Microsoft will be releasing its September’s Patch Tuesday updates this Tuesday, September 10. Four of the four critical bulletins will address a Remote Code Execution flaw in Microsoft Office that can be triggered simply by previewing an email in Outlook, even without explicitly opening the e-mail. The remaining 10 bulletins are all rated important by Microsoft, four of them patch remote code execution flaws in Office, while three other privilege escalation flaws are being fixed in Windows and Office. Microsoft does not get into detail about the vulnerabilities, because the patches have not been rolled out.
