"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)

    heap-based buffer over-read, as demonstrated by
    bmp2tiff.(CVE-2018-10779)

  - The OJPEGReadHeaderInfoSecTablesDcTable function in
    tif_ojpeg.c in LibTIFF 4.0.7 allows remote attackers to
    cause a denial of service (memory leak) via a crafted
    image.(CVE-2017-7594)

  - LibTIFF 4.0.7 allows remote attackers to cause a denial
    of service (divide-by-zero error and application crash)
    via a crafted TIFF image, related to
    libtiff/tif_read.c:351:22.(CVE-2016-10266)

  - 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)

  - tif_read.c in LibTIFF 4.0.7 does not ensure that
    tif_rawdata is properly initialized, which might allow
    remote attackers to obtain sensitive information from
    process memory via a crafted image.(CVE-2017-7593)

  - 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)

  - _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)

  - 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)

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

  - The libtiff package contains a library of functions for
    manipulating TIFF (Tagged Image File Format) image
    format files. TIFF is a widely used file format for
    bitmapped images. TIFF files usually end in the .tif
    extension and they are often quite large. The libtiff
    package should be installed if you need to manipulate
    TIFF format image files. Security Fix(es):There is a
    reachable assertion abort in the function
    TIFFWriteDirectoryTagSubifd() in LibTIFF 4.0.8, related
    to tif_dirwrite.c and a SubIFD tag. A crafted input

    rely on compiler behavior that is undefined by the
    applicable C standards. This can, for example, lead to
    an application crash.(CVE-2019-14973)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)** 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)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)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 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)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)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)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 DumpModeDecode function in
    libtiff 4.0.6 and earlier allows attackers to cause a

    before 4.0.7 allows remote attackers to cause a denial
    of service (crash) or possibly obtain sensitive
    information via a negative index in a file-content
    buffer.(CVE-2016-6223)Integer overflow in the
    writeBufferToSeparateStrips function in tiffcrop.c in
    LibTIFF before 4.0.7 allows remote attackers to cause a
    denial of service (out-of-bounds read) via a crafted
    tif file.(CVE-2016-9532)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)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)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)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)The TIFFFdOpen
    function in tif_unix.c in LibTIFF 4.0.10 has a memory
