lvm2-cluster (clvmd) security fix (Moderate)

I have released version 2.02.72 of LVM2 today to address a security problem.

If you are running clvmd on a machine where you also have non-root users
you should seriously consider applying the patch, The problem has been
in the code base since 2004. LVM2 on its own is not vulnerable to this problem.

Vendors were notified last week.

Red Hat's Security Advisories are here:

Fuller details are in the Red Hat Bugzilla:
https://bugzilla.redhat.com/CVE-2010-2526

The essential part of the patch is attached there and it should apply to older releases too.
