However, it could be possible for an attacker to introduce such a packet in order to initiate an exchange, which would thereafter be self-sustaining. Once you have installed the Application Center version of MSDE Service Pack 2, you should install the SQL Server 2000 security patch. Specifically, the patch changes the operation of SQL Server to restrict unprivileged users to only performing queries against SQL Server data. How does the patch eliminate the vulnerability? The patch eliminates the current keep-alive mechanism, and determines which servers are active and which are passive via a different mechanism. Source

Thus, although the attacker's code could take any desired action on the database, it would not necessarily have significant privileges at the operating system level if best practices have been followed.

This is a new variant of a vulnerability originally reported in Microsoft Security Bulletin MS02-038.

DBCC's are utility programs provided as part of SQL Server 2000. By sending a carefully crafted packet to the Resolution Service, an attacker could cause portions of system memory (the heap in one case, the stack in the other) to be overwritten. However, while the patch was fully effective in eliminating the security vulnerability, in October, 2002, it was found to interfere with SQL Server operations under some circumstances. This creates a situation in which an unprivileged user could submit a job that would create a file containing valid operating system commands in another user's Startup folder, or simply overwrite
