FreeBSD Security Advisory FreeBSD-SA-06:10.nfs - A part of the NFS server code charged with handling incoming RPC messages via TCP had an error which, when the server received a message with a zero-length payload, would cause a NULL pointer dereference which results in a kernel panic. The kernel will only process the RPC messages if a userland nfsd daemon is running.
