Oracle Outside In contains multiple exploitable vulnerabilities --------------------------------------------------------------- Remote code execution vulnerabilities exist in Microsoft Exchange Server through the WebReady Document Viewing feature. These vulnerabilities could allow remote code execution as Local System if a user views a specially crafted file through Outlook Web Access in a browser. An attacker who successfully exploited the vulnerabilities could run code on the affected server, but only as LocalService. The LocalService account has minimum privileges on the local computer and presents anonymous credentials on the network. To view these vulnerabilities as a standard entry in the Common Vulnerabilities and Exposures list, see [CVE-2012-1766](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1766), [CVE-2012-1767](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1767),[CVE-2012-1768](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1768), [CVE-2012-1769](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1769), [CVE-2012-1770](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1770), [CVE-2012-1771](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1771) , [CVE-2012-1772](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1772), [CVE-2012-1773](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-1773), [CVE-2012-3106](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-3106), [CVE-2012-3107](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-3107), [CVE-2012-3108](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-3108), [CVE-2012-3109](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-3109), and [CVE-2012-3110](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2012-3110). #### Mitigating Factors for Oracle Outside In contains multiple exploitable vulnerabilities Mitigation 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: - The transcoding service in Exchange that is used for WebReady Document Viewing is running in the LocalService account. The LocalService account has minimum privileges on the local computer and presents anonymous credentials on the network. #### Workarounds for Oracle Outside In contains multiple exploitable vulnerabilities Workaround 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: - **Disable WebReady document view** 1. Log in to the Exchange Management Shell as an Exchange Organization Administrator. 2. Issue the following PowerShell command: `Get-OwaVirtualDirectory | where {$_.OwaVersion -eq 'Exchange2007' -or $_.OwaVersion -eq 'Exchange2010'} | Set-OwaVirtualDirectory -WebReadyDocumentViewingOnPublicComputersEnabled:$False -WebReadyDocumentViewingOnPrivateComputersEnabled:$False` **Impact of workaround.** OWA users may not be able to preview the content of email attachments. **How do I undo the workaround?** 1. Log in to the Exchange Management Shell as an Exchange Organization Administrator. 2. Issue the following PowerShell command: `Get-OwaVirtualDirectory | where {$_.OwaVersion -eq 'Exchange2007' -or $_.OwaVersion -eq 'Exchange2010'} | Set-OwaVirtualDirectory -WebReadyDocumentViewingOnPublicComputersEnabled:$True -WebReadyDocumentViewingOnPrivateComputersEnabled:$True` **Note** The above steps assume the Exchange Administrator had previously allowed WebReady Documents to be viewed on both Public and Private logons to OWA. The appropriate $True or $False value should be used to set the desired behavior based upon user logon. #### FAQ for Oracle Outside In contains multiple exploitable vulnerabilities **What is the scope of the vulnerabilities?**  These are a remote code execution vulnerabilities. **What causes the vulnerabilities?**  The WebReady service parses files using the Oracle Outside In libraries in order to provide a preview of the document in the browser. The vulnerabilities are caused when WebReady Document Viewer is used to preview a specially crafted file. The mapping of CVE identifiers to the vulnerable file parsers are as follows: | CVE Identifier | Affected File Parser | |----------------|----------------------| | CVE-2012-1766 | CDR | | CVE-2012-1767 | DOC | | CVE-2012-1768 | DPT | | CVE-2012-1769 | JP2 | | CVE-2012-1770 | LWP | | CVE-2012-1771 | ODG | | CVE-2012-1772 | PCX | | CVE-2012-1773 | PDF | | CVE-2012-3106 | SAM | | CVE-2012-3107 | SXD | | CVE-2012-3108 | SXI | | CVE-2012-3109 | VSD | | CVE-2012-3110 | WSD | **What are the Oracle Outside In libraries?**  In Microsoft Exchange Server 2007 and Microsoft Exchange Server 2010, Outlook Web App (OWA) users are provided with a feature called WebReady Document Viewing that allows users to view certain attachments as a webpage instead of relying on local applications to open/view it. The Oracle Outside In libraries are used by the conversion process in the server backend to support the WebReady feature. Microsoft licenses these libraries from Oracle. **What is WebReady Document Viewer?**  WebReady Document Viewing allows users to view certain attachments as a webpage. Microsoft Exchange 2007 and Microsoft Exchange 2010 do the conversion, so the user doesn't need anything other than a web browser. **What might an attacker use these vulnerabilities to do?**  An attacker who successfully exploited these vulnerabilities could run arbitrary code as LocalService on the affected Exchange server. The LocalService account has minimum privileges on the local computer and presents anonymous credentials on the network. **How could an attacker exploit these vulnerabilities?**  An attacker could send an email message containing a specially crafted file to a user on an affected version of Exchange. When the user previews the specially crafted file in the browser, arbitrary code could be run on the Exchange server. An attacker could then install programs; view, change, or delete data; or take any other action that the server process has access to do. **What systems are primarily at risk from the vulnerabilities?**  Exchange server systems are primarily at risk from these vulnerabilities. **What does the update do?**  The update addresses the vulnerabilities by updating the affected Oracle Outside In libraries to a non-vulnerable version. **When this security bulletin was issued, had these vulnerabilities been publicly disclosed?**  Yes. This vulnerabilities have been publicly disclosed.

**/log<LogFile>** Equivalent of /l\* <LogFile>
**Note** You can combine these switches into one command. For backward compatibility, the security update also supports many of the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see [Microsoft Knowledge Base Article 262841](http://support.microsoft.com/kb/262841).

Verifying that the Update Has Been Applied

  • Microsoft Baseline Security Analyzer
    To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information.

  • File Version Verification
    Because there are several editions of Microsoft Windows, the following steps may be different on your system. If they are, see your product documentation to complete these steps.

    1. Click Start and then enter an update file name in the Start Search box.
    2. When the file appears under Programs, right-click the file name and click Properties.
    3. On the General tab, compare the file size with the file information tables provided in the bulletin KB article.
      Note Depending on the edition of the operating system, or the programs that are installed on your system, some files that are listed in the file information table may not be installed.
    4. You can also click the Details tab and compare information, such as file version and date modified, with the file information tables provided in the bulletin KB article.
      Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.
    5. Finally, you can also click the Previous Versions tab and compare file information for the previous version of the file with the file information for the new, or updated, version of the file.

  • Registry Key Verification
    You may also be able to verify the files that this security update has installed by reviewing the registry keys listed in the Reference Table in this section.

    These registry keys may not contain a complete list of installed files. Also, these registry keys may not be created correctly when an administrator or an OEM integrates or slipstreams this security update into the Windows installation source files.
