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.
How could an attacker successfully exploit this vulnerability?
An Out Of Bounds Write Vulnerability exists in the SQLcmd tool that could be leveraged by an unauthenticated attacker to achieve remote code execution. However, since only outdated versions of the library are vulnerable, and the attacker cannot consistently trigger the bytes of memory to be overwritten, this results in a low confidentiality, integrity and availability rating.
