No, it is still vulnerable.  I have confirmed for myself that the fix
applied in the DSA did not eliminate the DoS.  The only way to be safe
right now is to add the following to /etc/proftpd.conf:
<Global>
  DenyFilter                    \*.*/
</Global>

The problem is not likely with proftpd, but with glibc.  I am going to
begin investigating fixes ASAP.
