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

  - There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an
    attacker to cause a denial-of-service through a crafted tiff file. (CVE-2020-18768)

  - loadImage() in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based use after free via a crafted
    TIFF image. (CVE-2023-26965)

  - A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to a
    buffer overflow in the Fax3Encode function in libtiff/tif_fax3.c, resulting in a denial of service.
    (CVE-2023-3618)

  - LibTIFF is vulnerable to an integer overflow. This flaw allows remote attackers to cause a denial of
    service (application crash) or possibly execute an arbitrary code via a crafted tiff image, which triggers
    a heap-based buffer overflow. (CVE-2023-40745)

  - A vulnerability was found in libtiff due to multiple potential integer overflows in raw2tiff.c. This flaw
    allows remote attackers to cause a denial of service or possibly execute an arbitrary code via a crafted
    tiff image, which triggers a heap-based buffer overflow. (CVE-2023-41175)
