Microsoft Security Bulletin MS11-068 MS11-068 - Moderate : Vulnerability in Windows Kernel Could Allow Denial of Service (2556532) - Version: 1.1 Severity Rating: Moderate Revision Note: V1.1 (August 10, 2011): Revised the Server Core installation not affected notation for Windows Server 2008 and Windows Server 2008 R2 to clarify that the update will still be offered to systems installed using the Server Core installation option. Summary: This security update resolves a publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow denial of service if a user visits a network share (or visits a Web site that points to a network share) containing a specially crafted file. In all cases, however, an attacker would have no way to force a user to visit such a network share or Web site. Instead, an attacker would have to convince a user to do so, typically by getting the user to click a link in an e-mail message or Instant Messenger message.Release Date:2011-08-10
