Timeline

imagemagick imagemagick UPGRADE
Affected: < 6.9.13-48 · >= 7.0.0-0 and < 7.1.2-24
Fixed in: 6.9.13-48, 7.1.2-24
Safe to downgrade to: a release before 7.0.0-0
1. Check installed version
apt-cache policy imagemagick || rpm -q imagemagick || imagemagick --version
2. UPGRADE to 6.9.13-48 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade imagemagick
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade imagemagick
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 7.0.0-0 (Debian / Ubuntu)
apt-cache madison imagemagick sudo apt install imagemagick=<VERSION_BEFORE_7.0.0-0> sudo apt-mark hold imagemagick
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list imagemagick sudo dnf downgrade imagemagick-<VERSION_BEFORE_7.0.0-0> sudo dnf versionlock add imagemagick
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
