Vulnerability Note VU#484891
Microsoft SQL Server 2000 contains stack buffer overflow in SQL Server Resolution Service
Microsoft SQL Server 2000 contains a remotely exploitable stack buffer overflow that allows attackers to execute arbitrary code with the same privileges as the SQL server.
The SQL Server Resolution Service (SSRS) was introduced in Microsoft SQL Server 2000 to provide referral services for multiple server instances running on the same machine. The service listens for requests on UDP port 1434 and returns the IP address and port number of the SQL server instance that provides access to the requested database.
The SSRS contains a stack buffer overflow that allows an attacker to execute arbitrary code by sending a crafted request to port 1434/udp. The code within such a request will be executed by the server host with the privileges of the SQL Server service account.
This vulnerability allows unauthenticated 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.
