Microsoft Warns of Win 7 Graphics Security Hole

A new Windows 7 graphics flaw has been exposed that could expose users of the 64-bit OS to experience non-responsive systems, restarts and unauthorized code execution.

Microsoft detailed in Security Advisory 2028859 that the vulnerability is to do with the Canonical Display Driver (cdd.dll), which is used by desktop composition to blend the Windows Graphics Device Interface (GDI) and DirectX drawing, and affects Windows 7 x64, Windows Server 2008 R2 x64, and Windows Server 2008 R2 for Itanium systems.

Microsoft says that there isn't a big worry because code execution would be "very difficult due to memory randomization both in kernel memory and via Address Space Layout Randomization (ASLR)." Still, those who are worried about security can simply disable Aero visual effects to keep this security flaw at bay until Microsoft issues a fix.

    Not unexpected, Windows has always been the vulnerable OS because of it's dominance, careful users and those with proper security software/settings should be fine :)

    dextermat-1 MS Wasn't there a similar case happened with windows xp and .jpg...They just never learn: Fix a security hole with one OS but not in the new one.Stop spending money on advertisement and put some in developing better software Ms retarded..


    That's right! Write thousands of lines of new code without encountering any bugs or errors! I'm not a programmer and I know everything! -_-

    randomizerDominance makes an OS vulnerable to attack, but it doesn't contribute to vulnerabilities in the design. That's just a development fault which needs to be corrected.


    All software have vulnerabilities. While some argue that the unix platform is inherently more secure, windows' dominance makes it much more apt to be carefully dissected for vulnerabilities. It is widely known that m$ has the best security policies period.

    "Canonical Display Driver"?! Did microsoft get a sense of humor?

    Agreed...there are numerous bugs, especially since Microsoft has looked to play with most hardware and software and as stated are the big player in the market (particularly business).

    I don't think we'll ever get to perfectly secure coding, so bugs/security holes will continue to exist.
