Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In ImageMagick 7.0.7-12 Q16, a memory leak vulnerability was found in the function ReadMATImage in coders/mat.c, which allows attackers to cause a denial of service via a crafted MAT image file.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A memory leak exists in ImageMagick 7.0.7-12 Q16 within the ReadMATImage function in coders/mat.c. When processing a crafted MAT (MATLAB) image file, memory is allocated during parsing but not properly freed, leading to memory exhaustion and denial of service.

MitigationUpdate ImageMagick to a version beyond 7.0.7-12 that contains the patch, or disable MAT file format support in ImageMagick if MAT files are not required for processing.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed ImageMagick version
    Run 'convert -version' or 'identify -version' and look for the version number in the output
    Affected if The version shown is exactly 7.0.7-12
  2. Verify MAT coder module availability
    Run 'identify -list configure' and look for 'DELEGATES' or 'CODERS' sections, or check if 'mat' appears in the list of supported formats with 'identify -list format'
    Affected if MAT format is listed as a supported format or the mat coder is present
  3. Confirm MAT file processing capability
    Run 'identify /path/to/any.mat' on a sample MAT file, or check if ImageMagick can identify MAT files at all
    Affected if ImageMagick can read and identify MAT file format without error, indicating the vulnerable coder is active

You are affected if ImageMagick version 7.0.7-12 is installed AND the MAT file format coder (coders/mat.c) is enabled and capable of processing MAT files in your environment.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update ImageMagick to a version beyond 7.0.7-12 that contains the patch, or disable MAT file format support in ImageMagick if MAT files are not required for processing.
