How to fix?

Upgrade Debian:9 imagemagick to version 8:6.9.7.4+dfsg-11+deb9u12 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.

A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of a too large shift for 64-bit type ssize_t. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
