Descriptions

It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611).

Se ha detectado que una biblioteca interna de Prosody para cargar XML basada en libexpat no restringe apropiadamente las funcionalidades XML permitidas en los datos XML analizados. Dada la entrada apropiada del atacante, esto resulta en la expansión de referencias de entidades recursivas de DTDs (CWE-776). Además, dependiendo de la versión de libexpat usada, también puede permitir inyecciones usando referencias de entidades externas XML (CWE-611).
