CVE-2017-5048
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 · uneditedAn integer overflow in FFmpeg in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android allowed a remote attacker to perform an out of bounds memory write via a crafted video file, related to ChunkDemuxer.
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 confidenceAn integer overflow vulnerability exists in FFmpeg's ChunkDemuxer component within Google Chrome versions prior to 57.0.2987.98 (Mac/Windows/Linux) and 57.0.2987.108 (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 checksWork through these to decide whether this CVE applies to you.
-
Verify Google Chrome is installedCheck for Chrome installation by looking for chrome.exe on Windows, Google Chrome.app on macOS, or google-chrome on Linux. On Android, check for Chrome in /data/data/ or via package manager.Affected if Google Chrome is present on the system
-
Determine the installed Chrome versionOpen Chrome and navigate to chrome://version, or run 'google-chrome --version' on Linux/macOS, or check the APK version on Android.Affected if The displayed version is 57.0.2987.75 or earlier on desktop (Mac/Windows/Linux), or 57.0.2987.100 or earlier on Android
-
Confirm ChunkDemuxer usage contextThe ChunkDemuxer component handles certain media formats. The vulnerability triggers when Chrome processes crafted video files that use this demuxer. No special configuration check is needed as this is a built-in component.Affected if The affected Chrome version processes media files (particularly formats handled by ChunkDemuxer)
You are affected if Google Chrome is installed with version 57.0.2987.75 or earlier on desktop platforms, or 57.0.2987.100 or earlier on Android, and the browser processes video files.

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 dataUpdate Google Chrome to version 57.0.2987.98 or later for desktop platforms, or 57.0.2987.108 or later for Android. For enterprise environments, deploy the update via group policy or MDM solutions and verify completion across all endpoints.
