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

  - A heap-based buffer overflow flaw was found in libtiff
    in the handling of TIFF images in libtiff's TIFF2PDF
    tool. A specially crafted TIFF file can lead to
    arbitrary code execution. The highest threat from this
    vulnerability is to confidentiality, integrity, as well
    as system availability.(CVE-2020-35524)

  - An integer overflow flaw was found in libtiff that
    exists in the tif_getimage.c file. This flaw allows an
    attacker to inject and execute arbitrary code when a
    user opens a crafted TIFF file. The highest threat from
    this vulnerability is to confidentiality, integrity, as
    well as system availability.(CVE-2020-35523)

  - In LibTIFF 4.0.7, a memory leak vulnerability was found
    in the function OJPEGReadHeaderInfoSecTablesQTable in
    tif_ojpeg.c, which allows attackers to cause a denial
    of service via a crafted file.(CVE-2017-9404)

  - 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)

  - 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)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
