Descriptions

The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document, aka an XML Entity Expansion (XEE) attack.

El analizador REXML en Ruby 1.9.x anterior a 1.9.3-p550, 2.0.x anterior a 2.0.0-p594, y 2.1.x anterior a 2.1.4 permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de un documento XML manipulado, también conocido como un ataque de la expansión de entidad XML (XEE).
