Instead of having to install several updates that are almost the same, customers need to install this update only.\r\n\r\nWhat components of the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats are updated by this bulletin? \r\nThe update included with this security bulletin applies only to the specific component within the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats that is affected. For example, in an Excel bulletin, only the Excel compatibility pack component files are included in the update packages and not Word or PowerPoint compatibility pack component files. Word compatibility pack component files are updated in a Word bulletin and PowerPoint compatibility pack component files are updated in a PowerPoint bulletin.\r\n\r\nWhat is the Microsoft Office Excel Viewer? \r\nThe Microsoft Office Excel Viewer is a replacement for all previous Excel Viewer versions, including Excel Viewer 97 and Excel Viewer 2003. With Excel Viewer, you can open, view, and print Excel workbooks, even if you don't have Excel installed. You can also copy data from Excel Viewer to another program. However, you cannot edit data, save a workbook, or create a new workbook.\r\n\r\nI am using an older release of the software discussed in this security bulletin. What should I do? \r\nThe affected software listed in this bulletin have been tested to determine which releases are affected. Other releases are past their support life cycle.

Office Excel that could allow remote code execution if a user opens a specially crafted Excel file that includes a malformed record object. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\r\n\r\nTo view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2009-0549.\r\n\t\r\nMitigating Factors for Record Pointer Corruption Vulnerability - CVE-2009-0549\r\n\r\nMitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:\r\n\u2022\t\r\n\r\nThe vulnerability cannot be exploited automatically through e-mail. For an attack to be successful, a user must open an attachment that is sent in an e-mail message.\r\n\u2022\t\r\n\r\nAn attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.\r\n\u2022\t\r\n\r\nUsers who have installed and are using the Office Document Open Confirmation Tool for Office 2000 will be prompted with Open, Save, or Cancel before opening a document. The features of the Office Document Open Confirmation Tool are incorporated in Office XP and later editions of Office.\r\nTop of sectionTop of section\r\n\t\r\nWorkarounds for Record Pointer Corruption Vulnerability - CVE-2009-0549\r\n\r\nWorkaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:\r\n\u2022\t\r\n\r\nUse the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or untrusted sources\r\n\r\nThe Microsoft Office Isolated Conversion Environment (MOICE) will protect Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files.\r\n\r\nTo install MOICE, you must have Office 2003 or 2007 Office system installed.\r\n\r\nTo install MOICE, you must have the Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. The compatibility pack is available as a free download from the Microsoft Download Center:\r\n\r\nDownload the FileFormatConverters.exe package now\r\n\r\nMOICE requires all updates that are recommended for all Office programs. Visit Microsoft Update to install all recommended updates:\r\n\r\nhttp://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us\r\n\r\nTo enable MOICE, change the registered handler for the .xls, .xlt, and .xla file formats. The following table describes the command to enable or to disable MOICE for the .xls, .xlt, and .xla file formats:\r\nCommand to enable MOICE to be the registered handler\tCommand to disable MOICE as the registered handler\r\n\r\nASSOC .XLS=oice.excel.sheet\r\n\t\r\n\r\nASSOC .xls=Excel.Sheet.8\r\n\r\nASSOC .XLT=oice.excel.template\r\n\t\r\n\r\nASSOC .xlt=Excel.Template\r\n\r\nASSOC .XLA=oice.excel.addin\r\n\t\r\n\r\nASSOC .xla=Excel.Addin\r\n\r\nNote On Windows Vista and Windows Server 2008, the commands above will need to be run from an elevated command prompt.\r\n\r\nFor more information on MOICE, see Microsoft Knowledge Base Article 935865.\r\n\r\nImpact of workaround. Office 2003 and earlier formatted documents that are converted to the 2007 Microsoft Office System Open XML format by MOICE will not retain macro functionality. Additionally, documents with passwords or that are protected with Digital Rights Management cannot be converted.\r\n\u2022\t\r\n\r\nUse Microsoft Office File Block policy to block the opening of Office 2003 and earlier documents from unknown or untrusted sources and locations\r\n\r\nThe following registry scripts can be used to set the File Block policy.\r\n\r\nNote Modifying the Registry incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from incorrect modification of the Registry can be solved. Modify the Registry at your own risk.