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 w= ill 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 y= ou have confirmed that either your racoon is not vulnerable or you have patches available.
