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 7.0.7-16 Q16 x86_64 2017-12-21, there is a stack-based buffer over-read in WriteWEBPImage in coders/webp.c, related to a WEBP_DECODER_ABI_VERSION check.

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 stack-based buffer over-read vulnerability exists in ImageMagick 7.0.7-16 Q16 in the WriteWEBPImage function within coders/webp.c. The flaw is triggered during WebP image encoding and relates to an improper WEBP_DECODER_ABI_VERSION check, potentially allowing attackers to read sensitive stack memory contents.

MitigationUpdate ImageMagick to a version newer than 7.0.7-16 that includes the fix for this vulnerability, or apply the vendor-supplied patch to coders/webp.c to correct the buffer handling logic in the WriteWEBPImage function.

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 `identify -version` or `convert -version` to retrieve the installed ImageMagick version
    Affected if The version displayed is exactly 7.0.7-16 (any other version is not affected by this specific CVE)
  2. Verify WebP encoding support is present
    Run `identify -list format | grep -i webp` or `convert -list configure | grep -i webp` to confirm WebP support is compiled into the ImageMagick installation
    Affected if WebP format support appears in the list, indicating the vulnerable coders/webp.c module is loaded/enabled
  3. Confirm WebP encoding capability exists
    Attempt `convert input.png webp:output.webp` with any test image to verify encoding to WebP format is possible
    Affected if WebP encoding completes without error, meaning the WriteWEBPImage function is operational and could trigger the vulnerability

You are affected only if your ImageMagick version is exactly 7.0.7-16 AND WebP encoding support is enabled in your installation.
