Summary: This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of 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.

Revision Note: V1.0 (August 18, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in Internet Explorer. The vulnerability could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. 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.

Revision Note: V1.0 (August 11, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow information disclosure by either exposing memory addresses if a user clicks a specially crafted link or by explicitly allowing the use of Secure Sockets Layer (SSL) 2.0. However, in all cases an attacker would have no way to force users to click a specially crafted link; an attacker would have to convince users to click the link, typically by way of an enticement in an email or Instant Messenger message.

Severity Rating: Important
Revision Note: V1.0 (August 11, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application or convinces a user to open a specially crafted file that invokes a vulnerable sandboxed application, allowing an attacker to escape the sandbox.
