/**
* FIREBIRD REMOTE BUFFER OVERFLOW.
* ITDEFENCE.ru Proof-of-Concept (POC)
* Eugene Minaev (underwater@...efence.ru)
*
* 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
*
* src/remote/protocol.cpp:417
*
* MAP(xdr_short, reinterpret_cast<SSHORT&>(data->p_data_request));
* MAP(xdr_short, reinterpret_cast<SSHORT&>(data->p_data_incarnation));
* MAP(xdr_short, reinterpret_cast<SSHORT&>(data->p_data_transaction));
