Cumulative Update 6 for SQL Server 2014 SP2

Se aplica a: SQL Server 2014 StandardSQL Server 2014 DeveloperSQL Server 2014 Enterprise Core

Cumulative Update 6 (CU6) for Microsoft SQL Server 2014 Service Pack 2 (SP2) was also released as a SQL Server Security Bulletin on 8/8/2017 (KB 4036996). See CVE-2017-8516 for more information. Because of this, you may already have CU6 installed as part of that security bulletin release, and installation of this CU is unnecessary. If you do try to install CU6 after CVE-2017-8516, you may receive the following message:

There are no SQL Server instances or shared features that can be updated on this computer

This indicates that CU6 is already installed and no further action is required.

Note The package name for CU6, "SQLServer2014SP2-KB4019094-<x86/x64>.exe", contains the CVE-2017-8516 KB number (4036996), not the CU6 KB number (4019094). This can be ignored as a single package services both release channels.

This article describes cumulative update package 6 (build number: 12.0.5553.0) for SQL Server 2014 SP2. This update contains fixes that were released after the release of SQL Server 2014 SP2.

Cumulative update

Cumulative updates (CU) are now available at the Microsoft Download Center.

Only the most recent CU that was released for SQL Server 2014 SP2 is available at the Download Center.
  • Each new CU contains all the fixes that were included with the previous CU for the installed version/Service Pack of SQL Server.
  • Microsoft recommends ongoing, proactive installation of CUs as they become available:
    • SQL Server CUs are certified to the same levels as Service Packs, and should be installed at the same level of confidence.
    • Historical data shows that a significant number of support cases involve an issue that has already been addressed in a released CU.
    • CUs may contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.
  • Just as for SQL Server service packs, we recommend that you test CUs before you deploy them to production environments.
  • We recommend that you upgrade your SQL Server installation to the latest SQL Server 2014 service pack.
