    Hi,

    while testing racoon on Linux (based on the ported ipsec-tools) the
    following issue appeared:
    Racoon did not verify the RSA Signatures during Phase 1 in either main
    or aggressive mode.
    Authentication was possible using a correct certificate and a wrong
    private key.

    I have verified the below problem using racoon-20030711 on FreeBSD 4.9. I will test
    it using the SNAP Kit but suspect it to be vulnerable, too.

    Probably other implementations like racoon and MacOSX are vulnerable, too.

    On Linux the issue was resolved with the attached patch.

    Could you look into this?

    I would like to publish a Bugtraq report after the weekend, provided that you have confirmed
    that either your racoon is not vulnerable or you have patches available.

    Regards,

    Ralf
