This is a cumulative patch that includes the functionality of all previously released patches for SQL Server 7.0, SQL Server 2000, MSDE 1.0, and MSDE 2000. In addition, it eliminates three newly discovered vulnerabilities.
A flaw exists in the checking method for the named pipe that could allow an attacker local to the system running SQL Server to hijack (gain control of) the named pipe during another client's authenticated logon password. This would allow the attacker to gain control of the named pipe at the same permission level as the user who is attempting to connect. If the user who is attempting to connect remotely has a higher level of permissions than the attacker, the attacker will assume those rights when the named pipe is compromised.
This vulnerability would not allow an attacker to run arbitrary code or elevate their permissions, but it may still be possible for a denial of service condition to exist that would require that the server be restarted to restore functionality.
Named Pipe Hijacking: - To exploit this flaw, the attacker would need to be an authenticated user local to the system. - This vulnerability provides no way for an attacker to remotely usurp control over the named pipe.
Named Pipe Denial of Service: - Although it is unnecessary that the attacker be authenticated, to exploit this flaw the attacker would require access to the local intranet. - Restarting the SQL Server Service will reinstate normal operations - This flaw provides no method by which an attacker can gain access to the system or information contained in the database.
SQL Server Buffer Overrun: - To exploit this flaw, the attacker would need to be an authenticated user local to the system. - This vulnerability cannot be remotely exploited.
