"This update for ImageMagick fixes the following security issue :

CVE-2017-17934: Prevent memory leaks, related to MSLPopImage and
ProcessMSLScript, and associated with mishandling of MSLPushImage
calls (bsc#1074170).

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

CVE-2018-16323: ReadXBMImage left data uninitialized when processing
an XBM file that has a negative pixel value. If the affected code was
used as a library loaded into a process that includes sensitive
information, that information sometimes can be leaked via the image
data (bsc#1106855)

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-2018-16643: 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-2018-18024: Fixed an infinite loop in the ReadBMPImage function of
the coders/bmp.c file. Remote attackers could leverage this
vulnerability to cause a denial of service via a crafted bmp file
(bsc#1111069)

CVE-2018-18016: Fixed a memory leak in WritePCXImage (bsc#1111072)

CVE-2018-17965: Fixed a memory leak in WriteSGIImage (bsc#1110747)

CVE-2018-17966: Fixed a memory leak in WritePDBImage (bsc#1110746)

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
