In the wake of the Dirty Cow vulnerability, should I run the
do-release-upgrade on the server which runs this forum?
Currently, the server is running Ubuntu 14.04.5 LTS. Hosted inside it is a docker container which runs the actual forum and all other related bits. This is pretty good at keeping itself updated via a magic button that I press when told to do so, so I’m not too concerned about the docker container, but the host server is no-doubt vulnerable?
I’ve already run an
apt-get update && apt-get upgrade, which I understand should be enough to patch Dirty Cow… But in doing so the server is inviting me to run
do-release-upgrade to upgrade to 16.04.1 LTS - and I’m not sure if I should.
I’m concerned that I don’t know enough about the server to fix any issues that the upgrade might cause, but equally concerned that at some point the LTS for 14.04 will expire, and I don’t really want to leave everything until the last minute.
I’d welcome feedback from anyone that actually understand what they’re doing (unlike me).
