UDP remote code execution in Linux <4.5

Fantastic, this is what I wanted to be doing with the rest of my day.

EDIT: https://people.canonical.com/~ubuntu-security/cve/2016/CVE-2...

Looks like Ubuntu already patched it for all supported versions so I'm good since I'm patched up to date on everything.

I wonder how much stuff out there isn't though.

Does it mean that virtually all (old) DNS servers could be potentially hacked now? If I don't run anything UDP based, am I safe?

Clearly it's a go-back-to-bed kind of day.
