Microsoft SQL Server pre-authentication buffer overflow
|mssql-preauth-bo (9788)||High Risk|
Microsoft SQL Server 2000 and Microsoft Desktop Engine (MSDE) 2000 are vulnerable to a buffer overflow. By sending malformed data to TCP port 1433, an unauthenticated remote attacker could overflow a buffer and possibly execute code on the server with SYSTEM level privileges.
Note: This vulnerability also affects Cisco CallManager, Cisco Unity, and Cisco Building Broadband Service Manager, which incorporate the use of either SQL Server 2000 or MSDE 2000.
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS02-056. See References.
For Microsoft SQL Server 2000:
Microsoft originally provided a patch for this vulnerability in MS02-056, but it was superseded by the patch released with MS02-061, and then superseded by the patch released with MS03-031.
For Cisco CallManager, Cisco Unity, and Cisco Building Broadband Service Manager: Refer to Cisco Security Advisory 2003 January 26 05:30 GMT for upgrade or patch information. See References.
