Overview

github.com/cloudflare/cfrpki/validator/lib is a package of Cloudflare's RPKI Toolbox.

Affected versions of this package are vulnerable to Improper Input Validation. OctoRPKI lacks contextual out-of-bounds check when validating RPKI ROA maxLength values. Any CA issuer in the RPKI can trick OctoRPKI into emitting an invalid VRP "MaxLength" value, causing RTR sessions to terminate.
