Summary

This security update helps resolve an information disclosure vulnerability in Windows, Internet Explorer, and Microsoft Office. To exploit the vulnerability, an attacker would first have to use another vulnerability in Internet Explorer to run code in the sandboxed process. The attacker could then run Notepad, Visio, PowerPoint, Excel, or Word by using an unsafe command-line parameter to effect information disclosure. To be protected from the vulnerability, customers must apply the updates that are provided in this bulletin and also the update for Internet Explorer that is provided in MS15-079. Similarly, customers who are running an affected Office product must also install the applicable updates that are provided in MS15-081.For more information about the updates that are required to address this vulnerability, see Microsoft Knowledge Base Article 3080057, Microsoft Knowledge Base Article 3080790, and Microsoft Knowledge Base Article 3082442.To learn more about the vulnerability, see Microsoft Security Bulletin MS15-088.
