Security is an ongoing matter for all the open system. So it's upto the guy who in charge of it and some company forces it too.In this article I will show you how you can fix the security hole in Gentoo.

Say you come to know that an security vulnarability has found on some particular and that software were loaded in your box.Here is how you can fix those:

....output is omitted for the sake of brevity, Yes,you spotted it right,glsa-check is an utility in Gentoo system to check security.Once it finished running then just run this command with different arguments; like below:

bhaskar@bhaskar-laptop_15:05:34_Tue Jan 25:~> sudo glsa-check -l affected
[A] means this GLSA was already applied,
[U] means the system is not affected and
[N] indicates that the system might be affected.

Now let me tell you that those alphabet in the left side within square bracket come with different colors. The A will be on normal white,the U will be green and the N in red.Important part to check how many N you have .

So,one tiny utility can do wonder,indeed.You can put it into the cron to run it periodically.

Hope this will help.
