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.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
