## Description

The KAME IKE Daemon Racoon, when authenticating a peer during Phase 1, validates the X.509 certificate but does not verify the RSA signature authentication, which allows remote attackers to establish unauthorized IP connections or conduct man-in-the-middle attacks using a valid, trusted X.509 certificate.
