CVE-2018-4053
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 exploitable local denial-of-service vulnerability exists in the privileged helper tool of GOG Galaxy's Games, version 1.2.47 for macOS. An attacker can send malicious data to the root-listening service, causing the application to terminate and become unavailable.
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.

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 GOG Galaxy is installedCheck for GOG Galaxy application in /Applications folder or use 'ls /Applications' to list installed applications and look for 'GOG Galaxy' or 'GOG Galaxy Games'Affected if GOG Galaxy appears in installed applications
-
Identify installed GOG Galaxy versionRight-click GOG Galaxy.app > Get Info, or use command: 'defaults read /Applications/GOG\ Galaxy.app/Contents/Info CFBundleShortVersionString' (adjust path if app name differs)Affected if Version displayed is exactly 1.2.47
-
Check if privileged helper tool is installedLook for the helper tool at /Library/PrivilegedHelperTools/com.gog.galaxyservice or check via LaunchDaemon: 'ls /Library/LaunchDaemons/' for com.gog.galaxyservice.plistAffected if Privileged helper tool daemon is present in the system
-
Confirm helper tool is activeCheck if the LaunchDaemon is running: 'sudo launchctl list | grep -i gog' or 'ps aux | grep -i galaxyservice'Affected if The helper tool service is loaded and running
User is affected only if GOG Galaxy version 1.2.47 is installed AND the privileged helper tool (com.gog.galaxyservice) is present and active on the system

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 to a patched version of GOG Galaxy's Games. Until then, restrict local access to the system and monitor for unauthorized helper tool communication attempts.
