CVE-2018-20034: A Denial of Service vulnerability related to adding an item to a list in lmgrd and vendor daemon components...

Security readout for executives and security teams

CVE-2018-20034 can let a remote attacker disrupt FlexNet Publisher license services. If affected lmgrd or vendor daemon components are reachable, the vendor daemon may shut down, which can interrupt licensed software availability and business operations that depend on it. Exposure is most likely where FlexNet Publisher lmgrd or vendor daemon services version 11.16.1.0 or earlier are reachable from untrusted networks. Risk is operational rather than data-theft focused, but license outages can affect engineering, enterprise applications, or vendor-managed software. Treat this as a business continuity risk. Prioritize systems where license service downtime would stop revenue, operations, engineering, or customer-facing services, especially if reachable beyond trusted internal networks. Mitigation focus: Identify all FlexNet Publisher lmgrd and vendor daemon deployments.; Check Flexera advisory 85979 for vendor-approved fixed versions or mitigations.; Restrict license service access to trusted networks and required clients..
