Customers who have already successfully updated their systems do not need to take any action.Summary: This security update resolves two privately reported vulnerabilities in Microsoft Windows. These vulnerabilities could allow remote code execution if a user opens a specially crafted media file or receives specially crafted streaming content from a Web site or any application that delivers Web content.

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.
