Description

Ralf Spenneberg has reported a vulnerability in KAME Racoon, which can be exploited by malicious people to conduct MitM attacks (Man-in-the-Middle) or establish unauthorised connections.

The vulnerability is caused due to an error within the "eay_rsa_verify()" function in "crypto_openssl.c". During authentication using RSA signatures, this will result in only the X.509 certificate being validated in Phase 1, and not the RSA signature.

Successful exploitation allows a malicious person sending a valid, trusted X.509 certificate and an arbitrary RSA signature to be authenticated.
