**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. **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 following table, 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 to apply this and future security updates. Update Number T...

Buffer over-read in Microsoft Office Excel allows an unauthorized attacker to disclose information over an adjacent network.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**How could an attacker exploit the vulnerability?** An authorized attacker could inject SQL code and run it with elevated privileges at table creation.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** In this case, a successful attack could be performed from a low privilege Hyper-V guest. The attacker could traverse the guest's security boundary to execute code on the Hyper-V host execution environment.
