Details follow: Multiple insecure temporary file handling vulnerabilities were discovered in Red Hat Cluster. A local attacker could exploit these to overwrite arbitrary local files via symlinks. (CVE-2008-4192, CVE-2008-4579, CVE-2008-4580, CVE-2008-6552) It was discovered that CMAN did not properly handle malformed configuration files. An attacker could cause a denial of service (via CPU consumption and memory corruption) in a node if the attacker were able to modify the cluster configuration for the node. (CVE-2008-6560)
