"The version of Flexera FlexNet Publisher running on the remote host is
prior to 11.16.2. It is, therefore, 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)");
