At ospd_common.c, on the osdp_reply_name function, any reply id between REPLY_ACK and REPLY_XRD is valid, but names array do not declare all of the range. On a case of an undefined reply id within the range, name will be null (name = names[reply_id - REPLY_ACK];). Null name will casue a crash on next line: if (name[0] == '\\0') as null[0] is invalid. As this logic is not limited to a secure connection, attacker may trigger this vulnerability without any prior knowledge. This issue is fixed in 2.4.0."

En ospd_common.c, en la función osdp_reply_name, cualquier id de respuesta entre REPLY_ACK y REPLY_XRD es válido, pero la matriz de nombres no declara todo el rango. En el caso de un id de respuesta indefinido dentro del rango, el nombre será nulo (nombre = nombres[id_de_respuesta - REPLY_ACK];). Un nombre nulo provocará un bloqueo en la siguiente línea: si (nombre[0] == '\\0') ya que null[0] no es válido. Como esta lógica no se limita a una conexión segura, el atacante puede activar esta vulnerabilidad sin ningún conocimiento previo. Este problema se solucionó en 2.4.0."
