"value": "Feedgen (python feedgen) before 0.9.0 is susceptible to XML Denial of Service attacks. The *feedgen* library allows supplying XML as content for some of the available fields. This XML will be parsed and integrated into the existing XML tree. During this process, feedgen is vulnerable to XML Denial of Service Attacks (e.g. XML Bomb). This becomes a concern in particular if feedgen is used to include content from untrused sources and if XML (including XHTML) is directly included instead of providing plain tex content only. This problem has been fixed in feedgen 0.9.0 which disallows XML entity expansion and external resources."

La biblioteca *feedgen* permite suministrar XML como contenido para algunos de los campos disponibles. Este XML ser\u00e1 analizado e integrado en el \u00e1rbol XML existente. Durante este proceso, feedgen es vulnerable a Ataques de Denegaci\u00f3n de Servicio XML (por ejemplo, XML Bomb). Esto se convierte en una preocupaci\u00f3n en particular si feedgen es usado para incluir contenido desde fuentes no confiables y si XML (incluido XHTML) es incluido directamente en lugar de proporcionar solo contenido de texto plano. Este problema ha sido corregido en feedgen versi\u00f3n 0.9.0 que no permite la expansi\u00f3n de entidades XML y recursos externos."
