The lvm2-cluster updates RHSA-2010:0567 and RHSA-2010:0568 changed the cluster logical volume manager daemon (clvmd) to use a pathname-based socket, rather than an abstract socket. This update changes LVM to also use this pathname-based socket, allowing LVM to be able to communicate with the updated clvmd. See [1] https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2010-2526 for further details.
