  Workaround:
  1) Avoid opening Office files received from un-trusted sources.

  2) Use the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or un-trusted sources because it protects Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files. Information on MOICE can be found at KB935865.

  Impact of the workaround:
  Office 2003 and earlier formatted documents that are converted to the 2007 Microsoft Office System Open XML format by MOICE lose their macro functionality. Documents protected with passwords and Digital Rights Management cannot be converted.

  3) Microsoft Office File Block policy should be used to block the opening of Office 2003 and earlier documents from unknown or untrusted sources.

  Impact of the workaround:
  If File Block policy is configured without special "exempt directory" configuration (see KB922848), Office 2003 files or earlier versions will not open in Office 2003 or 2007 Microsoft Office System.

  Microsoft .NET Framework is prone to a tampering vulnerability. The vulnerability is caused by the way that the W3C XML Signature Syntax and Processing (XMLDsig) recommendation has been implemented in the Microsoft .NET Framework. (CVE-2009-0217)

  Microsoft has released a security update that addresses the vulnerability by changing the way in which the XMLDsig recommendation has been implemented in the Microsoft .NET Framework. This security update is rated Important for all affected releases of Microsoft .NET Framework for Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2.

  Consequence

  An attacker who successfully exploits this vulnerability could bypass certain cryptographic signatures and as a result, tamper with signed XML content without the receiver detecting the changes. If the message is changed completely from its original meaning, this may also constitute spoofing. In situations where a developer has written an application that relies on HMAC signed XML content, the security impact depends on the specific usage scenario for that application.
