The following table summarizes the security bulletins for this month in order of severity.

For details on affected software, see the next section, Affected Software and Download Locations.

Bulletin IDBulletin Title and Executive SummaryMaximum Severity Rating and Vulnerability ImpactRestart RequirementAffected Software
MS12-029 Vulnerability in Microsoft Word Could Allow Remote Code Execution (2680352) 

This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted RTF file. An attacker who successfully exploited the 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

MS12-034 Combined Security Update for Microsoft Office, Windows, .NET Framework, and Silverlight (2681578) 

This security update resolves three publicly disclosed vulnerabilities and seven privately reported vulnerabilities in Microsoft Office, Microsoft Windows, the Microsoft .NET Framework, and Microsoft Silverlight. The most severe of these vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a malicious webpage that embeds TrueType font files. An attacker would have no way to force users to visit a malicious website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website.
