It's not a good news to see how big is the last Microsoft Security Bulletin for October 2004: 10 vulnerabilities discovered (7 targeted as "critical" and 3 as "important") and 22 patches available (for different systems). All is included... patches for Windows, for Internet Explorer, for the Office Suite (Excel in particular).
It's the time again for a big patch of my machine... 
I don't know exactly the minimal details of all this new flaws, but I've a little question on my mind... all of this are totally new flaws or flaws previously discovered and now re-appeared (maybe after new patches)??
The first Service Pack for one of my favourite virtualization software is out...
