Microsoft Security Bulletin: May 2013 Release!
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 |
|---|---|---|---|---|
| Cumulative Security Update for Internet ExplorerThis 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 ServiceThis 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 SpoofingThis 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 ExecutionThis 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 DisclosureThis 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 DisclosureThis 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.
