[BusyBox] Are telnetd and login save?

[Steven Scholz]

Hi there,

I wonder if someone examined the telnetd or login utils that come with 
  busy if it's safe?

Or if we have to be prepared that someday someone comes up with an 
buffer overflow exploit (or whatever) that allows hin to break in to a 
busybox system (and get root access)?

Thanks,

Steven
