"This update for ImageMagick fixes several issues. These security
issues were fixed :

  - CVE-2017-1000476: A CPU exhaustion vulnerability was
    found in the function ReadDDSInfo in coders/dds.c, which
    allowed attackers to cause a denial of service
    (bsc#1074610).

  - CVE-2017-9409: The ReadMPCImage function in mpc.c
    allowed attackers to cause a denial of service (memory
    leak) via a crafted file (bsc#1042948).

  - CVE-2017-1000445: A NULL pointer dereference in the
    MagickCore component might have lead to denial of
    service (bsc#1074425).

  - CVE-2017-17680: Prevent a memory leak in the function
    ReadXPMImage in coders/xpm.c, which allowed attackers to
    cause a denial of service via a crafted XPM image file
    (a different vulnerability than CVE-2017-17882)
    (bsc#1072902).

  - CVE-2017-17882: Prevent a memory leak in the function
    ReadXPMImage in coders/xpm.c, which allowed attackers to
    cause a denial of service via a crafted XPM image file
    (a different vulnerability than CVE-2017-17680)
    (bsc#1074122).

  - CVE-2017-11449: coders/mpc did not enable seekable
    streams and thus could not validate blob sizes, which
    allowed remote attackers to cause a denial of service
    (application crash) or possibly have unspecified other
    impact via an image received from stdin (bsc#1049373).

  - CVE-2017-12430: A memory exhaustion in the function
    ReadMPCImage in coders/mpc.c allowed attackers to cause
    DoS (bsc#1052252).

  - CVE-2017-12642: Prevent a memory leak vulnerability in
    ReadMPCImage in coders\mpc.c via crafted file allowing
    for DoS (bsc#1052771).

  - CVE-2017-14249: A mishandled EOF check in ReadMPCImage
    in coders/mpc.c that lead to a division by zero in
    GetPixelCacheTileSize in MagickCore/cache.c allowed
    remote attackers to cause a denial of service via a
    crafted file (bsc#1058082).

  - Prevent memory leak via crafted file in pwp.c allowing
    for DoS (bsc#1051412)

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
