With this September Microsoft Patch Tuesday update, we see again a relatively small set of updates in comparison to the lists of updates released by Microsoft in the previous months. In total there are five Microsoft Security Updates with the rating of Important. This is a minor update from Microsoft and the potential impact for the updates is likely to be moderate.
As part of the Patch Tuesday Security Update analysis performed by the ChangeBASE AOK team, we have seen very little cause for potential compatibility issues.
Given the nature of the changes and updates included in each of these patches, most systems will require a reboot to successfully implement any and all of the patches and updates released in this September Patch Tuesday release cycle.

Security Update Detailed Summary
MS11-070 Vulnerability in WINS Could Allow Elevation of Privilege (2571621)
Description This security update resolves a privately reported vulnerability in the Windows Internet Name Service (WINS). The vulnerability could allow elevation of privilege if a user received a specially crafted WINS replication packet on an affected system running the WINS service. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
Payload W03a3409.dll, Wins.exe, Winsevnt.dll, Ww03a3409.dll, Wwins.exe, Wwinsevnt.dll
Impact Important - Elevation of Privilege
MS11-071 Vulnerability in Windows Components Could Allow Remote Code Execution (2570947)
Description This security update resolves a publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate rich text format file (.rtf), text file (.txt), or Word document (.doc) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. An 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.
Payload Imjpapi.dll
Impact Important - Remote Code Execution
MS11-072 Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2587505)
Description This security update resolves five privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Excel file. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the logged-on 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. Installing and configuring Office File Validation (OFV) to prevent the opening of suspicious files blocks the attack vectors for exploiting the vulnerabilities described in CVE-2011-1986 and CVE-2011-1987.
Payload Excel.exe
Impact Important - Remote Code Execution
MS11-073 Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2587634)
Description This security update resolves two privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Office file or if a user opens a legitimate Office file that is located in the same network directory as a specially crafted library file. An attacker who successfully exploited either of the vulnerabilities could gain the same user rights as the logged on 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.
Payload Ietag.dll, Mso.dll
Impact Important - Remote Code Execution
MS11-074 Vulnerabilities in Microsoft SharePoint Could Allow Elevation of Privilege (2451858)
Description This security update resolves five privately reported vulnerabilities and one publicly disclosed vulnerability in Microsoft SharePoint and Windows SharePoint Services. The most severe vulnerabilities could allow elevation of privilege if a user clicked on a specially crafted URL or visited a specially crafted Web site. For the most severe vulnerabilities, Internet Explorer 8 and Internet Explorer 9 users browsing to a SharePoint site in the Internet Zone are at a reduced risk because, by default, the XSS Filter in Internet Explorer 8 and Internet Explorer 9 helps to block the attacks in the Internet Zone. The XSS Filter in Internet Explorer 8 and Internet Explorer 9, however, is not enabled by default in the Intranet Zone.
Payload Groove.exe, Groovedocumentsharetool.dll, Grooveutil.dll, Groovewebplatformservices.dll, Groovewebservices.dll
Impact Important - Elevation of Privilege
