Qualys Vulnerability R&D Lab has released new vulnerability checks in the Qualys Cloud Platform to protect organizations against 2 vulnerabilities that were fixed in 2 bulletins announced today by Microsoft. Customers can immediately audit their networks for these and other new vulnerabilities by accessing their Qualys subscription. Visit our blog to see how to prioritize remediation.
Microsoft has released 2 security bulletins to fix newly discovered flaws in their software. Qualys has released the following checks for these new vulnerabilities:
Windows Mail is prone to a vulnerability is caused when a common library used by Outlook Express and Windows Mail insufficiently validates network data before using that data to calculate the necessary size of a buffer. The vulnerability could allow remote code execution if a user visits a malicious email server.
Microsoft has released a security update that addresses the vulnerability by correctly validating email server responses. The security update is rated Critical for Microsoft Outlook Express on all supported editions of Microsoft Windows 2000, Windows XP, and Windows Server 2003; and for Windows Mail on all supported editions of Windows Vista and Windows Server 2008. The security update is rated Important for Windows Live Mail on all supported editions of Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2; and for Windows Mail on all supported editions of Windows 7 and Windows Server 2008 R2.
Windows Embedded Systems:- For additional information regarding security updates for embedded systems, refer to the following MSDN blog(s):
June 2010 Security Updates are Available on ECE for Standard 09and XP Embedded (KB978542, 978542)
May 2010 Security Updates for XPe\Standard 2009 are Finally Available on ECE (KB978542, 978542)
Updates for Windows Embedded Standard 7 Are Now Available (KB978542)
An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Use web-based email instead of IMAP or POP3 to check email.
A stack-based memory corruption vulnerability exists in VBE6.dll . The vulnerability is caused by the way that VBA searches for ActiveX controls in a document that supports VBA. As a result, it is possible for a host application, such as Microsoft Office or a third-party application developed for Visual Basic programmability, to pass a specially crafted document with embedded ActiveX controls to the VBA runtime creating a condition that could allow arbitrary code to be run.
Microsoft has released a security update that addresses this vulnerability by modifying the way that Visual Basic for Applications searches for ActiveX Controls embedded in documents.
Refer to Microsoft Security Bulletin MS10-031 for further details.
1) Disable ActiveX controls in the 2007 Microsoft Office System
Impact of workaround #1: Embedded ActiveX controls (such as macros) will not run in Office documents.
2) Restrict access to VBE6.dll
Impact of workaround #2: Embedded ActiveX controls (such as macros) will not run in Office documents. For instance, users will be unable to insert objects into Office documents.
3) 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.
4) Do not open or save untursted Microsoft Office files
Detailed information on applying the workarounds is available at Microsoft Security Bulletin MS10-031.
