This is a cumulative patch that includes the functionality of all
previously released patches for SQL Server 7.0 and SQL Server 2000.
In addition, it eliminates a newly discovered vulnerability.

SQL Server 7.0 and SQL Server 2000 provide for extended stored
procedures, which are external routines written in programming
languages such as C or C#.

These procedures appear as normal stored procedures to users and can
be invoked and executed just like normal stored procedures. By
default, SQL Server 7.0 and SQL Server 2000 ship with a number of
extended stored procedures which are used for various helper
functions.

Some of the Microsoft-provided extended stored procedures that have
the ability to reconnect to the database as the SQL Server service
account have a flaw in common - namely, they have weak permissions
that can allow nonprivileged users to execute them. Because these
extended stored procedures can be made to run with administrator
privileges on the database, it is thus possible for a nonprivileged
user to run stored procedures on the database with administrator
privileges.

An attacker could exploit this vulnerability in one of two ways. The
attacker could attempt to load and execute a database query that
calls one of the affected extended store procedures. Alternately,
if a web-site or other database front-end were configured to access
and process arbitrary queries, it could be possible for the attacker
to provide inputs that would cause the query to call one of the
functions in question with the appropriate malformed parameters.
