CVE-2026-116144

A flaw was found in ImageMagick. An attacker could cause a Denial of Service (DoS) by supplying a specially crafted Magick Vector Graphics (MVG) file. When processed, the file triggers uncontrolled recursion within the MVG decoder, exhausting stack memory and causing the application to crash.

This vulnerability is evaluated as Low severity because exploitation requires processing an untrusted Magick Vector Graphics file, resulting solely in an application crash without compromising system confidentiality or integrity. In standard Red Hat Enterprise Linux environments, ImageMagick operates as a utility for batch conversions or localized document processing rather than an exposed privileged daemon. The blast radius is therefore confined to the specific process instance executing the conversion, and system stability is recovered immediately upon process exit.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Disable decoding of Magick Vector Graphics files by configuring the ImageMagick security policy.

Add the following directive inside the <policymap> section in /etc/ImageMagick/policy.xml (or /etc/ImageMagick-6/policy.xml):

<policy domain="coder" rights="none" pattern="MVG" />

Caveats: Applications and workflows requiring MVG format processing will fail to render these files. If ImageMagick is utilized by background daemons or web servers (such as httpd or php-fpm), restart those services to ensure the policy takes effect.
