Microsoft patches 11 vulnerabilities

Microsoft released nine security bulletins which include four critical and five important updates to address 11 vulnerabilities affecting Windows, Internet Information Services (IIS) and Microsoft Office.

Microsoft is also releasing two security advisories this month. Security Advisory 2401593 impacts Exchange customers using Outlook Web Access and could allow an elevation of privilege. Security Advisory 973811 updated to enable Outlook Express and Windows Mail to opt in to Extended Protection for authentication.

Vulnerability in Print Spooler Service Could Allow Remote Code Execution
This security update resolves a publicly disclosed vulnerability in the Print Spooler service. The vulnerability could allow remote code execution if an attacker sends a specially crafted print request to a vulnerable system that has a print spooler interface exposed over RPC. By default, printers are not shared on any currently supported Windows operating system.

Vulnerability in MPEG-4 Codec Could Allow Remote Code Execution
This security update resolves a privately reported vulnerability in MPEG-4 codec. The vulnerability could allow remote code execution if a user opens a specially crafted media file or receives specially crafted streaming content from a Web site or any application that delivers Web content. An attacker who successfully exploited this vulnerability could gain the same user rights as the local 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.

Vulnerability in Unicode Scripts Processor Could Allow Remote Code Execution
This security update resolves a privately reported vulnerability in the Unicode Scripts Processor. The vulnerability could allow remote code execution if a user viewed a specially crafted document or Web page with an application that supports embedded OpenType fonts. An attacker who successfully exploited this vulnerability could gain the same user rights as the local 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.

Vulnerability in Microsoft Outlook Could Allow Remote Code Execution
This security update resolves a privately reported vulnerability. The vulnerability could allow remote code execution if a user opened or previewed a specially crafted e-mail message using an affected version of Microsoft Outlook that is connected to an Exchange server with Online Mode. An attacker who successfully exploited this vulnerability could gain the same user rights as the local 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.

Vulnerabilities in Microsoft IIS Could Allow Remote Code Execution
This security update resolves two privately reported vulnerabilities and one publicly disclosed vulnerability in Internet Information Services (IIS). The most severe of these vulnerabilities could allow remote code execution if a client sends a specially crafted HTTP request to the server. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Vulnerability in Remote Procedure Call Could Allow Remote Code Execution
This security update resolves a privately reported vulnerability in Microsoft Windows. This security update is rated Important for all supported editions of Windows XP and Windows Server 2003. All supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 are not affected by the vulnerability.

The vulnerability could allow remote code execution if an attacker sent a specially crafted RPC response to a client-initiated RPC request. An attacker who successfully exploited this vulnerability could execute arbitrary code and take complete control of an affected system. An attacker must convince the user to initiate an RPC connection to a malicious server under the attacker’s control. An attacker could not remotely exploit this vulnerability without user interaction.

Vulnerability in WordPad Text Converters Could Allow Remote Code Execution
This security update resolves a privately reported vulnerability in Microsoft Windows. This security update is rated Important for all supported editions of Windows XP and Windows Server 2003. All supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 are not affected by the vulnerability.

The vulnerability could allow remote code execution if a user opened a specially crafted file using WordPad. An attacker who successfully exploited this vulnerability could gain the same user rights as the local 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.

Vulnerability in Local Security Authority Subsystem Service Could Allow Elevation of Privilege
This security update resolves a privately reported vulnerability in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS). The vulnerability could allow elevation of privilege if an authenticated attacker sent specially crafted Lightweight Directory Access Protocol (LDAP) messages to a listening LSASS server. In order to successfully exploit this vulnerability, an attacker must have a member account within the target Windows domain. However, the attacker does not need to have a workstation joined to the Windows domain.

Vulnerability in Windows Client/Server Runtime Subsystem Could Allow Elevation of Privilege
This security update resolves a privately reported vulnerability in Microsoft Windows. This security update is rated Important for all supported editions of Windows XP and Windows Server 2003. All supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 are not affected by the vulnerability.

The vulnerability could allow elevation of privilege if an attacker logged on to an affected system that is configured with a Chinese, Japanese, or Korean system locale. An attacker who successfully exploited this vulnerability could then install programs; view, change, or delete data; or create new accounts with full user rights.
