Bulletin ID Maximum Severity Rating and Vulnerability Impact Restart Requirement Affected Software
MS12-064 Critical
Remote Code Execution
May require restart Microsoft Office, Microsoft Server Software
Vulnerabilities in Microsoft Word Could Allow Remote Code Execution (2742319)
This security update resolves two privately reported vulnerabilities in Microsoft Office. The more severe vulnerability could allow remote code execution if a user opens or previews a specially crafted RTF file. 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.
MS12-065 Important< br/>Remote Code Execution May require restart Microsoft Office
Vulnerability in Microsoft Works Could Allow Remote Code Execution (2754670)

This security update resolves a privately reported vulnerability in Microsoft Works. The vulnerability could allow remote code execution if a user opens a specially crafted Microsoft Word file using Microsoft Works. 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.

MS12-066 Important
Elevation of Privilege
May require restart Microsoft Office,
Microsoft Server Software,
Microsoft Lync
Vulnerability in HTML Sanitization Component Could Allow Elevation of Privilege (2741517)

This security update resolves a publicly disclosed vulnerability in Microsoft Office, Microsoft Communications Platforms, Microsoft Server software, and Microsoft Office Web Apps. The vulnerability could allow elevation of privilege if an attacker sends specially crafted content to a user.

MS12-067 Important
Remote Code Execution
May require restart Microsoft Office, Microsoft Server Software
Vulnerabilities in FAST Search Server 2010 for SharePoint Parsing Could Allow Remote Code Execution (2742321)
This security update resolves publicly disclosed vulnerabilities in Microsoft FAST Search Server 2010 for SharePoint. The vulnerabilities could allow remote code execution in the security context of a user account with a restricted token. FAST Search Server for SharePoint is only affected by this issue when Advanced Filter Pack is enabled. By default, Advanced Filter Pack is disabled.
MS12-068 Important
Elevation of Privilege
Requires restart Microsoft Windows
Vulnerability in Windows Kernel Could Allow Elevation of Privilege (2724197)This security update resolves a privately reported vulnerability in all supported releases of Microsoft Windows except Windows 8 and Windows Server 2012. This security update is rated Important for all supported editions of Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2.

The vulnerability could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.

MS12-069 Important
Denial of Service
Requires restart Microsoft Windows
Vulnerability in Kerberos Could Allow Denial of Service (2743555)
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if a remote attacker sends a specially crafted session request to the Kerberos server. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.
MS12-070 Important
Elevation of Privilege
May require restart Microsoft SQL Server
Vulnerability in SQL Server Could Allow Elevation of Privilege (2754849)
This security update resolves a privately reported vulnerability in Microsoft SQL Server on systems running SQL Server Reporting Services (SSRS). The vulnerability is a cross-site-scripting (XSS) vulnerability that could allow elevation of privilege, enabling an attacker to execute arbitrary commands on the SSRS site in the context of the targeted user. An attacker could exploit this vulnerability by sending a specially crafted link to the user and convincing the user to click the link. An attacker could also host a website that contains a webpage designed to exploit the vulnerability. In addition, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability.

In summary, we are likely to see updates requiring reboots of servers this month. As usual, as a UKFast customer, you will benefit from these updates being applied automatically unless you have opted out of this service.
