This addresses the client_login() Icecast issue:
For those who have a burning need to 'patch < patch', or just don't
want to type three lines into client.c, I've attached a small
patch to client.c (Icecast 1.3.11).
Simplicity is thy name.
(More specific: It's the suggested patch in the icx.c exploit, with
an added logging flag.)
Thanks to Diz for making this public.
