IESG NOTE:

The IRC protocol itself enables several possibilities of transferring

data between clients, and just like with other transfer mechanisms

like email, the receiver of the data has to be careful about how the

data is handled. For more information on security issues with the IRC

protocol, see for example http://www.irchelp.org/irchelp/security/.
