parameters passed during an IKEv1 negotiation. An attacker could exploit this vulnerability by sending crafted
parameters.

Only traffic directed to the affected system can be used to exploit this vulnerability. This vulnerability only
affects systems configured in routed firewall mode and in single or multiple context mode. This vulnerability can
be triggered by IPv4 or IPv6 traffic. A valid IKEv1 Phase 1 needs to be established to exploit this vulnerability,
which means that an attacker would need to have knowledge of a pre-shared key or have a valid certificate for
phase 1 authentication.");
