Any applicable driver fixes are included in those updates. **There are GDR and/or CU (Cumulative Update) updates offered for my version of SQL Server. How do I know which update to use?** * 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. **Note** If your SQL Server version number is not represented in the table below, your SQL Server version is no longer supported. Please upgrade to the latest Service Pack or SQL Server product in order to apply this and future security updates. Update Numb...

**According to the CVSS metric, user interaction is required (UI:R) and privileges required is Low (PR:L). What does that mean for this vulnerability?** An authorized attacker with low privileges creates a scheduled task that is set to run when a user logs on and spoofs interfaces that belong to many services so the victim can connect to the attacker's server instead of the original.
