Welcome to another security bulletin release.  This month we have 10 security bulletin updates plus a firmware update for Surface RT and Surface Pro.  The great thing about the new Surface Pro firmware update is we now support PXE booting with the Surface Pro Ethernet adapter.  This will be great for enterprises to get a custom image on the device!  Below is a table that outlines this month’s bulletins.

Bulletin ID

Bulletin Title and Executive Summary

Maximum Severity Rating & Vulnerability Impact Restart Requirement Affected Software

MS13-037

Cumulative Security Update for Internet Explorer

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
MS13-038 Security Update for Internet Explorer

This security update resolves one publicly disclosed vulnerability in Internet Explorer. The vulnerability could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. 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,
Internet Explorer
MS13-039 Vulnerability in HTTP.sys Could Allow Denial of Service

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if an attacker sends a specially crafted HTTP packet to an affected Windows server or client.
Important 
Denial of Service
Requires restart Microsoft Windows
MS13-040 Vulnerabilities in .NET Framework Could Allow Spoofing

This security update resolves one privately reported vulnerability and one publicly disclosed vulnerability in the .NET Framework. The more severe of the vulnerabilities could allow spoofing if a .NET application receives a specially crafted XML file. An attacker who successfully exploited the vulnerabilities could modify the contents of an XML file without invalidating the file's signature and could gain access to endpoint functions as if they were an authenticated user.
Important 
Spoofing
May require restart Microsoft Windows,
Microsoft .NET Framework
MS13-041 Vulnerability in Lync Could Allow Remote Code Execution

This security update resolves a privately reported vulnerability in Microsoft Lync. The vulnerability could allow remote code execution if an attacker shares specially crafted content, such as a file or program, as a presentation in Lync or Communicator and then convinces a user to accept an invitation to view or share the presentable content. In all cases, an attacker would have no way to force users to view or share the attacker-controlled file or program. Instead, an attacker would have to convince users to take action, typically by getting them to accept an invitation in Lync or Communicator to view or share the presentable content.
Important 
Remote Code Execution
May require restart Microsoft Lync
MS13-042 Vulnerabilities in Microsoft Publisher Could Allow Remote Code Execution

This security update resolves eleven privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user open a specially crafted Publisher file with an affected version of Microsoft Publisher. 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.
Important 
Remote Code Execution
May require restart Microsoft Office
MS13-043 Vulnerability in Microsoft Word Could Allow Remote Code Execution

This security update resolves one privately reported vulnerability in Microsoft Office. The vulnerability could allow code execution if a user opens a specially crafted file or previews a specially crafted email message in an affected version of Microsoft Office software. 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.
Important 
Remote Code Execution
May require restart Microsoft Office
MS13-044 Vulnerability in Microsoft Visio Could Allow Information Disclosure

This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow information disclosure if a user opens a specially crafted Visio file. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to produce information that could be used to try to further compromise an affected system.
Important 
Information Disclosure
May require restart Microsoft Office
MS13-045 Vulnerability in Windows Essentials Could Allow Information Disclosure

This security update resolves a privately reported vulnerability in Windows Essentials. The vulnerability could allow information disclosure if a user opens Windows Writer using a specially crafted URL. An attacker who successfully exploited the vulnerability could override Windows Writer proxy settings and overwrite files accessible to the user on the target system. In a web-based attack scenario, a website could contain a specially crafted link that is used to exploit this vulnerability. An attacker would have to convince users to visit the website and open the specially crafted link.
Important 
Information Disclosure
May require restart Microsoft Windows Essentials
MS13-046 Vulnerabilities in Kernel-Mode Drivers Could Allow Elevation Of Privilege

This security update resolves three privately reported vulnerabilities in Microsoft Windows. The vulnerabilities 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 these vulnerabilities.
Important 
Elevation of Privilege
Requires restart Microsoft Windows

That’s about it guys.  Make sure you apply these updates where appropriate.
