Due to a fwtk-users listserver outage, I could not post my results. 
Therefore, I am posting them here.

After several days of testing, I can say that the unmodified FWTK 2.1
smap process is *NOT* vulnerable to the same overflow as Gauntlet. I 
will be testing 2.1 smap+Joe Yao's patch next.

Also, for those of you who asked me, the NAI notice is correct; Gauntlet 
4.2 does not seem to be vulnerable to the buffer overflow.
