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 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 gain privileges by hijacking a named pipe during the authentication of another user, aka the "Named Pipe Hijacking" vulnerability.

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.

Microsoft SQL Server 7.0 and 2000 installs with weak permissions for extended stored procedures that are associated with helper functions, which could allow unprivileged users, and possibly remote attackers, to run stored procedures with administrator privileges via (1) xp_execresultset, (2) xp_printstatements, or (3) xp_displayparamstmt.

Microsoft SQL Server 2000 allows remote attackers to cause a denial of service via a malformed 0x08 packet that is missing a colon separator.

Buffer overflow in the OpenDataSource function of the Jet engine on Microsoft SQL Server 2000 allows remote attackers to execute arbitrary code.

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.

Buffer overflow in the authentication function for Microsoft SQL Server 2000 and Microsoft Desktop Engine (MSDE) 2000 allows remote attackers to execute arbitrary code via a long request to TCP port 1433, aka the "Hello" overflow.

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 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."

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 7.0 server allows a remote attacker to cause a denial of service via a malformed TDS packet.

Microsoft SQL Server 6.5 uses weak encryption for the password for the SQLExecutiveCmdExec account and stores it in an accessible portion of the registry, which could allow local users to gain privileges by reading and decrypting the CmdExecAccount value.

When a new SQL Server is registered in Enterprise Manager for Microsoft SQL Server 7.0 and the "Always prompt for login name and password" option is not set, then the Enterprise Manager uses weak encryption to store the login ID and password.

Microsoft SQL Server 7.0 and Microsoft Data Engine (MSDE) 1.0 allow remote attackers to gain privileges via a malformed Select statement in an SQL query.

The Mixed Mode authentication capability in Microsoft SQL Server 7.0 stores the System Administrator (sa) account in plaintext in a log file which is readable by any user, aka the "SQL Server 7.0 Service Pack Password" vulnerability.

Microsoft SQL Server allows local users to obtain database passwords via the Data Transformation Service (DTS) package Properties dialog, aka the "DTS Password" vulnerability.

Microsoft SQL Server 7.0 allows a local user to bypass permissions for stored procedures by referencing them via a temporary stored procedure, aka the "Stored Procedure Permissions" vulnerability.

Microsoft Enterprise Manager allows local users to obtain database passwords via the Data Transformation Service (DTS) package Registered Servers Dialog dialog, aka a variant of the "DTS Password" vulnerability.
