I've just read somewhere about "Dirty Cow" bug, and I'm a new user of Ubuntu 1604.
- How can I know my kernel version?
- How to fix this bug?
- Am I in danger of hacking?
Thanks you all for your helps.

@fkraiem The linked question was about What and this is about how to fix. – Anwar Oct 30 '16 at 11:05

@Anwar No, it was not, if you would read beyond the title. – fkraiem Oct 30 '16 at 11:07

@fkraiem Please, be nice. Not everyone reads every questions. That didn't notice that one before. From your link, I quickly glanced over it. No answers (despite being lengthy) explicitly shows how to fix that. One mentions to upgrade kernel, but You cannot assume that much smartness from a user who asked this question. Btw, I agreed after reading the question that it is a duplicate. – Anwar Oct 30 '16 at 11:52

What should I do? Delete this question? – f44 Oct 30 '16 at 12:24

Exploiting this bug means that a regular, unprivileged user on your server can gain write access to any file they can read, and can therefore increase their privileges on the system. More infos
