Upgrade Debian:unstable imagemagick to version 8:6.9.9.34+dfsg-3 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:unstable 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.
