There has been an update: 2.6.17-10.33 ---> 2.6.17.1-10.34 Anybody knows if that update it's supposed to solve this? or it's unrelated?
I only see this talking about nfs in the release-info (http://www.ubuntu.com/usn/usn-395-1) and I dunno if it's worth a try or not: Matthias Andree discovered that the NFS locking management daemon (lockd) did not correctly handle mixing of 'lock' and 'nolock' option mounts on the same client. A remote attacker could exploit this to crash lockd and thus rendering the NFS imports inaccessible. This only affects Ubuntu 5.10.
