A rather serious Linux kernel vulnerability (CVE-2017-6074) was publicized on Wednesday (2/22). This vulnerability has been present since 2006 so it affects a large number of systems and distributions, many of which are no longer maintained. Thanks to KernelCare, our servers were all patched within a few hours of this having been published without any service impact.
If you use or manage any other Linux systems, hosting related or otherwise, you should make sure that they have been patched as well. This vulnerability could ultimately result in a local user compromising the entire system. Likewise, if you’re using devices or operating systems that aren’t being maintained and thus won’t be patched at all, now would be a good time to upgrade.
While on the topic of security updates, I do also want to mention the critical WordPress 4.7.2 update that was released about a month ago. If you are running WordPress 4.7 and have some how managed to not upgrade to 4.7.2 by now, you should do so immediately.
As always, we will continue to stay on top of these security updates, keeping you safe and informed.
