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

  - Integer overflow in gd_io.c in the GD Graphics Library
    (aka libgd) before 2.2.4 allows remote attackers to
    have unspecified impact via vectors involving the
    number of horizontal and vertical chunks in an
    image.(CVE-2016-10168)

  - The gdImageCreateFromGd2Ctx function in gd_gd2.c in the
    GD Graphics Library (aka libgd) before 2.2.4 allows
    remote attackers to cause a denial of service
    (application crash) via a crafted image
    file.(CVE-2016-10167)

  - The dynamicGetbuf function in the GD Graphics Library
    (aka libgd) before 2.2.4 allows remote attackers to
    cause a denial of service (out-of-bounds read) via a
    crafted TIFF image.(CVE-2016-6911)

  - The output function in gd_gif_out.c in the GD Graphics
    Library (aka libgd) allows remote attackers to cause a
    denial of service (out-of-bounds read) via a crafted
    image.(CVE-2016-6161)
