Problem  : Multiple remote buffer overflows



--- Intro ---

Netstd is a package of networking utilities and daemons
from the Debian Linux distribution.

--- Problem ---

It is possible to remotely overflow buffers in several utilities
from the package, through owned DNS server.
The FQDN obtained from the reply is simply copied into small fixed
size buffer, without any check on the length of the answer.

The same problem is present in these utils from the netstd 3.07-17
package:

- linux-ftpd
- pcnfsd
- tftp
- traceroute
- from/to
