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
An off by one error resulting in an allocation of zero size in FFmpeg in Google Chrome prior to 54.0.2840.98 for Mac, and 54.0.2840.99 for Windows, and 54.0.2840.100 for Linux, and 55.0.2883.84 for Android allowed a remote attacker to potentially exploit heap corruption via a crafted video 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

An off-by-one error in the FFmpeg library bundled with Google Chrome causes a zero-size memory allocation, leading to heap corruption when processing specially crafted video files. This remote code execution vulnerability is triggered when a user opens a malicious video file in Chrome.

MitigationUpdate Google Chrome to version 54.0.2840.98 or later for Mac, 54.0.2840.99 or later for Windows, 54.0.2840.100 or later for Linux, or 55.0.2883.84 or later for Android.

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 Chrome version
    Navigate to chrome://settings/help or use 'Chrome --version' from command line to see the current browser version
    Affected if Version number is 54.0.2840.87 or lower
  2. Identify Chrome platform
    Determine if Chrome is running on Windows, Mac, Linux, or Android by checking the operating system
    Affected if Running any platform with Chrome version <= 54.0.2840.87
  3. Assess video processing usage
    Determine if the browser is used to open or process video files, which is the attack vector for this vulnerability
    Affected if User opens untrusted video files in Chrome

User is affected if Chrome version is 54.0.2840.87 or lower AND the browser is used to open or process video files
