Buffer overflow in the convert function in Microsoft SQL Server 2000 SP4, 2000 Desktop Engine (MSDE 2000) SP4, and 2000 Desktop Engine (WMSDE) allows remote authenticated users to execute arbitrary code via a crafted SQL expression.

Microsoft SQL Server 7, 2000, and MSDE allows local users to gain privileges by hijacking a named pipe during the authentication of another user, aka the "Named Pipe Hijacking" vulnerability.

Microsoft SQL Server 7, 2000, and MSDE allows local or remote authenticated users to cause a denial of service (crash or hang) via a long request to a named pipe.

Microsoft SQL Server 7, 2000, and MSDE allows local users to execute arbitrary code via a certain request to the Local Procedure Calls (LPC) port that leads to a buffer overflow.

Microsoft SQL Server 6.0 through 2000, with SQL Authentication enabled, uses weak password encryption (XOR), which allows remote attackers to sniff and decrypt the password.

Microsoft SQL Server 2000 through SQL Server 2000 SP2 allows the "public" role to execute the (1) sp_MSSetServerProperties or (2) sp_MSsetalertinfo stored procedures, which allows attackers to modify configuration including SQL server startup and alert settings.

The xp_runwebtask stored procedure in the Web Tasks component of Microsoft SQL Server 7.0 and 2000, Microsoft Data Engine (MSDE) 1.0, and Microsoft Desktop Engine (MSDE) 2000 can be executed by PUBLIC, which allows an attacker to gain privileges by updating a webtask that is owned by the database owner through the msdb.dbo.mswebtasks table, which does not have strong permissions.

Microsoft SQL Server 7.0 and 2000, including Microsoft Data Engine (MSDE) 1.0 and Microsoft Desktop Engine (MSDE) 2000, writes output files for scheduled jobs under its own privileges instead of the entity that launched it, which allows attackers to overwrite system files, aka "Flaw in Output File Handling for Scheduled Jobs."

Buffer overflow in the Database Console Command (DBCC) that handles user inputs in Microsoft SQL Server 7.0 and 2000, including Microsoft Data Engine (MSDE) 1.0 and Microsoft Desktop Engine (MSDE) 2000, allows attackers to execute arbitrary code via a long SourceDB argument in a "non-SQL OLEDB data source" such as FoxPro, a variant of CAN-2002-0644.

Microsoft SQL Server 2000 SP2, when configured as a distributor, allows attackers to execute arbitrary code via the @scriptfile parameter to the sp_MScopyscript stored procedure.
