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

  - Reachable Assertion in tiffcp in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted
    tiff file. For users that compile libtiff from sources, the fix is available with commit 5e180045.
    (CVE-2022-0865)

  - Unchecked Return Value to NULL Pointer Dereference in tiffcrop in libtiff 4.3.0 allows attackers to cause
    a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is
    available with commit f2b656e2. (CVE-2022-0907)

  - Divide By Zero error in tiffcrop in libtiff 4.3.0 allows attackers to cause a denial-of-service via a
    crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f8d0f9aa.
    (CVE-2022-0909)

  - Out-of-bounds Read error in tiffcp in libtiff 4.3.0 allows attackers to cause a denial-of-service via a
    crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 408976c4.
    (CVE-2022-0924)

  - stack-buffer-overflow in tiffcp.c in main(). (CVE-2022-1355)
