Overview
Microsoft SQL Server ships with several administrative tools that allow database users to elevate their administrative privileges from a single database to all databases on the server.
Description
| Microsoft SQL Server ships with several utilities known as Database Consistency Checkers (DBCCs). According to Microsoft Security Bulletin MS02-038, "DBCCs are command console utilities that allow maintenance and other operations to be performed on a SQL server." An unspecified subset of the DBCC utilities contain buffer overflows that allow users who have db_owner or db_ddladmin privileges on a single database to elevate their administrative privileges to the entire SQL server. | 
Impact
| This vulnerability allows remote attackers to execute arbitrary code with the privileges of the SQL service account. If the privileges of the service account are elevated via VU#796313, this vulnerability may result in compromise of the server host. | 
Solution
| Apply a patch Microsoft has published Security Bulletin MS02-038 to address this vulnerability.  For more information, please see |
