The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk."}, {"lang": "es", "value": "Se identific\u00f3 un fallo en el analizador RelaxNG de libxml2 relacionado con la forma en que se gestionan las inclusiones de esquemas externos.

Esquemas especialmente elaborados o excesivamente complejos pueden causar recursi\u00f3n excesiva durante el an\u00e1lisis.
