Yesterday’s patch day was an important one. IE 7 sploits that can be crafted easily, and a SQL sploit that has functional exploit code published. F-Secure has done a good overview here.
I do hope that admins have taken to heart lessons about patching in light of Conficker/Downadup. That bug has hit a lot of companies, even stalling an entire city police department and grounding French military fighter planes.
