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.

Summary: This security update resolves vulnerabilities in Microsoft Exchange Server. The most severe of the vulnerabilities could allow elevation of privilege if a user clicks a specially crafted URL that takes them to a targeted Outlook Web App site. An attacker would have no way to force users to visit a specially crafted website. Instead, an attacker would have to convince them to visit the website, typically by getting them to click a link in an instant messenger or email message that takes them to the attacker’s website, and then convince them to click the specially crafted URL.

Revision Note: V1.0 (June 9, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in Microsoft Active Directory Federation Services (AD FS). The vulnerability could allow elevation of privilege if an attacker submits a specially crafted URL to a target site that, due to the vulnerability, fails to properly sanitize script embedded in the URL. Once an attacker has successfully submitted specially crafted script to a target site, any webpage on that site that contains the specially crafted script is a potential vector for cross-site scripting attacks.

Revision Note: V1.0 (June 9, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if Windows Media Player opens specially crafted media content that is hosted on a malicious website. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Revision Note: V1.0 (June 9, 2015): Bulletin published.
Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker places a malicious .dll file in a local directory on the machine or on a network share. An attacker would then have to wait for a user to run a program that can load a malicious .dll file, resulting in elevation of privilege. However, in all cases an attacker would have no way to force a user to visit such a network share or website.

Revision Note: V1.0 (June 9, 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.
