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
Integer overflow in GameMaker IDE below 2024.14.0 version can lead to can lead to application crashes through denial-of-service attacks (DoS). GameMaker users who use the network_create_server() function in their projects  are urged to update and recompile immediately.

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 · moderate confidence

Integer overflow vulnerability in GameMaker IDE's network_create_server() function in versions prior to 2024.14.0 allows attackers to trigger application crashes via crafted input, causing denial of service.

MitigationUpdate GameMaker IDE to version 2024.14.0 or later and recompile all projects that utilize the network_create_server() 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 GameMaker IDE version
    Open GameMaker IDE and navigate to Help > About, or check the installation directory for version information. The version number is typically displayed in the main window title bar or in the IDE preferences.
    Affected if The installed GameMaker IDE version is earlier than 2024.14.0 (e.g., 2024.13.0, 2024.12.0, or earlier)
  2. Identify projects using network_create_server()
    Search project source files (typically .gml files in the datafiles folder or included in the project) for the string 'network_create_server' using a text search or the IDE's built-in search function.
    Affected if The project contains code that calls the network_create_server() function and the function is actually used/executed at runtime

If GameMaker IDE version is below 2024.14.0 AND the project executes network_create_server(), the environment is vulnerable to integer overflow causing potential denial of service.
