CVE-2026-49218

A flaw was found in ImageMagick. A missing check in the DCM (Digital Imaging and Communications in Medicine) decoder allows a remote attacker to provide a specially crafted image with invalid dimensions. This can lead to crashes in other operations, resulting in a denial of service (DoS) for the application processing the image.

It is important to note that ImageMagick has been removed from Red Hat Enterprise Linux 8 and later releases. Therefore, current supported RHEL 8 and newer systems are not affected by this issue unless ImageMagick is installed from third-party or custom repositories.
