Descriptions

Prosody before 0.8.1 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

Prosody antes de v0.8.1 no detecta correctamente la recursividad durante la expansión de la entidad, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria y CPU) a través de un documento XML manipulado que contiene un gran número de referencias a entidades anidadas, un problema similar a CVE-2003-1564.
