We’ve put together a quick guide to check for this vulnerability and fix it.

  1. 1Run system check

    Install the ‘ghost-checker’ file to your server by running the below commands:

    wget http://mirrors.uk.heg.com/ghost/ghost-checker
    chmod +x ghost-checker
    ./ghost-checker
    
  2. 2Fix system

    If the above check returns ‘VULNERABLE’ then you need to run an update on your server. If your server isn’t vulnerable then there’s nothing more you need to do.

    sudo yum clean all; sudo yum update glibc
    
  3. 3Reboot system

    After the above process has completed it’s important to reboot your machine to ensure all services restart without weaknesses.
