"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
    will lead to a remote denial of service
    attack.(CVE-2017-13727)The putagreytile function in
    tif_getimage.c in LibTIFF 4.0.7 has a left-shift
    undefined behavior issue, which might allow remote

    crafted image.(CVE-2017-7592)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)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)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)The JPEGSetupEncode function in
    tiff_jpeg.c in LibTIFF 4.0.7 allows remote attackers to
    cause a denial of service (divide-by-zero error and
    application crash) via a crafted
    image.(CVE-2017-7595)LibTIFF 4.0.7 has an 'outside the
    range of representable values of type float' undefined
    behavior issue, which might allow remote attackers to

    impact via a crafted image.(CVE-2017-7599)LibTIFF 4.0.7
    has an 'outside the range of representable values of
    type unsigned char' undefined behavior issue, which
    might allow remote attackers to cause a denial of
    service (application crash) or possibly have
    unspecified other impact via a crafted
    image.(CVE-2017-7600)tif_dirread.c in LibTIFF 4.0.7
    might allow remote attackers to cause a denial of
    service (divide-by-zero error and application crash)
    via a crafted image.(CVE-2017-7598)LibTIFF 4.0.7 has a
    'shift exponent too large for 64-bit type long'
    undefined behavior issue, which might allow remote
    attackers to cause a denial of service (application
    crash) or possibly have unspecified other impact via a
    crafted image.(CVE-2017-7601)LibTIFF 4.0.7 has a signed
    integer overflow, which might allow remote attackers to
    cause a denial of service (application crash) or

    image.(CVE-2017-7602)LibTIFF version 4.0.7 is
    vulnerable to a heap-based buffer over-read in
    tif_lzw.c resulting in DoS or code execution via a
    crafted bmp image to tools/bmp2tiff.(CVE-2017-5563)In
    LibTIFF 4.0.7, the program processes BMP images without
    verifying that biWidth and biHeight in the
    bitmap-information header match the actual input,
    leading to a heap-based buffer over-read in
    bmp2tiff.(CVE-2017-9117)In LibTIFF 4.0.7, a memory leak
    vulnerability was found in the function
    TIFFReadDirEntryLong8Array in tif_dirread.c, which
    allows attackers to cause a denial of service via a
    crafted file.(CVE-2017-9403)In LibTIFF 4.0.8, there is
    a memory leak in tif_jbig.c. A crafted TIFF document
    can lead to a memory leak resulting in a remote denial
    of service attack.(CVE-2017-9936)In LibTIFF 4.0.9, a
    heap-based buffer overflow occurs in the function
    LZWDecodeCompat in tif_lzw.c via a crafted TIFF file,

    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
    leak, as demonstrated by pal2rgb.(CVE-2019-6128)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)

    overflow in the tools/tiffcp resulting in DoS or code
    execution via a crafted BitsPerSample
    value.(CVE-2017-5225)
