Buggy ATI Driver Leaves Vista Open to Attack 
Microsoft and AMD are fixing a bug in an ATI driver that leaves the Vista kernel open to attack.

Microsoft is working with AMD to fix a bug in an ATI driver that ships preinstalled on millions of laptops and which leaves the Vista kernel open to arbitrary memory writes by malicious driver authors.

It's not just ATI—virtualization security researcher Joanna Rutkowska said during her presentation at Black Hat earlier in August that ATI, which is owned by AMD, and Nvidia are just two examples of particularly badly written drivers, and that there could be tens of thousands of vulnerable drivers out there.

The bug in the ATI driver is that it allows arbitrary memory writes. Malicious driver authors can use that flaw to load unsigned drivers via the standard loading mechanism.
