Descriptions

libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.

libxml2 2.6.32 y anteriores, no detecta correctamente la recursividad durante la expansión de una entidad en un valor de un atributo; esto permite a atacantes dependientes del contexto provocar una denegación de servicio (consumo de la memoria y la CPU) mediante un documento XML manipulado.
