A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) a resource certificate containing a Key Usage extension composed of more than two bytes of data. Fort writes this string into a 2-byte buffer without properly sanitizing its length, leading to a buffer overflow."

Un repositorio RPKI malicioso que desciende de un Trust Anchor (confiable) puede servir (a trav\u00e9s de rsync o RRDP) un certificado de recurso que contenga una extensi\u00f3n de uso de clave compuesta por m\u00e1s de dos bytes de datos. Fort escribe esta cadena en un b\u00fafer de 2 bytes sin desinfectar adecuadamente su longitud, lo que provoca un desbordamiento del b\u00fafer."
