Windows Exploit Advisory

We are aware of recent activity in the form of specific exploits in the wild targeting Microsoft Windows Vulnerabilities and the potential to exploit the vast majority of Microsoft operating systems. The first vulnerability (CVE-2014-6352) allows threat actors to execute code on a victim’s machine after visiting a maliciously crafted webpage. The second actively targeted vulnerability (CVE-2014-6324) may allow domain users to elevate their privileges to Domain Administrator. The third vulnerability (CVE-2014-6321) has not been actively seen in the wild but has the potential for the greatest impact. Patches for all three of these vulnerabilities should be applied as soon as possible with verification that they have been applied successfully.
