Summary
Firebird to system zarządzania relacyjnymi bazami danych typu open-source. W wersjach przed 5.0.4, 4.0.7 i 3.0.14, serwer, otrzymując pakiet op_crypt_key_callback bez wcześniejszej autoryzacji, nie inicjalizuje handlera port_server_crypt_callback, co prowadzi do dereferencji wskaźnika null i awarii serwera.
Risk Assessment
Nieautoryzowany atakujący, znający jedynie adres IP i port serwera, może wykorzystać tę podatność do zablokowania działania serwera. Może to prowadzić do przestojów w usługach i utraty dostępności danych.
Recommendation
Zaleca się aktualizację do wersji 5.0.4, 4.0.7 lub 3.0.14, aby usunąć tę podatność. Należy również monitorować serwer pod kątem nieautoryzowanych prób dostępu.

Original NVD description (English source)
Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when the server receives an op_crypt_key_callback packet without prior authentication, the port_server_crypt_callback handler is not initialized, resulting in a null pointer dereference and server crash. An unauthenticated attacker who knows only the server's IP and port can exploit this to crash the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14.
