Severity Rating: CriticalRevision Note: V1.1 (November 8, 2016): Revise bulletin to announce a detection change to address an issue in supersedence, specifically in WSUS environments where various updates applicable to Windows 7 SP1 and Windows Server 2008 R2 SP1 were incorrectly marked as being superseded. This is a detection change only. There were no changes to the update files. Customers who have already successfully installed the update do not need to take any action
Summary: This security update resolves vulnerabilities in Microsoft Windows, Microsoft Office, Skype for Business, Silverlight and Microsoft Lync. The most serious of these vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document. 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.
