Re: hacker's dream [Win95]


This article is basically true. I'm not sure what they mean be "creating 
a simple file on your local machine," though. Anybody?

Microsoft appears to have patched the SMB and C$ bugs, but in the 
US/English release only. Yusuf Mehdi sent me email Thursday promising 
that international patches would be available *within two weeks* --
there  was no explanation for the delay, and I can think of none.

This is discussed a bit in article <[email protected]>
and folowups, and a bunch of places on
