I am gotting that same bug which bites me: 

under screen, create virtual console (using PTY), run telnet/rlogin under it,
kill the shell process (telnet not killed), re-create virtual console 
(same PTY used), alas, I got input from shell/old telnet process intermixed.

secutity hole as well.

I remember discussion about this some time ago; was anything like a patch
fixing the problem issued? 

btw, are bug reports / solutions archived somewhere?
