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
Buffer overflow in NetMeeting allows denial of service and remote command execution.

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

A buffer overflow vulnerability in Microsoft NetMeeting, a legacy video conferencing application, allows remote attackers to cause denial of service or potentially execute arbitrary code via crafted network requests.

MitigationSince NetMeeting is deprecated and no longer receives security updates, organizations should uninstall or disable the application immediately. Network-based controls like firewalls and segmentation can provide additional protection where removal isn't feasible.

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 if NetMeeting is installed
    Navigate to Control Panel > Programs and Features, or check for the presence of NetMeeting executable files (nm.exe or conf.exe) in system directories such as C:\Program Files\NetMeeting or C:\Windows\System32
    Affected if NetMeeting application is found installed on the system
  2. Identify the installed version
    Right-click on the NetMeeting executable (nm.exe) and select Properties, then check the Details tab for version information, or launch NetMeeting and go to Help > About
    Affected if The installed version is exactly 2.1
  3. Verify if NetMeeting process is running
    Open Task Manager and look for nm.exe or conf.exe processes, or run 'tasklist /FI "IMAGENAME eq nm.exe"' from command prompt
    Affected if NetMeeting process is actively running on the system
  4. Confirm if remote access is enabled
    Check NetMeeting settings under Tools > Options > General tab for 'Enable remote desktop sharing' or 'Accept calls', or examine Windows Firewall rules for exceptions related to NetMeeting (ports 1503, 389, 522, 1720)
    Affected if NetMeeting is configured to accept incoming network requests or calls

The system is affected if Microsoft NetMeeting version 2.1 is installed and configured to accept remote connections, as the buffer overflow can be exploited via crafted network requests to this service.
