We stopped the second Zombieload invasion

Update

To secure your CloudLinux 7 and CloudLinux 6 hybrid servers, you should proceed as we did with the previous MSD vulnerability: update microcode along with the kernel update.

For CloudLinux 7, run the command:

yum upgrade -y microcode_ctl && yum install kernel-3.10.0-962.3.2.lve1.5.27.el7 --enablerepo=cloudlinux-updates-testing

Hybrid, run the command:

yum upgrade -y microcode_ctl && yum install kernel-3.10.0-962.3.2.lve1.5.27.el6h --enablerepo=cloudlinux-hybrid-testing
