Comment (by essandess):

 The ImageMagick binaries distributed by MacPorts have several critical
 CVEs. This port must be updated to latest ASAP.

 I’ve posted PR https://github.com/macports/macports-ports/pull/16945 that
 does this and builds the latest without the deprecated OpenCL stuff, with
 OpenMP, and other minor changes.
