AI-suggested

Until an official fix is released, organizations should monitor vendor communications for updates. No vendor advisory or official remediation level is provided at this time, so no specific mitigation steps can be recommended beyond awaiting a patch.

Description

The Security Gateway does not correctly validate a length value in certain IKE packets when NAT-T is used (4500/UDP). As a result, a specially crafted or malformed packet can cause the VPN processing service to terminate unexpectedly, leading to denial of service (temporary interruption of VPN negotiations/traffic).
