This is only a small one and not that serious because remote lusers shouldnt
have access to your portmappers at all. However if they do then rpc.mountd
gives out more info than is ideal.
Viz
mount testbox:/usr/lib /mnt
mount testbox:/usr/lib failed, reason given by server: Permission denied
mount testbox:/usr/libs /mnt
mount: testbox:/usr/libs failed, reason given by server: No such file or directory
ie you can use it to test what is installed on a box.
