patch available.

  - DHCP can add routes to a client's routing table via the classless static route option (121). VPN-based
    security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical
    interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic
    that was expected to be protected by the VPN. (CVE-2024-3661)

Note that Nessus relies on the presence of the package as reported by the vendor.");
