The version of nfs-server that was distributed in Debian GNU/Linux 2.1 had a
buffer overflow in fh_buildpath(). It assumed that the total length of a path
would never exceed (PATH_MAX_NAME_MAX). With a read/write exported directory
people could created longes path and cause a bufferoverflow.

This has been addressed in version 2.2beta37-1slink.1, and we recommend you
upgrade your nfs-server package immediately.
