Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Versions 14.10.1 and below have a NULL pointer dereference vulnerability in the MSL (Magick Scripting Language) parser when processing <comment> tags before images are loaded. This can lead to DoS attack due to assertion failure (debug builds) or NULL pointer dereference (release builds). This issue is fixed in version 14.10.2.

AI Analysis

Impact

ImageMagick, a widely used open‑source image manipulation library, contains a NULL pointer dereference flaw in the Magick Scripting Language parser. The issue is triggered when a <comment> tag is parsed before an image is loaded, causing an assertion failure in debug builds or a NULL dereference in release builds. The resulting crash can interrupt services that rely on ImageMagick or its .NET bindings, effectively creating a denial‑of‑service vulnerability. The weakness is classified as CWE‑476 (NULL Pointer Dereference).

Affected Systems

Affected products include the ImageMagick software itself and the Magick.NET .NET wrapper. Versions 14.10.1 and earlier are vulnerable; the flaw is addressed in ImageMagick 14.10.2 and the corresponding Magick.NET 14.10.2 release. No other products or versions are identified in the current advisory.

Risk and Exploitability

The vulnerability received a CVSS score of 6.5, indicating moderate severity, while the EPSS score is below 1 %, pointing to a low exploitation probability. It is not listed in the CISA KEV catalog. Based on the description, it is inferred that the attacker would need to supply a crafted image file that contains a <comment> tag before the image data. This typically implies a local or privileged context unless the target application allows remote image uploads. Given the current metrics, the risk is moderate but still warrants timely mitigation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade ImageMagick to version 14.10.2 or later.
  • Upgrade the Magick.NET .NET wrapper to version 14.10.2 or later.
  • If an upgrade is not immediately possible, sanitise incoming image files to remove or escape <comment> tags before processing with ImageMagick.
