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 7.0.5-5, a memory leak was found in the function ReadPSDChannel in coders/psd.c, which allows attackers to cause a denial of service via a crafted 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

ImageMagick 7.0.5-5 contains a memory leak in the ReadPSDChannel function within coders/psd.c when parsing Photoshop Document (PSD) files. Attackers can trigger the leak by supplying a specially crafted PSD file, causing memory allocation without corresponding deallocation. Repeated exploitation leads to memory exhaustion and denial of service.

MitigationUpdate ImageMagick to the latest version which includes the patch for this vulnerability. Alternatively, disable or restrict PSD file processing via ImageMagick's delegate policies or security configuration if immediate patching is not feasible.

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 note the version string
    Affected if The version shown is exactly 7.0.5-5
  2. Verify PSD delegate support
    Run 'convert -list configure | grep DELEGATES' or check if PSD files can be identified with 'identify -verbose sample.psd'
    Affected if PSDs are listed as supported or ImageMagick can read a PSD file without error
  3. Check for PSD policy restrictions
    Look for a policy.xml file (commonly at /etc/ImageMagick-6/policy.xml or /etc/ImageMagick/policy.xml) and check for entries restricting PSD read rights
    Affected if No policy entry exists that blocks or restricts PSD file reading, meaning PSD processing is allowed

You are affected if ImageMagick version is exactly 7.0.5-5 and PSD file processing is enabled without policy restrictions blocking it.
