Bulletin Information

The following table summarizes the security bulletins for this month in order of severity.

For details on affected software, see the next section, Affected Software and Download Locations.

Bulletin IDBulletin Title and Executive SummaryMaximum Severity Rating and Vulnerability ImpactRestart RequirementAffected Software
MS11-083 Vulnerability in TCP/IP Could Allow Remote Code Execution (2588516) 

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker sends a continuous flow of specially crafted UDP packets to a closed port on a target system.
Critical 
Remote Code Execution
Requires restartMicrosoft Windows
MS11-085 Vulnerability in Windows Mail and Windows Meeting Space Could Allow Remote Code Execution (2620704) 

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate file (such as an .eml or .wcinv file) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Then, while opening the legitimate file, Windows Mail or Windows Meeting Space could attempt to load the DLL file and execute any code it contained. For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open a legitimate file (such as an .eml or .wcinv file) from this location that is then loaded by a vulnerable application.
Important 
Remote Code Execution
May require restartMicrosoft Windows
MS11-086 Vulnerability in Active Directory Could Allow Elevation of Privilege (2630837) 

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 Active Directory is configured to use LDAP over SSL (LDAPS) and an attacker acquires a revoked certificate that is associated with a valid domain account and then uses that revoked certificate to authenticate to the Active Directory domain. By default, Active Directory is not configured to use LDAP over SSL.
Important 
Elevation of Privilege
Requires restartMicrosoft Windows
MS11-084 Vulnerability in Windows Kernel-Mode Drivers Could Allow Denial of Service (2617657) 

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if a user opens a specially crafted TrueType font file as an e-mail attachment or navigates to a network share or WebDAV location containing a specially crafted TrueType font file. For an attack to be successful, a user must visit the untrusted remote file system location or WebDAV share containing the specially crafted TrueType font file, or open the file as an e-mail attachment. In all cases, however, an attacker would have no way to force users to perform these actions. Instead, an attacker would have to persuade users to do so, typically by getting them to click a link in an e-mail message or Instant Messenger message.
Moderate 
Denial of Service
Requires restartMicrosoft Windows
