Damn, I wish I had said out loud what I was thinking earlier this week...
"I bet there aren't any patches this month"
This is something of a watershed moment for Microsoft - nothing critical seems to have happened this month.
The Inquirer is claiming that there are seven outstanding IE exploits (see the Secunia advisory) but I've just tried them all on Windows XP Home SP1, including last month's patch and none of the exploits work. I believe that last month's patch has actually eliminated these exploits. Secunia's page was last updated on the 8th of October.
