"This update for ImageMagick fixes the following issues :

CVE-2017-14997: ImageMagick allowed remote attackers to cause a denial
of service (excessive memory allocation) because of an integer
underflow in ReadPICTImage in coders/pict.c. (bsc#1112399)

CVE-2018-16644: A regression in the security fix for the pict coder
was fixed (bsc#1107609)

CVE-2017-11532: When ImageMagick processed a crafted file in convert,
it could lead to a Memory Leak in the WriteMPCImage() function in
coders/mpc.c. (bsc#1050129)

CVE-2017-11639: A regression in the security fix in the cip coder was
fixed (bsc#1050635)

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."
