Esri encourages ALL users to upgrade to ArcGIS License Manager 2019.0 to address these security concerns in Flexera FlexNet Publishers. 

This update – ArcGIS License Manager 2019.0 - addresses several vulnerabilities in Flexera FlexNet Publisher that are exploitable prior to FlexNet Publisher 11.16.2.  ArcGIS License Manager 2019.0 uses FLEXnet Publisher 11.16.2.1. 

Versions of Flexera FlextNet Publisher prior to 11.16.2 are affected by multiple vulnerabilities: 

• A Denial of Service vulnerability related to preemptive item deletion in lmgrd and vendor daemon components of FlexNet Publisher version 11.16.1.0 and earlier allows a remote attacker to send a combination of messages to lmgrd or the vendor daemon, causing the heartbeat between lmgrd and the vendor daemon to stop, and the vendor daemon to shut down. (CVE-2018-20031)
• A Denial of Service vulnerability related to message decoding in lmgrd and vendor daemon components of FlexNet Publisher version 11.16.1.0 and earlier allows a remote attacker to send a combination of messages to lmgrd or the vendor daemon, causing the heartbeat between lmgrd and the vendor daemon to stop, and the vendor daemon to shut down. (CVE-2018-20032)
• A Remote Code Execution vulnerability in lmgrd and vendor daemon components of FlexNet Publisher version 11.16.1.0 and earlier could allow a remote attacker to corrupt the memory by allocating / deallocating memory, loading lmgrd or the vendor daemon and causing the heartbeat between lmgrd and the vendor daemon to stop. This would force the vendor daemon to shut down. (CVE-2018-20033)
• A Denial of Service vulnerability related to adding an item to a list in lmgrd and vendor daemon components of FlexNet Publisher version 11.16.1.0 and earlier allows a remote attacker to send a combination of messages to lmgrd or the vendor daemon, causing the heartbeat between lmgrd and the vendor daemon to stop, and the vendor daemon to shut down. (CVE-2018-20034)
