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.
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.
