    Hello,
    In security advisor tells me failure to protect against symlink condition
    Since I have a Centos 6.7 server I would install the patch against symlink with cPanel hardened kernel but in the warning is written that you may experience reboots or even worse system failure .....
    I have to be more concerned about the symlink vulnerability or patch?
    There are steps possible to do before applying the patch to get in security? thank you !

    thanks Michael,
    i have started this thread after reading it. I want to know if i can get trouble applying this kernel patch and i want to know if there are possible tasks to do before for avoid system failure or reboots like described in documentation !
    i want to know system requirements, free memory needed , disk space needed, versions , file to backup,etc etc
    in other words a checklist !
    it is better to open a ticket?
    thanks

    Hello,

    No additional steps are required when installing the cPanel hardened kernel, beyond what's documented. Feel free to post the output from the following commands and we can verify if your system supports it:

    Code:
    uname -a
    cat /var/cpanel/envtype
    cat /etc/redhat-release
    arch
    Thank you.
