BACKGROUND\r\n\r\nMicrosoft PowerPoint is an application used for constructing\r\npresentations, and comes with the Microsoft Office suite. For more\r\ninformation, see the vendor's site found at the following link.\r\n\r\nhttp://office.microsoft.com/en-us/powerpoint/default.aspx\r\n\r\nII. DESCRIPTION\r\n\r\nRemote exploitation of a use-after-free vulnerability in Microsoft\r\nCorp.'s PowerPoint could allow an attacker to execute arbitrary code\r\nwith the privileges of the current user.\r\n\r\nThis vulnerability occurs when parsing multiple "OEPlaceholderAtom"\r\nrecords present in a "msofbtClientData" container. This record type is\r\nused to create a placeholder for an object #picture, text, etc.# on a\r\nslide. When a certain series of these records are present, it is\r\npossible to trigger a use-after-free vulnerability, which can lead to\r\nthe execution of arbitrary code.\r\n\r\nIII. ANALYSIS\r\n\r\nExploitation of this vulnerability results in the execution of arbitrary\r\ncode with the privileges of the user opening the file. To exploit this\r\nvulnerability, an attacker would need to convince a user to open a\r\nmalicious file. If the targeted user is running PowerPoint 2000 and the\r\n"Office Document Open Confirmation Tool" is not installed, then it is\r\npossible to exploit this vulnerability directly through the browser.\r\n\r\nIV. DETECTION\r\n\r\niDefense has confirmed the existence of this vulnerability in the\r\nfollowing versions of PowerPoint:\r\n\r\nPowerPoint 2002 #XP# SP3 PowerPoint 2003 SP3 PowerPoint 2007 and\r\nPowerPoint 2007 SP1 are not affected.\r\n\r\nV. WORKAROUND\r\n\r\niDefense is currently unaware of any workarounds for this issue.\r\n\r\nVI. VENDOR RESPONSE\r\n\r\nMicrosoft Corp. has released a patch which addresses this issue.\r\nInformation about downloadable vendor updates can be found by clicking\r\non the URLs shown.\r\nhttp://www.microsoft.com/technet/security/Bulletin/MS10-004.mspx\r\n\r\nVII.

The article also documents recommended solutions for these issues.\r\n\r\nWhy is the Microsoft Office PowerPoint Viewer 2003 not being offered an update package? \r\nThe Vulnerability FAQ for CVE-2010-0033 states that this update addresses the vulnerability by changing the way that Microsoft Office PowerPoint Viewer parses specially crafted PowerPoint files; however, no update package for the standalone PowerPoint Viewer 2003 is offered.\r\n\r\nThis is because standalone installations of the PowerPoint Viewer 2003 are past their support life cycle and will not be offered this update. Instead, this update is being offered to customers of Microsoft Office PowerPoint 2003 so that they may issue their updated version of their presentations created using the Package a Presentation for CD feature in PowerPoint which uses PowerPoint Viewer 2003.\r\n\r\nIt should be a priority for customers who have standalone installations of the PowerPoint Viewer 2003 to migrate to supported releases to prevent potential exposure to vulnerabilities. PowerPoint Viewer 2007 is not affected by the vulnerabilities described in this bulletin and is available from the Microsoft Download Center.\r\n\r\nMS10-003 also describes a vulnerability in Microsoft Office 2004 for Mac. How does MS10-003 relate to this bulletin (MS10-004)? \r\nAs part of the cumulative servicing model for Microsoft Office 2004 for Mac, this security update for Microsoft Office 2004 for Mac (KB979674) also addresses the vulnerability described in MS10-003. Users with Microsoft Office 2004 for Mac installed will have to install this security update but will only need to install it once.\r\n\r\nWhy does this update address several reported security vulnerabilities? \r\nThis update contains support for several vulnerabilities because the modifications that are required to address these issues are located in related files. Instead of having to install several updates that are almost the same, customers need to install this update only.\r\n\r\nThe Office component discussed in this article is part of the Office Suite that I have installed on my system; however, I did not choose to install this specific component. Will I be offered this update? \r\nYes, if the version of the Office Suite installed on your system shipped with the component discussed in this bulletin, the system will be offered updates for it whether the component is installed or not. The detection logic used to scan for affected systems is designed to check for updates for all components that shipped with the particular Office Suite and offer the updates to a system. Users who choose not to apply an update for a component that is not installed, but is included in the version of the Office Suite, will not increase the security risk of that system. However, users who do choose to install the update will not have a negative impact on the security or performance of a system. For more information on this issue, please see Microsoft Knowledge Base Article 830335..\r\n\r\nDoes the offer to update a non-vulnerable version of Microsoft Office constitute an issue in the Microsoft update mechanism? \r\nNo, the update mechanism is functioning correctly in that it detects a lower version of the files on the system than in the update package and thus, offers the update.\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. For more information about the product lifecycle, visit the Microsoft Support Lifecycle Web site.\r\n\r\nIt should be a priority for customers who have older releases of the software to migrate to supported releases to prevent potential exposure to vulnerabilities. To determine the support lifecycle for your software release, see Select a Product for Lifecycle Information. For more information about service packs for these software releases, see Lifecycle Supported Service Packs.\r\n\r\nCustomers who require custom support for older software must contact their Microsoft account team representative, their Technical Account Manager, or the appropriate Microsoft partner representative for custom support options. Customers without an Alliance, Premier, or Authorized Contract can contact their local Microsoft sales office. For contact information, visit the Microsoft Worldwide Information Web site, select the country in the Contact Information list, and then click Go to see a list of telephone numbers.

Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:\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\PowerPoint\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000001\r\n\r\nNote In order to use 'FileOpenBlock' with Microsoft Office 2003, all of the latest security updates for Microsoft Office 2003 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 922847 will be unable to open Office 2003 files or earlier versions in Office 2003.\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\PowerPoint\Security\FileOpenBlock]\r\n"BinaryFiles"=dword:00000000\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 .ppt, .pot, and .pps file formats. The following table describes the command to enable or to disable MOICE for the .ppt, .pot, and .pps file formats:\r\nCommand to enable MOICE to be the registered handler\tCommand to disable MOICE as the registered handler\r\n\r\nASSOC .PPT=oice.powerpoint.show\r\n\t\r\n\r\nASSOC .ppt=PowerPoint.Show.8\r\n\r\nASSOC .POT=oice.powerpoint.template\r\n\t\r\n\r\nASSOC .PPS=oice.powerpoint.slideshow\r\n\r\nASSOC .PPS=oice.powerpoint.slideshow\r\n\t\r\n\r\nASSOC .pps=PowerPoint.SlideShow.8\r\n\r\nNote On Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, 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\nTop of sectionTop of section\r\n\t\r\nFAQ for PowerPoint LinkedSlideAtom Heap Overflow Vulnerability - CVE-2010-0030\r\n\r\nWhat is the scope of the vulnerability? \r\nThis is a remote code execution vulnerability.
