Vulnerability Note VU#552398
KAME Racoon IKE daemon fails to properly verify client RSA signatures
The KAME Racoon IKE daemon fails to properly verify client RSA signatures when using Main or Aggressive Mode during a Phase 1 IKE exchange.
Racoon is an IKE Key Management daemon that negotiates and configures a set of parameters for IPSec. When authenticating a peer in Phase 1 of an IKE exchange, Racoon can use pre-shared keys, RSA signatures, or GSS-API. When using RSA signatures for authentication, Racoon validates the X.509 certificate, but fails to verify the client RSA signature.
An attacker with access to a trusted X.509 certificate can conduct a man-in-the-middle attack or establish an authenticated IPSec connection using any private key to generate the RSA signature.
