NFS: Short Read
This protocol anomaly triggers when it detects an NFS packet that does not contain enough UDP data.
Extended Description
If an NFS RPC datagram fails to include the standard fields required by the RPC specifications, or contains a REPLY without an associated CALL, this constitutes a protocol anomaly, which could indicate a network configuration error. It could also indicate that a malicious party is attempting an attack via injection of malformed RPC/NFS datagrams into the affected network.
