join bug

Hello, I discovered a way to make the "join" command crash shells and
make them completely non usable.  This can be used to make a small
program and create a virus like situation.  If this program ran in
console <no other virtual terminals> then it will make the local
terminal completely worthless and only a reboot will fix the problem.  I
have not tried it as root yet but I think it should have the same
effects.  What do I do now?  How do I report this and to whom?  Finally
if you do think that this is an important discovery that needs an
update, will you give me the credit ( mention my name) for bringing this
up :)? Note: this method has been tested on "join" versin 2.0 on a Linux
machine running kernel 2.2.17ยท
