screen buffer overflow

[Christian Pearce]

I compiled it for 7.2.  It seems to work fine.  I updated the bug.

I am not certain if we should choose to release this as a security fix.  Certainly if RedHat does for 9 we should.  If other distributions do we should as well.  Since we did the work at this point we should.
