...when did Adobe get to import masses of userspace code into the kernel, Microsofts ongoing huge mistake? A mistake founded on their continuing preference for screwing competitors over looking after customer security, accompanied by an unjustified belief in the quality of the their own code.
What Adobe tells us though is you don't even need the special privileges Microsoft give their own userspace software to break a Windows system, Adobe may be shite but security failures in their shitware are also failures in the underlying OS.
Windows is still based on adding security to a fundamentally unsecured OS, this is security by moving target. If only the snipers weren't quicker than Microsoft.
