SGI Security Advisory 20030801-01-P – It is possible to create a Denial of Service attack on the IRIX nfsd through the use of carefully crafted packets which cause XDR decoding errors. This can lead to kernel panicing the system. No local account or access to an NFS mount point is required, so this could be constructed as a remote exploit.
