Descriptions

The REXML module in Ruby 1.8.6 through 1.8.6-p287, 1.8.7 through 1.8.7-p72, and 1.9 allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML document with recursively nested entities, aka an "XML entity explosion."

El módulo REXML en Ruby 1.8.6 hasta la versión 1.8.6-p287, 1.8.7 hasta 1.8.7-p72, y 1.9 permite que atacantes, dependiendo del contexto, provocar una denegación de servicio (agotamiento CPU) a través de un documento XML con entidades anidadas recursivamente, también conocido como "Explosión de entidades XML".
