buffer overflow in nslookup?

[peter () ATTIC VUURWERK NL (Peter van Dijk)]

[peter@koek] ~$ nslookup `perl -e 'print "A" x 100;'`

*** zopie.attic.vuurwerk.nl can't find AAA.....AAA: Unspecified error

At first, this does not seem a problem: nslookup is not suid root or anything.
But several sites have cgi-scripts that call nslookup... tests show that these
will coredump when passed enough characters. Looks exploitable to me...

Greetz, Peter.
