  Vendor Reference

  MS10-077

  CVE Reference

  CVE-2010-3228

  CVSS Scores

  Base 9.3 / Temporal 6.9

  Description

  The Microsoft .NET Framework is a software framework for computers running Microsoft Windows operating systems.

  A remote code execution vulnerability exists in the Microsoft .NET Framework that can allow a specially crafted Microsoft .NET application to access memory in an unsafe manner, leading to arbitrary unmanaged code execution. This vulnerability only affects the x64 and Itanium architectures. (CVE-2010-3228).

  Microsoft has released a security update that addresses the vulnerability by modifying the way that the JIT compiler optimizes code.

  This security update is rated Critical for Microsoft .NET Framework 4.0 on supported x64-based and Itanium-based editions of Microsoft Windows.

  Consequence

  Successfully exploiting this vulnerability could allow remote code execution on a client system if a user views a specially crafted Web page using a Web browser that can run XAML Browser Applications (XBAPs). The vulnerability could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and then executes the page, as could be the case in a Web hosting scenario.

  Refer to Microsoft Security Bulletin MS10-077 for further details.

  Workaround:
  1) Disable partially trusted Microsoft .NET applications.

  Impact of workaround #1: Some Microsoft .NET applications will not run.

  2) Disable XAML browser applications in Internet Explorer

  Impact of workaround #2: Microsoft .NET code will not run in Internet Explorer or will not run without prompting. Disabling Microsoft .NET applications and components in the Internet and local Intranet security zones may cause some Web sites to work incorrectly.

  Refer to Microsoft Security Bulletin MS10-079 for further details.

  Workarounds:
  1) Avoid opening Office (Word) files received from untrusted 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 Excel Viewer Service Pack 2

  Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats Service Pack 2

  Refer to Microsoft Security Bulletin MS10-080 for further details.

  Workaround:
  1) Avoid opening Office files received from untrusted sources.

  2) Use the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or untrusted 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.

  90657

  Vendor Reference

  MS10-086

  CVE Reference

  CVE-2010-3223

  CVSS Scores

  Base 7.5 / Temporal 5.5

  Description

  A tampering vulnerability exists in the way the Failover Cluster Manager user interface handles permissions on shared cluster disks.

  This vulnerability exists because the Failover Cluster Manager uses unsecured default permissions when adding disks to a cluster. When an administrator adds a disk to a shared cluster, the Failover Cluster Manager sets permissions on the shared cluster disk in a way that potentially provides unauthorized users (everyone) with read/write/delete access to the administrative shares on the failover cluster disk. (CVE-2010-3223)

  Microsoft has released a security update that addresses this vulnerability by changing the way the Microsoft Cluster Service user interface sets permissions on administrative shares when adding or creating new shared cluster disks.

  This security update is rated Moderate for all supported editions of Windows Server 2008 R2.

  Consequence

  An attacker who successfully exploited this vulnerability could arbitrarily add, change, delete, or read data on an affected file system.
