Descriptions

A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable).

Un error en libxml2 permite la inclusión de entidades XML con marcas de analizador por defecto (por ejemplo, cuando el "caller" no solicitó la sustitución de entidades, validación DTD, carga de subconjuntos DTD externo o los atributos DTD por defecto). Dependiendo del contexto, esto podría exponer una superficie de ataque de mayor riesgo en libxml2 que, normalmente, no sería accesible mediante marcas de analizador por defecto. Además, podría exponer contenido de archivos locales o de servidores HTTP y FTP (que serían inalcanzables de otra forma).
