This security update resolves thirteen 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 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
MS13-010 Vulnerability in Vector Markup Language Could Allow Remote Code Execution (2797052) 

This security update resolves a privately reported vulnerability in the Microsoft implementation of Vector Markup Language (VML). The vulnerability could allow remote code execution if a user viewed a specially crafted webpage using Internet Explorer. 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, 
Internet Explorer
MS13-011 Vulnerability in Media Decompression Could Allow Remote Code Execution (2780091) 

This security update resolves one publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a specially crafted media file (such as an .mpg file), opens a Microsoft Office document (such as a .ppt file) that contains a specially crafted embedded media file, or receives specially crafted streaming content. 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
MS13-012 Vulnerabilities in Microsoft Exchange Server Could Allow Remote Code Execution (2809279) 

This security update resolves publicly disclosed vulnerabilities in Microsoft Exchange Server. The most severe vulnerability is in Microsoft Exchange Server WebReady Document Viewing, and 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 is running in the LocalService account. The LocalService account has minimum privileges on the local computer and presents anonymous credentials on the network.

This security update resolves a privately reported vulnerability in Microsoft Windows Object Linking and Embedding (OLE) Automation. The vulnerability could allow remote code execution if a user opens a specially crafted 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
Requires restart Microsoft Windows
MS13-013 Vulnerabilities in FAST Search Server 2010 for SharePoint Parsing Could Allow Remote Code Execution (2784242) 

This security update resolves publicly disclosed vulnerabilities in Microsoft FAST Search Server 2010 for SharePoint.

Important 
Denial of Service
Requires restart Microsoft Windows
MS13-015 Vulnerability in .NET Framework Could Allow Elevation of Privilege (2800277) 

This security update resolves one privately reported vulnerabilityin the .NET Framework. The vulnerability could allow elevation of privilege if a user views a specially crafted webpage using a web browser that can run XAML Browser Applications (XBAPs). The vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions. 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.
Important
