A DoS vulnerability in FlexNet Publisher <=11.16.1.0 allows remote attackers to stop heartbeat between lmgrd and vendor daemon, causing shutdown.
Vulnerability
The vulnerability exists in the message decoding functionality of the lmgrd and vendor daemon components in FlexNet Publisher version 11.16.1.0 and earlier [1]. An attacker can send a crafted combination of messages to trigger the condition.
Exploitation
A remote attacker with network access to the lmgrd or vendor daemon can send a specific combination of messages, causing the heartbeat mechanism between lmgrd and the vendor daemon to stop, leading to the shutdown of the vendor daemon.
Impact
Successful exploitation results in a denial of service by shutting down the vendor daemon, disrupting the license management service.
Mitigation
As of the initial publication, a fix is not explicitly detailed in the available reference [1]. Users should upgrade to a version beyond 11.16.1.0 if available, or consult Flexera for a patch.
