Project CentOS developer and maintainer Johnny Hughes announced the availability of a new, major, core security update for the 7 series of CentOS operating systems.
CentOS 7 is originally distributed and distributed freely from the source code of the business suite of Red Hat Enterprise Linux, which means it benefits from its security code.
According to the recent RHSA-2017: 0086-1 security advisory, which was marked as important, three vulnerabilities have been repaired.
Two of these security blanks are characterized as moderate and one important. For anyone interested in learning above, vulnerabilities are documented by codes CVE-2016-7117, CVE-2016-6828 and CVE-2016-9555.
To mitigate the risks, it is recommended that you install the new kernel-3.10.0-514.6.1.el7.x86_64 from the official repositories as soon as possible.
A regular update of your system will take care of this, but do not forget to restart your machine to work with the new kernel.
Below is the terminal screen you will see after updating your system if you choose to do it from the command line.
