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
Inappropriate implementation in Skia canvas composite operations in Google Chrome prior to 63.0.3239.84 allowed a remote attacker to leak cross-origin data via a crafted HTML page.

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

Skia canvas composite operations in Chrome had an inappropriate implementation that allowed a crafted HTML page to leak cross-origin data by exploiting how the canvas composite operations handled images from different origins, enabling pixel data extraction that should be blocked by the same-origin policy.

MitigationUpdate Google Chrome to version 63.0.3239.84 or later to patch the Skia library vulnerability.

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. Verify Chrome or Chromium browser is installed
    Check for browser executable: run 'google-chrome --version' or 'chromium --version' or look for Chrome in installed programs
    Affected if No Chrome/Chromium browser is found on the system, then this CVE does not apply
  2. Determine the exact Chrome version
    Run 'google-chrome --version' to get the installed version number (e.g., 63.0.3239.83)
    Affected if Version number is lower than 63.0.3239.84 (e.g., 63.0.3239.83 or earlier)
  3. Confirm Chromium-based browser version if Chrome is not present
    Run 'chromium --version' or check package manager for chromium-browser package version
    Affected if Chromium version is lower than 63.0.3239.84 or version is unknown and browser is present

You are affected if Chrome or Chromium browser is installed with a version lower than 63.0.3239.84, as the vulnerability exists in the Skia library's canvas composite operations for those versions.
