Vendor Statement
Clavister Firewall: Not Vulnerable
Clavister VPN Client: Not Vulnerable
The IKE protocol is not vulnerable to the Klima-Pokorny-Rosa attack, as it does not provide the necessary "clues" for the Bad Version Oracle to work with.
Even IKE with RSA encryption, which is an unusual IKE mode of operation that Clavister products does not do, should be immune to this attack.
