Sun Cluster 2.2 through 3.2 for Oracle Parallel Server / Real Application Clusters (OPS/RAC) allows local users to cause a denial of service (cluster node panic or abort) by launching a daemon listening on a TCP port that would otherwise be used by the Distributed Lock Manager (DLM), possibly involving this daemon responding in a manner that spoofs a cluster reconfiguration.

The clustmon service in Sun Cluster 2.x does not require authentication, which allows remote attackers to obtain sensitive information such as system logs and cluster configurations.

Unspecified vulnerability in Sun Cluster 3.1 and Solaris Cluster 3.2 before 20070424 allows remote authenticated users, operating from a different cluster node, to cause a denial of service (data corruption or sendmondo panic) via unspecified vectors, as demonstrated by EMC Symcli backup software 6.2.1.
