CVE-2019-13574 (opens in a new tab)How to fix?
Upgrade Debian:11 ruby-mini-magick to version 4.9.2-1.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby-mini-magick package and not the ruby-mini-magick package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
In lib/mini_magick/image.rb in MiniMagick before 4.9.4, a fetched remote image filename could cause remote command execution because Image.open input is directly passed to Kernel#open, which accepts a '|' character followed by a command.
