Microsoft's May 2014 Patch Load

Microsoft released it's May 2014 Security Update Tuesday. The latest vulnerabilities to be addressed affect everything from Windows, Internet Explorer and Office to Microsoft Server Software, Productivity Software and the .NET Framework.

What follows is the full breakdown of bulletins.

MS14-021
(Released out-of-band on May 1, 2014)
Security Update for Internet Explorer (2965111)
This security update resolves a publicly disclosed vulnerability in Internet Explorer. The vulnerability could allow remote code execution if a user views a specially crafted webpage using an affected version of 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
Requires restart
Microsoft Windows,
Internet Explorer

MS14-022
Vulnerabilities in Microsoft SharePoint Server Could Allow Remote Code Execution (2952166)
This security update resolves multiple privately reported vulnerabilities in Microsoft Office server and productivity software. The most severe of these vulnerabilities could allow remote code execution if an authenticated attacker sends specially crafted page content to a target SharePoint server.
**Critical**
Remote Code Execution
May require restart
Microsoft Server Software,
Productivity Software

MS14-023
Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2961037)
This security update resolves two privately reported vulnerabilities in Microsoft Office. The most severe vulnerability could allow remote code execution if a user opens an Office file that is located in the same network directory as a specially crafted library file. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
**Important**
Remote Code Execution
May require restart
Microsoft Office

MS14-024
Vulnerability in a Microsoft Common Control Could Allow Security Feature Bypass (2961033)
This security update resolves one privately reported vulnerability in an implementation of the MSCOMCTL common controls library. The vulnerability could allow security feature bypass if a user views a specially crafted webpage in a web browser capable of instantiating COM components, such as Internet Explorer. In a web-browsing attack scenario, an attacker who successfully exploited this vulnerability could bypass the Address Space Layout Randomization (ASLR) security feature, which helps protect users from a broad class of vulnerabilities. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use this ASLR bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability that could take advantage of the ASLR bypass to run arbitrary code.
**Important**
Security Feature Bypass
May require restart
Microsoft Office

MS14-025
Vulnerability in Group Policy Preferences Could Allow Elevation of Privilege (2962486)
This security update resolves a publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if Active Directory Group Policy preferences are used to distribute passwords across the domain - a practice that could allow an attacker to retrieve and decrypt the password stored with Group Policy preferences.
**Important**
Elevation of Privilege
May require restart
Microsoft Windows

MS14-026
Vulnerability in .NET Framework Could Allow Elevation of Privilege (2958732)
This security update resolves a privately reported vulnerability in Microsoft .NET Framework. The vulnerability could allow elevation of privilege if an unauthenticated attacker sends specially crafted data to an affected workstation or server that uses .NET Remoting. .NET Remoting is not widely used by applications; only custom applications that have been specifically designed to use .NET Remoting would expose a system to the vulnerability.
**Important**
Elevation of Privilege
May require restart
Microsoft Windows,
Microsoft .NET Framework

MS14-027
Vulnerability in Windows Shell Handler Could Allow Elevation of Privilege (2962488)
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker runs a specially crafted application that uses ShellExecute. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
**Important**
Elevation of Privilege
Requires restart
Microsoft Windows

MS14-028
Vulnerability in iSCSI Could Allow Denial of Service (2962485)
This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow denial of service if an attacker sends large amounts of specially crafted iSCSI packets over the target network. This vulnerability only affects servers for which the iSCSI target role has been enabled.
**Important**
Denial of Service
May require restart
Microsoft Windows

MS14-029
Security Update for Internet Explorer (2962482)
This security update resolves two privately reported vulnerabilities in Internet Explorer. The 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. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
**Critical**
Remote Code Execution
Requires restart
Microsoft Windows,
Internet Explorer
