When FreeBSD discovered this about a month ago and it appeared on
bugtraq(*), I forwarded the info to security-officer, and received
word back it had been fixed. I can't find the actual message,
unfortunately, but I found another message referring to it.
If the fix didn't in fact make it in that time (would have been
Feb. 17th or 18th, I believe)... well, that's kinda bad. :(
(*) Nobody on bugtraq mentioned any of the interesting possibilities
besides being able to get rlogin cores and thus maybe shadow
passwords. I've been waiting for AUSCERT so I haven't posted it
myself...
