PCWorld: Microsoft has warned users of a bug in Windows' Canonical Display Driver that could affect anyone using the "Aero" interface in the 64-bit version of Windows 7. "If exploited, it would likely cause the affected system to stop responding and restart," Microsoft's Jerry Bryant wrote in a blog post. "Code execution, while possible in theory, would be very difficult due to memory randomization both in kernel memory and via Address Space Layout Randomization (ASLR)."
The company is working on a patch for the problem. In the meantime, users can protect themselves by selecting one of the black and white high contrast themes in their control panel settings.
