Summary
An issue was discovered in Fort before 1.6.3. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) an ROA or a Manifest containing a null eContent field. Fort dereferences the pointer without sanitizing it first. Because Fort is an RPKI Relying Party, a crash can lead to Route Origin Validation unavailability, which can lead to compromised routing.

"value": "Se descubri\u00f3 un problema en Fort antes de la versi\u00f3n 1.6.3. Un repositorio RPKI malicioso que desciende de un Trust Anchor (confiable) puede servir (a trav\u00e9s de rsync o RRDP) un ROA o un Manifiesto que contenga un campo de contenido electr\u00f3nico nulo. Fort elimina la referencia al puntero sin desinfectarlo primero. Debido a que Fort es una parte de confianza de RPKI, una falla puede provocar que la validaci\u00f3n del origen de la ruta no est\u00e9 disponible, lo que puede comprometer el enrutamiento."
