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

  - ImageMagick before 7.0.8-50 has a 'use of uninitialized
    value' vulnerability in the function ReadCUTImage in
    coders/cut.c.(CVE-2019-13135)

  - ImageMagick 7.0.8-50 Q16 has a heap-based buffer
    over-read at MagickCore/threshold.c in
    AdaptiveThresholdImage because a width of zero is
    mishandled.(CVE-2019-13295)

  - ImageMagick 7.0.8-50 Q16 has a heap-based buffer
    over-read at MagickCore/threshold.c in
    AdaptiveThresholdImage because a height of zero is
    mishandled.(CVE-2019-13297)

  - ImageMagick 7.0.8-50 Q16 has a heap-based buffer
    overflow at MagickCore/statistic.c in EvaluateImages
    because of mishandling columns.(CVE-2019-13300)

  - ImageMagick 7.0.8-50 Q16 has a stack-based buffer
    overflow at coders/pnm.c in WritePNMImage because of a
    misplaced assignment.(CVE-2019-13304)

  - ImageMagick 7.0.8-34 has a 'use of uninitialized value'
    vulnerability in the ReadPANGOImage function in
    coders/pango.c.(CVE-2019-12978)

  - ImageMagick 7.0.8-34 has a 'use of uninitialized value'
    vulnerability in the SyncImageSettings function in
    MagickCore/image.c. This is related to AcquireImage in
    magick/image.c.(CVE-2019-12979)
