"This update for ImageMagick fixes the following security issues :

CVE-2017-11532: Prevent a memory leak vulnerability in the
WriteMPCImage() function in coders/mpc.c via a crafted file allowing
for DoS (bsc#1050129)

CVE-2018-16750: Prevent memory leak in the formatIPTCfromBuffer
function (bsc#1108283)

CVE-2018-16749: Added missing NULL check in ReadOneJNGImage that
allowed an attacker to cause a denial of service (WriteBlob assertion
failure and application exit) via a crafted file (bsc#1108282)

CVE-2018-16642: The function InsertRow allowed remote attackers to
cause a denial of service via a crafted image file due to an
out-of-bounds write (bsc#1107616)

CVE-2018-16640: Prevent memory leak in the function ReadOneJNGImage
(bsc#1107619)

CVE-2018-16643: The functions ReadDCMImage, ReadPWPImage,
ReadCALSImage, and ReadPICTImage did check the return value of the
fputc function, which allowed remote attackers to cause a denial of
service via a crafted image file (bsc#1107612)

CVE-2018-16644: Added missing check for length in the functions
ReadDCMImage and ReadPICTImage, which allowed remote attackers to
cause a denial of service via a crafted image (bsc#1107609)

CVE-2018-16645: Prevent excessive memory allocation issue in the
functions ReadBMPImage and ReadDIBImage, which allowed remote
attackers to cause a denial of service via a crafted image file
(bsc#1107604)

CVE-2018-16413: Prevent heap-based buffer over-read in the
PushShortPixel function leading to DoS (bsc#1106989)

This update also relaxes the restrictions of use of Postscript like
formats to 'write' only. (bsc#1105592)

Note that Tenable Network Security has extracted the preceding
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."
