SQL Server 2016 SP2 CU6: The Update with Significant Changes and Important Security Updates

Microsoft has announced the release of SQL Server 2016 Service Pack 2 Cumulative Update 6 (CU6), and it promises to be an update that you’ll remember forever. This update contains important bug fixes and improvements to SQL Server 2016 SP2.

SQL Server 2016 SP2 CU6 includes over 50 bug fixes, including fixes for issues related to Always On availability groups, database backup and restore, and more. This update also includes important security updates and improvements.

One of the most significant changes in this update is the removal of support for the remote query timeout option. This change was made to address a security vulnerability that could allow a remote attacker to execute a denial of service (DoS) attack on SQL Server by sending a specially crafted query. Microsoft recommends that you update your applications to use the query timeout options that are available in your application frameworks.

As always, it is highly recommended that you test this update in a non-production environment before deploying it to your production systems. You can download the update from the Microsoft Download Center or install it using the SQL Server Update Manager.
