Well spotted. It's already been independently spotted by both myself and
Jeff Uphoff. The nfs-utils case will be fixed by Jeff I hope.

More seriously, perhaps.... an identical flaw exists in glibc rpcgen. I've
informed the glibc maintainers, and it'll get fixed. I wonder what glibc
rpcgen is used to generate code for. Internal bits of glibc rpc
code? (ouch). Vulnerabilities in portmap? mountd?

Comments requested..
