"This update for ImageMagick fixes several issues.

These security issues were fixed :

  - CVE-2018-8804: The WriteEPTImage function allowed remote
    attackers to cause a denial of service (double free and
    application crash) or possibly have unspecified other
    impact via a crafted file (bsc#1086011).

  - CVE-2017-11524: The WriteBlob function allowed remote
    attackers to cause a denial of service (assertion
    failure and application exit) via a crafted file
    (bsc#1050087).

  - CVE-2017-18209: Prevent NULL pointer dereference in the
    GetOpenCLCachedFilesDirectory function caused by a
    memory allocation result that was not checked, related
    to GetOpenCLCacheDirectory (bsc#1083628).

  - CVE-2017-18211: Prevent NULL pointer dereference in the
    function saveBinaryCLProgram caused by a program-lookup
    result not being checked, related to CacheOpenCLKernel
    (bsc#1083634).

  - CVE-2017-9500: Prevent assertion failure in the function
    ResetImageProfileIterator, which allowed attackers to
    cause a denial of service via a crafted file
    (bsc#1043290).

  - CVE-2017-14739: The AcquireResampleFilterThreadSet
    function mishandled failed memory allocation, which
    allowed remote attackers to cause a denial of service
    (NULL pointer Dereference in DistortImage in
    MagickCore/distort.c, and application crash) via
    unspecified vectors (bsc#1060382).

  - CVE-2017-16353: Prevent memory information disclosure in
    the DescribeImage function caused by a heap-based buffer
    over-read. The portion of the code containing the
    vulnerability is responsible for printing the IPTC
    Profile information contained in the image. This
    vulnerability can be triggered with a specially crafted
    MIFF file. There is an out-of-bounds buffer dereference
    because certain increments were never checked
    (bsc#1066170).

  - CVE-2017-16352: Prevent a heap-based buffer overflow in
    the 'Display visual image directory' feature of the
    DescribeImage() function. One possible way to trigger
    the vulnerability is to run the identify command on a
    specially crafted MIFF format file with the verbose flag
    (bsc#1066168).

  - CVE-2017-14314: Prevent off-by-one error in the
    DrawImage function that allowed remote attackers to
    cause a denial of service (DrawDashPolygon heap-based
    buffer over-read and application crash) via a crafted
    file (bsc#1058630).

  - CVE-2017-13768: Prevent NULL pointer dereference in the
    IdentifyImage function that allowed an attacker to
    perform denial of service by sending a crafted image
    file (bsc#1056434).

  - CVE-2017-14505: Fixed handling of NULL arrays, which
    allowed attackers to perform Denial of Service (NULL
    pointer dereference and application crash in
    AcquireQuantumMemory within MagickCore/memory.c) by
    providing a crafted Image File as input (bsc#1059735).

  - CVE-2018-7470: The IsWEBPImageLossless function allowed
    attackers to cause a denial of service (segmentation
    violation) via a crafted file (bsc#1082837).

  - CVE-2018-7443: The ReadTIFFImage function did not
    properly validate the amount of image data in a file,
    which allowed remote attackers to cause a denial of
    service (memory allocation failure in the
    AcquireMagickMemory function in MagickCore/memory.c)
    (bsc#1082792).

  - CVE-2017-15016: Prevent NULL pointer dereference
    vulnerability in ReadEnhMetaFile allowing for denial of
    service (bsc#1082291).

  - CVE-2017-15017: Prevent NULL pointer dereference
    vulnerability in ReadOneMNGImage allowing for denial of
    service (bsc#1082283).

  - CVE-2017-12692: The ReadVIFFImage function allowed
    remote attackers to cause a denial of service (memory
    consumption) via a crafted VIFF file (bsc#1082362).

  - CVE-2017-12693: The ReadBMPImage function allowed remote
    attackers to cause a denial of service (memory
    consumption) via a crafted BMP file (bsc#1082348). This
    update was imported from the SUSE:SLE-12:Update update
    project."

    SVG document, a different vulnerability than
