CVE-2024-45235

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 an Authority Key Identifier extension that lacks the keyIdentifier field. Fort references this 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.

Summary		(es) Se descubrió un problema en Fort antes de la versión 1.6.3. Un repositorio RPKI malicioso que desciende de un Trust Anchor (confiable) puede servir (a través de rsync o RRDP) un certificado de recurso que contenga una extensión de Identificador de clave de autoridad que carece del campo keyIdentifier. Fort hace referencia a este indicador sin desinfectarlo primero. Debido a que Fort es una parte de confianza de RPKI, una falla puede provocar que la validación del origen de la ruta no esté disponible, lo que puede comprometer el enrutamiento.
