Microsoft SQL Server is prone to a remote memory-corruption vulnerability because it fails to perform adequate boundary checks on user-supplied input.
Authenticated attackers can exploit this issue to execute arbitrary code and completely compromise affected computers. Failed attacks will likely cause denial-of-service conditions.

Disallow anonymous access to services. Permit access for trusted individuals only.
Permitting access only for trusted individuals will greatly reduce the likelihood of attacks.
Run all software as a nonprivileged user with minimal access rights.
To mitigate the impact of a successful exploit, run the affected application as a user with minimal access rights.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.
Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploit attempts of memory-corruption vulnerabilities.
