CVE-2024-45235: Null Pointer Dereference
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.
