Upgrade Debian:9 imagemagick to version 8:6.9.7.4+dfsg-11+deb9u9 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 Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tiff file.
