/**

* FIREBIRD REMOTE BUFFER OVERFLOW.

* ITDEFENCE.ru Proof-of-Concept (POC)

* Eugene Minaev (underwater (at) itdefence (dot) ru [email concealed])

*

* 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));
