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

  - The cineon parsing component in ImageMagick 7.0.8-26
    Q16 allows attackers to cause a denial-of-service
    (uncontrolled resource consumption) by crafting a
    Cineon image with an incorrect claimed image size. This
    occurs because ReadCINImage in coders/cin.c lacks a
    check for insufficient image data in a
    file.(CVE-2019-11470)

  - In ImageMagick before 7.0.8-8, a NULL pointer
    dereference exists in the CheckEventLogging function in
    MagickCore/log.c.(CVE-2018-16328)

  - In ImageMagick 7.0.8-11 Q16, a tiny input file 0x50
    0x36 0x36 0x36 0x36 0x4c 0x36 0x38 0x36 0x36 0x36 0x36
    0x36 0x36 0x1f 0x35 0x50 0x00 can result in a hang of
    several minutes during which CPU and memory resources
    are consumed until ultimately an attempted large memory
    allocation fails. Remote attackers could leverage this
    vulnerability to cause a denial of service via a
    crafted file.(CVE-2018-15607)

  - The ReadMATImageV4 function in coders/mat.c in
    ImageMagick 7.0.8-7 uses an uninitialized variable,
    leading to memory corruption.(CVE-2018-14551)

  - There is a memory leak in the function WriteMSLImage of
    coders/msl.c in ImageMagick 7.0.8-13 Q16, and the
    function ProcessMSLScript of coders/msl.c in
    GraphicsMagick before 1.3.31.(CVE-2018-18544)

"Due to a large number of issues discovered in GhostScript that prevent
it from being used by ImageMagick safely, this update includes a
default policy change that disables support for the Postscript and PDF
formats in ImageMagick. This policy can be overridden if necessary by
using an alternate ImageMagick policy configuration.

It was discovered that several memory leaks existed when handling
certain images in ImageMagick. An attacker could use this to cause a
denial of service. (CVE-2018-14434, CVE-2018-14435, CVE-2018-14436,
CVE-2018-14437, CVE-2018-16640, CVE-2018-16750)

It was discovered that ImageMagick did not properly initialize a
variable before using it when processing MAT images. An attacker could
use this to cause a denial of service or possibly execute arbitrary
code. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-14551)

It was discovered that an information disclosure vulnerability existed
in ImageMagick when processing XBM images. An attacker could use this
to expose sensitive information. (CVE-2018-16323)

It was discovered that an out-of-bounds write vulnerability existed in
ImageMagick when handling certain images. An attacker could use this
to cause a denial of service or possibly execute arbitrary code.
(CVE-2018-16642)

It was discovered that ImageMagick did not properly check for errors
in some situations. An attacker could use this to cause a denial of
service. (CVE-2018-16643)

It was discovered that ImageMagick did not properly validate image
meta data in some situations. An attacker could use this to cause a
denial of service. (CVE-2018-16644)

It was discovered that ImageMagick did not prevent excessive memory
allocation when handling certain image types. An attacker could use
this to cause a denial of service. (CVE-2018-16645)

Sergej Schumilo and Cornelius Aschermann discovered that ImageMagick
did not properly check for NULL in some situations when processing PNG
images. An attacker could use this to cause a denial of service.
(CVE-2018-16749)

USN-3681-1 fixed vulnerabilities in Imagemagick. Unfortunately, the
fix for CVE-2017-13144 introduced a regression in ImageMagick in
Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. This update reverts the fix for
CVE-2017-13144 for those releases.

We apologize for the inconvenience.
