Overview

Affected versions of this package are vulnerable to Buffer Overflow. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. The NFSD is not expecting the oversized request and writes beyond the allocated buffer space.
