Security readout for executives and security teams
CVE-2018-16878 affects ClusterLabs Pacemaker through version 2.0.1. A local attacker or uncontrolled local process could trigger a denial of service, potentially disrupting cluster availability. This is mainly a resiliency risk for systems that rely on Pacemaker for high-availability failover. Exposure is most likely on Linux high-availability clusters running Pacemaker up to and including 2.0.1. Risk is higher where untrusted users, jobs, or applications can execute locally on cluster nodes. Treat this as a scheduled but important availability fix. It is not described as remotely exploitable or actively exploited, but affected Pacemaker clusters may support critical service continuity, so downtime impact can be business-significant. Mitigation focus: Inventory Pacemaker versions across all cluster nodes.; Apply vendor Pacemaker security updates from the relevant distribution advisory.; Check ClusterLabs and operating-system vendor guidance for fixed package versions..
