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

  - The DCM reader in ImageMagick before 6.9.4-5 and 7.x
    before 7.0.1-7 allows remote attackers to have
    unspecified impact by leveraging lack of validation of
    (1) pixel.red, (2) pixel.green, and (3)
    pixel.blue.(CVE-2016-5691)

  - The ReadDCMImage function in DCM reader in ImageMagick
    before 6.9.4-5 and 7.x before 7.0.1-7 allows remote
    attackers to have unspecified impact via vectors
    involving the for statement in computing the pixel
    scaling table.(CVE-2016-5690)

  - The DCM reader in ImageMagick before 6.9.4-5 and 7.x
    before 7.0.1-7 allows remote attackers to have
    unspecified impact by leveraging lack of NULL pointer
    checks.(CVE-2016-5689)

  - The VerticalFilter function in the DDS coder in
    ImageMagick before 6.9.4-3 and 7.x before 7.0.1-4
    allows remote attackers to have unspecified impact via
    a crafted DDS file, which triggers an out-of-bounds
    read.(CVE-2016-5687)

  - coders/ipl.c in ImageMagick allows remote attackers to
    have unspecific impact by leveraging a missing malloc
    check.(CVE-2016-10144)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
