There are four more security updates, each rated important: one to fix remote code execution vulnerability in Visual Studio and three other updates that prevent users from elevating access privilege levels in Windows, Windows Services for Unix, MSN Messenger, Windows Live Messenger and SharePoint Services.
Remote code execution vulnerabilities continue to dominate the patches Microsoft issues each month. September's critical patch for Windows will make a total of 35 critical patches issued this year to prevent hackers from taking control of network computers over the Internet.
Microsoft also said it will release one non-security, high-priority update on Microsoft Update (MU) and Windows Server Update Services (WSUS). More information about the non-security patch will be available next week.
To find out if computer systems need all or any of these updates, companies can use Microsoft's Baseline Security Analyzer and its Enterprise Update Scan Tool.
An updated version of the Microsoft Windows Malicious Software Removal Tool will also be released next week on Windows Update, MU, WSUS and Microsoft's download center.
