Description

This means that your system does not support "limit" match firewall rules.

Resolving This Vulnerability

You need to install the ASL kernel. ASL will install this by default, provided that you do not have kernel installs disabled on your system. If you do not have kernel installation disabled, then simply reboot your system into the secure ASL.

If you are not sure if you have kernel installation disabled, or if you have the ASL kernel installed, please see the kernel wiki article for guidance on checking your systems configuration to ensure you can install kernels, and how to install the kernel if you had your system configured to not allow kernels to be installed.

Notes for VPS Machines and Containers

Please note that VPS systems such as OpenVZ/Virtuozzo, and Docker do not have their own kernel. So if you are using a VPS technology you will not be able to install any kernel on the system. VPS technologies share the hosts kernel, and the VPS will inherit the vulnerabilities in that kernel. If you do not control the host, we encourage you to report this vulnerability to your hosting provider and ask they fix their kernel. One way to do this is for them to install the secure ASL kernel on the host.
