I’m a little late with this one but here it is anyway.  Check out this months updates and apply where needed in your environments.  You can also check out the Security bulletin webcast if you need more specifics about these patches.

Bulletin ID Bulletin Title and Executive Summary Maximum Severity Rating and Vulnerability Impact Restart Requirement Affected Software
MS13-059 Cumulative Security Update for Internet Explorer (2862772)

This security update resolves eleven privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the most severe of these vulnerabilities could gain the same user rights as the current user. 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.
Critical 
Remote Code Execution
Requires restart Microsoft Windows,
Internet Explorer
MS13-060 Vulnerability in Unicode Scripts Processor Could Allow Remote Code Execution (2850869)

This security update resolves a privately reported vulnerability in the Unicode Scripts Processor included in Microsoft Windows. The vulnerability could allow remote code execution if a user viewed a specially crafted document or webpage with an application that supports embedded OpenType fonts. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. 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.
Critical 
Remote Code Execution
May require restart Microsoft Windows
MS13-061 Vulnerabilities in Microsoft Exchange Server Could Allow Remote Code Execution (2876063)

This security update resolves three publicly disclosed vulnerabilities in Microsoft Exchange Server. The vulnerabilities exist in the WebReady Document Viewing and Data Loss Prevention features of Microsoft Exchange Server. The vulnerabilities could allow remote code execution in the security context of the transcoding service on the Exchange server if a user previews a specially crafted file using Outlook Web App (OWA). The transcoding service in Exchange that is used for WebReady Document Viewing uses the credentials of the LocalService account. The Data Loss Prevention feature hosts code that could allow remote code execution in the security context of the Filtering Management service if a specially crafted message is received by the Exchange server. The Filtering Management service in Exchange uses the credentials of the LocalService account. The LocalService account has minimum privileges on the local system and presents anonymous credentials on the network.
Critical 
Remote Code Execution
May require restart Microsoft Server Software
MS13-062 Vulnerability in Remote Procedure Call Could Allow Elevation of Privilege (2849470)

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker sends a specially crafted RPC request.
Important 
Elevation of Privilege
Requires restart Microsoft Windows
MS13-063 Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege (2859537)

This security update resolves one publicly disclosed vulnerability and three privately reported vulnerabilities in Microsoft Windows. The most severe vulnerabilities could allow elevation of privilege if an attacker logged on locally and ran a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit these vulnerabilities. The vulnerabilities could not be exploited remotely or by anonymous users.
Important 
Elevation of Privilege
Requires restart Microsoft Windows
MS13-064 Vulnerability in Windows NAT Driver Could Allow Denial of Service (2849568)

This security update resolves a privately reported vulnerability in the Windows NAT Driver in Microsoft Windows. The vulnerability could allow denial of service if an attacker sends a specially crafted ICMP packet to a target server that is running the Windows NAT Driver service.
Important 
Denial of Service
Requires restart Microsoft Windows
MS13-065 Vulnerability in ICMPv6 could allow Denial of Service (2868623)

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow a denial of service if the attacker sends a specially crafted ICMP packet to the target system.
Important 
Denial of Service
Requires restart Microsoft Windows
MS13-066 Vulnerability in Active Directory Federation Services Could Allow Information Disclosure (2873872) 

This security update resolves a privately reported vulnerability in Active Directory Federation Services (AD FS). The vulnerability could reveal information pertaining to the service account used by AD FS. An attacker could then attempt logons from outside the corporate network, which would result in account lockout of the service account used by AD FS if an account lockout policy has been configured. This would result in denial of service for all applications relying on the AD FS instance.
Important 
Information Disclosure
May require restart Microsoft Windows
