SQL Server 7.0 SP4, 2000 SP4, 2005 SP1 and SP2, 2000 Desktop Engine (MSDE 2000) SP4, 2005 Express Edition SP1 and SP2, and 2000 Desktop Engine (WMSDE); Microsoft Data Engine (MSDE) 1.0 SP4; and Internal Database (WYukon) SP2 does not initialize memory pages when reallocating memory, which allows database operators to obtain sensitive information (database contents) via unknown vectors related to memory page reuse.

Integer underflow in SQL Server 7.0 SP4, 2000 SP4, 2005 SP1 and SP2, 2000 Desktop Engine (MSDE 2000) SP4, 2005 Express Edition SP1 and SP2, and 2000 Desktop Engine (WMSDE); Microsoft Data Engine (MSDE) 1.0 SP4; and Internal Database (WYukon) SP2 allows remote authenticated users to execute arbitrary code via a (1) SMB or (2) WebDAV pathname for an on-disk file (aka stored backup file) with a crafted record size value, which triggers a heap-based buffer overflow, aka "SQL Server Memory Corruption Vulnerability."

The "sa" account is installed with a default null password on (1) Microsoft SQL Server 2000, (2) SQL Server 7.0, and (3) Data Engine (MSDE) 1.0, including third party packages that use these products such as (4) Tumbleweed Secure Mail (MMS) (5) Compaq Insight Manager, and (6) Visio 2000, which allows remote attackers to gain privileges, as exploited by worms such as Voyager Alpha Force and Spida.

The registry key containing the SQL Server service account information in Microsoft SQL Server 2000, including Microsoft SQL Server Desktop Engine (MSDE) 2000, has insecure permissions, which allows local users to gain privileges, aka "Incorrect Permission on SQL Server Service Account Registry Key."

Buffer overflow in bulk insert procedure of Microsoft SQL Server 2000, including Microsoft SQL Server Desktop Engine (MSDE) 2000, allows attackers with database administration privileges to execute arbitrary code via a long filename in the BULK INSERT query.

Buffer overflow in the password encryption function of Microsoft SQL Server 2000, including Microsoft SQL Server Desktop Engine (MSDE) 2000, allows remote attackers to gain control of the database and execute arbitrary code via SQL Server Authentication, aka "Unchecked Buffer in Password Encryption Procedure."
