MS11-002

Vulnerabilities in Microsoft Data Access Components Could Allow Remote Code Execution (2451910)

This security update resolves two privately reported vulnerabilities in Microsoft Data Access Components. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page. 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.

Remote Code Execution

MS11-001

Vulnerability in Windows Backup Manager Could Allow Remote Code Execution (2478935)

This security update resolves a publicly disclosed vulnerability in Windows Backup Manager. The vulnerability could allow remote code execution if a user opens a legitimate Windows Backup Manager file that is located in the same network directory as a specially crafted library file. For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open the legitimate file from that location, which in turn could cause Windows Backup Manager to load the specially crafted library file.

MS11-003

Cumulative Security Update for Internet Explorer (2482017)

This security update resolves two privately reported vulnerabilities and two publicly disclosed vulnerabilities in Internet Explorer. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer or if a user opens a legitimate HTML file that loads a specially crafted library file. An attacker who successfully exploited any of these vulnerabilities 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.

MS11-006

Vulnerability in Windows Shell Graphics Processing Could Allow Remote Code Execution (2483185)

This security update resolves a publicly disclosed vulnerability in the Windows Shell graphics processor. The vulnerability could allow remote code execution if a user views a specially crafted thumbnail image. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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.

MS11-007

Vulnerability in the OpenType Compact Font Format (CFF) Driver Could Allow Remote Code Execution (2485376)

This security update resolves a privately reported vulnerability in the Windows OpenType Compact Font Format (CFF) driver. The vulnerability could allow remote code execution if a user views content rendered in a specially crafted CFF font. In all cases, an attacker would have no way to force users to view the specially crafted content. Instead, an attacker would have to convince users to visit a Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.

Critical
Remote Code Execution

MS11-004

Vulnerability in Internet Information Services (IIS) FTP Service Could Allow Remote Code Execution (2489256)

This security update resolves a publicly disclosed vulnerability in Microsoft Internet Information Services (IIS) FTP Service. The vulnerability could allow remote code execution if an FTP server receives a specially crafted FTP command. FTP Service is not installed by default on IIS.

Important

MS11-005

Vulnerability in Active Directory Could Allow Denial of Service (2478953)

This security update resolves a publicly disclosed vulnerability in Active Directory. The vulnerability could allow denial of service if an attacker sent a specially crafted packet to an affected Active Directory server. The attacker must have valid local administrator privileges on the domain-joined computer in order to exploit this vulnerability.

Important
Denial of Service

MS11-008

Vulnerabilities in Microsoft Visio Could Allow Remote Code Execution (2451879)

This security update resolves two privately reported vulnerabilities in Microsoft Visio. The vulnerabilities could allow remote code execution if a user opens a specially crafted Visio file. An attacker who successfully exploited either of these vulnerabilities could gain the same user rights as the logged-on 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.

MS11-009

Vulnerability in JScript and VBScript Scripting Engines Could Allow Information Disclosure (2475792)

This security update resolves a privately reported vulnerability in the JScript and VBScript scripting engines. The vulnerability could allow information disclosure if a user visited a specially crafted Web site. An attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.

MS11-010

Vulnerability in Windows Client/Server Run-time Subsystem Could Allow Elevation of Privilege (2476687)

This security update resolves a privately reported vulnerability in the Microsoft Windows Client/Server Run-time Subsystem (CSRSS) in Windows XP and Windows Server 2003.

The vulnerability could allow elevation of privilege if an attacker logs on to a user's system and starts a specially crafted application that continues running after the attacker logs off in order to obtain the logon credentials of subsequent users. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.
