Upgrade Debian:9 imagemagick to version 8:6.9.7.4+dfsg-11+deb9u10 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.
In ImageMagick 7.0.7-1 Q16, the PersistPixelCache function in magick/cache.c mishandles the pixel cache nexus, which allows remote attackers to cause a denial of service (NULL pointer dereference in the function GetVirtualPixels in MagickCore/cache.c) via a crafted file.
