw.c, and tif_aux.c. NOTE: Third
    parties were unable to reproduce the
    issue.(CVE-2017-16232)

  - _TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in
    LibTIFF through 4.0.10 mishandle Integer Overflow
    checks because they rely on compiler behavior that is
    undefined by the applicable C standards. This can, for
    example, lead to an application crash.(CVE-2019-14973)

  - An Invalid Address dereference was discovered in
    TIFFWriteDirectoryTagTransferfunction in
    libtiff/tif_dirwrite.c in LibTIFF 4.0.10, affecting the
    cpSeparateBufToContigBuf function in tiffcp.c. Remote
    attackers could leverage this vulnerability to cause a
    denial-of-service via a crafted tiff file. This is
    different from CVE-2018-12900.(CVE-2019-7663)

  - An issue was discovered in LibTIFF 4.0.9. There are two
    out-of-bounds writes in cpTags in tools/tiff2bw.c and
    tools/pal2rgb.c, which can cause a denial of service
    (application crash) or possibly have unspecified other
    impact via a crafted image file.(CVE-2018-17101)

  - An issue was discovered in LibTIFF 4.0.9. There is a
    int32 overflow in multiply_ms in tools/ppm2tiff.c,
    which can cause a denial of service (crash) or possibly
    have unspecified other impact via a crafted image
    file.(CVE-2018-17100)

  - An issue was discovered in LibTIFF 4.0.9. There is a
    NULL pointer dereference in the function LZWDecode in
    the file tif_lzw.c.(CVE-2018-18661)

  - Buffer overflow in the readgifimage function in
    gif2tiff.c in the gif2tiff tool in LibTIFF 4.0.6 allows
    remote attackers to cause a denial of service
    (segmentation fault) via a crafted gif
    file.(CVE-2016-5102)

  - Heap-based buffer overflow in the
    cpSeparateBufToContigBuf function in tiffcp.c in
    LibTIFF 4.0.9 allows remote attackers to cause a denial
    of service (crash) or possibly have unspecified other
    impact via a crafted TIFF file.(CVE-2018-12900)

  - In LibTIFF 4.0.9, there is a NULL pointer dereference
    in the TIFFWriteDirectorySec function in tif_dirwrite.c
    that will lead to a denial of service attack, as
    demonstrated by tiffset.(CVE-2018-19210)

  - LibTIFF 4.0.7 has an invalid read in the _TIFFVGetField
    function in tif_dir.c, which might allow remote
    attackers to cause a denial of service (crash) via a
    crafted TIFF file.(CVE-2017-9147)

  - LibTIFF 4.0.9 (with JBIG enabled) decodes
    arbitrarily-sized JBIG into a buffer, ignoring the
    buffer size, which leads to a tif_jbig.c JBIGDecode
    out-of-bounds write.(CVE-2018-18557)

  - Stack-based buffer overflow in the _TIFFVGetField
    function in libtiff 4.0.6 and earlier allows remote
    attackers to crash the application via a crafted
    tiff.(CVE-2016-5318)

  - The _TIFFFax3fillruns function in libtiff before 4.0.6
    allows remote attackers to cause a denial of service
    (divide-by-zero error and application crash) via a
    crafted Tiff image.(CVE-2016-5323)

  - The cvtClump function in the rgb2ycbcr tool in LibTIFF
    4.0.6 and earlier allows remote attackers to cause a
    denial of service (out-of-bounds write) by setting the
    '-v' option to -1.(CVE-2016-3624)

  - The DumpModeDecode function in libtiff 4.0.6 and
    earlier allows attackers to cause a denial of service
    (invalid read and crash) via a crafted tiff
    image.(CVE-2016-5321)

  - The rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows
    remote attackers to cause a denial of service
    (divide-by-zero) by setting the (1) v or (2) h
    parameter to 0.(CVE-2016-3623)

  - The TIFFFdOpen function in tif_unix.c in LibTIFF 4.0.10
    has a memory leak, as demonstrated by
    pal2rgb.(CVE-2019-6128)

  - The TIFFWriteDirectorySec() function in tif_dirwrite.c
    in LibTIFF through 4.0.9 allows remote attackers to
    cause a denial of service (assertion failure and
    application crash) via a crafted file, a different
    vulnerability than CVE-2017-13726.(CVE-2018-10963)

  - tif_getimage.c in LibTIFF through 4.0.10, as used in
    GDAL through 3.0.1 and other products, has an integer
    overflow that potentially causes a heap-based buffer
    overflow via a crafted RGBA image, related to a
    'Negative-size-param' condition.(CVE-2019-17546)

  - The _TIFFFax3fillruns function in libtiff before 4.0.6
    allows remote attackers to cause a denial of service
    (divide-by-zero error and application crash) via a
    crafted Tiff image.(CVE-2016-5323)

  - The cvtClump function in the rgb2ycbcr tool in LibTIFF
