Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
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) a resource certificate containing a bit string that doesn't properly decode into a Subject Public Key. OpenSSL does not report this problem during parsing, and when compiled with OpenSSL libcrypto versions below 3, Fort recklessly dereferences the pointer. Because Fort is an RPKI Relying Party, a crash can lead to Route Origin Validation unavailability, which can lead to compromised routing.

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 contiene una cadena de bits que no se decodifica correctamente en una clave p\u00fablica del sujeto. OpenSSL no informa este problema durante el an\u00e1lisis, y cuando se compila con versiones de libcrypto de OpenSSL inferiores a 3, Fort imprudentemente elimina la referencia al puntero. 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."
