Routine

MEDIUM 5.3REMOTEUPGRADE

CVE-2026-45664 is a medium-severity flaw (CVSS 5.3) affecting imagemagick. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, because of a missing check in the MNG coder it would be possible to read more images than the list limit policy would allow resulting in excessive resource use. This issue has been patched in versions 6.9.13-47 and 7.1.2-22.

imagemagick imagemagick UPGRADE

Affected: < 6.9.13-47 · >= 7.0.0-0 and < 7.1.2-22

Fixed in: 6.9.13-47, 7.1.2-22

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 6.9.13-47 (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.
