Mitigation Strategies

The primary mitigation step is to upgrade ImageMagick to version 7.1.2-15 or later, or 6.9.13-40 or later, where this vulnerability has been patched.

Until the upgrade is applied, avoid processing untrusted or specially crafted MAP image files with vulnerable versions of ImageMagick.

Executive Summary

[{'type': 'paragraph', 'content': "CVE-2026-25987 is a moderate severity vulnerability in ImageMagick's MAP image decoder. It is a heap buffer over-read issue that occurs when processing specially crafted MAP files. This means the decoder reads beyond the allocated memory buffer, which can cause the application to crash or unintentionally disclose parts of memory during image decoding."}] [1]

Detection Guidance

This vulnerability occurs when ImageMagick processes specially crafted MAP files, causing heap buffer over-reads that may lead to crashes or memory disclosure.

To detect exploitation attempts on your system or network, monitor for crashes or abnormal behavior in ImageMagick processes, especially when handling MAP image files.

You can also scan files for suspicious or malformed MAP images before processing.

Specific commands to detect this vulnerability are not provided in the available resources.
