Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the xdr_status_vector() function does not handle the isc_arg_cstring type when decoding an op_response packet, causing a server crash when one is encountered in the status vector. An unauthenticated attacker can exploit this by sending a crafted op_response packet to the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14.

Firebird es un sistema de gestión de bases de datos relacionales de código abierto. En versiones anteriores a la 5.0.4, 4.0.7 y 3.0.14, la función xdr_status_vector() no maneja el tipo isc_arg_cstring al decodificar un paquete op_response, causando una caída del servidor cuando se encuentra uno en el vector de estado. Un atacante no autenticado puede explotar esto enviando un paquete op_response manipulado al servidor. Este problema ha sido solucionado en las versiones 5.0.4, 4.0.7 y 3.0.14.
