Microsoft Windows

MS15-061

Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (3057839) 
This security update resolves vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Elevation of Privilege

Requires restart

Microsoft Windows

MS15-062

Vulnerability in Active Directory Federation Services Could Allow Elevation of Privilege (3062577) 
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. Due to the vulnerability, in specific situations specially crafted script is not properly sanitized, which subsequently could lead to an attacker-supplied script being run in the security context of a user who views the malicious content. For cross-site scripting attacks, this vulnerability requires that a user be visiting a compromised site for any malicious action to occur.

Important 
Elevation of Privilege

Does not require restart

Microsoft Windows

MS15-063

Vulnerability in Windows Kernel Could Allow Elevation of Privilege (3063858) 
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.

Important 
Elevation of Privilege

Requires restart

Microsoft Windows

MS15-064

Vulnerabilities in Microsoft Exchange Server Could Allow Elevation of Privilege (3062157) 
This security update resolves vulnerabilities in Microsoft Exchange Server. The most severe of the vulnerabilities could allow elevation of privilege if an authenticated user clicks a link to a specially crafted webpage. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or Instant Messenger message.

Important 
Elevation of Privilege

Does not require restart

Microsoft Exchange Server
