Hi,
Excuse me if this has been already reported (though I couldn't find relevant information).
MS SQL Server 7.0 silently crashes when sent a TCP packet containing more than 2 NULLs as data.
Description:
I tested this on a machine running SQL Server version 7.00.699. The NT box is running NT Server with SP 4 (I don't think the Service Pack is an issue since NT is not affected).
If the TCP/IP net library is enabled, the 3 or greater NULL bytes crach SQL Server listening on port 1433. The SQL server raises an event 17055 with fatal exception EXCEPTION_ACCESS VIOLATION.
Can anyone reproduce this?
It's interesting to mention that:
- 1 or 2 NULL bytes don't affect the system.
- A nornal service restart will reboot SQL Server
Thanx.
Kevork Belian
