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
A Denial of Service vulnerability related to command handling has been identified in FlexNet Publisher lmadmin.exe version 11.16.2. The message reading function used in lmadmin.exe can, given a certain message, call itself again and then wait for a further message. With a particular flag set in the original message, but no second message received, the function eventually return an unexpected value which leads to an exception being thrown. The end result can be process termination.

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

A denial of service vulnerability exists in FlexNet Publisher's lmadmin.exe version 11.16.2. The message reading function can recursively call itself when processing a specific message type. When a particular flag is set in the original message without a follow-up message being received, the function returns an unexpected value, triggering an exception that terminates the process.

MitigationApply the vendor-supplied patch or upgrade to a patched version of FlexNet Publisher. If a patch is unavailable, restrict network access to the lmadmin service and implement process monitoring to detect and restart terminated instances.

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. Locate the lmadmin.exe process
    Open Task Manager or run 'tasklist /FI "IMAGENAME eq lmadmin.exe"' in Command Prompt
    Affected if lmadmin.exe is running on the system
  2. Check lmadmin.exe version
    Right-click lmadmin.exe in Task Manager > Properties, or use 'wmic process where name="lmadmin.exe" get version'
    Affected if Version shows 11.16.2 exactly
  3. Verify the full version string
    Check the File Version field in the lmadmin.exe properties window, or inspect the binary's version info resource
    Affected if File version is exactly 11.16.2 (build 274051)
  4. Confirm lmadmin network listening status
    Run 'netstat -an | findstr LISTENING' and look for ports 27000-27009 or 2700-2709 typically used by FlexNet, or use 'netsh advfirewall firewall show rule name=all' to check firewall rules for lmadmin
    Affected if The lmadmin service is listening on network ports and accessible to untrusted networks

The system is affected if lmadmin.exe version 11.16.2 is running and the license manager service is exposed to network traffic, allowing remote attackers to send the triggering message that causes the DoS.
