CVE-2018-16643 (opens in a new tab)How to fix?
Upgrade SLES:15.0 ImageMagick to version 7.0.7.34-3.24.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ImageMagick package and not the ImageMagick package as distributed by SLES.
See How to fix? for SLES:15.0 relevant fixed versions and status.
The functions ReadDCMImage in coders/dcm.c, ReadPWPImage in coders/pwp.c, ReadCALSImage in coders/cals.c, and ReadPICTImage in coders/pict.c in ImageMagick 7.0.8-4 do not check the return value of the fputc function, which allows remote attackers to cause a denial of service via a crafted image file.
