To mitigate the threat of unpatched license manager installations, exposing or offering the license manager service to the Internet is prohibited. Also, since it is up to each software publisher to integrate the patches into their applications and products, FNAL Computer Security cannot set a patch-by date. Since the software publishers can define their own port number for license manager use, FNAL Computer Security cannot easily implement a border block. In addition, apply one or more of the Host Remediations listed at the top of this notice. Please contact your software publisher or application vendor for updates to your applications.

Multiple vulnerabilities have been announced for the FlexNet License Server (FlexLM), a license manager used in many products such as Matlab, TeamCenter and other Engineering/CAD software. Local firewalls or other access controls must be implemented locally to prevent exposure of the license manager service outside of the FNAL network Both daemons run on the license server, but function differently. For floating licenses, two FLEXlm daemons work in conjunction: the FLEXlm license manager daemon ( lmgrd) and at least one vendor daemon. For comprehensive details, refer to the FLEXlm End User Manual. Host Remediation: Upgrade FlexNet License Server configure local firewall to prevent license server access to/from specific nodes run the license server as an unprivileged user migrate the local license manager to the central license manager serverįNAL Site Actions: FlexNet/FlexLM installations cannot offer the license services to the Internet.
