Microsoft FAQ (1)

How could an attacker exploit this vulnerability?

An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.
