heartbeat.c in heartbeat before 2.0.6 sets insecure permissions in a shmget call for shared memory, which allows local users to cause an unspecified denial of service via unknown vectors, possibly during a short time window on startup.

Security readout for executives and security teams

This is an old local denial-of-service flaw in Linux-HA Heartbeat before 2.0.6. During startup, Heartbeat created shared memory with insecure permissions, which could let a local user disrupt service. The main business concern is availability of legacy high-availability clusters, not remote compromise. Exposure is most likely on legacy Linux systems still running Linux-HA Heartbeat before 2.0.6 or vendor builds lacking the 2006 security update. Internet-facing exposure is not indicated; local user access appears required. Treat this as a legacy availability risk. It is not presented as remotely exploitable, but vulnerable HA infrastructure can undermine resilience. Prioritize if Heartbeat still protects business-critical services or shared multi-user systems. Mitigation focus: Upgrade Heartbeat to 2.0.6 or a vendor-patched package.; Check Debian, Gentoo, Ubuntu, and Mandriva advisories for fixed package guidance.; Limit local shell access on cluster nodes to trusted administrators..
