Microsoft SQL Server text message query buffer overflow
| mssql-text-message-bo (7724) |  High Risk |
Description:
Microsoft SQL Server is vulnerable to a denial of service attack caused by a buffer overflow in the functions that are used to create and display text messages. By creating and executing a specially-crafted query that calls one of the affected functions, the attacker could overflow a buffer and execute arbitrary code on the system with privileges of the SQL Server process or cause the service to fail.
Platforms Affected:
- Microsoft, SQL Server 2000
- Microsoft, SQL Server 7.0
Remedy:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin. See References.
For Microsoft SQL Server 7.0:
Microsoft originally provided a patch for this vulnerability in MS01-060, MS02-007, MS02-020, MS02-043, MS02-056, and MS02-061, but they were superseded by the patch released with MS03-031.
For Microsoft SQL Server 2000:
Microsoft originally provided a patch for this vulnerability in MS01-060, MS02-007, MS02-020, MS02-034, MS02-038, MS02-039, MS02-043, MS02-056, and MS02-061, but they were superseded by the patch released with MS03-031.
