VERY Dangerous Hole of 4.3BSD UNIX Security !!!

[Ning Zhang]

Hello Net Folks,

I have post my report to Berkeley and have got a reply from there.
Mr.K.Bostic ask me do not distribute my report any more because I
am not sure it will not be abused or further redistributed. I am very
curious that he said my analysis was wrong, but the result is true.
He said the problem is somewhere else and Berkeley will post a fix
to the net today (dec 21).

I plan to rewrite my report with correct analysis. Any comments and
suggestion are welcome.
