imagemagick imagemagick UPGRADE

Affected: < 6.9.13-51 · >= 7.0.0-0 and < 7.1.2-26

Fixed in: 6.9.13-51, 7.1.2-26

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 6.9.13-51 (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.
