Revision Note: V1.1 (May 25, 2016): Removed the mitigating factors for CVE-2015-6131 and CVE-2015-6127. These are informational changes only.
Summary: This security update resolves vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if Windows Media Center opens a specially crafted Media Center link (.mcl) file that references malicious code. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
