Yesterday, a kernel flaw affecting many different Linux distributions
was announced: https://copy.fail. This issue allows unprivileged users to gain root privileges on unpatched systems. Since no updated kernel packages have
been released yet by Ubuntu, we have implemented the suggested workaround on all NLNOG RING nodes.
We have no indications that any RING nodes were compromised before we
implemented the fix. Should you notice any signs of the contrary, please
let us know.
