The last upload of redhat cluster fix several bugs, among them the tmpflie
issues from #496410, among them CVE-2008-4192 and CVE-2008-4579 and many
others discovered and fixed by upstream during a code audit.
I know this is a new upstream release, but if you check the changelog
(attached), it contains mostly bug fixes, among them really important ones
like the noatime fix (which you really want on a shared FS, to avoid
exclusive read locks on the inodes every time a file is accessed).
