CVE-2024-45238 Information

Description

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.
