Descriptions
expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and exmpp before 0.9.7, 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.
expat_erl.c en ejabberd v2.1.7 y v3.x antes de v3.0.0-alpha-3, y exmpp antes de v0.9.7, no detecta correctamente la recursividad durante la expansión de la entidad, lo que permite a atacantes remotos provocar una denegación de servicio ( la memoria y el consumo de 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.
