CVE-2021-3761: Out-of-bounds Write

Any CA issuer in the RPKI can trick OctoRPKI into emitting an invalid VRP MaxLength value, causing RTR sessions to terminate. An attacker can use this to disable RPKI Origin Validation in a victim network (for example AS - Cloudflare) prior to launching a BGP hijack which during normal operations would be rejected as RPKI invalid. Additionally, in certain deployments RTR session flapping in and of itself also could cause BGP routing churn, causing availability issues.
