Linux-HA Heartbeat Insecure Default Permissions on Shared Memory Vulnerability

Since Linux-HA Heartbeat has insecure default permissions set on shared memory, local attackers may be able to cause a denial of service.

Exploitation would most likely result in a system crash, loss of data, and resource exhaustion, leading to a denial of service if critical files are accessed improperly or overwritten in the attack. Other attacks may be possible as well.