\r\n\u2022\t\r\n\r\nFor Office 2003\r\n\r\nWindows Registry Editor Version 5.00\r\n[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000001\r\n\r\nNote In order to use 'FileOpenBlock' with Office 2003, all of the latest Office 2003 security updates must be applied.\r\n\r\nImpact of workaround. Users who have configured the File Block policy and have not configured a special \u201cexempt directory\u201d as discussed in Microsoft Knowledge Base Article 922848 will be unable to open Office 2003 files or earlier versions in Office 2003 or 2007 Microsoft Office System.\r\n\r\nHow to undo the workaround:\r\n\u2022\t\r\n\r\nFor Office 2003\r\n\r\nWindows Registry Editor Version 5.00\r\n[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000000\r\n\u2022\t\r\n\r\nDo not open or save Excel files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file.\r\nTop of sectionTop of section\r\n\t\r\nFAQ for Record Pointer Corruption Vulnerability - CVE-2009-0549\r\n\r\nWhat is the scope of the vulnerability? \r\nThis is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. An attacker could then install programs or view, change, or delete data; or create new accounts with full user rights.\r\n\r\nWhat causes the vulnerability? \r\nThe vulnerability exists in the way that Microsoft Office Excel parses the Excel spreadsheet file format that could allow remote code execution when opening a specially crafted Excel spreadsheet.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nThis vulnerability requires that a user open a specially crafted Excel spreadsheet with an affected version of Microsoft Office Excel.\r\n\r\nIn an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially crafted Excel file to the user and by convincing the user to open the file.\r\n\r\nIn a Web-based attack scenario, an attacker would have to host a Web site that contains an Office file that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site, and then convince them to open the specially crafted Excel file.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nSystems where Microsoft Office Excel is used, including workstations and terminal servers, are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.\r\n\r\nWhat does the update do? \r\nThis update addresses the vulnerability by changing the way that Microsoft Office Excel parses specially crafted Excel files.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nNo. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nNo. Microsoft had not received information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.\r\nTop of sectionTop of section\r\nTop of sectionTop of section\r\n\t\r\nObject Record Corruption Vulnerability - CVE-2009-0557\r\n\r\nA remote code execution vulnerability exists in Microsoft Office Excel that could allow remote code execution if a user opens a specially crafted Excel file that includes a malformed record object.

An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. An attacker could then install programs or view, change, or delete data; or create new accounts with full user rights.\r\n\r\nWhat causes the vulnerability? \r\nThe vulnerability exists in the way that Microsoft Office Excel parses the Excel spreadsheet file format that could allow remote code execution when opening a specially crafted Excel spreadsheet.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nThis vulnerability requires that a user open a specially crafted Excel spreadsheet with an affected version of Microsoft Office Excel.\r\n\r\nIn an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially crafted Excel file to the user and by convincing the user to open the file.\r\n\r\nIn a Web-based attack scenario, an attacker would have to host a Web site that contains an Office file that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site, and then convince them to open the specially crafted Excel file.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nSystems where Microsoft Office Excel is used, including workstations and terminal servers, are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.\r\n\r\nWhat does the update do? \r\nThis update addresses the vulnerability by changing the way that Microsoft Office Excel parses specially crafted Excel files.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nNo. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nNo. Microsoft had not received information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.\r\nTop of sectionTop of section\r\nTop of sectionTop of section\r\n\t\r\nString Copy Stack-Based Overrun Vulnerability - CVE-2009-0559\r\n\r\nA remote code execution vulnerability exists in Microsoft Office Excel that could allow remote code execution if a user opens a specially crafted Excel file that includes a malformed record object.

Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:\r\n\u2022\t\r\n\r\nUse the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or untrusted sources\r\n\r\nThe Microsoft Office Isolated Conversion Environment (MOICE) will protect Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files.\r\n\r\nTo install MOICE, you must have Office 2003 or 2007 Office system installed.\r\n\r\nTo install MOICE, you must have the Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. The compatibility pack is available as a free download from the Microsoft Download Center:\r\n\r\nDownload the FileFormatConverters.exe package now\r\n\r\nMOICE requires all updates that are recommended for all Office programs. Visit Microsoft Update to install all recommended updates:\r\n\r\nhttp://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us\r\n\r\nTo enable MOICE, change the registered handler for the .xls, .xlt, and .xla file formats. The following table describes the command to enable or to disable MOICE for the .xls, .xlt, and .xla file formats:\r\nCommand to enable MOICE to be the registered handler\tCommand to disable MOICE as the registered handler\r\n\r\nASSOC .XLS=oice.excel.sheet\r\n\t\r\n\r\nASSOC .xls=Excel.Sheet.8\r\n\r\nASSOC .XLT=oice.excel.template\r\n\t\r\n\r\nASSOC .xlt=Excel.Template\r\n\r\nASSOC .XLA=oice.excel.addin\r\n\t\r\n\r\nASSOC .xla=Excel.Addin\r\n\r\nNote On Windows Vista and Windows Server 2008, the commands above will need to be run from an elevated command prompt.\r\n\r\nFor more information on MOICE, see Microsoft Knowledge Base Article 935865.\r\n\r\nImpact of workaround. Office 2003 and earlier formatted documents that are converted to the 2007 Microsoft Office System Open XML format by MOICE will not retain macro functionality. Additionally, documents with passwords or that are protected with Digital Rights Management cannot be converted.\r\n\u2022\t\r\n\r\nUse Microsoft Office File Block policy to block the opening of Office 2003 and earlier documents from unknown or untrusted sources and locations\r\n\r\nThe following registry scripts can be used to set the File Block policy.\r\n\r\nNote Modifying the Registry incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from incorrect modification of the Registry can be solved. Modify the Registry at your own risk.\r\n\u2022\t\r\n\r\nFor Office 2003\r\n\r\nWindows Registry Editor Version 5.00\r\n[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000001\r\n\r\nNote In order to use 'FileOpenBlock' with Office 2003, all of the latest Office 2003 security updates must be applied.\r\n\u2022\t\r\n\r\nFor 2007 Office system\r\n\r\nWindows Registry Editor Version 5.00\r\n[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000001\r\n\r\nNote In order to use 'FileOpenBlock' with the 2007 Microsoft Office system, all of the latest security updates for the 2007 Microsoft Office system must be applied.\r\n\r\nImpact of workaround. Users who have configured the File Block policy and have not configured a special \u201cexempt directory\u201d as discussed in Microsoft Knowledge Base Article 922848 will be unable to open Office 2003 files or earlier versions in Office 2003 or 2007 Microsoft Office System.\r\n\r\nHow to undo the workaround:\r\n\u2022\t\r\n\r\nFor Office 2003\r\n\r\nWindows Registry Editor Version 5.00\r\n[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000000\r\n\u2022\t\r\n\r\nFor 2007 Office system\r\n\r\nWindows Registry Editor Version 5.00\r\n[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000000\r\n\u2022\t\r\n\r\nDo not open or save Excel files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file.\r\nTop of sectionTop of section\r\n\t\r\nFAQ for Record Pointer Corruption Vulnerability - CVE-2009-1134\r\n\r\nWhat is the scope of the vulnerability? \r\nThis is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. An attacker could then install programs or view, change, or delete data; or create new accounts with full user rights.\r\n\r\nWhat causes the vulnerability? \r\nThe vulnerability exists in the way that Microsoft Office Excel parses the Excel spreadsheet file format that could allow remote code execution when opening a specially crafted Excel spreadsheet.\r\n\r\nWhat might an attacker use the vulnerability to do? \r\nAn attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.\r\n\r\nHow could an attacker exploit the vulnerability? \r\nThis vulnerability requires that a user open a specially crafted Excel spreadsheet with an affected version of Microsoft Office Excel.\r\n\r\nIn an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially crafted Excel file to the user and by convincing the user to open the file.\r\n\r\nIn a Web-based attack scenario, an attacker would have to host a Web site that contains an Office file that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site, and then convince them to open the specially crafted Excel file.\r\n\r\nWhat systems are primarily at risk from the vulnerability? \r\nSystems where Microsoft Office Excel is used, including workstations and terminal servers, are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.\r\n\r\nWhat does the update do? \r\nThis update addresses the vulnerability by changing the way that Microsoft Office Excel parses specially crafted Excel files.\r\n\r\nWhen this security bulletin was issued, had this vulnerability been publicly disclosed? \r\nNo. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.\r\n\r\nWhen this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? \r\nNo. Microsoft had not received information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.\r\n\r\nOther Information\r\nAcknowledgments\r\n\r\nMicrosoft thanks the following for working with us to help protect customers:\r\n\u2022\t\r\n\r\nBing Liu of Fortinet's FortiGuard Global Security Research Team for reporting the Pointer Corruption Vulnerability (CVE-2009-0549)\r\n\u2022\t\r\n\r\nBing Liu of Fortinet's FortiGuard Global Security Research Team for reporting the Object Record Corruption Vulnerability (CVE-2009-0557)\r\n\u2022\t\r\n\r\nCarsten H.
