Summary: This security update resolves vulnerabilities in Windows Hyper-V. The vulnerabilities could allow remote code execution in a host context if a specially crafted application is run by an authenticated and privileged user on a guest virtual machine hosted by Hyper-V. An an attacker must have valid logon credentials for a guest virtual machine to exploit this vulnerability.

Severity Rating: Important

Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if the Windows Installer service improperly runs custom action scripts. An attacker must first compromise a user who is logged on to the target system to exploit the vulnerability. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.

Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker who is logged on to a domain-joined system runs a specially crafted application that could establish a connection with other domain-joined systems as the impersonated user or system. The attacker must be logged on to a domain-joined system and be able to observe network traffic.

Severity Rating: Critical
Revision Note: V1.0 (July 14, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in the VBScript scripting engine in Microsoft Windows. The vulnerability could allow remote code execution if a user visits a specially crafted website. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if the Windows graphics component fails to properly process bitmap conversions. An authenticated attacker who successfully exploited this vulnerability could elevate privileges on a targeted system. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights. An attacker must first log on to the system to exploit this vulnerability.

Revision Note: V1.0 (July 14, 2015): Bulletin published.
Summary: This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities 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 (July 14, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability, which exists in Windows Remote Procedure Call (RPC) authentication, could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application. An attacker who successfully exploited this vulnerability could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Revision Note: V1.0 (July 14, 2015): Bulletin published.
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.

Summary: This security update resolves vulnerabilities in Microsoft SQL Server. The most severe vulnerabilities could allow remote code execution if an authenticated attacker runs a specially crafted query that is designed to execute a virtual function from a wrong address, leading to a function call to uninitialized memory. To exploit this vulnerability an attacker would need permissions to create or modify a database.
