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.

All is here : Dirty Cow

  • How can I know my kernel version

$ uname -rv

If your version is earlier than the following, you are affected:
4.4.0-45.66 for Ubuntu 16.04 LTS
4.8.0-26.28 for Ubuntu 16.10
3.13.0-100.147 for Ubuntu 14.04 LTS
3.2.0-113.155 for Ubuntu 12.04 LTS

  • How to fix this bug

Just do an apt-get upgrade


  • Am I in danger of hacking

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
