Upgrade to Ubuntu Pro for a more secure system???

[kalpana]

Forgive me if this topic has already been discussed, but for about a week now I've been getting the following message whenever I update my software via the terminal:

Get more security updates through Ubuntu Pro with 'esm-apps' enabled:
libimage-magick-perl imagemagick libopenexr25 libmagickcore-6.q16-6-extra
libimage-magick-q16-perl libmagickwand-6.q16-6 imagemagick-6.q16
libeditorconfig0 libmagickcore-6.q16-6 imagemagick-6-common

So now I have to pay for a subscription in order to keep my PC secure??? Wow, just wow.
