Name of the Vulnerable Software and Affected Versions Pacemaker versions up to and including 2.0.1

Description The issue is related to an uncontrolled resource consumption in the Pacemaker cluster resource management software, which can be exploited to cause a denial of service (DoS). This could allow an attacker to disrupt service operations. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited.
