Descriptions

In Apache Tika 0.1 to 1.18, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a denial of service attack.

En Apache Tika desde la versión 0.1 hasta la 1.18, los analizadores XML no estaban configurados para limitar la expansión de las entidades. Por lo tanto, eran vulnerables a una expansión de entidades, lo que podría conducir a un ataque de denegación de servicio (DoS).
