Those are kernel and kernel header updates which are major security updates for your system. Thus they are necessary in the security aspect. You can install them by command in terminal:

Open terminal by the key combination CTRL + ALT + T and enter these commands:

sudo apt-get update
sudo apt-get upgrade

And then reboot the system to have them taken effect.

you have kernel headers there so you should run

sudo apt-get update

sudo apt-get dist-upgrade

from the man apt-get

 dist-upgrade
   dist-upgrade in addition to performing the function of upgrade,
   also intelligently handles changing dependencies with new versions
   of packages; apt-get has a "smart" conflict resolution system, and
   it will attempt to upgrade the most important packages at the
   expense of less important ones if necessary. So, dist-upgrade
   command may remove some packages. The /etc/apt/sources.list file
   contains a list of locations from which to retrieve desired package
   files. See also apt_preferences(5) for a mechanism for overriding
   the general settings for individual packages

if you are notify you should remove some older dependencies run 

sudo apt-get autoclear && sudo apt-get autoremove

and here you have a complete apt-get guide
