Revision Note: V1.0 (August 11, 2015): Bulletin published.
Summary: This security update helps to resolve an information disclosure vulnerability in Microsoft Windows, Internet Explorer, and Microsoft Office. To exploit the vulnerability an attacker would first have to use another vulnerability in Internet Explorer to execute code in the sandboxed process. The attacker could then execute Notepad, Visio, PowerPoint, Excel, or Word with an unsafe command line parameter to effect information disclosure. To be protected from the vulnerability, customers must apply the updates provided in this bulletin, as well as the update for Internet Explorer provided in MS15-079. Likewise, customers running an affected Microsoft Office product must also install the applicable updates provided in MS15-081.

Summary: This security update resolves vulnerabilities in Microsoft .NET Framework. The vulnerabilities could allow elevation of privilege if a user runs a specially crafted .NET application. However, in all cases, an attacker would have no way to force users to run the application; an attacker would have to convince users to do so.
