To me, ImageMagick is lagging behind since a long while and we need to
upgrade to the latest version ASAP. Unfortunately we don't seem to be
able to do that since it has lots of dependents and backporting each
and every of these patches is just impossible, also there's way more in
the commit history without security labeling like CVE.

I don't want to deal with backporting things for ImageMagick to catch
up with the previous security fixes that no one cared to apply in due
time earlier. It's just too much.
