I am running SQL Server on my system. What action do I need to take?
Update your relevant version of SQL Server. Any applicable driver fixes are included in those updates.
Update your application to use Microsoft ODBC Driver 17 (or 18) for SQL Server or Microsoft OLE DB Driver 18 (or 19). Update the drivers to the versions listed on this page, which provide protection against this vulnerability.
Consult with your application vendor if it is compatible with Microsoft ODBC Driver 17 (or 18) for SQL Server or Microsoft OLE DB Driver 18 (or 19). Update the drivers to the versions listed in this page, which provide protection against this vulnerability
First, determine your SQL Server version number. For more information on determining your SQL Server version number, see Microsoft Knowledge Base Article 321185 - How to determine the version, edition, and update level of SQL Server and its components., Second, in the table below, locate your version number or the version range that your version number falls within. The corresponding update is the one you need to install.

The General Distribution Release (GDR) and Cumulative Update (CU) designations correspond to the two different servicing options in place for SQL Server baseline releases. A baseline can be either an RTM release or a Service Pack release.
GDR updates – cumulatively only contain security updates for the given baseline., CU updates – cumulatively contain all functional fixes and security updates for the given baseline.
For any given baseline, either the GDR or CU updates could be options (see below).
If SQL Server installation is at a baseline version, you can choose either the GDR or CU update., If SQL Server installation has intentionally only installed past GDR updates, then choose to install the GDR update package., If SQL Server installation has intentionally installed previous CU updates, then chose to install the CU security update package.
Yes. SQL Server instances on Windows Azure (IaaS) can be offered the security updates through Microsoft Update, or customers can download the security updates from Microsoft Download Center and apply them manually.
