thanks for the report, no I am not on bugtraq, I rely on
people in there contacting us to forward what's relevant ;)
As reported I don't think this problem exists on undernet's
codebase, since version .02 or such the reply of ident is
strongly checked and allows a very restricted set of chars,
dropping off (either by replacing them with _ or by forcing
them to terminate the userid) basically any non plain ascii
char and any char that has a special meaning to the irc
protocol.
Should something have slipped out of the checks.. jst report
it to me and will be fixed on the fly, as of now I think that
Undernet's ircu is safe from this kind of exploit.

[P.S.: Why there are on bugtraq 50 persons unable to tell their
"vacation" message to not be sent to the posters of the mailing
lists ? Lameness....]
