the environment of the client site. The information can be used as
preparation for further attacks. This bug can also be exploited by
using the telnet:// URL on a web-site and letting the web-browser fork
a telnet client. This bug was reported by iDEFENSE [IDEF0865].

Note that this patch changes the behaviour of the telnet client
regarding the rule of exported environment variables. Please consult
the man page for further details."
