Revision Note: V1.3 (September 24, 2014): Bulletin revised to correct a missing Server Core installation entry in the Affected Software table for Microsoft .NET Framework 4 when installed on Windows Server 2008 R2 for x64-based Systems Service Pack 1 (2898855). This is an informational change only. Customers running this affected software on Server Core installations who have already applied the 2898855 update do not need to take any action. Customers running this affected software on Server Core installations who have not already installed the update should do so to be protected from the vulnerabilities addressed in this bulletin.
