## Overview

An Out-of-bounds Write vulnerability in the WatchGuard Fireware OS iked process may allow a remote unauthenticated attacker to execute arbitrary code. This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.

If the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured.

## Affected

- `fireware >= 11.10.2, < 12.5.15`
- `fireware >= 11.10.2, < 12.11.6`
- `fireware >= 2025.1, < 2025.1.4`

## Remediation

Upgrade past the affected range:

- `fireware 2025.1.4`
