daemon.c in cman (redhat-cluster-suite) before 20070622 does not clear a buffer for reading requests, which might allow local users to obtain sensitive information from previous requests.

possible buffer overflow could cause local DoS by crashing cman

Buffer overflow in cluster/cman/daemon/daemon.c in cman (redhat-cluster-suite) before 20070622 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via long client messages.

lvm2-cluster: insecurity when communicating between lvm2 and clvmd

The cluster logical volume manager daemon (clvmd) in lvm2-cluster in LVM2 before 2.02.72, as used in Red Hat Global File System (GFS) and other products, does not verify client credentials upon a socket connection, which allows local users to cause a denial of service (daemon exit or logical-volume change) or possibly have unspecified other impact via crafted control commands.
