Hi everyone. As part of our usual monthly update cycle, today Microsoft is releasing four security bulletins to address five vulnerabilities in Windows and Microsoft Office.
MS10-042 resolves a publicly disclosed and actively exploited vulnerability discussed in Security Advisory 2219475.

Even though this issue affects Server 2003, we have not found an attack vector on that platform so the severity rating is Low. Windows XP customers should install this update as soon as possible.
MS10-043 resolves a publicly disclosed vulnerability in the Canonical Display Driver (cdd.dll). Although it is possible that the vulnerability could allow code execution, successful code execution is unlikely due to memory randomization. In most scenarios, it is much more likely that an attacker who successfully exploited this vulnerability could cause a Denial of Service (DoS). Note that this bulletin affects only 64-bit versions of Windows 7 and Windows Server 2008 R2 with Windows Aero enabled. Aero is not installed by default on Server 2008 R2.
