therefore, affected by an out of bounds write vulnerability:

  - An Out-of-bounds Write vulnerability in WatchGuard Fireware OS 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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
