Re: FreeBSD,rlogin and coredumps.

The problem is not in screen; it's in the operating system.
Linux is truly not vulnerable as it does not allow
coredumps of setuid root programs.

The BSDs (at least FreeBSD) appear to still do this for some
inane reason. Even SunOS 4.x doesn't coredump setuid progs, and
I wouldn't exactly call it secure.

It's possible to send a signal 11 to the latest version of screen
(3.7.2) and make it coredump with the master.passwd file in memory.
I'm using FreeBSD 2.1.5-RELEASE.
