A remote code execution vulnerability exists in WINS due to insufficient validations for the data structures within specially crafted WINS network packets sent to the WINS service.
Microsoft has released a security update to resolve the vulnerability by correcting a logic error that occurs when buffers are passed as parameters.
This security update is rated Critical for servers running supported editions of Windows Server 2003, Windows Server 2008 (except Itanium), and Windows Server 2008 R2 (except Itanium), on which WINS is installed.
NOTE: Non Local detection (Remote check) will work only on 2003 Operating systems.

- A remote code execution vulnerability exists in the way that Microsoft PowerPoint handles specially crafted PowerPoint files. (CVE-2011-1269)
- A remote code execution vulnerability exists in the way that Microsoft PowerPoint handles specially crafted PowerPoint files. (CVE-2011-1270)
Microsoft has released an update that addresses the vulnerabilities by correcting the way that PowerPoint handles memory when parsing specially crafted PowerPoint files.
This security update is rated Important for all supported editions of Microsoft PowerPoint 2002, Microsoft PowerPoint 2003, Microsoft PowerPoint 2007, Microsoft Office 2004 for Mac and Microsoft Office 2008 for Mac. The security update is also rated Important for all supported versions of Open XML File Format Converter for Mac and Microsoft Office Compatibility Pack.
Microsoft Office XP Service Pack 3 (Microsoft PowerPoint 2002 Service Pack 3)
Microsoft Office 2003 Service Pack 3 (Microsoft PowerPoint 2003 Service Pack 3)
Microsoft Office 2007 Service Pack 2 (Microsoft PowerPoint 2007 Service Pack 2)
Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats Service Pack 2
Refer to Microsoft Security Bulletin MS11-036 for further details.
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 workaround #2:
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. The following registry scripts can be used to set the File Block policy.
Impact of workaround #3:
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.
4)Set Office File Validation to disable editing in protected view in PowerPoint 2003.
Impact of workaround #4: Office File Validation will no longer allow the editing of suspicious files.
