THIS just hit the wire Friday morning. Once exploits are created to take advantage of this, there will be much wailing and gnashing of teeth.
“This week at the Black Hat Security Conference two security researchers will discuss their findings which could completely bring Windows Vista to its knees.
Mark Dowd of IBM Internet Security Systems (ISS) and Alexander Sotirov, of VMware Inc. have discovered a technique that can be used to bypass all memory protection safeguards that Microsoft built into Windows Vista. (emphasis added)
The researchers were able to load whatever content they wanted into any location they wished on a user’s machine using a variety of objects, such as Java, ActiveX and even .NET objects. This feat was achieved by taking advantage of the way that Internet Explorer (and other browsers) handle active scripting in the Operating System.
While this may seem like any standard security hole, other researchers say that the work is a major breakthrough and there is very little that Microsoft can do to fix the problems. These attacks work differently than other security exploits, as they aren’t based on any new Windows vulnerabilities, but instead take advantage of the way Microsoft chose to guard Vista’s fundamental architecture.”
Glorious. Simply glorious.
