Workaround

To mitigate this issue, remove the `NetworkManager-vpnc` package if the vpnc VPN plugin functionality is not required on the system. This will prevent a local unprivileged user from exploiting the flaw. To remove the package, use the following command: `sudo dnf remove NetworkManager-vpnc` Note that removing this package will disable the ability to use vpnc-based VPN connections.
